Ok zkp2p.xyz is tremendously impressive. Pay with Venmo, get USDC on Base.

Uses a very clever zkemail to prove your venmo transfer.

Try it—works best on desktop

there is a fundamental trust assumption on the mail server doing the dkim signing I think

but this probably isn’t an issue until size where Venmo is incentivized to forge +sign emails to mint usdc

the way that last risk would materialize is not Venmo/Paypal stealing USDC (they would never), but rather some FUD around illegal use of zkp2p > Venmo intentionally starts rotating their DKIM key to avoid being used that way

/// echo.xyz ///

Or they start switching up their email format, freezing involved venmo accounts etc 

Point is just—there is no real risk of Venmo intentionally rugging USDC from zkp2p. only a risk that they’ll eventually try to deny service

From the conversation I’ve had with the team, DKIM keys being rotated is baked into the design of zk-email. Are you concerned with the frequency of rotations?

"they would never is" is never how we should talk about trust assumptions even if in practice they would never
