A top-100 decentralized finance (DeFi) crypto project is recovering after enduring a 20-hour network outage due to a technical error this week.
THORChain (), a decentralized cross-chain liquidity protocol, announced on Thursday afternoon that its chain had halted.
On Friday morning, the project the network was operational again after a 20.5-hour outage.
THORChain developers said a full post-mortem will be released next week, but on Thursday evening, amid the outage, they briefly outlined on Twitter what caused the issue.
“Turns out to be string manipulation: code was pushing a cosmos.Uint (instead of a uint64) into a string, which causes the string to get the point of the big int instead of the actual value, causing the memo string to be different on different nodes.
Didn’t see this in stagenet because the bad memo never gets written to disk/block, because it gets swapped immediately. Where at mainnet has a queue and therefore the swap to synth doesn’t get executed the same block, and the bad memo is written to the block.”
The value of THORChain’s native asset, RUNE, wasn’t impacted much by the outage. The 90th-ranked crypto asset by market cap is up over 3% in the past 24 hours and is trading at $1.57 at time of writing.
