Simulated money. The control loop is real.

Sandbox

Register, create a WAD, fund it with a simulated deposit, pair Claude Code, request a payment, approve it, read the receipt, freeze the agent. Target: under ten minutes. No real USDC moves. No custody.

Invite only

Live

The live pilot holds real USDC on Base for invited operators. Dedicated RPC, spending caps, and a verified exit are still open gates. Not open for public deposits.

Claude Code

One command. No install.

claude mcp add --transport http -s user wad \
  https://<host>/mcp \
  --header "Authorization: Bearer <token>"

Four tools: balance · create payment · get · list.

The token comes from the console after you create a WAD and pair an agent. It is a bearer credential — treat it like a password.

A decision you can inspect

The control receipt

WAD explains each approval and block against the policy you set, in plain language.

Quickstart

From zero to freeze

  1. Open the sandbox. Create a passkey.
  2. Create a WAD. Set the human-approval threshold to $1.
  3. Credit a simulated deposit of 5 USDC from Deposits.
  4. Create and pair an agent. Copy and run the MCP command in Claude Code.
  5. Ask the agent to pay $1 to a labeled payee. Approve with your passkey. Read the receipt.
  6. Freeze the agent. Confirm a later request is refused.
