Lendasat
24-Hour Capital Activation
Receive your funds directly to your bank account, as stablecoins, or on a VISA card in 24 hours or less. This rapid access contrasts sharply with traditional bank loans, which can take weeks for approval and disbursement, providing crucial liquidity when you need it most.
Non-Custodial & Bank-Grade Security
You never give up custody of your Bitcoin. Loans are secured via a MultiSig setup, a bank-grade security standard that ensures you remain in full control of your collateral throughout the entire loan term, eliminating counterparty risk.
Liquidation Protection with Alerts
The platform offers a safety buffer. For example, if you borrow $1,000 against $2,000 in Bitcoin, your collateral is protected until Bitcoin's value drops to $1,111. You receive proactive alerts before nearing this threshold and can add more Bitcoin to maintain your position. If liquidation occurs, the loan is repaid, and any remaining Bitcoin value is returned to you.
Zero-Bureaucracy Process
Access liquidity without traditional hurdles. There are no credit checks, no income verification, no paperwork, and no mandatory KYC. This streamlined, private process is designed for speed and user sovereignty, focusing solely on the value of your Bitcoin collateral.

Lendasat FAQ
How does Lendasat's liquidation protection work?
Lendasat provides a safety cushion. If you borrow $1,000 with $2,000 in Bitcoin collateral, your Bitcoin is protected until its value drops to $1,111. The system will send you alerts as you approach this threshold. You can add more Bitcoin to increase your safety margin. If the price falls below the threshold, the platform automatically repays your loan and returns any remaining Bitcoin value from the collateral to you.
What are the requirements to get a loan?
The primary requirement is owning Bitcoin to use as collateral. There is no credit check, no income verification, and no mandatory Know Your Customer (KYC) process. You simply need to lock Bitcoin worth more than the loan amount you wish to borrow, with a recommended collateral ratio of 2x the loan value.
In what forms can I receive my loan funds?
You can receive your loan instantly through multiple methods tailored to your preference. Options include direct bank transfer, receiving stablecoins like USDT or USDC (e.g., on the Polygon network), or having funds loaded onto a VISA card for immediate spending.
Is my Bitcoin safe while it's used as collateral?
Yes. Lendasat operates on a non-custodial model using MultiSig security. This means you never relinquish custody of your Bitcoin. You remain in full control of your private keys throughout the loan period, with the collateral held in a secure, shared wallet that requires multiple signatures for any transaction.
