Don't trust. Verify. Here's how.
Every claim we make about your collateral can be checked without asking our permission — on the Bitcoin blockchain, in open-source code, and in a public specification a decade in the making.
Three claims, three ways to check us.
Don't take our word for any of this — each claim is checkable on-chain, in the math, or in the code.
Your Bitcoin never leaves the chain.
Your collateral is a native Bitcoin DLC on Layer 1 — not an entry in our database. Paste your contract's address into any block explorer and watch it sit there, untouched, for the life of your loan.

Every outcome is signed before you lock a single satoshi. Nothing can be improvised later.
Every outcome is signed before you commit.
Repay, default, or liquidation — all three transactions exist, cryptographically signed, before your BTC moves. Neither Lygos nor the lender can invent a fourth outcome. The rules are enforced by Bitcoin, not by a company's promise.
Check your outcomes with our DLC Verify toolThe code securing your loan is public.
DLCs were designed in public, specified in public, and implemented in public — the code is here, every line readable. The ones marked Used by Lygos secure your collateral today.
One open spec, many interoperable implementations.
Every implementation above targets the same open standard. Started by Nadav Kohen and the Suredbits team in December 2019, the DLC Specification defines how clients interact, how the protocol works, and how signatures are generated — all in the open, all reviewable.

This code didn't appear overnight.
A global community of cryptographers and Bitcoin developers built DLCs in the open over a decade. A few of the people whose work Lygos stands on — see the full contributor list on GitHub.
Verifiable Bitcoin credit, built in the open.
Collateral locks on-chain in a DLC you can audit at any moment — starting at 10% APR with $0 origination fees.
