Introducing OWS, the Open Wallet Standard
MoonPay's Open Wallet Standard (OWS) is a local-first key management protocol designed to serve as the wallet layer beneath emerging agentic payment standards such as x402, MPP, and A2A, which define how agents transact but leave private key storage unspecified. OWS derives accounts for EVM, Solana, Bitcoin, Tron, TON, and Cosmos from a single BIP-39 seed, encrypts keys with AES-256-GCM using scrypt KDF, holds decrypted material in encrypted memory, and zeroizes it after signing. Local signing reduces per-signature latency from 100-175ms to microseconds while eliminating custodial dependencies, vendor lock-in, and recurring costs for teams running self-hosted agent infrastructure. The standard launched with 21 founding organizations spanning multiple ecosystems, including PayPal, OKX, Circle, the Ethereum Foundation, the Solana Foundation, Base, Ripple, and Polygon.
