Developer walkthrough of Stellar smart wallet implementation using Soroban, covering passkey signers, policy-based access control, and stateful contract patterns for secure multi-sig account management.
This is a technical coding session demonstrating smart wallet architecture on Stellar's Soroban platform. The speaker covers passkey integration (SECP256R1), ED25519 signers, and policy-based signing limits that allow safe delegation of secret keys with restricted permissions. Key topics include stateless policies (simple contract restrictions) versus stateful policies (complex multi-wallet scenarios with spending limits), the check_auth authorization flow, context stacking in cross-contract calls, and practical examples like the safeguard contract that enables sub-wallets with per-interval spending caps. The discussion addresses domain-bound passkeys, fee sponsorship models, and design philosophy around user experience for blockchain adoption.
