Bitcoin lender comparison
Compare SALT's fixed-term Bitcoin-backed loans with Stackit.ai's onchain treasury and variable-rate approach.
Last reviewed July 11, 2026 · Official sources linked below
Short answer
SALT offers fixed-rate, fixed-term Bitcoin-backed loans with published LTV tiers. Stackit.ai uses variable-rate onchain lending rails inside a broader treasury-policy workflow. SALT fits a borrower who wants a conventional BTC-secured cash loan with a known term and rate; Stackit.ai fits an operator building a recurring BTC/ETH treasury with rules and integrations.
This compares product structure, not just the lowest advertised APR. Rates, LTVs, eligibility, fees, and market parameters can change.
| Dimension | Stackit.ai | SALT Lending |
|---|---|---|
| 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-backed lender offering cash 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. | Published fixed APR by starting LTV and term; current offers remain subject to change and eligibility. |
| 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. | SALT currently publishes 30%, 50%, and 70% starting LTV options. Margin-call and stabilization thresholds apply; collateral can be sold if required actions are not taken. Optional SALT Shield eligibility may change the response. |
| 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 is held as collateral for the loan term under SALT's lending and custody arrangements. |
| Term | No separate fixed loan term in the public sandbox; the underlying onchain market determines the debt mechanics. | One-, three-, or five-year terms for lower LTV tiers; the 70% tier is currently one year. |
| 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. | Fixed APR. SALT's June 2026 pricing page says no origination fee or prepayment penalty for the described new loans; confirm final agreement terms. |
About the alternative
SALT publishes Bitcoin-backed loan tiers at 30%, 50%, and 70% starting LTV, with fixed rates and terms. Margin calls and collateral stabilization or sale can occur as LTV rises, although optional protection programs may apply to qualifying loans.
The key distinction
Stackit.ai's rate follows the underlying onchain Aave market rather than locking a multi-year lender APR. The product is designed around ongoing deposits, treasury rules, and LTV-management actions, not only originating a one-time cash loan.
Bitcoin holders who want a quoted fixed APR, a defined term, and lender-managed cash-loan servicing.
BTC/ETH treasury operators who accept variable protocol rates in exchange for a rules-oriented, API-accessible treasury workflow.
This page assumes the spoken name referred to SALT Lending. SALT is an established Bitcoin-backed lender; no lender named 'Assault' was identified in the reviewed comparison set.
SALT publishes fixed rates for defined terms. Stackit.ai's underlying Aave borrow rate is variable and can change with market utilization.
SALT's current official pricing describes a 70% starting-LTV tier for a one-year loan. Higher starting LTV means less buffer before risk thresholds.
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.
