Key highlights:
- INJ price plunged after Injective paused block production for nearly 4 hours
- The halt followed an exploit targeting its binary-options mechanism, with attackers reportedly extracting about $4.9 million
- Injective resumed block production with no rollback reported
Injective’s INJ token came under major selling pressure after the Injective mainnet halted block production for almost four hours in the wake of an exploit that allegedly drained $4.8 million. The incident forced developers to roll out an emergency patch while raising concerns across Injective’s onchain financial infrastructure.
Injective mainnet stops producing blocks
According to onchain researcher Rarma and QuickNode’s network records, Injective stopped producing new blocks for 3 hours and 42 minutes on August 31. The blockchain stalled at block 181,027,006 before advancing to 181,027,007 after an emergency patch was deployed with no rollbacks.

The halt came on the heels of an attack targeting Injective’s insurance fund and permissionless binary-options market mechanism. According to an analysis, the attacker carried out 299 operations and parked 1,999 ETH ($4.88 million) in a single Ethereum address.
An unofficial postmortem indicates the attacker exploited a vulnerability involving a disabled but still-registered Frontrunner oracle. With its underlying data sources removed, the oracle could be referenced when creating binary-options markets.
The bad actor created hundreds of markets pointing to the compromised oracle and triggered a mechanism designed to refund traders when no valid price was available. Per analysts, the mechanism awarded compensation at 2x, allowing the attacker to extract funds multiple times.
The latest exploit comes less than two months after a separate supply-chain attack compromised an Injective developer package and attempted to harvest users’ private keys. A bird’s-eye view indicates a surge in hacking incidents among crypto projects in 2026, with Ethereum and Solana recording the most losses.
INJ price reacts to security shock
The combination of a lengthy consensus halt and a near-$5 million exploit has put additional pressure on INJ, as traders reassess the security risks surrounding the network. INJ price fell by 4% hours after the incident to trade at $4.84 after weeks of heavy sideways trading.
Meanwhile, the incident also prompted exchange-level precautions. Bitget announced a suspension of INJ deposits and withdrawals due to wallet maintenance, with resumption time to be announced.
Zooming out, Injective has made keen progress, with the latest being an SEC registration as a Transfer Agent. The move made Injective the “first layer-21 blockchain” to obtain the status from the SEC, allowing it to maintain official records showing the ownership of a particular token.
While a US-based spot Injective ETF is still awaiting approval from the SEC, 21Shares has launched its physical staked Injective product in Europe. Pundits tip a US launch as a key catalyst for INJ price in the future as altcoin investors scan the horizon for a market rally.
