01Goal
Give people a bank-style app for holding, sending, and saving USDC, with no seed phrase and no custodian holding their funds.
02Description
A consumer app on a passkey smart wallet. Users hold USDC, send to handles, set spending rules, and park money in goal-based savings pots. Licensed anchors handle cash in and cash out.
03Key features
- 01Passkey-secured wallet with a USDC balance.
- 02Send and request by handle or QR.
- 03Savings pots with goals and lock rules.
- 04Spend limits and a payee allowlist enforced on-chain.
- 05Cash in and out through an anchor, plus statement export.
04Technical direction
A Soroban custom account contract for spend rules, and a separate vault contract for pots using the SEP-41 token client. Anchor integration through SEP-10 auth and SEP-24 interactive flows, so KYC stays with the anchor. An indexer for history. Check regulatory scope before offering fiat features.

Shows what Stellar is built for: stablecoin payments, a global anchor network, and financial inclusion.
06Use cases
