What are Cross Chain Bridges for API3?

Cross-chain bridges are platforms or protocols that enable the transfer of assets and data between different blockchain networks, facilitating interoperability across otherwise isolated blockchains. These bridges allow users to move tokens, cryptocurrencies, or other digital assets seamlessly between two distinct blockchains without relying on a central intermediary. By unlocking cross-chain capabilities, users can leverage the unique features of each blockchain, such as different consensus mechanisms or specialized use cases, while maintaining the security and decentralization of both networks. Cross-chain bridges often use wrapped tokens or smart contracts to facilitate the exchange of assets across chains, improving liquidity and expanding the potential for decentralized applications (dApps). This technology is crucial for advancing the adoption and scalability of decentralized finance (DeFi) and other blockchain-based applications.

    Harmony

    Harmony is an open and fast blockchain. Our mainnet runs Ethereum applications with 2-second transaction finality and 100 times lower fees. Harmony’s secure bridges offer cross-chain asset transfers with Ethereum, Binance and other chains. Harmony serves as a platform for creators to connect with their community. Harmony’s bridges can connect any Proof-of-Work and Proof-of-Stake chains. Our FlyClient architecture are fully trustless and highly gas-efficient. Currently, our bridges for Ethereum and Binance Smart Chain secure tens of millions cross-chain assets. Developers simply change Chain ID and enjoy faster EVM executions identical at the bytecode level. They can use their familiar and standard Web3 tooling to easily migrate to Harmony. What about users? They can continue to use MetaMask or Ledger — but now pay minimal fees. Any Ethereum wallets or portals can work on Harmony without code changes or new installs.
