ZKP2P is a trustless and privacy-preserving fiat-to-crypto onramp powered by ZK proofs. This (V2) repo is currently under active development. ZKP2P is currently live in Alpha which is a productionized version with audits and supporting Venmo, a popular P2P payment network in the US. Try it out at zkp2p.xyz

The network leverages zero-knowledge proofs to verify DKIM signatures in payment confirmation emails, enabling secure and private fiat-to-crypto transactions. Key features include:

• Privacy-First: Proves SHA256, email regex, and RSA without revealing sensitive email contents
• Trustless: No intermediaries or centralized authorities needed
• Venmo Integration: Currently supports Venmo for US-based transactions
• Actively Developed: Working on reducing proving times and adding more payment rails

We are collaborating with the Privacy and Scaling Exploration (PSE) group to advance zero-knowledge proving systems.

• Node.js v16+
• Yarn
• A Venmo account (for testing)

git clone https://github.com/zkp2p/zkp2p-v1-monorepo.git
cd zkp2p-v1-monorepo
yarn install

yarn dev

ZKP2P off-ramping requires submitting Venmo IDs on chain so the on-rampers knows where to send the payment. A Venmo ID is unique identifier (e.g. 1234567891011121314 up to 19 digits) for your Venmo account that is separate from your handle (@Venmo-User).

Methods to find your Venmo ID:

1. Email Method:

   • Open any Venmo payment receipt email
   • Click on 'Show original'
   • Search for user_id
   • Note: You may need to remove the 3D encoding prefix

2. Command Line Method:

   curl https://account.venmo.com/u/[YOUR_VENMO_HANDLE] | grep -o '"user":{"displayName":"[^"]*","id":"[0-9]*"' | sed 's/.*"id":"\([0-9]*\).*/\1/'

   Replace [YOUR_VENMO_HANDLE] with your Venmo username (without @)

To verify your ID, visit: https://venmo.com/code?user_id=[YOUR_VENMO_ID]
