Peanut Protocol is a digital platform facilitating token transfers through URLs. It employs secret-protected vault smart contracts, enabling users to deposit tokens into a vault and share a secure URL with recipients for fund withdrawal. The protocol supports various token types, including native tokens, ERC-20s, and NFTs (ERC-721s and ERC-1155), across multiple EVMs. It offers features like Multilink and cross-chain claim links, and is open-source, inviting contributions from developers.
