Centralized lender comparison
Compare APX's regulated BTC/ETH loans with Stackit.ai's variable-rate onchain treasury workflow.
Last reviewed July 11, 2026 · Official sources linked below
Short answer
APX offers fixed-rate BTC/ETH-backed loans in the U.S. and Canada with terms from three to 60 months and up to 60% starting LTV. Stackit.ai is an onchain treasury-policy layer using Aave variable rates. APX fits borrowers prioritizing a regulated lender and long fixed terms; Stackit.ai fits recurring treasury and agent operations.
This compares product structure, not just the lowest advertised APR. Rates, LTVs, eligibility, fees, and market parameters can change.
| Dimension | Stackit.ai | APX 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, compliance-focused crypto-backed lender serving eligible U.S. and Canadian borrowers. |
| 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. | Fixed APR currently advertised from 9.99%, with final pricing based on the loan offer. |
| 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. | Borrowers choose 20% to 60% initial LTV; current public rules describe an 80% warning level and liquidation at 90%. Users can add BTC/ETH or repay at the soft margin call; APX may partially sell collateral to restore the original LTV at liquidation. |
| 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. | Segregated BitGo cold-storage wallets with onchain visibility, according to APX. |
| Term | No separate fixed loan term in the public sandbox; the underlying onchain market determines the debt mechanics. | Three to 60 months, extendable subject to current terms. |
| 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. | Interest, no currently advertised origination/admin fee, minimum-interest rules for early closure, and a 5% fee on liquidated collateral. |
About the alternative
APX currently advertises rates starting at 9.99% APR, no origination or admin fee, BTC/ETH collateral, and segregated BitGo custody. Its public rules describe an 80% soft margin call and automatic partial liquidation at 90% LTV with a processing fee.
The key distinction
APX provides a lender relationship, fixed term, fiat/USDC funding, and compliance servicing. Stackit.ai provides policy and automation interfaces around onchain markets, with more variable costs and more limited current production availability.
U.S. or Canadian borrowers who want fixed rates, long terms, segregated custody, and centralized customer support.
Treasury operators and agents who want Aave-based rates, machine interfaces, and rules for repeated BTC/ETH treasury actions.
APX describes itself as approved by Canadian securities regulators and serving eligible U.S. and Canadian borrowers. Exact legal entity and protections should be checked for the applicant's jurisdiction.
APX currently lists Bitcoin and Ethereum.
No. APX provides warnings and time to add collateral or repay, but its published rules allow automatic partial liquidation at 90% LTV.
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.
