Cross-Chain Bridge

USDT0 across all chains via LayerZero

Bridge USDT seamlessly between 19+ supported chains using LayerZero's OFT (Omnichain Fungible Token) standard. Same token, any chain, instant liquidity.

Advantages

Benefits

Unified Liquidity

USDT0 maintains the same value and properties across all chains. No wrapped tokens or liquidity fragmentation.

Fast Finality

LayerZero provides secure cross-chain messaging with configurable security parameters.

Lower Fees

Direct chain-to-chain transfers without intermediate tokens or multiple swaps.

Native Integration

Built into the t402 protocol. Accept payments on any chain, settle on your preferred chain.

Under the Hood

Technical Details

LayerZero OFT Standard

Omnichain Fungible Tokens enable native cross-chain transfers. The token is burned on the source chain and minted on the destination.

Security Model

LayerZero uses decentralized verifier networks (DVNs) to validate cross-chain messages. Configurable security for different risk tolerances.

19+ Supported Routes

USDT0 can be bridged between Ethereum, Arbitrum, Base, Optimism, Berachain, Unichain, Ink, Avalanche, BNB Chain, zkSync, Scroll, Linea, and more.

Gas Optimization

Batched bridge operations reduce per-transfer costs. Automatic route optimization for best prices.

Code Example

Bridge USDT0 from Arbitrum to Base

import { bridge } from "@t402/wdk-bridge";

const result = await bridge({
  token: "USDT0",
  from: {
    network: "eip155:42161", // Arbitrum
    address: userAddress,
  },
  to: {
    network: "eip155:8453", // Base
    address: userAddress,
  },
  amount: "100.00",
});

console.log("Bridge initiated:", result.srcTxHash);
console.log("Destination:", result.dstTxHash);
