Critical Alert

NOW

Collateral withdrawals are temporarily suspended.

Never, ever, see this again.

Custodial lenders work until they don't.

With Lygos, there's nothing to suspend. We never hold your Bitcoin.

Lygos: Stop trusting.
Start verifying.

Finally, Bitcoin credit that eliminates counterparty risk by design.
Every loan is secured by cryptography, that you can verify.

Non-custodial collateral.

Your Bitcoin is secured in a cryptographic contract you co-sign. Lygos or the lender never takes custody — and cannot move your BTC.

Rehypothecation? Constrained by design.

The DLC restricts collateral movement to pre-signed contract outcomes that can be verified on-chain.

Bankruptcy remote by design.

If Lygos or our lenders fail, your collateral isn't exposed. Simply repay your loan and reclaim your BTC.

All powered by math, not discretion.

Lygos uses Discreet Log Contracts (DLCs) to secure your BTC collateral —cryptographic agreements where all loan outcomes are defined in advance and enforced automatically on-chain.

“I bought a plane with Bitcoin — without selling any Bitcoin.”

Lygos let me make a cash offer on a 200mph Cessna, close fast, and negotiate a better price. And I didn't even have to sell a single sat.

“Lygos never holds my BTC.”

Keeping my bitcoin on a centralized platform never sat right with me. Lygos helped me refinance my loan out. The team walked me through everything and it felt very white glove.

It's locked in a non-custodial DLC I can verify myself.

Frequently Asked Questions

Get answers to common questions about our non-custodial architecture and DLC technology.

Non-custodial means you never hand over unilateral control of your Bitcoin to Lygos or any third party. Your collateral is locked in a Discreet Log Contract (DLC) on the Bitcoin blockchain—a programmable 2-of-2 arrangement where both you (the borrower) and the lender must cooperate to move funds.

Unlike custodial lenders who take possession of your Bitcoin and can rehypothecate or lose it (as happened with Celsius, BlockFi, and others), your collateral remains secured on-chain in a contract address that you co-sign. No single party—not Lygos, not the lender, not the oracle—can unilaterally access or move your Bitcoin.

Lygos offers the following LTV structure:

Initial LTV (50–70%): This is the loan-to-value ratio at origination. Most borrowers choose an LTV between 50–65%, providing a substantial cushion against price volatility.
At-Risk Threshold (80% LTV): This is an informational alert, not a mandatory margin call. You can review your position and choose whether to add collateral or make a partial repayment.
Liquidation LTV (90%): If your LTV reaches 90%, collateral may be liquidated to repay the loan. There is no mandatory margin call; liquidation is automatic at breach.

Lygos uses a non-custodial DLC structure designed to constrain rehypothecation. Your Bitcoin is locked in an on-chain contract with pre-signed outcomes instead of a platform-controlled custodial wallet, and the contract flow is verifiable on-chain.

Lygos offers loans ranging from $25,000 to $100,000,000. We focus on serving high-net-worth individuals, businesses, and institutions who need meaningful liquidity without selling their Bitcoin holdings.
