Open Wallet is an open-source standard for secure local, multi-chain wallet storage and policy-gated signing, launched by MoonPay on March 23, 2026. Open Wallet's Twitter Score is 21 out of 1000 as of August 2026, ranking #48,032 (top 10%) among 483,914 tracked accounts.
Open Wallet grew out of MoonPay's internal infrastructure work: the wallet layer powering MoonPay Agents was generalized across chains and runtimes and released under an MIT open-source license via GitHub, npm, and PyPI. The current specification, Open Wallet Standard v1.3.2, defines a unified format for local wallet storage, delegated agent access, and policy-gated signing using CAIP identifiers.
Open Wallet is local-first and self-custodial, keeping wallet keys on the user's device without requiring remote custody or cloud key management. Private keys are encrypted at rest, policy checks are applied before any signing operation, key material is handled in-process during decryption and signing, and wiped after use. Its access layer supports scoped API tokens alongside policy controls including spending limits, allowlists, and chain restrictions. The standard supports EVM networks, Solana, Bitcoin, Cosmos, Tron, TON, Sui, Spark, Filecoin, and XRP Ledger, and interoperates with agent-payment protocols including x402 and MPP by producing signed payment authorizations within wallet-level policy limits.
Open Wallet ships a CLI alongside Node.js and Python SDK bindings, with an interface designed for agent and developer-tool access. The project held the OWS Hackathon on April 3, 2026, drawing more than 600 builders, more than 250 submitted projects, and a $50,000 prize pool. Open Wallet has attracted backing from a broad set of ecosystem participants, including PayPal, OKX, Ripple, TRON, TON Foundation, Solana Foundation, Ethereum Foundation, Base, Polygon, Sui, Filecoin Foundation, LayerZero, Arbitrum, Circle, Virtuals, Dynamic, and others. Open Wallet has accumulated 3,132 followers as of August 2026 and published 473 posts since 2026. The account has been mentioned by 13 accounts a total of 18 times.
