Liquid Yield Bearing Bitcoin
on Solana

zenBTC was developed by Zenrock Labs, an incubated business of 50T Fund, the largest crypto-only growth equity fund in the world managing over $2 billion in AUM across five funds. Zenrock is led by co-founders Jack Krevitt and Adi Dave, who leverage the fund's deep resources and connectivity to bridge the gap between DeFi and TradFi markets.

50T Funds was founded by Dan Tapiero, one of the most respected macro investors and entrepreneurs of his generation. Dan is a leader in digital assets, whose strategic vision and institutional network give Zenrock a unique edge in bringing institutional-grade crypto infrastructure to market.

The biggest wrapped Bitcoin products, wBTC and cbBTC, both rely on centralized custody. wBTC is custodied by BitGo, meaning a single company holds the keys to billions in Bitcoin. cbBTC is custodied by Coinbase. In both cases, you're trusting one entity with all of the BTC: the exact opposite of how blockchains were designed to operate.

zenBTC takes a fundamentally different approach. Private keys are cryptographically split across a network of independent node operators using distributed Multi-Party Computation (dMPC), with each fragment running inside a hardware-isolated secure enclave. The full key is never assembled. Transactions are signed collaboratively without any single party, including Zenrock, ever having access to the underlying Bitcoin. No single point of failure. No custodian to trust. No keys to steal.

zenBTC yield comes from real protocol fees on the Zenrock network, not token emissions or opaque hedge fund style trading strategies. Specifically, 5% of all zrChain network fees and 35% of zenBTC custody fees flow directly to zenBTC holders. The yield rate is self-balancing: as Zenrock earns more fees, yield rises; as more users mint to capture it, supply increases and yield normalizes. No governance votes, no manual adjustments. zenBTC is the only yield-bearing BTC that pays in actual sats. Not points, not governance tokens. Just Bitcoin paid out daily.

Minting zenBTC is quick and easy. First start by connecting any Solana wallet and creating a deposit address on the mint page. Then simply send BTC on the Bitcoin blockchain to your deposit address. Mints require three block confirmations on the Bitcoin blockchain and take 1 hour to process on average though exact timing can vary.

To redeem, simply burn your zenBTC on the redeem page. You will then receive your underlying Bitcoin back after the redemption processes (approximately 7 days). Because yield accrues over time, you may receive more BTC than you originally deposited!

zenBTC is live across Solana's DeFi ecosystem including Kamino Finance (lending, automated yield strategies, Liquidity Vaults), Orca, Meteora, and more. It's designed as a composable primitive so you can deploy it actively while the underlying custody remains unchanged and fully backed.

Yes. Zenrock has undergone extensive audits by Informal Systems and Halborn. For the latest audit details, check Zenrock's official docs.

$ROCK is the native token of zrChain, the Layer 1 that powers zenBTC's custody. All protocol fees from zenBTC, Hush, and any future products built on zrChain (Zenrock Labs and otherwise) flow through $ROCK tokenomics driving protocol level buy pressure on $ROCK.

$ROCK is a fixed supply asset of 1 billion with no inflation. Staking $ROCK earns a share of protocol revenue as well as baseline yield which decreases over time. The more zenBTC is used, the more value flows to $ROCK holders. For more details, check Zenrock's official docs.

Every product built on zrChain generates fees. A portion of all of those fees flows to zenBTC as yield. zenBTC receives 5% of all zrChain network fees, meaning fees from Hush Protocol, zenZEC, and any future products built on the network directly boost zenBTC yield. The more products Zenrock ships, the more usage they generate, and the more products other teams develop on zrChain infrastructure, the higher the yield for zenBTC holders. It's a compounding flywheel: each new product doesn't just stand on its own. It makes zenBTC more attractive, driving more minting, generating more custody fees, benefiting $ROCK token holders and stakers.

You'll need Bitcoin to deposit and a Solana wallet. Full docs at docs.zenrocklabs.io.
