What Traders Pay
The schedule fixes the gas assigned to individual exchange messages, rather than imposing one identical fee on every transaction. Injective’s developer reference lists 180,000 gas for a spot market order and 190,000 for a derivative market order. Its suggested single-message transaction budgets add a 120,000-gas allowance for preliminary checks, including signature verification.
Gas Budgets for Common Exchange Operations
Source: Injective developer documentation. Suggested budgets assume one message and include a 120,000-gas allowance for preliminary checks; gas units are not $INJ fees.
At the current base gas price, those suggested budgets imply fees of **0.000048 $INJ for a spot market order** and **0.0000496 $INJ for a derivative market order**, calculated using Injective’s fee formula. These are budget-based examples, not a universal charge: the submitted gas limit and gas price determine the transaction fee.
Previously, gas was metered from computational work such as reads and writes to chain storage. Two successful single-message spot market orders from the same wallet and market, recorded in the minute before activation, paid approximately 0.0000195 $INJ and 0.0000553 $INJ. Those individual examples illustrate the prior variation, not an average fee or an across-the-board saving from the change.
The published schedule covers spot, derivative and binary-options order messages, along with deposits, withdrawals, transfers and position-margin adjustments. Injective’s announcement also highlighted perpetual trades and real-world-asset markets. The relevant distinction is the operation used: fixed gas applies to supported exchange messages, not automatically to every transaction involving a tokenized asset. Batch-order gas still scales with the number and type of orders.
IIP-709 changed only the fixed-gas switch. The proposal explicitly left all other exchange parameters unchanged, including the separate trading-fee settings.
