THORChain has fully resumed trading after more than five weeks offline, the decentralized cross-chain liquidity protocol announced on June 23, 2026. The restart follows a $10.7 million exploit on May 15 that drained one of its six Asgard vaults, forcing an immediate network-wide halt.
In a post on X, the protocol confirmed that signing, churning, liquidity provider actions, and swaps are all live again. “Every vault verified, every keyshare checked,” THORChain stated, emphasizing that security—not speed—guided the recovery process. The exploit, flagged by blockchain investigator ZachXBT and security firm PeckShield, stemmed from a weakness in the GG20 threshold signature scheme. A malicious node operator progressively leaked key material to reconstruct a full private key, draining one vault before automatic solvency checks caught the imbalance within minutes. The remaining five vaults were unaffected.
To resume operations, validators approved the v3.19.0 upgrade, which introduced compromised-vault quarantine, keyshare checks, and recovery logic tied to ADR028. Legacy vaults were migrated to a new vault set only after every keyshare was verified. The protocol initially faced community backlash for proposing to retain a patched version of GG20 rather than replacing it outright; the final recovery path patches the immediate flaw while longer-term cryptographic changes remain under review.
THORChain’s native token RUNE traded at $0.419456 on restart day, according to crypto.news market data. The price was down 0.2% over 24 hours but up 2% over the past week, with daily volume reaching $16.29 million. The token remains far below its all-time high but avoided a sharp selloff upon the restart.
Looking ahead, THORChain plans to launch native Monero (XMR) swaps, which are already working in end-to-end testing. Zcash (ZEC) support is expected to follow, along with dynamic fees and deeper liquidity upgrades. The restart gives the protocol a chance to rebuild trading activity, but operational stability and the return of liquidity will be the next key tests.
