use-modular-wallets

Overview Modular Wallets are flexible smart contract accounts (MSCAs) that extend functionality through installable modules. Built on ERC-4337 (account abstraction) and ERC-6900 (modular smart contract framework), they support passkey authentication, gasless transactions, batch operations, and custom logic modules (multisig, subscriptions, session keys). MSCAs are lazily deployed -- gas fees for account creation are deferred until the first outbound transaction. Prerequisites / Setup Installation npm install @circle-fin/modular-wallets-core viem For passkey recovery, also install: npm install bip39 Environment Variables Show more
