Bitcoin lender comparison
Compare Ledn's 12-month Bitcoin-backed loans with Stackit.ai's onchain BTC/ETH treasury workflow.
Last reviewed July 11, 2026 · Official sources linked below
Short answer
Ledn offers custodial Bitcoin-backed loans with a standard 50% initial LTV, fixed loan periods, and rates tiered by loan size. Stackit.ai is an onchain treasury-policy layer using variable Aave rates. Ledn fits a borrower who wants a serviced BTC-only loan; Stackit.ai fits an operator who wants BTC/ETH treasury rules and machine integrations.
This compares product structure, not just the lowest advertised APR. Rates, LTVs, eligibility, fees, and market parameters can change.
| Dimension | Stackit.ai | Ledn |
|---|---|---|
| What it is | A treasury policy and orchestration layer that uses third-party lending markets. The public product currently includes a self-serve sandbox and live market-rate reads; production access is assisted and the Base production API is marked in development. | A centralized Bitcoin financial-services company offering BTC-backed loans. |
| Borrow rate | The underlying Aave variable borrow rate is passed through and shown separately from Stackit.ai action fees. Live native-USDC rates are available for Base, Arbitrum, and Polygon. | APR is tiered by loan size and displayed in current product terms. |
| LTV and downside response | Rules are designed to monitor LTV and prepare or execute approved repayment actions as risk rises. Exact thresholds and execution depend on the approved policy, liquidity, oracle data, gas, and production availability; liquidation risk cannot be eliminated. | Generally 50% initial LTV, with current margin-call and liquidation levels published by Ledn. The borrower adds collateral or repays after warnings; collateral can be sold at the liquidation threshold. |
| Custody and control | Documented wallet-sovereign flows return unsigned transactions. Delegated automation requires revocable, policy-scoped permission; Stackit.ai says it does not hold private keys. | BTC collateral is held under Ledn's custody model; Ledn says loan collateral is not lent out. |
| Term | No separate fixed loan term in the public sandbox; the underlying onchain market determines the debt mechanics. | Typically a 12-month loan under current product materials. |
| Other costs | Aave interest plus published Stackit.ai per-action fees and network/protocol costs. Current fees are itemized in fees.json; protection and repayment actions carry no Stackit.ai fee, though gas and protocol costs can still apply. | APR plus a stated 0.50% trade spread in Ledn's LTV calculation documentation; confirm the final loan agreement and jurisdictional terms. |
About the alternative
Ledn's current product materials describe 12-month Bitcoin-backed loans funded in USD, USDC, or supported local currency, generally beginning at 50% LTV. Rates depend on loan size, and margin-call/liquidation thresholds apply as BTC price changes.
The key distinction
Stackit.ai is built around treasury actions and policies rather than a single BTC-collateral loan contract. It also exposes Aave rates and sandbox/API paths, but its production execution availability is more limited and assisted today.
Borrowers who want a Bitcoin-only, fixed-period loan with bank or stablecoin funding and established lender servicing.
Teams that want BTC and ETH treasury automation concepts, policy checks, and agent/API workflows built around onchain markets.
The reviewed Ledn loan material is focused on Bitcoin-backed loans. Stackit.ai's treasury positioning includes both BTC and ETH.
No. Ledn publishes its own loan rate tiers. Stackit.ai's current onchain rate layer uses Aave variable borrow rates.
Ledn has an active loan product subject to jurisdiction and eligibility. Stackit.ai's public sandbox and live rate reads are available, while production API access is currently assisted/in development.
Competitor facts come from official product or protocol documentation. Stackit.ai facts come from its public docs, endpoints, and current availability switch. Marketing rates are not treated as guaranteed offers. Review your personalized terms before borrowing.
Educational comparison only; not financial, legal, tax, or investment advice. Crypto-backed loans can lose collateral through liquidation, smart-contract failure, oracle error, market gaps, custody failure, or other execution risks.
Start with live protocol rates, add every fee, then test how your LTV behaves before you choose a borrowing path.
