# About TxRelay

### What is TxRelay?

TxRelay is a cross-chain asset bridge built around **Txflow**, our settlement hub. It lets you move major crypto assets between chains like Ethereum, Arbitrum, Base, Polygon and Solana and your account on Txflow.

There are two directions:

* **Deposit**: move assets into Txflow.
* **Withdraw**: move assets out of Txflow to an external network.

### How it feels to use

Bridging with TxRelay is as simple as a transfer. You get a dedicated address for your transfer, send funds to it like any normal transaction, and TxRelay delivers the corresponding amount to your address on the other side. There is no smart-contract interaction, no wrapped tokens, and no manual claiming.

### Why TxRelay?

* **Simple**: bridging is just a transfer.
* **Multi-chain**: one hub connects many networks, with more assets and chains added over time.
* **Secure**: funds are protected by multi-party custody, so no single party can move them alone.
* **Transparent fees**: fees are shown up front and deducted automatically.
