Three account modes are supported - smart-account (Nexus / ERC-4337), eoa (MetaMask, Rabby, Trust funded by an explicit fundingToken), and eoa-7702 (EIP-7702 set-code delegation for Privy / Dynamic / Turnkey embedded wallets). Composable instruction types include intent-simple, intent, intent-vault (200+ DeFi vaults), build, build-raw, and build-ccip. - aid: biconomy:biconomy-bundler-api name: Biconomy Bundler API tags: - Account Abstraction - ERC-4337 - Bundler - UserOps humanURL: https://github.com/bcnmy/bundler properties: - url: https://github.com/bcnmy/bundler type: SourceCode - url: https://docs.biconomy.io/contracts-and-audits/supported-chains type: Documentation description: Biconomy's open-source ERC-4337 TypeScript Bundler.
