Unknowingly issuing a command that stopped its mainnet software and rendered it unrecoverable, a decentralized cryptocurrency (D options exchange terminated its own life.

After trying to upgrade its platform’s code on Monday, OptiFi’s development team notified users that it had abruptly shut down. The software incident reportedly also locked up about 660,000 USD Coin (USDC) on-chain, according to the decentralized exchange.

While a significant portion of the locked-up USDC was apparently vested by one of its team members, OptiFi has promised to make up for any user cash lost as a result of the blunder. The business has also advised other Solana blockchain developers to be cautious of the effects of the “Solana program close” command.

The platform detailed the sequence of incidents that resulted in the unexpected shutdown of its mainnet. It started with a failed attempt to update the Solana program code.

Due to what the team claimed as a poor network state, the deployment took longer than usual, and the command was aborted. With that said, a buffer address was made to receive the SOL that the team wanted to recoup.

In the past, by quitting the software, the team was able to restore SOL from buffer accounts without the use of memory phrases. After running the command, the strategy appeared to have been successful at first because the team was able to recover the SOL and attempt to deploy the application again.

The application had been shut down and couldn’t be restarted without using a different program ID, according to an error message that was returned. The team’s worries that it wouldn’t be able to reload the software with its prior ID were validated after conversations with a Solana core engineer.

The Solana development community has been urged by the OptiFi team to investigate two-step confirmation when using the “Solana program close” function and to warn users of the consequences of using the command.
