Our Picks
Open-source, free, and the most popular agent wallet. Built-in MCP server means it works with Claude out of the box. The largest community and most tutorials. Start here unless you have a specific reason not to.
Pick this if: You're building your first agent wallet, or need open-source.
80+ chains is unmatched. Pact guardrails give enterprise compliance teams the control they need — structured agreements, not just policy flags. The tradeoff: not open-source, and "contact sales" pricing.
Pick this if: You need 10+ chains, or your compliance team needs auditable agent guardrails.
USDC-native with gas sponsorship (Circle Gas Station). If your agent primarily holds and moves stablecoins, Circle's infrastructure is purpose-built for that. Enterprise-grade reliability.
Pick this if: Your agent's primary currency is USDC, or you need gas sponsorship.
Server-side wallets with no UI required. Built for backend agents that don't interact with humans. Policy engine for spending rules. Cross-chain with fiat on-ramp.
Pick this if: Your agent runs headless on a server with no user-facing wallet UI.
FAQ
What is the best MPC wallet for AI agents?
Coinbase AgentKit is the best starting point — open-source, multi-chain, and integrates with LangChain and Vercel AI SDK. For enterprise needs with 80+ chains, Cobo Agentic Wallet offers the broadest chain support with Pact guardrails.
Is MPC or smart account better for AI agents?
MPC wallets (Coinbase, Circle, Cobo) give agents full signing authority with key splitting for security. Smart accounts (MetaMask, Safe) offer scoped permissions and multi-sig. MPC is simpler for fully autonomous agents; smart accounts are better when you need granular user-delegated permissions.
Which MPC wallet supports the most blockchains?
Cobo Agentic Wallet supports 80+ blockchains. Coinbase AgentKit supports 5 major chains (Base, Ethereum, Polygon, Arbitrum, Solana). Circle supports 4 chains (Ethereum, Polygon, Solana, Avalanche).
Do MPC wallets work with Claude Code?
Yes. Coinbase AgentKit has a built-in MCP server that works directly with Claude Code. Cobo integrates via Claude MCP protocol. Other MPC wallets can be accessed via their REST APIs.
