Cross-chain lending infrastructure

Borrow across chains,
without bridges.

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.

The problem & our approach

Liquidity is trapped on separate chains. Bridges are the weak link.

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.

VCC

Virtual Collateral Certificates

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.

URO

Unified Rate Oracle

Aggregates lending rates from six protocols across five chains every 30 seconds, backed by Chainlink and Pyth, so BLX rates stay competitive and solvent.

CCLE

Cross-Chain Liquidation Engine

Liquidators on any supported chain can close under-collateralised positions on any other chain — a wider, faster liquidator set than any single-chain market.

How it works

Deposit on chain A. Borrow on chain B. In seconds.

STEP 01

Deposit collateral

Lock WETH in the CollateralVault on Ethereum. Your asset stays on its native chain and never leaves.

STEP 02

Mint a VCC

The protocol mints a signed Virtual Collateral Certificate recording the asset, amount, oracle price, health factor and expiry.

STEP 03

Relay cross-chain

The VCC is transmitted to Solana through a generalised messaging layer with an independent verifier — typically in 3–5 seconds.

STEP 04

Borrow & repay

Borrow USDC on Solana against the certificate. Repay to unlock your WETH on Ethereum. No bridge, no wrapped asset, no custodian.

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.

Security

Engineered to fail closed, not open

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.

Token

$BLX — governance and value accrual

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.
