FAQs

What is Bitsri?

Bitsri (Bitcoin for Strategic Reserve & Investments) is a trustless, permissionless, decentralized, non-custodial platform that lets users borrow or earn USDC using their Bitcoin—without giving up custody, privacy, or control. It’s DeFi, reimagined for BTC.

Bitsri currently offers two powerful vaults:

  • Bitsri Lending Vault:
    Deposit BTC and borrow USDC at 70% Loan-to-Value (LTV) with a fixed 10% annual interest rate.
    ✅ No liquidation. ✅ No due dates. ✅ No restrictions.

  • Bitsri Yielding Vault:
    Deposit BTC and earn upto 10% APY in USDC. Profits are generated by the protocol using your BTC as collateral for strategic yield opportunities across trusted DeFi protocols.

With bitcoin-backed loans on Bitsri, you can borrow USDC by pledging your BTC as collateral. Your Bitcoin remains in our smart contract vault, while Bitsri facilitates a fixed-rate loan based on your collateral amount of upto 70% of Loan to Value Ratio.

Bitsri is built on audited smart contracts, uses zkSnarks, zkBridge, Chainlink, and Blockcypher APIs for trustless operations, and is entirely open-source.
Security, transparency, and decentralization are at the heart of our design.

No. 

    • No platform usage fees.

    • No Transaction Fees

    • The only cost is the Flat 10% interest rate (for borrowers).

LTV is the ratio of your loan amount to the current market value of your BTC.
Bitsri offers a fixed 70% LTV.
Example: If you deposit $10,000 in BTC, you can borrow up to $7,000 USDC.

⚠️ Bitsri Lending Vault is non-liquidating — even if BTC drops, your loan will never be forcibly closed or liquidated.

  • Lending Vault: Fixed 10% APR interest on the borrowed USDC.

  • Yielding Vault: Target APY is 10% USDC, distributed based on protocol earnings.

  • There are no floating or dynamic interest rates — Bitsri simplifies DeFi lending with predictable terms.

No. Bitsri is 100% non-custodial. Your Bitcoin is locked in smart contracts, never transferred, reinvested, or accessed by the team. You retain full ownership and visibility at all times.

No. Bitsri is a privacy-first DeFi protocol.
You don’t need to submit any personal data. Simply connect your wallet and interact with the smart contracts directly.

When you deposit BTC into the Yielding Vault, Bitsri uses that BTC as collateral to borrow stablecoins from DeFi protocols (like Aave, Spark, or MakerDAO).
The borrowed USDC is deployed into yield-generating strategies, and profits are shared with depositors.

Your BTC remains locked and never gets directly invested or moved.

Yes. You can:

  • Borrow USDC from the Lending Vault instantly, anytime.

  • Withdraw your BTC and earned USDC at any time from either vault (subject to vault liquidity).

  • Repay your loan fully or partially at your own pace—there are no minimum payments or due dates.

  • Bitsri’s Lending Vault is designed with no liquidation risk.
    Unlike traditional lending platforms, your BTC will not be liquidated if the price drops. You’re free to repay or hold indefinitely, and still reclaim your BTC when ready.

  • Bitsri is a fully on-chain DeFi protocol and available globally. If you can connect to Web3 and hold Bitcoin, you can use Bitsri. No region locks, no restrictions.
