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.
The code securing your loan is public.
DLCs were designed, specified, and implemented in the open, and the libraries Lygos runs on are public: every line is readable. The ones marked Used by Lygos secure your collateral today. Your contract itself stays private, a bilateral agreement between you and your lender. What's public is the code, not your terms.
You can recover your collateral without us.
Everything you need to get your Bitcoin back is fixed the moment your DLC is signed and funded — including settlement transactions already signed and waiting on Bitcoin.
Four steps — none of them need Lygos
Pay the exact amount to the lender-controlled, loan-specific address saved in your recovery pack.
The independent oracle confirms the repayment outcome under its published policy and releases a public signature.
The oracle attestation unlocks the already-signed Bitcoin transaction encoded at loan origination.
Anyone can submit the valid CET to Bitcoin. The collateral returns to the address fixed in the DLC.

Illustrative recovery flow — the exact repayment amount, addresses, and oracle policy are defined by your signed loan and DLC.
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.
Read the DLC specNone of this is new. A decade in the making.
Full lineage on the DLC specThis code didn't appear overnight.
DLCs are a community effort a decade in the making. These are some of the people whose work secures your loan.
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.
