Give your agent a walletfor real-world work.

Fund an agent. Watch every dollar.

Warden sits between your agent and the spend. It gives the agent a stablecoin wallet, then checks spend, provider, policy, and risk before any payment moves.

THE PROBLEM

Agents cannot do real-world work without money.

The moment an agent needs to search, query, compute, generate, or call a paid API, it needs a way to pay. Every option for handing it money is a bad one.

WITHOUT WARDEN, YOUR OPTIONS ARE BAD
  • 01 ✕Hand over your API keys.
  • 02 ✕Give it a raw private key.
  • 03 ✕Approve every paid call by hand.
  • 04 ✕Let it pay unknown services blindly.

None of that survives production.

HOW IT WORKS

Warden sits between the agent and the spend.

x402 · one loop

The agent asks.

Warden decides.

Only monitored actions get paid.

Under the hood it speaks x402: read the payment challenge, evaluate policy and risk, sign only if allowed, then record the result. The agent never touches a key.

OUTCOME GUARANTEES
  • →No policy, no spend.
  • →No approval, no signature.
  • →No unchecked provider, gets paid.
