That's all it takes to buy something using UMP's mini app with Warpcast Wallet.

We've been busy this month.

We always highlight how smooth and easy it is to buy things with UMP.
But it's also one of the most private ways to shop online.
When you buy through centralized eCommerce platforms, your personal data doesn’t just go to the seller—it’s shared with payment processors, customer support platforms, fraud prevention services, and a long list of other intermediaries. Many of these companies store your data indefinitely, sell it to third parties, or leave it vulnerable to hacks and data breaches.
With UMP, only the seller receives your information—and only the data they need to ship your order. Your shipping address is end-to-end encrypted with the seller’s private key. To further protect buyers, we built a custom encryption scheme called Hermes, which introduces additional encryption via a secret key or password selected by the seller.

Crypto should be a better payment option than credit cards.
The reason it's not is because you all are selling things the wrong way.

🚀 We're excited to roll out not one, but two major new features on UMP.eth today—bringing us closer to our vision of a safe, secure, permissionless, and truly decentralized peer-to-peer marketplace.

On-chain Verified Reviews via EAS
We've built a review system on top of Ethereum Attestation Service. Now, every storefront can display verified, on-chain reviews.
Once a sale is complete, the buyer can leave a review, and prospective buyers can trust that the feedback is authentic—because all data is transparent and stored on-chain.
We have ambitious plans to expand this into the most robust and reliable review system in the world.

We just dropped the latest version of our storefront smart contracts, and we think it might just be the smoothest eCommerce buying experience in crypto!

We're proud of our XMTP integration, which facilitates private comms between buyers and sellers.
When you buy something on UMP, the only person who can see your shipping address is the seller.
Compare that to traditional eCommerce where the seller, their payment processor, e-mail providers, a bunch of other random 3rd parties can all share, sell or leak your data.

Group chat, but make it truly secure and private. 🔒 💬 👥
XMTP now supports group chat powered by MLS (Message Layer Security), the IETF standard for end-to-end encrypted messaging.
Your conversations, your privacy—protected at every layer.

Making your 1st purchase on UMP is easy:
1. Select the listing you want to buy, purchase and send the transaction.
2. Go to the order history tab and send the seller your mailing address.
Your payment is held in an escrow contract and you'll be refunded if anything goes wrong.

We’re thrilled to announce the launch of Universal Market Protocol (UMP), a decentralized marketplace for tangible goods on Base! 🎉
UMP leverages smart contracts to create a privacy-preserving, secure marketplace.
How Does UMP Work?
At its core, UMP ensures that funds are securely held in a 2-of-3 multi-signature escrow contract until:
1. The buyer confirms receipt of their item OR
2. A dispute is resolved by a trusted arbiter.
UMP is designed to grow with our users. We plan to expand its modular design to support:
💸 Auctions.
🔒 Advanced escrow models.
😇 A robust trust system.
Please read more about in our post on mirror: https://mirror.xyz/ump.eth/G7iqVpaIldNyVI2dWSM-zcr-1aTpcmK5C2fpqiKLU7k
Or if you just want to get straight to trying it out, visit our storefront and buy a DEGEN Wassie sticker here: https://www.ump-eth.xyz/listings?address=0xED9f60c94bc61D4645CAB40edD9D826d28c93a68
