Contract parameters - TrueCurrent Docs

Use the onchain DerivativeMarket response as the source of truth for production systems. Market parameters are set per-market and can change through Injective governance.

What governs a market

Every TrueCurrent perpetual market is an Injective derivative market. Its parameters live onchain and include:

Parameter	What it controls
Tick size	Smallest price increment a quote can use
Lot size	Smallest quantity increment per order
Min notional order size	Smallest dollar-equivalent order the market will accept
Initial margin rate (IMR)	Minimum margin to open a position; equal to `1 / max_leverage`
Maintenance margin rate (MMR)	Minimum margin to keep a position open; below this, liquidation triggers
Funding rate cap	Per-market clamp on the hourly funding rate
Max open interest	Cap on aggregate notional in the market
Settlement currency	The quote-side asset used for margin and settlement (USDC for current markets)
Oracle source	The Injective oracle feed used to derive mark price

To get the live values for a market, query Injective’s exchange module DerivativeMarket endpoint. Do not hard-code values in long-lived clients — re-read at startup, and refresh on governance events that touch your market.

How parameters are set

Contract parameters for an Injective derivative market are set when the market is first created via an Injective governance proposal. Subsequent changes also require a governance vote.

The process:

A governance proposal is submitted on the Injective chain specifying the parameter values

INJ stakers vote to approve or reject the proposal

If approved, the parameter update takes effect at the governance execution block

This means contract parameters can change over time. Always verify current values from the onchain source if you are building a quoting or risk system that depends on them.
