Coinbase AgentKit vs Turnkey

MPC open-source toolkit vs TEE-based enterprise wallet infrastructure

wallet MPC open source enterprise

Best for: Developers choosing between fast-start agent tooling and policy-heavy enterprise custody

Quick verdict

Pick Coinbase AgentKit if you want open-source code, MPC custody, the fastest path to a working agent wallet, or need Base or Arbitrum support.

Pick Turnkey if you are an enterprise requiring TEE-based security with strict policy rules, and your use case is limited to Ethereum, Polygon, or Solana.

The two are not interchangeable: they differ in custody model (MPC vs TEE), source availability (open vs closed), and target user (builders vs enterprise).
