Injective proposes fixed gas fees to make DeFi trading costs predictable

Injective wants traders to know what a transaction will cost before they send it. The DeFi-focused Layer-1 blockchain is moving toward a governance proposal that would set fixed gas values for messages in its exchange module.

The feature is already running on Injective’s testnet. It still needs a governance vote before it reaches mainnet.

What the proposal actually changes

Today, the gas a transaction consumes depends on how much computation it requires. Gas is the unit that measures the work a blockchain does to process an action.

Injective’s proposal swaps the meter for a flat fare. Specific exchange actions would carry predefined gas amounts instead of floating with computational load.

The covered actions include order placements, cancellations, and subaccount transfers.

One concrete example: MsgCreateDerivativeLimitOrder, the message used to place a limit order on a derivatives market, would be fixed at 330,000 gas. A trader would know that number in advance, every time.

The design is meant to keep spam protections intact. Fixed pricing does not mean free pricing, so flooding the network with junk orders still carries a cost.

Injective’s minimum gas price sits at 160,000,000 INJ units. In practice, that works out to typical fees of about $0.0003 per transaction.

Already fast, now aiming for predictable

Injective reports average block times of roughly 600 to 650 milliseconds.

The network also reports throughput of 25,000 transactions per second. Finality comes through Tendermint, now known as CometBFT, the consensus engine used across much of the Cosmos ecosystem.

Injective is built on the Cosmos SDK and designed specifically for decentralized finance. It runs MEV-resistant frequent batch auctions, which group orders together to limit front-running by bots that try to jump ahead of other traders.

It also supports both EVM and WASM smart contracts.

How governance will decide

Injective’s protocol changes go through onchain governance. Holders of staked INJ tokens vote on parameter changes like this one.

The process includes deposit requirements to bring a proposal forward and set voting periods before a decision is final. Until stakers sign off, the fixed gas values stay on testnet.

What this means for traders and the wider DeFi landscape

The most direct beneficiaries would be high-frequency traders and market makers. These participants may submit and cancel huge numbers of orders, and variable gas makes their cost modeling harder.

A fixed gas schedule lets a trading firm treat transaction fees as a known line item.

Most blockchains price execution dynamically for good reason: it ties fees to the actual burden on the network. Injective’s approach narrows that flexibility for a specific set of well-understood exchange messages.

For traders already active on Injective, the near-term impact is modest in dollar terms, given fees already hover around $0.0003. The bigger shift is operational: one less variable to model before hitting submit.
