Bitcoin moves closer to direct access to Zcash
The integration brings together two networks that share several characteristics while taking different approaches to privacy. Bitcoin retains a largely transparent blockchain. Zcash, by contrast, allows users to make shielded transactions using zero-knowledge proofs. BrefCrypto previously examined how far Zcash could realistically challenge Bitcoin on this front.
THORChain is now adding a potential bridge between the two.
The protocol has been working on Zcash’s native integration since March. Its v3.16 upgrade added specific support for ZEC UTXOs, the RPC calls needed to track its blockchain and an oracle allowing the protocol to obtain its price. Development continued through the adaptation to Zcash’s recent Ironwood upgrade.
On October 2, a THORChain node rotation finally enabled the entire network to begin monitoring Zcash. The ZEC pool is now active.
But the swaps are not live yet.
THORChain also warns that liquidity remains low. Large trades could therefore face significant slippage once trading is enabled.
No wrapped BTC or conventional bridge
THORChain’s technical appeal lies in its cross-chain design.
On many DeFi protocols, using bitcoin on another blockchain first requires representing it as a wrapped token. Users are then no longer handling native BTC directly. THORChain instead aims to enable swaps between the native assets of multiple networks, without requiring users to go through a bridge manually. Its interface already supports this type of operation between Bitcoin and several supported blockchains.
This architecture has already been used to move BTC in far less ordinary circumstances. BrefCrypto recently reported that 97.09 BTC stolen during a wave of attacks on Coldcard users had passed through THORChain before being routed through CoinJoin.
With Zcash, the privacy question becomes even more sensitive.
THORChain itself remains transparent: its vault inputs, outputs, swaps and addresses are publicly visible on-chain. The protocol also explains that its validators cannot simply select and censor an individual swap.
A future BTC→ZEC conversion could nevertheless give users the option of subsequently using Zcash’s native privacy features.
U.Today is moving faster than THORChain
This is precisely where U.Today’s headline becomes problematic.
The publication already describes THORChain as the first platform to enable direct, permissionless swaps between Bitcoin and Zcash, even suggesting access to Zcash’s shielded pools.
THORChain’s public announcement is more cautious: the pool is active; trading comes next. At this stage, it also does not confirm that future swaps will be able to send ZEC directly to a shielded address. Several publications that reviewed the announcement have reached the same conclusion.
That distinction does not diminish the significance of the launch.
Zcash is currently going through a period of strong growth. BrefCrypto reported in early September that ZEC had surpassed $1,000 as its ETF and mining activity advanced. Its arrival on THORChain could provide a new liquidity channel natively connected to Bitcoin, without relying on a centralized exchange.
The decisive step now remains: actually opening trading.
At that point, BTC holders could potentially move directly into ZEC using native assets on both sides. That would represent a significant integration for the privacy-focused cryptocurrency.
But as of October 3, THORChain has not yet pressed that button.
