LIP Integration Examples

The Bridge

The LiquidsFi Cross-Chain Bridge is a secure, decentralized bridging system that enables seamless transfers of stablecoins such as USDC and USDT between Soroban/Stellar and supported EVM chains. At its core, the bridge uses:

• The Liquidity Protocol (lock-and-release / burn-and-mint mechanisms)

• The LIP Oracle Network as the trust-minimized cross-chain messaging layer

This combination ensures safe and efficient token transfers without centralized custodians.

The current implementation supports bidirectional bridging of stablecoins between:

• Ethereum ↔ Soroban

• Avalanche ↔ Soroban

The available bridge liquidity pools are shown below:

The Liquidity Protocol

The bridge also includes a Liquidity Protocol that allows users to add liquidity and earn rewards. Deposited liquidity can be withdrawn at any time.

When liquidity is added:

• The deposited assets are locked in the Liquidity Protocol

• The user receives a protocol token representing their share (1:1 ratio)

• When withdrawing, the protocol token is burned, and the underlying stablecoins are released

Example: If a user deposits 1,000 USDC, they receive 1,000 lUSDC. When the user withdraws, lUSDC is burned and 1,000 USDC is released.
