TokenSight is related to on-chain smart contract wallet security solution, and the approach is focused on two overlapping directions - creating an ERC-4337 smart contract wallet with a WebAuthn device, and providing developer tooling for adding WebAuthn device as a multifactor transaction authorization mechanism to existing ERC-4337 wallets. TokenSight approach is based on full on-chain implementation for a gas cost optimized WebAuthn signature verification scheme without utilizing any kind of MPC architecture, thus providing maximum security and decentralization.
