A blockchain bridge is a connection that allows different blockchain networks to communicate and transfer assets between each other. This is important because various blockchains often operate independently, and users may want to move their tokens from one blockchain to another.

Bridges can facilitate the transfer of cryptocurrencies, enabling users to swap tokens without needing to convert them back into fiat currency first. This helps enhance liquidity and flexibility in trading and using digital assets across multiple platforms.

Typically, a bridge works through a smart contract that locks up assets on the originating blockchain while issuing equivalent tokens on the target blockchain. This process ensures that the total supply of tokens remains constant and that the transaction is secure.

In summary, blockchain bridges play a crucial role in improving interoperability between different blockchains, allowing users to take advantage of varied features and opportunities across ecosystems. As the landscape evolves, these bridges are becoming essential tools for enhancing the functionality and usability of digital assets.
