Intention Exchange lists USDC-margined perpetual futures on crypto majors, mid-caps, and long-tail assets, plus pre-market contracts for newly launched tokens. Every market has a deterministic, on-chain specification — traders and integrators can fetch the full contract list and its parameters directly from the chain.

​
What a contract looks like

Each perpetual future is uniquely identified by a symbol (for example, BTCUSDT). Its contract specification includes: Unknown values for a specific listing are marked TBD by listing — each new contract is parameterized at list time by the risk team and can be updated by governance afterwards.

​
Symbol conventions

Intention uses a suffix-based symbol convention, similar to major CEXs:
  • BTCUSDT, ETHUSDT, SOLUSDT — standard USDT-denominated perpetuals
  • BTCPERP, ETHPERP — alternative aliases for some majors
  • BTC-26DEC25, ETH-27MAR26 — dated futures variants
  • 1000PEPEUSDT, 1000000BABYDOGEUSDT — contracts with non-unit multipliers for small-denomination tokens
A contract’s multiplier is baked into index-price calculation so that all downstream math (funding, margin, PnL) uses the contract-scale price, not the raw spot price.

​
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:
1

Pre-configuration

The risk team configures index components, fee group, leverage tiers, and funding caps at least 30 minutes before listing.
2

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.
3

Live trading

The contract opens for trading with the pre-validated index. Pre-market and Innovation-Zone contracts start in fee group 6 and automatically move to their target group after a review period.
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.
