What problem does it solve? Choosing between Circle's developer-controlled, user-controlled, and modular (passkey) wallets is confusing because each differs in custody model, key management, account types, and blockchain support. This Skill provides a structured decision guide so you pick the correct wallet architecture before writing any integration code. ## Core Features & Use Cases - Wallet Comparison Matrix: Compares custody, authentication, account types (EOA vs SCA vs Modular Wallet), gas sponsorship, and SDK architecture across all three Circle wallet types. - Step-by-Step Decision Guide: Walks through custodian selection, auth method, account type, and chain compatibility to arrive at the right wallet. - Scenario Mapping: Maps common scenarios (payment backends, consumer apps with social login, DeFi apps with biometric auth, NFT marketplaces, AI agents) to the correct wallet type and delegates implementation to the corresponding specialized skill. - Use Case: You are building a consumer app with Google login and gasless transactions on an L2; the guide directs you to user-controlled wallets with SCA and the Circle Paymaster. ## Quick Start Ask which Circle wallet type fits your application by describing your custody model, authentication method, and target blockchain.
