Bridge
Use Rails to bridge any USDT balance to an available chain.
What is Bridging?
Bridging is the process of moving a token like USDT from one blockchain network to another. The same asset can exist across multiple chains, but funds on one chain can't be used directly on another. A bridge locks or burns your tokens on the source chain and releases the equivalent amount on the destination chain, so your USDT becomes usable on the network you choose. With Rails, your USDT starts on the Ink network and you can bridge it to any supported chain, such as Arbitrum, that better suits where you want to use or hold your funds.
How to bridge USDT
The bridge function lets you move your USDT from the Ink network to other available chains. Ensure you have USDT in your linked wallet before you attempt to bridge.
