Borrow against your Bitcoin or earn 12% on it — without surrendering custody. Non-custodial. No margin calls. No counterparty risk.
Listed & verified
Both parties commit Bitcoin. Both parties pre-sign every possible outcome. Bitcoin's base layer enforces the result.
You commit Bitcoin as collateral; the lender commits Bitcoin as principal. Both sit in the same Discreet Log Contract (DLC) pool on Bitcoin's base layer. Every settlement outcome is pre-signed by both parties before any Bitcoin moves. Cadena holds no key.
The contract gives you synthetic exposure to your locked collateral. You sell Bitcoin separately on your own exchange or OTC desk for the cash.
Cash in hand. Bitcoin position preserved through the locked collateral.
At maturity, the pre-signed Contract Execution Transaction broadcasts on-chain. The lender's USD target is paid in Bitcoin at maturity price. You receive the residual back to self-custody.
No margin calls. No active repayment.
Most Bitcoin lenders take your coins. We never touch them.
Your private keys never leave your hands. Bitcoin sits in on-chain DLC contracts — Cadena has zero ability to move, seize, or rehypothecate your collateral. The Signer App is open-source and verifiable.
Why non-custodial Bitcoin credit is structurally different from every other option.

An early Cadena contract settled on Bitcoin's mainnet. Every outcome was pre-signed.
Early contract — funded Nov 2025, settled May 2026
6-month term · $80k BTC · 12% annualized yield
Bitcoin's price fell over the term — the lender received more sats than the opening BTC contribution implied, exactly as the pre-signed CETs were structured to deliver.
The questions every prospect asks before their first contract.
If you're managing a Bitcoin treasury, running a fund, operating a mining business, or sitting on a sec-lending desk — Cadena's architecture maps onto your existing collateral and settlement mental model.
