LeP2P

Introducing LeP2P: A Peer-to-Peer Sybil-Resistant Decentralized Fiat On/Off-Ramp for Crypto application that offers a secure and user-friendly platform for trading fiat for cryptocurrencies.

It employs Worldcoin for Sybil-resistance: enhancing security and trustworthiness.

The platform utilizes smart-contract escrows for seamless, intermediary-free transactions.

LeP2P sets initial transaction limits for Worldcoin ID holders at 1,000 euros and requires KYC verification for higher amounts.

The interface is designed to be user-centric and accessible to users of all levels of expertise.

We also store the payment through Web3 Storage, tapping Filecoin and IPFS

Technologies used:

• WorldCoin for the user authentication so that we can ensure that the app can only be used by real humans.
• Web3Modal for Wallet Connections
• Quicknode as our Node RPC Provider
• Polygon ID for leveraging verifiable credentials, which for our use case, is a KYC that unlocks for bigger volume in our protocol
• AirStack for querying XMTP enabled wallets
• Push Protocol for Push Notifications in the app for offer creation, completion, cancellation
• Web3Storage: IPFS + Filecoin for decentralized hosting of payment proofs
• The Graph: Indexer for our contract events that serve the protocol current orders and updates them accordingly
• Polygon Mumbai for our contract deployments
• Foundry for smart contract development + deployments + testing
• Next.js with Wagmi + viem for contract interactions in the front-end (shadcn + tailwind <3)
