Critical Alert
NOWCollateral 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.
Pure, native Bitcoin.
Zero bridges. Zero wrappers. 100% Layer 1 Bitcoin. Collateralize your BTC without exposure to wrapped tokens, bridge exploits or smart contract risks.
Verify everything on-chain.
Don't just trust our interface. Track your collateral on-chain in real-time.
Rehypothecation? Impossible.
Your collateral cannot be lent out, leveraged, or moved. It's not just our "promise" — it's literally written in code.
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.
No Origination Fees. No Hidden Costs.
Stop losing 1-2% to "admin fees".
Our rates are all in. Stop losing 1-2% to "origination" or "admin" fees — the rate you see is the rate you pay.
Between Lygos' lower interest rate and no origination fees policy, you can save $45,000+ on a $1M loan over the course of a year.

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%): This is an informational alert only, not a margin call. If your LTV approaches 80%, you'll receive notifications, but there is no mandatory action required.
- 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.
No. Unlike competitors who simply claim they don't rehypothecate, Lygos's non-rehypothecation is cryptographically enforced. Your Bitcoin is locked in a DLC on the Bitcoin blockchain, not held in a custodial wallet that could be used for other purposes. Neither Lygos, the lender, nor any other party can access, trade, lend, or otherwise use your collateral while your loan is active. This isn't a policy promise—it's a technical reality enforced by the Bitcoin protocol.
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.
Certainty, Engineered
Stop choosing between security and liquidity. With Lygos, you get both.
