# Asset Bridging Tutorials

UniPort supports bidirectional cross-chain transactions of BTC/BRC20/ARC20 assets between the Bitcoin network and smart contract ecosystems such as Ethereum/Arbitrum/Sui. It also facilitates bidirectional cross-chain transactions of assets among smart contract ecosystems like Ethereum/Arbitrum/Sui.
