What a contract looks like
Each perpetual future is uniquely identified by a symbol (for example,BTCUSDT). Its contract specification includes:
| Field | Meaning |
|---|---|
| Symbol | On-chain identifier, usually BASEQUOTE |
| Contract multiplier | Number of base units represented by one contract (e.g. 1000PEPE = 1,000 PEPE per contract) |
| Tick size | Smallest allowable price increment |
| Lot size | Smallest allowable quantity increment |
| Minimum notional | Minimum order value required to place an order |
| Maximum order size | Largest quantity allowed in a single order |
| Max leverage (tier 1) | Highest leverage available at small position sizes |
| Mark/index components | The spot venues aggregated into the index price |
| Fee group | Determines maker/taker schedule (see Fees) |
| Funding parameters | Interest rate I, funding rate caps, premium smoothing |
| Liquidation parameters | Risk-limit tiers, maintenance margin rates |
| Trigger-protect | Deviation threshold that switches stop orders from last price to mark price |
Symbol conventions
Intention uses a suffix-based symbol convention, similar to major CEXs:BTCUSDT,ETHUSDT,SOLUSDT— standard USDT-denominated perpetualsBTCPERP,ETHPERP— alternative aliases for some majorsBTC-26DEC25,ETH-27MAR26— dated futures variants1000PEPEUSDT,1000000BABYDOGEUSDT— contracts with non-unit multipliers for small-denomination tokens
Tick size and lot size
Price ticks and quantity lots bound the grid on which orders can exist. Orders that do not conform to a symbol’s tick or lot size are rejected at intake. The matching engine rounds computed values (for example, Scale-order prices) toward the grid using the rules in Precision.Leverage tiers
Maximum leverage depends on position size. As your position grows, the risk-limit ladder steps down the allowed leverage and steps up the maintenance margin rate. See Leverage for the full specification and a worked example.Listing lifecycle
New contracts go through three phases:Pre-configuration
The risk team configures index components, fee group, leverage tiers, and funding caps at least 30 minutes before listing.
Pre-listing price generation
Starting at least 10 minutes before listing, the chain generates a stable index price for the symbol from external spot venues to validate data-source health.
Contract specifications can be queried directly from the chain or through the public REST API. The canonical source is always the on-chain listing record.
