Injective (INJ) is the native cryptocurrency of Injective, a proof-of-stake blockchain built for trading and other financial applications. INJ pays transaction fees, is staked to secure the network, and is used to vote on changes to the protocol. A share of the fees earned by applications on the chain is used each week to buy and destroy INJ, which makes the token's supply shrink when activity is high.
The Injective blockchain is built with the Cosmos SDK, the same toolkit behind Cosmos (ATOM), and connects to other Cosmos chains. Unlike most general-purpose networks, it ships ready-made financial building blocks, including a shared exchange engine, so developers can launch markets without writing their own trading code.
Injective in plain terms
Most blockchains are like an empty plot of land: anyone can build there, but each builder has to lay their own foundations. Injective is more like a ready-built marketplace with stalls, scales and a cash desk already in place. A team that wants to open a trading app moves into a stall and starts serving customers, using the market's shared order books and price feeds rather than building them from scratch.
INJ is the market's house currency. Traders use it to pay small fees, and people who lock it up help keep the marketplace honest and earn a reward for doing so. Each week, part of the rent collected from the stalls is pooled and auctioned off for INJ, and the INJ paid in that auction is destroyed. When the market is busy, more INJ disappears.
History
Injective Labs was founded in 2018 by Eric Chen and Albert Chon and was part of the first incubation programme run by Binance Labs. INJ was first sold to the public on the Binance Launchpad in October 2020. The network's mainnet launched in stages during 2021, starting with a "canary" chain with deposit limits before the full chain went live. A 2023 upgrade known as INJ 2.0 let any application on the chain contribute fees to the weekly burn, and in April 2024 holders approved INJ 3.0, which tightened the limits on new issuance. In November 2025 Injective added a native Ethereum Virtual Machine, so applications written for Ethereum can run on the chain alongside its original smart contracts. In January 2026 a governance proposal called the INJ Supply Squeeze passed with more than 99 percent support, further cutting issuance and expanding buybacks.
How it works
Injective uses a Tendermint-style consensus engine in which validators stake INJ, propose blocks and vote on them, reaching final confirmation in about a second. Holders who do not run a validator can delegate their INJ and share in rewards; see staking. Its best-known feature is an on-chain order book: buy and sell orders from many applications are matched by the chain itself in batches, a design meant to reduce front-running by bots that see orders before they are filled. Applications built on this engine offer spot trading, perpetual futures and other derivatives, as well as markets that track stocks, commodities and other real-world assets.
Supply and the burn auction
INJ started with a supply of 100 million tokens. New INJ is minted as staking rewards at a rate that rises when too little of the supply is staked and falls when more is staked, within upper and lower bounds set by governance. Working against that issuance is the weekly burn auction. A large share of the trading fees collected by applications on Injective, set at 60 percent of exchange fees, is placed in a basket. Bidders offer INJ for the basket, the highest bidder wins it, and the winning INJ is burned. A separate monthly community buyback lets holders commit INJ that is used to buy and burn tokens. Whether the supply shrinks in a given year therefore depends on trading activity: when fee income is high the burn can exceed new issuance, giving the token deflationary tokenomics, and when it is low the supply grows.
Uses
- Fees and staking. Transactions on Injective are paid in INJ, and staked INJ secures the network.
- Governance. Staked INJ is used to vote on upgrades, new markets and changes to issuance, as shown by the INJ 3.0 and Supply Squeeze votes.
- Collateral and trading. INJ is used as margin and traded on decentralized exchanges built on the chain, as well as on major centralized exchanges.
- Investment products. In 2025 fund managers including 21Shares and Canary Capital filed with the US Securities and Exchange Commission to list exchange-traded funds holding INJ.
Criticism and risks
The burn mechanism ties the token's supply to trading volume on a relatively small set of applications, so a drop in activity weakens one of INJ's main selling points. Markets for derivatives and tokenized stocks also raise questions of regulation, since in many countries offering such products requires a licence. Critics also point to the share of supply allocated to the team, early investors and the ecosystem fund, and to competition from other chains aimed at trading, which offer similar order-book features. Like other smaller-cap tokens, INJ has been far more volatile than Bitcoin (BTC).
