Send BTC to an Email Address

What is BOB Pay?​

BOB Pay aims to showcase how easy crypto UX can be by focusing on a simple use case popular within the Bitcoin ecosystem: payments.

With BOB Pay, you can send Bitcoin and stablecoins to someone's email address. No wallet, no app, no seed phrase - just simple, cheap, non-custodial, and lightning-fast payments. BOB Pay showcases the power of wallet abstraction with Dynamic, smart accounts from ZeroDev, and paymasters from Pimlico.

We’re offering projects on BOB free access to Dynamic and Pimlico if you’d like to do the same.

Video Tutorial​

High-Level Technical Summary​

  1. Alice logs into BOB Pay and sends WBTC to John's email address.
  2. Dynamic generates a deterministic ZeroDev smart account wallet for John on BOB.
  3. John claims their WBTC by sending their first transaction to Charlie. The transaction fees are paid to a Paymaster in WBTC so John can transact without holding any ETH.
  4. A guarantor from Pimlico sponsors John's first transaction fees, then claims back the funds after John's first transaction. This solves the problem of John needing ETH to approve the Paymaster's access to their WBTC.
