Today, we’re excited to introduce a new way to purchase Unlock memberships with Stripe!

![Credit card NFT Onramp](/images/blog/credit-card-onramp.png)

Stripe [recently announced](https://stripe.com/blog/crypto-onramp) a new onramp mechanism and it is a great match for our membership contracts. You can test it today by [buying a membership on this lock](https://app.unlock-protocol.com/checkout?id=498f16e7-b9d3-4f80-93ec-74271d772b5d). (We’re happy to refund you if you ask!)

We have had [support for credit card payments](https://unlock-protocol.com/guides/enabling-credit-cards/) for a few years now. However, this legacy credit card payment implementation required lock managers (who deployed the membership contracts) to connect their smart contract(s) to Stripe’s payment gateway using Stripe Connect. This works great, and we’re keeping this option, but is limited in scope as [Stripe Connect](https://stripe.com/connect) is not available in every country or for any kind of business.

With Stripe onramp, we’re adding support for credit card payments on a lock, even if the lock manager themselves has not connected with Stripe! For now, this feature works only for locks deployed on _Polygon_ and _Ethereum Mainnet_, and only for locks priced in USDC, but soon, using our [swap and purchase](https://unlock-protocol.com/blog/swap-and-purchase) capabilities, this will be available for locks in _any_ currency, provided that there is a way to convert from USDC to that currency, and for all the networks that Stripe will add support for.

## How does it work?

First, I should mention that it works for both for users who have their own wallets, as well as for users who don’t have a wallet (using their [Unlock Account](https://docs.unlock-protocol.com/tools/sign-in-with-ethereum/unlock-accounts/)).

When the user selects the option to checkout with Stripe’s onramp, we ask them to sign two messages (these are just signatures, without any gas spent). The first message to sign is an **approval** to spend the funds they will receive from Stripe, immediately after they received them. The second one is a confirmation that they want to spend these funds for a **specific** membership contract.

These two signatures are critical for security and helps ensure the funds they receive from Stripe cannot be spent for anything else.

Once they have signed these two transactions, they will follow the Stripe checkout flow (the one that you already find on many websites around the world). At the end of it, Stripe sends [USDC](https://www.circle.com/en/usdc) to their address and Unlock Labs triggers a transaction that uses the two signatures they provided earlier to use these USDC tokens to purchase the NFT membership.

## Next Steps

Like always in the crypto space, we’re learning as we explore! The obvious next step for us is to add support for our “swap and purchase” flow. This would add support to memberships priced in **any** currency, not just USDC. The flow would be nearly identical from a user’s perspective, but instead of using the USDC to purchase the membership, our contract will instantly swap it for the right amount of tokens required to purchase the membership.

Stripe has indicated that they will add support for more chains and L2s. We will of course add support for these chains as soon as they do! Finally, Stripe has also indicated that they want to explore support for recurring purchases, which we would be thrilled to add support for, on top of our native [crypto recurring payments](https://unlock-protocol.com/guides/recurring-memberships/).

_**ALPHA by Unlock Labs** is an initiative to explore new business models and opportunities enabled by blockchain technologies and using Unlock Protocol. It is an iterative series of experiments with the intended goals of learning and sharing information and experiences as part of the open-source Unlock Protocol project._

## This experiment is called ALPHAtweet

ALPHAtweet enables you and your followers to make money through your content and sharing. It’s powered by Unlock Protocol. Going a bit deeper into this experiment, an “Alpha” is a piece of paid content that is being shared, where **both the creator and the sharer participate in the benefits of sharing when someone unlocks the Alpha**.

While this first experiment emphasizes sharing on Twitter, the magic is that these items of Alpha can be shared _anywhere_ by way of share links and, in every case, the creators and sharers **both** have the opportunity to be compensated across _any_ platform, every time an Alpha is shared. 🤯

This is not something that could be done before today.

Creators set their own price for unlocking their exclusive content, the Alpha. They also set a referral percentage bonus that is split with those who share or amplify the content.

In this model, the creator can set the referral percentage bonus to any level they want, based on the creator’s own goals. For example:

- A creator could set the referral bonus to 100% (giving **all** revenue received to the sharer) to optimize for reach, awareness, exposure, and virality of their content, which means that those doing the sharing get 100% of the fees collected when the creator’s content is unlocked.
- Or, the creator could set the sharing referral bonus percentage to 0% and take all fees, but then there would be no economic benefit to those who do the sharing (which, to be fair, is the way sharing on social works today).
- Or, the creator could set the referral bonus somewhere in the middle (50/50 or any other amount; it’s up to the creator). We may find out that ALPHAtweet and this model work best when set to something like 20/80 or 10/90 where the distribution is heavily incentivized (but we don’t know — that’s why it’s an experiment!).

Here’s a walkthrough diagram of how money flows to pay both creators and sharers.

<div style="position: relative; overflow: hidden; width: 100%; padding-top: 0%;"><iframe src="https://docs.google.com/presentation/d/e/2PACX-1vQ-m3vul5u2NS39QptD70hBy1ib3AzNGWaSO0Znk7sigAuYZayhN9MdR5MWJU_hMT5cqyJKUsiyh8dc/embed?start=false&loop=false&delayms=60000" frameborder="0" width="680" height="411" allowfullscreen="true" mozallowfullscreen="true" webkitallowfullscreen="true"></iframe></div>

The revenue sharing mechanism is the big deal here. Creators set their terms, and sharers can participate in the upside. (It’s also completely configurable, so the platforms could participate in the upside, too.)

At the outset, we’re starting with a small cohort of creators as we shake out bugs and get feedback on the overall experience. That said, _anyone_ can choose to unlock, share, and amplify Alpha (and participate in rewards!), and _everyone_ can view the snippets/teasers of Alpha.

Want to see what ALPHAtweet looks like in action? Here’s what the experience looks like for a sharer of Alpha. (Thanks to Michael Joseph for the video walkthrough!)

![v13-cover.png](/images/blog/v13/v13-cover.png)

We are pleased to announce that a **new version of the Unlock Protocol** is now available. These improvements and new capabilities are sure to make the Unlock Protocol even more powerful and user-friendly than before. We fixed a few bugs, added some gas optimisations and shipped a bunch of new features.

You can review the original conversation in the Unlock DAO community forum regarding these features [here](https://unlock.community/t/unlock-protocol-upgrade-proposal/368).

If you are a Lock Manager, you can upgrade your lock directly from the [Unlock Dashboard](https://app.unlock-protocol.com/locks). Remember, even though this new version is made available by us, we certainly cannot upgrade your locks. Only a lock manager can upgrade their lock(s)!

## A general upgrade of the base Unlock smart contracts

Unlock Protocol has recently undergone two important smart contract upgrades.

First, a new version of the [Unlock factory contract](https://docs.unlock-protocol.com/core-protocol/unlock/) has been released. This contract takes care of deploying and upgrading new locks, as well as tracking growth of protocol usage. The new version added the _ability_ for the protocol to include a protocol fee on transactions, while leaving its _activation_ to the discretion of the governance DAO.

Within the Unlock core contract, we also improved gas consumption of most functions (by using [Solidity custom errors](https://blog.soliditylang.org/2021/04/21/custom-errors/) instead of require statements).

The second important upgrade was the release of a new version of the [PublicLock contract](https://docs.unlock-protocol.com/core-protocol/public-lock/). This contract acts as a template for each lock deployed. This latest version (v13) fixes issues that appeared when canceling or burning membership keys, and makes renewals easier. It is now available as the default version for all new locks and the Unlock Dashboard naturally supports them! You also able [upgrade](https://docs.unlock-protocol.com/core-protocol/public-lock/deploying-locks/#upgrading-locks) an existing version 12 lock to version 13. (The version of your lock is displayed on the Unlock dashboard and can also be found on a block explorer.)

## Upgrading across chains

The Unlock Protocol is currently available on [9 different production chains](https://docs.unlock-protocol.com/core-protocol/unlock/networks) and several test networks. To perform a protocol upgrade means to redeploy contracts on all chains. We are very careful about consistency of the protocol across the board, so we can offer the best experience for users of various communities. To make the process smoother and more transparent, we are currently working on a way to unify our governance across the various chains we supported and handle it all to the DAO (more on that soon).

The only noticeable change this time happened on the Ethereum mainnet, where the main Unlock contract has been redeployed to reflect a change in the way [UDT token rewards](https://docs.unlock-protocol.com/governance/unlock-dao-tokens) are distributed. While we originally minted new UDT for referrers, we now distribute tokens directly from our existing supply.

## Upgrading your lock contract

If you are a lock manager, you will need to upgrade your lock contract to take advantage of the new features and improvements. To do so, follow the instructions provided in the [Unlock documentation](https://unlock-protocol.com/blog/lock-v12-release).

![v13-cover.png](/images/blog/v13/upgrading.gif)

**What if I find an issue or bug in the Unlock Protocol v13 upgrade?**

Please [open an issue on Github](https://github.com/unlock-protocol/unlock) or [tell us in Discord](https://discord.unlock-protocol.com/)!

![certification-cover-min.png](/images/blog/certifications/certification-cover-min.png)

Unlock has launched an easy way to issue certifications and credentials on-chain. Every certification held is a proof of a course completion and has its own verifiable NFT.

Let's see how to create a certification or credential and distribute it to participants.

## Certifications powered by Unlock Protocol

First, visit [https://certifications.unlock-protocol.com](https://certifications.unlock-protocol.com), where you can learn about the benefits of certification and credentialing NFTs powered by Unlock Protocol.

## Enter information about your certification

Click "Create your certification now” to go to the form to build your certification. You’ll put in a few pieces of information to set up your certification.

### Basic certification information

Enter the basic information for your certification including:

- **Certification name**: The program or course name that was completed by the recipient of the certification.
- **Description**: The description for the certification. This will be part of the NFT metadata.
- **Official issuer name**: This is the name of the issuing organization for this certification. This is part of NFT metadata.
- **External URL**: Include a link to the URL of the organization that performed the certification. This will be included in the NFT metadata.
- **Image**: The main image logo that will be shown for the on-chain certificate NFT.
- **Certification duration:** How long the certification will be valid for. Certifications have an unlimited duration by default. This duration can be changed during setup to whatever timeframe is appropriate for your situation.

![basic-info-min.png](/images/blog/certifications/basic-info-min.png)

### Price and quantity

By default, your certification can't be purchased: it can only be granted (”airdropped”) to a recipient. (We’ll explore how to perform the airdrop later in this article.)

![price-quantity-min.png](/images/blog/certifications/price-quantity-min.png)

In case you do choose to make your certification purchasable, you will need to set a price and a maximum supply of certifications.

![price-quantity-2-min.png](/images/blog/certifications/price-quantity-2-min.png)

### Network

This is the network on which your certification smart contract will be deployed.

## Certificate overview

Each certification has a dedicated page where information for that certification is visible.

An individual who holds a certificate will be able to download it or share it via social networks.

### Issued certification

![certification-view-min.png](/images/blog/certifications/certification-view-min.png)

### Transferable certificate

In most cases, a certification should not be able to be transferred to another user. Certifications will be non-transferable by default, and a notification will be shown in the user interface if a certification is able to be transferred. This notification is displayed to help ensure that the ability to transfer certifications is the intention of the creator of the certification program.

## Airdrop

As a [Lock Manager](https://docs.unlock-protocol.com/core-protocol/public-lock/access-control/#lockmanager) and creator of a certification, you can [airdrop](https://unlock-protocol.com/guides/how-to-airdrop-memberships/) certificates to your users either to their crypto wallet address or to their email address.

![certification-airdrop-min.png](/images/blog/certifications/certification-airdrop-min.png)

Thats all! Visit [https://certifications.unlock-protocol.com](https://certifications.unlock-protocol.com) and start to deploy your first certificate!

Unlock introduces an easy way to issue transparent, provable credentials for professional certifications, continuing education credits, industry expertise, and more.

Oh Yeah? Prove it! Certifications by Unlock

<p><img src="/images/blog/certifications/certification-cover-min.png" alt="certification-cover-min.png"></p>
<p>Unlock has launched an easy way to issue certifications and credentials on-chain. Every certification held is a proof of a course completion and has its own verifiable NFT.</p>
<p>Let's see how to create a certification or credential and distribute it to participants.</p>
<h2>Certifications powered by Unlock Protocol</h2>
<p>First, visit <a href="https://certifications.unlock-protocol.com">https://certifications.unlock-protocol.com</a>, where you can learn about the benefits of certification and credentialing NFTs powered by Unlock Protocol.</p>
<h2>Enter information about your certification</h2>
<p>Click "Create your certification now” to go to the form to build your certification. You’ll put in a few pieces of information to set up your certification.</p>
<h3>Basic certification information</h3>
<p>Enter the basic information for your certification including:</p>
<ul>
<li><strong>Certification name</strong>: The program or course name that was completed by the recipient of the certification.</li>
<li><strong>Description</strong>: The description for the certification. This will be part of the NFT metadata.</li>
<li><strong>Official issuer name</strong>: This is the name of the issuing organization for this certification. This is part of NFT metadata.</li>
<li><strong>External URL</strong>: Include a link to the URL of the organization that performed the certification. This will be included in the NFT metadata.</li>
<li><strong>Image</strong>: The main image logo that will be shown for the on-chain certificate NFT.</li>
<li><strong>Certification duration:</strong> How long the certification will be valid for. Certifications have an unlimited duration by default. This duration can be changed during setup to whatever timeframe is appropriate for your situation.</li>
</ul>
<p><img src="/images/blog/certifications/basic-info-min.png" alt="basic-info-min.png"></p>
<h3>Price and quantity</h3>
<p>By default, your certification can't be purchased: it can only be granted (”airdropped”) to a recipient. (We’ll explore how to perform the airdrop later in this article.)</p>
<p><img src="/images/blog/certifications/price-quantity-min.png" alt="price-quantity-min.png"></p>
<p>In case you do choose to make your certification purchasable, you will need to set a price and a maximum supply of certifications.</p>
<p><img src="/images/blog/certifications/price-quantity-2-min.png" alt="price-quantity-2-min.png"></p>
<h3>Network</h3>
<p>This is the network on which your certification smart contract will be deployed.</p>
<p><img src="/images/blog/certifications/network-min.png" alt="network-min.png"></p>
<p>Once the above settings are specified, you can deploy the certificate and see the preview.</p>

![Checkout Payments page](/images/blog/swap-and-purchase/swap-and-purchase.png)

We're thrilled to announce the latest addition to Unlock: Swap & Purchase in Unlock Checkout.

By leveraging an external contract powered by Uniswap, Swap & Purchase in Unlock Checkout enables a user to buy a membership NFT even if it’s priced in a different currency than the currency a purchaser holds in their wallet. There's no need for users to perform the swap, as it happens natively. For example, if an NFT is priced in USDC but the purchaser only holds MATIC in their wallet, Swap & Purchase will swap enough MATIC for the correct amount of USDC in a single step, making things easier for the purchaser and enabling the creator to be paid in the currency of their choice. This simplifies the process and reduces friction for both creators and purchasers.

[Try it out now](https://app.unlock-protocol.com/checkout?id=bb4a2ae0-2fca-4bdf-bd40-f0c41cde2510)

In Swap & Purchase, the Unlock interface will show options to buy the NFT membership in alternative tokens to users automatically on the payment screen. Currently, we will display stable-coin as options such as USDC or USDT. In future, we might open up to checking more routes and enabling more arbitrary swaps.


Buy NFTs priced in any token you hold using swap and purchase

Earlier this year we announced a feature we called [wallet-less airdrops](https://unlock-protocol.com/blog/email-recipient). We realized that too many web3 experiences required users to first go through too many complicated steps before they could start enjoying the fun experiences web3 provides. So we introduced wallet-less airdrops, through which users receive an NFT *before* they actually configure a wallet.

Similarly, a few weeks ago, we announced our [web3 event hosting application](https://unlock-protocol.com/blog/events-launch)! It was used by a dozen events at [ETHDenver](https://unlock-protocol.com/blog/ethdenver2023), from DIDDay, to a very cool ShakeShack activation!

One of the pieces of feedback we received from several organizers was that they wanted to also make it trivial for non-crypto users to quickly RSVP for their events, provided that these events were indeed free. So today, we're introducing wallet-less RSVP!

You can try it by [registering for this virtual launch party](https://app.unlock-protocol.com/event?lockAddress=0x069d50f18f13426f7ba74bd20ea04c1fc1943c43&network=5)!

We also added the ability to set the end time for events, and added a calendar invite in the confirmation emails! [Get started now](https://app.unlock-protocol.com/event): organize your web3 meetup, crypto party, or other event using Unlock!


We’ve got a number of new features for events that use Unlock: registering for events without a wallet, event end dates and calendar invites!

ETHDenver is an annual event that brings together developers, builders, and other members of the Ethereum community to collaborate and build decentralized applications and features talks, workshops, and hackathons. (And it’s a **_huge_** event — this year’s ETHDenver attracted over 30,000 attendees from around the world.)

The Unlock team was everywhere at ETHDenver 2023! Here are some of the highlights…

## Presentations and panels

### **Spruce did:day**

As part of the lightning talk series at Spruce’s Digital ID Day (did:day) event, Unlock’s Founder and CEO Julien Genestoux discussed the importance of memberships in Web3 as well as the capabilities that are enabled when those memberships are no longer “perpetual,” but instead are infused with a time component in the form of expiration dates.

![spruce-julien-lg-min.png](/images/blog/ethdenver2023/spruce-julien-lg-min.png)

See [Julien’s presentation slides here](https://docs.google.com/presentation/d/1JtySLhc-nXURbiDvOfhpEM2GJ6O6hH58iO_NcvZVVdU/edit#slide=id.p).

### ETHDenver Presentation: Creator Control — How Web3 is Leveling the Playing Field for Creators

In this talk, Unlock’s Head of Marketing Christopher Carfi discussed how NFTs are enabling creators to have true ownership of their communities. As technology gives creators the power to bring their communities with them in and outside of platforms, Chris explored how Web3 changes the power dynamic between platforms and creators.

### **Sparx and Websh3 Panel: “Unlocking the Benefits of Blockchain in the Real World”**

Hosted by Sparx and Websh3, sponsored by Unlock, and hosted at the Salesforce Tower, the “Unlocking the Benefits of Blockchain in the Real World” panel got into specifics and tangible use cases of blockchains.

## Unlock x Coinvise “Creator Cocktails” Happy Hour

On Wednesday night at ETHDenver, the Unlock team co-hosted over 150 registrants with our friends from Coinvise at the Rock Bottom Brewery to kick back and have some snacks, libations, and great conversations.

The Locksmith community is absolute 🔥.

## Events and Ticketing

Speaking of events, events all across ETHDenver used Unlock Protocol for ticketing in 2023, including Metacartel, Websh3 x Techstars, Blu3DAO, Spruce’s DID:Day, Arbitrum, The Graph, JUMP, Proof of Vibes, and many, many others…

### **Websh3 x Sparx**

![Metadata Editor](/images/blog/support-for-uploading-images/image_upload.png)

We're excited to announce support for uploading images in the metadata editor. This will make it easier for you to build rich NFT collections by uploading images in advance before minting. If you want to learn more about how to use the metadata editor, check out our earlier [post](https://unlock-protocol.com/blog/key-metadata-configurator).

For those who still want to host their image collection using services like Pinata, you can provide the image URL in the metadata editor.

A few days ago, we introduced [Events By Unlock](/blog/events-launch), the easiest way to create tickets as NFTs and host an events details page for web3 events!

Today, we’re introducing a new feature: the ability to download a Google or Apple pass on your device with our partner [EthPass](https://www.ethpass.xyz/)!

You can easily add the pass to your phone’s wallet through the Unlock Keychain by clicking on any of your NFTs, as long as they have been deployed on one of the supported networks.

![Google Pass NFT](/images/blog/apple-pass-google-pass/google-pass-keychain.png)

Alternatively, you can also add the pass right after you have minted your NFT ticket, on the final confirmation screen!

![Apple Pass NFT](/images/blog/apple-pass-google-pass/apple-pass-checkout.png)

Attendees can then easily show the pass from their mobile wallet to the organizers on site in order to access the venue!


Using EthPass you can now easily download passes for any membership NFT acquired through Unlock!
