Definition
Wallet-as-a-Service (WaaS) provides managed onchain wallet infrastructure so banks, fintechs, and payment providers can hold and move digital assets without building their own key-management and blockchain stacks.
Key Points
- 2026-07-16: visa ships WaaS as part of visa-stablecoin-platform (VSP), initially for open-usd / OUSD (2026-07-16-visa-stablecoin-platform-businesswire)
- Typical bundle: custody/wallet ops + mint/burn/transfer connectivity to a stablecoin issuer stack
- Fits institutional preference for Visa-managed environments over self-run nodes
- Complements settlement rails and stablecoin-linked cards rather than replacing them
