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

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?

I think switching up formats is a tough problem to deal with, so I agree. But yeah, the censorship risk is probably the bigger one.

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
