- THORChain v3.21 Update to Restore Solana and Zcash Trading After Exploit Fix — this brief
The upcoming THORChain v3.21 upgrade, scheduled for activation at block height 28,366,100 on October 23, 2026, aims to restore trading functionality for 
Solana (SOL) and 
Zcash (ZEC) after technical issues caused their suspension.
The update primarily addresses a critical exploit found in the Rujira Network's FIN contract, which posed a significant security risk to the protocol. Additionally, it resolves underlying technical flaws that had disrupted trading for SOL and ZEC.
Alongside the security fixes, THORChain v3.21 introduces the Streaming Yield feature, designed to enhance returns for bond providers within the ecosystem. However, the implementation of native 
Monero (XMR) support has been postponed to a future update.
According to DeFiLlama, THORChain's yield TVL currently stands at $137.68M, marking a 6.1% decrease over the past week. This suggests potential market uncertainty or shifting dynamics within the protocol's ecosystem.
In the broader market context, the total crypto market cap is $2.81T, with 
Bitcoin (BTC) up 1.29% in the last 24 hours. Solana and Zcash have seen positive price movements, with SOL at $104.52 (+3.18% 24h) and ZEC at $1124.61 (+5.42% 24h).
Since this brief published about 2 hours ago, Solana (SOL) has moved from ₹9,948.73$104.52 to ₹9,952.53$104.56 — +0.04%.
The chart plots SOL's price: grey is the move before this brief published, the vertical dashed line marks the moment it published, the horizontal dashed line is the price then, and the coloured area is the move since — from Token Times's market data (daily resolution). It shows what happened after the news, not that the news caused it; many factors move prices. Not financial advice.
At today's peer-to-peer rate, 1 SOL ≈ ₹10,850.19 (about $104.56), up 2.5% over 24 hours. The rupee itself trades about 9.0% above the official rate on the P2P market, so a Indian buyer's effective cost differs from the headline dollar price.
