Use Cases
Trading Desks
Leveraged macro from the stablecoin balances a desk already holds.
A desk that already holds USDC should not need a futures account, a prime broker, and a gas tank to take a view on gold, NDX, or EURUSD. Gateway is leveraged exposure on those markets from collateral you already have. Sign an intent. Get a terminal answer in about 0.7 seconds, at the price you saw when you decided. No ETH on the trading path.
Cumulative cleared volume
Direct or embedded
Call the API from the desk, from an execution stack you already run, or from an agent over MCP. The order is the same signed intent either way. The path does not care whether a person or a process sent it.
Collateral you hold
Onboarding relays a USDC permit and delegation in one call. After that, trading is gasless. Proceeds settle to the trader's address. You do not open a new account at a new venue in a new asset to take the view.
Institutional reporting
A fill is a tradeId, a price, and amounts. A reject is a decoded reason. You record the terminal state. You do not reconcile a transaction that might still be in flight.
What a desk stops holding open
Accounts and rails
The usual path to a gold or FX position is a chain of accounts: a futures relationship, a funding rail, sometimes a separate venue per asset class, and, if the venue is on-chain, ETH sitting there so the next order can pay for itself. Gateway collapses the market side of that chain to a signed intent. The desk keeps its own books. It does not keep a wallet of gas for each trader.
The delegate contract can only execute orders that carry the trader's EIP-712 signature, every field signed. A compromised relay cannot redirect funds. Settlement is back to the trader's address. Short deadlines and one-shot random nonces mean a replay is not a position.
If something fails you have a decoded reason, not a hash to chase. There is no pending-in-mempool middle to reconstruct. That is also why twelve days of automated testing closed cleanly: every open had a matching close, including through two stage incidents the integration traded through on purpose.
Collateral
You post stablecoin collateral and you trade. There is no conversion into a clearing-house coin, and no second margin account in a name operations has to remember. Onboarding is a USDC permit and delegation in one call. After that, trading needs no ETH.
A per-size executable quote tells you the price for the clip you want. In fifty tick-triggered round trips against a recorded tape, predicted fills matched to 0 bps. The feed under that quote ticks at about 465 milliseconds median, snapshot on connect, largest gap 1.8 seconds on a three-minute tape. You decide on a print you can still see.
Eighty-three instruments sit behind that quote: crypto, FX, indices, commodities, ETFs, and single stocks, same five endpoints. Gold on Monday and NDX on Tuesday do not require a second relationship.
Execution and reporting
POST /v1/orders returns filled (tradeId, price, amounts) or reverted (decoded reason). No gas, no polling, no partial states. Across about 1,900 live production orders the path never returned an ambiguous result. Wall time was about 0.7 seconds on warm connections with websocket-cached pricing. Observed round-trip cost at $5 test size was about ten cents, about $19 across 200+ real orders. Test-size economics. Live orders, not paper. You record the terminal state. You do not chase a transaction that might still be in flight.
When latency showed up in stage benchmarks on a Monday it was better the same day and resolved by Thursday, a 60% median improvement under load, verified on re-runs. The signing layer is contract-verified. The path is live.
