Supply collateral on one blockchain and borrow on another — no bridging, no wrapped assets, fully non-custodial. BLX moves a cryptographic claim on your collateral, never the asset itself.
DeFi holds over $200B, fragmented across 85+ networks. The only way to move collateral between them has been bridging — the single most exploited component in the ecosystem, with $2.8B+ lost. BLX removes that dependency with three primitives.
Deposit collateral and the protocol mints a signed, expiring proof-of-lock. That certificate — not the asset — travels cross-chain and is accepted as collateral at the destination.
Aggregates lending rates from six protocols across five chains every 30 seconds, backed by Chainlink and Pyth, so BLX rates stay competitive and solvent.
Liquidators on any supported chain can close under-collateralised positions on any other chain — a wider, faster liquidator set than any single-chain market.
Lock WETH in the CollateralVault on Ethereum. Your asset stays on its native chain and never leaves.
The protocol mints a signed Virtual Collateral Certificate recording the asset, amount, oracle price, health factor and expiry.
The VCC is transmitted to Solana through a generalised messaging layer with an independent verifier — typically in 3–5 seconds.
Borrow USDC on Solana against the certificate. Repay to unlock your WETH on Ethereum. No bridge, no wrapped asset, no custodian.
Deposit collateral — your WETH is locked on Ethereum and never moves.
Model a position end to end. Choose collateral and a borrow on a different chain, and watch the health factor, maximum borrow and liquidation price update in real time.
Illustrative parameters for demonstration. Prices, rates and collateral factors are indicative and do not reflect live market data. Digital-asset borrowing carries risk, including liquidation and loss of collateral.

Two independent audits, conservative caps, a funded insurance reserve and a seven-figure bug bounty. Because collateral recognition depends on cross-chain messages, the protocol restricts new risk the moment messaging degrades.
Live on Immunefi for critical smart-contract findings, with coordinated disclosure and a funded insurance reserve targeting 5% of TVL.
A fixed supply of 1,000,000,000 BLX. Protocol fees flow to stakers, treasury and insurance. Value accrues as a function of borrow volume and utilisation — of real usage, not emissions.
Testnet, dual audits and strategic round closed.
