# bridge-usdt0-evm

A simple package that lets EVM wallet accounts bridge USD₮0 tokens across chains. This package provides a clean API for moving tokens from EVM source chains to both EVM and non-EVM destinations using the LayerZero protocol and USD₮0 bridge system.

## Features

* **Cross-Chain Bridge**: Move USD₮0 tokens between supported blockchains
* **LayerZero Integration**: Uses LayerZero protocol for secure cross-chain transfers
* **Expanded Multi-Chain Support**: Bridge across 25+ networks including Ethereum, Arbitrum, Optimism, Polygon, Berachain, Monad, and more
* **Non-EVM Destinations**: Bridge from EVM chains to Solana, TON, and TRON
* **Account Abstraction**: Works with both standard EVM wallets and ERC-4337 smart accounts
* **Fee Management**: Built-in fee calculation and bridge cost estimation
* **Token Support**: Supports USD₮0 and XAU₮0 (Tether Gold) across supported routes
* **Route Overrides**: Optional per-call `oftContractAddress` and `dstEid` overrides in `BridgeOptions`
* **TypeScript Support**: Full TypeScript definitions included
* **Memory Safety**: Secure transaction handling with proper error management
* **Provider Flexibility**: Works with JSON-RPC URLs and EIP-1193 browser providers

## Supported Networks

This package supports bridging from EVM source chains to EVM and non-EVM destination chains.

### Source Chains (EVM)

* **Ethereum** (Chain ID: 1)
* **Arbitrum** (Chain ID: 42161)
* **Optimism** (Chain ID: 10)
* **Polygon** (Chain ID: 137)
* **Berachain** (Chain ID: 80094)
* **Ink** (Chain ID: 57073)
* **Plasma** (Chain ID: 9745)
* **Conflux eSpace** (Chain ID: 1030)
* **Corn** (Chain ID: 21000000)
* **Avalanche** (Chain ID: 43114)
* **Celo** (Chain ID: 42220)
* **Flare** (Chain ID: 14)
* **HyperEVM** (Chain ID: 999)
* **Mantle** (Chain ID: 5000)
* **MegaETH** (Chain ID: 4326)
* **Monad** (Chain ID: 143)
* **Morph** (Chain ID: 2818)
* **Rootstock** (Chain ID: 30)
* **Sei** (Chain ID: 1329)
* **Stable** (Chain ID: 988)
* **Unichain** (Chain ID: 130)
* **XLayer** (Chain ID: 196)

### Destination Chains

* **EVM destinations**: All supported EVM chains listed above
* **Solana** (EID: 30168)
* **TON** (EID: 30343)
* **TRON** (EID: 30420)

**Note**: Token support is determined by the contracts deployed on each chain. The protocol checks for `oftContract`, `legacyMeshContract`, and `xautOftContract` to determine available tokens.
