Injective's mainnet stopped producing blocks for about four hours and 24 minutes on the evening of Nov. 9, disrupting deposits and withdrawals of the INJ token at several major trading platforms less than three days after a staking-focused INJ exchange-traded fund began trading on Nasdaq.
The chain halted at block height 191,016,661, whose timestamp was 21:04 Beijing time, according to Injective's node-monitoring data. Block production later resumed after validators deployed a patch, though public communications offered differing descriptions of why the network was paused.
Upbit, Coinone and Kraken separately announced temporary suspensions of INJ deposits and withdrawals while block production was interrupted. Each platform said spot trading remained available and indicated that transfer services would return once network stability had been confirmed.
The outage placed a practical constraint on token holders: an exchange can continue matching INJ trades internally while preventing on-chain settlement. Traders could buy or sell balances already held on those platforms, but could not reliably move INJ between self-custody wallets and exchange accounts until the chain resumed and platforms reopened their deposit systems.
Validators cited security patch and upgrade testing
Figment, a validator infrastructure provider, initially described the event on its Injective incident page as a coordinated mainnet pause requested by the Injective Foundation. The stated purpose was to guard against a potential attack path.
That description was later revised. Figment's page said a security patch was being tracked and prepared for deployment, and an update posted at 2:04 a.m. on Nov. 10 said validators had completed the patch and returned the network to normal operations.
A separate message relayed by an official administrator in Injective's Telegram community characterized the interruption as a scheduled upgrade test. According to that message, the network was testing emergency upgrade procedures as part of a readiness plan before a larger upgrade expected in the following weeks.
The two accounts point to a common operational outcome — validators paused the chain and later deployed software — while framing the trigger differently. A precautionary stop in response to a possible vulnerability carries a different operational implication from a pre-arranged test, particularly for users and platforms deciding when to resume transfers.
Injective had not produced blocks during the pause, meaning transactions could not receive new on-chain confirmations. For a proof-of-stake network, block production depends on validators reaching consensus and proposing new blocks. Halting that process can be used to prevent a suspected issue from spreading, but it also stops the normal movement of tokens and execution of applications relying on the chain.
Etf launch preceded interruption by days
The disruption came shortly after the launch of the staking-based INJ ETF, trading under the ticker INJC. On Nov. 6, Injective Labs Chief Executive Officer Eric Chen and Canary Capital Founder and Chief Executive Officer Steven McClurg appeared in Times Square to ring Nasdaq's opening bell for the product.
INJC was presented as a route for brokerage-account holders to gain INJ exposure, with staking yield intended to be reflected in the fund's net asset value. The structure gives share buyers exposure through a listed product rather than requiring them to hold tokens directly, operate a wallet or delegate tokens to validators.
A network pause does not necessarily stop an ETF from trading on Nasdaq. It can, though, complicate the process of calculating the economic value of an asset designed to incorporate staking rewards. If the underlying network is not producing blocks, the regular issuance and distribution of validator rewards may be interrupted for the duration of the halt.
The timing also put scrutiny on Injective's technical operations during a period when the project was presenting itself to traditional-finance audiences. YZi Labs posted public congratulations related to the Nasdaq bell-ringing around half an hour after the mainnet had already stopped producing blocks. Managing Partner Ella Zhang later posted a follow-up message.
Institutional plans had featured in recent updates
The network outage followed several project updates focused on institutional access and longer-term infrastructure goals. On Nov. 2, Injective introduced Institutional Rail, described as a direct connection channel between banks, trading firms, institutional applications and validators.
The project said the system would include predictable timing and pre-block receipts, which are records intended to provide information about transactions before they are finalized in a block. Such features target firms that need more certainty around transaction processing than a typical public-network interface may offer.
On Nov. 8, Injective published a five-year mainnet review that set targets including bringing $10 billion in real-world assets on-chain and developing quantum-resistant security technology. The review followed the ETF rollout and highlighted the network's attempt to position itself as infrastructure for tokenized financial products as well as decentralized trading applications.
The halt offered a more immediate test of the network's emergency processes. Coordinated validator action can limit the effects of a suspected security problem, but it also concentrates attention on how quickly operators communicate, deploy a fix and restore access for wallet users, applications and platforms.
Inj price showed limited immediate reaction
INJ traded within a relatively narrow range during the interruption, holding around $7.90 to $8.10 before and after the block-production stoppage, according to market records cited in the supplied materials. No abrupt sell-off was recorded during the downtime.
That price stability should not be read as evidence that the incident had no effect. The clearest impact fell on on-chain transfers: platforms paused deposits and withdrawals, while users sending funds during the disruption faced the risk of transactions waiting without confirmation until the network restarted.
Users moving INJ should confirm that deposits and withdrawals have been restored by their chosen platform before initiating a transfer. Exchanges often reopen such services only after their systems have observed stable block production and processed any transactions left pending during an interruption.
