To bridge crypto, you will need to use a crypto bridge that supports the two blockchains you want to transfer assets between. First, select your source chain – say, Solana or Polygon – and the destination chain, such as Ethereum or Arbitrum. Then select the asset you want to bridge and confirm the transaction. For example, ChangeNOW's bridge chain solution makes cross-chain bridging easier with its fast and secure process.

The crypto bridge is designed to enable asset and data movement across different blockchains. Due to the isolated nature of blockchain platforms, interoperability is provided by a cross-chain bridge: it locks assets on one chain and issues its equivalent tokens on another.

In the case of crypto bridging, this greatly depends on a blockchain network: over ChangeNOW, the most cross-chain bridging operations take less than 5 minutes to complete. However, congestion on networks like the Arbitrum bridge or Solana bridge can sometimes cause delays.

ChangeNOW's token bridge solutions can facilitate swapping BTC for Avalanche-compatible assets quickly and securely.

Cross-chain refers to the interoperability between blockchains that allows seamless asset and data movement across networks. Bridges like those offered by ChangeNOW enable this process, which helps users swap tokens between different ecosystems, such as Ethereum, Solana, and Arbitrum.

A cross-chain bridge works by locking assets on the source chain and minting an equivalent amount on the destination chain. For example, if you use a defi bridge to move SOL from Solana to Ethereum, the bridge locks the original SOL and releases a bridge coin representing SOL on Ethereum (wrapped Solana, or wSol). Some bridges use liquidity pools to facilitate instant swaps without locking assets.

To bridge Polygon to Ethereum, you can use ChangeNOW's token bridge. Simply select Polygon as the source chain, Ethereum as the destination chain, choose your tokens, and confirm the transaction.
