Most BTC wrappers like WBTC rely on custodians and opaque minting logic.
Coffer doesn’t. It exposes BTC to strategy layers with verifiable custody, enforced risk & modular yield; not liquidity black holes.
Self-custody stays intact. Execution stays transparent.
Reward doesn’t come without risk. Your custody is important. Coffer provides low-risk DeFi opportunities for large holders of BTC.
Coffer lets you define the risk you’re willing to accept; and enforces it at the infrastructure level, not just the interface.
You can’t manage risk if you don’t know where your capital lives.
With Coffer, your BTC stays in self-custody; in native vaults, earning across chains without ever leaving Bitcoin.
Real returns start with real control.
DeFi yields can be volatile; Coffer doesn’t gamble your Bitcoin.
It routes capital into strategies with risk parameters, enforced limits and preserved custody.
You stay in control; the guardrails stay on.
In Coffer’s architecture, Bitcoin is the backend; the capital anchor.
EVM chains and L2s are execution frontends for strategies.
Your BTC stays in a native vault; yield flows through the interfaces you choose.
CoBTC lets you access yield opportunities across EVM-compatible chains and L2s; no fragmented wallets, no bridging risks.
A single BTC-backed asset, governed by one key you control.
DeFi yield shifts fast; protocol by protocol, quarter by quarter.
Coffer keeps your BTC exposure aligned without chasing APYs, moving funds or giving up custody.
Yield moves; strategies evolve.
CoBTC is an ERC-20 it follows the best opportunities across EVM-compatible chains.
Your Bitcoin stays exactly where it belongs, in a native self-custodial vault you control.
Great infrastructure doesn’t demand attention; it just works.
Coffer stays behind the scenes; no custody friction, no execution drag.
Bitcoin doing more, reliably and on your terms.
Bitcoin is the most secure, liquid, and trusted asset in crypto; but mostly idle.
Coffer unlocks its full potential as collateral by connecting BTC to DeFi systems that respect self-custody, enforce risk, and deliver yield; without moving the Bitcoin.
You don’t modify Bitcoin; you build around it.
Coffer doesn’t wrap Bitcoin in complexity.
It adds programmable, modular layers on top; extending what Bitcoin can do without changing what it is.
Bitcoin doesn’t need new chains; it needs better interfaces.
Coffer builds those; turning cold BTC into programmable, yield-ready capital without touching the keys or the chain.
Custody stays intact; Bitcoin’s base layer remains untouched.
Most BTC is idle. Most DeFi ignores native Bitcoin.
Most infra breaks custody & large BTC holders do not want to give this up.
Coffer fixes all three🪄
- Native multi-sig smart accounts
- Yield access without leaving Bitcoin
- Institutional-grade custody logic
Back from a successful trip to .@TheBitcoinConf where we met face-to-face with miners, LPs, and builders from across the Bitcoin ecosystem.
The Coffer team has now mirrored over $300M in BTC on-chain as coBTC, with support from ViaBTC, F2Pool, and others. All BTC remains in cold storage under miner-controlled multisig; no custody is ever given up.
With coBTC live in production and already deployed through partners like @kernel_dao, @YieldNestFi & @loopfixyz, we are actively expanding integrations across EVM DeFi Protocols.
If you're building DeFi infrastructure, looking to grow TVL pre-TGE, or unlocking grant-based milestones — we can provide native BTC liquidity, already secured and ready to route.
