Smart-wallet banking-as-a-service for partners

The client is a regulated crypto-payments company. It wanted to turn the wallets, compliance and rails it ran for its own customers into a platform that partners could build on.

Every partner wanted the same hard things: a wallet the user controls, onboarding that satisfies KYC/AML, and fiat and crypto rails. None of them wanted to build those, so the platform had to make them a product behind one API.

We built the layer on an EVM chain, Base, around account-abstraction smart wallets. That made the wallet self-custody without making it a burden. KYC/AML lives in onboarding, so a partner inherits compliance instead of re-implementing it. We shipped retail and business dApps over the same API as reference products.

Later we extended the platform to XRPL, using its native multisig for custody, and added wrapped USD and EUR stablecoins, backed 1:1 by the major issuers' coins, that earn yield through DeFi vaults. We ran the vendor selection and RFPs behind them.

More than 18 partners now run their own retail or business products on the layer, across two chains.
