btcSOL

btcSOL is a Bitcoin-denominated liquid asset on Solana: users deposit SOL or liquid staking tokens into a contract and mint btcSOL at the prevailing rate, redeeming back into the original asset at the same rate. It targets users who want Bitcoin exposure while holding SOL and is developed by Zeus Network.

Mechanically, deposited SOL enters staking and restaking flows, and the resulting yield buys zBTC so that the unit of account behind btcSOL converges toward Bitcoin over time. The contract updates the conversion ratio from accumulated yield, giving earlier participants a lower ratio than later ones. Marinade's mSOL was the first liquid staking token integrated, letting users mint directly with it. Mainnet v1 went live on July 17, 2025 and was later folded into the unified Zeus App entry point. Redemption requests are processed in submission order, with queue length determining wait time.
