Bitcoin lender comparison
Compare Unchained's multisig Bitcoin-backed business loans with Stackit.ai's onchain treasury and agent workflow.
Last reviewed July 11, 2026 · Official sources linked below
Short answer
Unchained offers large Bitcoin-backed business loans using a collaborative multisig custody model where the borrower holds a key. Stackit.ai is a BTC/ETH treasury-policy layer using onchain lending rails and machine integrations. Unchained fits a U.S. business seeking a large, serviced BTC loan; Stackit.ai fits a team building recurring treasury automation and onchain monitoring.
Liquidation protection
Stackit.ai is not a fixed one-size-fits-all loan. Compared with using Unchained, you define the treasury policy: the point where protection begins, the conditions for repaying debt, and the conditions for taking profit or routing part of it to the loan. Stackit.ai monitors the approved rules and prepares or executes the permitted actions.
Unchained on its own
Stackit.ai automation
Set a Protection Point before the underlying liquidation boundary and choose the safer LTV area you want the position returned to when risk rises.
Define the market, LTV, deposit-consistency, or scheduled conditions that permit a repayment—and the maximum amount the policy may use.
Define the recovery or price conditions for taking profit instead of leaving every gain exposed through the next market move.
Choose whether an approved share of realized profit pays down principal. Less outstanding debt can reduce both interest exposure and liquidation risk.
Delegated automation is permission-scoped and revocable. Without active execution permission, Stackit.ai can prepare the transaction and risk context for your signature.
Automation is designed to reduce risk, not guarantee that liquidation or loss is impossible. Sudden market gaps, oracle problems, network congestion, insufficient liquidity, smart-contract failure, missing permissions, or failed execution can prevent an action from completing in time. Current live onboarding is assisted, and not every described automation is self-serve today.
This compares product structure, not just the lowest advertised APR. Rates, LTVs, eligibility, fees, and market parameters can change.
| Dimension | Stackit.ai | Unchained |
|---|---|---|
| What it is | A treasury policy and orchestration layer that uses third-party lending markets. You choose when to protect the position, repay debt, and take profits; Stackit.ai monitors the approved policy and prepares or executes the permitted actions. 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 Bitcoin financial-services company offering business loans secured by BTC. |
| 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. | A quoted fixed loan rate/APR shown by Unchained for the available business product.[source ↗] |
| LTV and downside response | You choose the Protection Point, safer LTV target, repayment conditions, and when profit-taking rules may pay down debt. Stackit.ai monitors LTV and prepares or executes approved actions as risk rises or profit conditions are met. Exact execution depends on the policy, permissions, liquidity, oracle data, gas, and production availability; liquidation risk cannot be eliminated. | Loan-specific starting LTV and thresholds are defined in the borrower's agreement. Margin-call and liquidation provisions apply; the borrower manages the loan with Unchained's servicing team.[source ↗] |
| 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. | Collaborative multisig model in which the borrower holds one key; Unchained says collateral is not rehypothecated. |
| Term | No separate fixed loan term in the public sandbox; the underlying onchain market determines the debt mechanics. | Current public materials describe a fixed payment/term structure. |
| 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. | Quoted interest/APR and agreement-specific fees. The public page currently targets loans of at least $150,000. |
About the alternative
Unchained's current loan page targets U.S. business entities, with a $150,000 minimum, a fixed term, and a collaborative custody structure. Its comparison material emphasizes no rehypothecation and borrower participation in multisig key control.
The key distinction
Stackit.ai aims at smaller, repeatable treasury actions and agent/API operation rather than a large manually originated business loan. Its rate is tied to the underlying onchain market instead of a quoted lender APR.
Eligible U.S. businesses needing a large Bitcoin-backed loan and prioritizing collaborative multisig custody and human loan servicing.
Businesses and autonomous agents that want recurring BTC/ETH treasury policies, live protocol rates, and API/MCP integration.
The reviewed current loan page is specifically for eligible U.S. business entities. Availability can change, so verify directly with Unchained.
Unchained describes collaborative multisig custody where the borrower holds one key and the collateral is not rehypothecated.
Stackit.ai explicitly publishes REST, MCP, x402, OpenAPI, and sandbox interfaces. Unchained's reviewed loan experience is a serviced business lending product.
The user chooses the Protection Point, safer target LTV, repayment conditions, profit-taking conditions, permitted amounts, and approved funding sources. Stackit.ai monitors those rules and can prepare or execute permitted actions according to the active permission model. Automation reduces risk but cannot guarantee against liquidation, loss, or failed execution.

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.
