What is a Non-Custodial Wallet?
A non-custodial wallet is a cryptocurrency wallet where the user (or operator) retains exclusive control of the private keys, with no third party able to access, freeze, or move the funds.
WHY IT MATTERS
Non-custodial wallets embody crypto's core principle: financial sovereignty. You hold the keys, you control the funds. No custodian can freeze your account, deny withdrawals, or lose your money through mismanagement.
This sovereignty comes with responsibility. Lose your private key or seed phrase, and the funds are gone permanently. There's no 'forgot password' recovery. For individuals, this is manageable with proper backup practices. For organizations running agent fleets, key management becomes a critical operational concern.
For AI agents, non-custodial wallets are the preferred approach. The operator retains key control while using smart contracts or policy layers to constrain what agents can do. This preserves sovereignty while adding the spending controls agents need.
HOW POLICYLAYER USES THIS
PolicyLayer is designed specifically for non-custodial wallets. Operators keep their keys while PolicyLayer adds programmable spending controls through smart contracts — the best of both worlds: full custody with bounded agent behavior.
