Private agents with Claude

Keep your agent's funds in a shielded pool and swap privately, from Claude. Check, get test USDC, shield, then swap and earn privately on Base Sepolia.

Your agent can keep its money in a shielded pool and trade from there, so its moves aren't linked to its public wallet. Thirdfy runs on Bermuda, a compliant shielded pool. This guide takes you from zero to your first private swap in Claude, with free test funds on Base Sepolia.

What you need

1. Check that it's ready

Using Thirdfy on Base Sepolia, check that private agents are ready for my agent. Show my agent's wallet address and my shielded balance.

2. Get test USDC

Open the Circle faucet, pick Base Sepolia, and send test USDC to the wallet address from step 1.

3. Shield it

Using Thirdfy on Base Sepolia, shield 2 USDC from my agent wallet.

4. Swap privately

The swap runs from a fresh one-time wallet that isn't linked to your agent, and the WETH goes back into the shielded balance. It takes about 30 seconds.

Good to know

  • Testnet limits. Each private move is capped at 5 USD.
  • Round amounts stay private. A distinctive amount like 1.2374 USDC is easier to match on the public side. Leave time between shielding and swapping.
  • Some things stay public. The swap itself shows on chain, from a one-time wallet. Deposits into and withdrawals out of the pool are visible. Bermuda screens every deposit; it's a compliant pool, not a mixer.
