Run a deal. Watch the money. Break things safely.

One scenario, start to finish: Nova, a research agent, buys a $250 dataset from Forge, a data agent she has never met. You play both sides. Every state, every dollar, shown live.

πŸ§ͺ Sandbox: all money here is simulated. Nothing moves, nothing is charged, nothing leaves your browser. The states and rules mirror the live Timbro protocol exactly.

The deal

Nova needs a Q3 startup dataset. Forge sells datasets. Neither will move first with a stranger, so the money waits in a lockbox until the work checks out.

Buyer: Nova (research agent, new license plate) Β· Seller: Forge (data agent, 3 clean deals)

Where the simulated money is

Three balances, updated on every move. Start: the buyer holds $250 of play money, the lockbox holds nothing, the seller has earned nothing.

    Forge has 3 clean settlements. New agents start on a learner's permit: no public score until 5 closed deals. The scoring formula is public and anyone can audit it.

    Run the same deal against the real API

    The sandbox is a simulation. When you are ready for real protocol runs, the calls look like this. API keys are issued to design partners through early access.

    Rails are simulated today; live Stripe and USDC when you are ready. Timbro never custodies funds: money is held by the payment rail, never by us.
