Phase one of on-chain trading runs on a **preview host** against **Base Sepolia**. It is a test environment: the tokens have no value and the database can be reset. On this host every order in `OOM` or `USDC` must carry an EIP-712 `LimitOrderIntent` signed by the Safe owner. HMAC alone cannot create an order. Production (`https://api.futuur.com`) does not accept the on-chain fields yet. ## Host | | Value | | - | - | | API base URL | `https://web3-phase-01-preview.staging.cloud.futuur.com/v2.0` | | OpenAPI schema | `https://web3-phase-01-preview.staging.cloud.futuur.com/docs/schema/` | | Trading halt flag | `GET /v2.0/trading-status/` (no auth) returns `trading_halted` | Paths end with a trailing slash, for example `POST /v2.0/orders/`. ## Chain | | Value | | - | - | | Network | Base Sepolia | | Chain ID | `84532` | | Public RPC | `https://sepolia.base.org` | | ERC-4337 EntryPoint (v0.7) | `0x0000000071727De22E5E9d8BAf0edAc6f37da032` | `chain_id` is optional on every endpoint that takes it and defaults to the active chain. A different value is rejected. Base mainnet (`8453`) is not active on this host. ## Tokens and pool | Role | Address | Decimals | Notes | | - | - | - | - | | `USDC` collateral | `0xA10E77cF8E1F71a44D374646AF5fd9641C5161Bd` | 6 | A mintable mock USDC (MUSDC), not Circle USDC | | `OOM` collateral | `0x9e89a2c1dA308052EFAF590e71bEfF256AF9F7a4` | 6 | Restricted ERC-20. Transfers and spenders are allowlisted by the token admin | | Pool (clearing Safe and `approve` spender) | `0xbC42f13000Da4D895cB5dD9375511846332A5053` | — | Holds collateral between match and payout | > [!WARNING] > > Treat the API as the source of truth for these addresses. `POST /orders/signing-context/` and `GET /me/safe/trading-status/` return `poolAddress` and `collateralToken` for your request. Use those values when you build an `approve`, and stop if they differ from this table. Amounts on-chain use 6 decimals for both tokens: `1 USDC = 1000000` raw units. ## Get test funds | Asset | How | | - | - | | OOM | Minted to your Safe by the platform after the Safe is deployed. A new account receives 10,000 OOM. You cannot mint OOM yourself. | | USDC (MUSDC) | Minted by Futuur staff. Ask the Futuur team for a test mint to your Safe address. `[PLACEHOLDER: contact channel for test USDC]` | | Gas | UserOperations sent through the Futuur relay (`/me/safe/sponsor-user-operation/`) can be sponsored, so the Safe does not need ETH for them. | Check what arrived with `GET /me/safe-wallet/?refresh=1` and `GET /me/balances/`. ## Account requirements * Your account has a `wallet_address` (the owner EOA). You get one by signing in with that wallet. * Your Safe is registered and deployed. See [Safe wallet](https://docs.futuur.com/api-reference/me/safe.md). * Trading is enabled once per currency (a standing `approve` to the pool). * For `USDC` orders signed with HMAC, **Real money trading** is turned on for the API key, and the event allows real money. Otherwise create returns `403 RealMoneyBetNotAllowed`. ## What is live | Feature | Phase one | | - | - | | `POST /api-keys/derive/` (wallet → HMAC keys) | Live | | `POST /orders/signing-context/` | Live | | `POST /orders/` with a signed intent, `gtc` and `ioc` | Live | | Cancel, batch cancel, cancel all | Live | | Order book, events, markets, wagers, balances | Live | | Safe registration, relay, enable trading | Live | | Collateral settlement on-chain at match | Live, asynchronous | | Resolution payout Pool → Safe | Live, automatic | | Pusher websockets | Live. `[PLACEHOLDER: Pusher app key and cluster for the preview host]` | ## What is not live | Feature | Status | | - | - | | Market orders (`price: null`) in `OOM` or `USDC` | Cannot be signed. Use `time_in_force: "ioc"` with a price | | `shares: "max"` in `OOM` or `USDC` | Do not rely on it. The signed `sharesRaw` must equal the resolved quantity, so send explicit shares | | `POST /orders/batch/` and `POST /orders/batch-update/` in `OOM` or `USDC` | Not the supported path. Each item needs its own signed intent, and a host that does not read intent fields on batch items rejects them. Loop over `POST /orders/` | | `GET /orders/{id}/` | Does not exist. Filter `GET /orders/` | | Fills or trades endpoint | Does not exist. Read fills from the order fields or the `order-update` websocket event | | Selling with `PATCH /wagers/{id}/` | Rejected for on-chain positions (`onchain_sell_requires_limit_order`). Place a signed `ask` | | Deposit endpoint for Safe balances | None. Transfer tokens to your Safe on-chain | | Withdrawing with an API key | Not available. A `USDC` withdrawal from the Safe goes through the relay with a wallet sign-in session. See [Safe wallet](https://docs.futuur.com/api-reference/me/safe.md#withdraw-from-the-safe) | | Withdrawing `OOM` | Not available | | ERC-1155 outcome tokens, split and merge | Not in phase one. Shares stay in the Futuur database | | Base mainnet | Not active | ## Next steps * [Get your API keys](https://docs.futuur.com/guides/get-api-keys.md) * [Place an on-chain order](https://docs.futuur.com/guides/on-chain-first-order.md) * [End-to-end Python bot](https://docs.futuur.com/guides/on-chain-bot-example.md) * [Errors](https://docs.futuur.com/errors.md) This documentation is built and hosted on [Mintlify](https://mintlify.com), a developer documentation platform.
