THORChain Reports $4B Swap Volume in Q4, Plans Solana and ZCash Integration

THORChain has completed its vault churn, marking a significant step in its recovery process following a security incident. **Key developments:** - The network successfully rotated to a new set of vaults after most were verified safe through the KeyVerify protocol - Funds are currently migrating from old vaults to new ones - Trading remains paused and will only resume once migration is complete and the network reactivates it The recovery involved implementing v3.19.0 with TSS security patches and a mechanism to quarantine compromised vaults. The network prioritized security throughout the extended recovery period.

THORChain has published a comprehensive post-mortem report detailing the May 15, 2026 security exploit. The report covers: - Complete timeline of the incident - How the protocol's security layers detected and responded to the breach - Technical analysis of the vulnerability - Proposed solutions outlined in ADR-028 The team has also released a two-part video analysis providing additional context on the exploit.

**Bridges don't actually move your assets** - they lock them in vaults and issue wrapped tokens as IOUs. When you bridge ETH to Solana, your real ETH sits locked while you receive a synthetic token representing a promise to unlock it later. **This architecture creates a critical vulnerability**: the system must maintain perfect synchronization between locked assets and minted synthetics. Major exploits include: - Wormhole: $320M lost - Ronin: $600M lost - Nomad: $190M lost **THORChain uses a different approach** with atomic swaps. When swapping ETH for SOL, your Ethereum enters a threshold-signature vault while native Solana from a separate vault goes to your address. No wrapped tokens exist. **Key differences**: - Bridge hack → your wrapped tokens become worthless - Atomic swap → transaction either completes or refunds, no synthetic tokens at risk **The tradeoff**: Native swaps are slower and more expensive than bridges, but eliminate the failure mode where users discover their wrapped tokens have no backing. With atomic swaps, you never hold someone else's promise.

**THORChain v3.14.0** addresses several critical issues affecting user experience and network operations. **Key Fixes:** - **Swap Speed Restored**: Fixed bug causing trade assets (BTC~BTC) and secured assets to take ~13 minutes instead of instant settlement - **Vault Recovery**: Automated retry system for failed refunds from retired vaults, eliminating manual intervention - **Quote Consistency**: Removed randomness in quote queries to ensure same inputs always return identical results - **Outbound Safety**: All transactions now checkpointed immediately to prevent silent failures **Technical Improvements:** - Retired vault balances automatically recovered and refunded - Streaming swap time estimates now accurate for rapid swaps - Enhanced node safety with automatic retry mechanisms These updates resolve operational overhead, improve swap reliability, and strengthen the overall network infrastructure for cross-chain liquidity.
