THORChain shipped v3.20 on Aug. 24, adding an experimental Stable Reserve for 1:1 stablecoin swaps and two POL Mimirs governing protocol-owned liquidity.
The release, detailed in THORChain's protocol upgrade blog post, marks the first operational deployment of Protocol-Owned Liquidity controls since v3.18 laid the groundwork. The Stable Reserve lets eligible stablecoins trade directly against protocol-owned inventory instead of routing through RUNE-based pools, executing at 1:1 with no liquidity fee or slip when inventory is sufficient. Normal outbound network fees still apply, and the feature ships disabled by default with depeg protections built in.
Two POL Mimirs now give node operators direct control over how much System Income flows into protocol-owned liquidity and which pools are eligible to receive RUNE liquidity. The mechanism redirects a portion of THORChain's System Income into a dedicated reserve, then deploys that capital as RUNE liquidity into selected pools. The intended flywheel: deeper protocol-owned liquidity improves swap execution, attracts more volume, and generates additional System Income.
The upgrade also advances Monero and Zcash integrations. Monero receives fixes for FROST key generation, signing, recovery, vault rotation and solvency reporting, while Zcash support moves forward through compatibility with its NU6.3 Ironwood upgrade. Solana gains outbound recovery, fresher signing state and improved solvency reporting, with BNB and Base preparing to return progressively.
ERC-20 Memoless Swaps reduce wallet integration friction, and MOR joins Ethereum and Base token lists. On the security front, TSS keyshares are now encrypted at rest, validator seed handling is safer, and additional swap, refund and vault protections are included for node operators. Churn is set to resume, giving the network another operational reset after the $10.7 million exploit led to a month-long security review and trading halt.
The v3.20 release positions THORChain to compete more aggressively on stablecoin swap efficiency while giving node operators direct governance over liquidity deployment. The Stable Reserve's 1:1 execution model could draw stablecoin volume away from centralized exchanges and rival DEXs if testing supports gradual activation. The POL flywheel, if deployed effectively, could deepen liquidity across THORChain's pools and strengthen the RUNE token's role as the network's settlement asset.
