10% APY on your Bitcoin. Non-custodial.
Institutional yield strategies for serious BTC holders. Yield without surrendering control of your coins.

Yield options ask too much
Think existing Bitcoin yield products ask too much and deliver too little?
So did we.
Custodial products require handing over your Bitcoin. DeFi rates collapse when liquidity does. Until now, earning yield meant accepting trade-offs most serious holders wouldn't.
So what’s the alternative?

The answer is here
Non-custodial Bitcoin yield with Cobault.
You get the return upfront — 10% APY on the staked position. In exchange, your BTC upside is capped at 20% during the term. If Bitcoin rises beyond that, you keep your guaranteed yield, but not the additional upside.
It doesn’t matter if Bitcoin price goes up or down. You yield 10% APY either way.
Full control. Zero risk.
While staking, you and Cobalt share cryptographic control via multisig, governed by smart contract policy. Neither party can move funds unilaterally, eliminating counterparty custody risk.
