Developer demonstrates major smart wallet updates for Soroban including P256R1 and ED25519 signing curves, multi-signature support, and policies that restrict signer capabilities without requiring transaction pop-ups.
A developer showcases significant enhancements to the passkey kit for Soroban smart wallets. New features include support for P256R1 (WebAuth/passkeys) and ED25519 (classic Stellar) signing curves, multi-signature capabilities allowing multiple signers per invocation, and policies that act as smart contracts to restrict what signers can do. The demo shows how policies can enable interactionless signatures while maintaining security by limiting signer permissions to specific actions like math operations, preventing unauthorized transfers. This approach mirrors Web2 OAuth patterns and enables use cases like subscription services, bot claims, and temporary signers with expiration dates.
