OptiFi : Error on Solana costs $661,000 lost forever

Decentralized crypto-exchange OptiFi mistakenly permanently disabled its main network on solana, forever losing access to $661,000 in USDC stablecoins.

95% of the lost belonged to a member of the OptiFi team

Handling DeFi protocols requires caution and expertise. A mistake is still possible, in addition to unforeseen side effects as some fear in the context of the migration to the new version of Ethereum.

OptiFi is not affected by the upcoming ETH network merger, however. It is indeed a protocol built on the Solana blockchain. Its developers will nevertheless be more vigilant in the future.

OptiFi is a decentralized exchange (DEX) specializing in leveraged crypto-derivatives trading.

In a post on Twitter, the Solana blockchain-based decentralized financial protocol (SOL) team confirmed the permanent shutdown of the main OptiFi network:

In other words, the program of the platform specializing in derivatives was indeed accidentally closed on the mainnet Solana. This episode resulted in a loss of $661,000 in stablecoin USDC, 95% of which belonged to a member of the OptiFi team. The protocol has already pledged to refund other affected users within 2 weeks.

OptiFi nevertheless apologizes and details the reasons that led to this loss. Thus, it is the update of the program’s code on Solana that led to this expensive failure.

This mistake and its media coverage could benefit other Solana developers in the future. OptiFi warns them and encourages them to handle the “solana program close” command with care.

The DeFi protocol also calls on Solana developers to include a warning message in the documentation and command line interface (CLI) to help developers understand the offending function… and especially its risks. A weapon of mass destruction deserves a few warnings.
