What is Onyx Wallet?

Onyx Wallet is a non-custodial ERC-4337 smart-contract wallet built for the Onyx XCN Ledger, a Layer 3 on Ethereum and Base. Users send and receive XCN, ERC-20 tokens, and NFTs without paying gas — transaction costs are sponsored by an Onyx DAO grant that burns XCN in the background. Secured by Face ID and passkeys, no seed phrases required.
