Caldera Series (8): ERA Cross-Chain Read and Write Practice
Cross-chain operations are the future trend of blockchain, and the ERA token provides powerful support for cross-chain read and write within Caldera's Metalayer framework. Cross-chain read and write refers to sending messages (writing) or querying data (reading) between different blockchains. The $ERA token, as the universal currency of the Caldera ecosystem, is used not only to pay for gas fees for cross-chain operations but also ensures the security of message transmission through a staking incentive mechanism.
For example, in a practical scenario: a user wants to query smart contract data on chain B from chain A. They only need to initiate a read request through the Metalayer interface, and the ERA token will automatically handle the gas fees, completing the process in just a few seconds. Similarly, write operations can also be achieved using the ERA token, such as triggering a contract function on chain B from chain A to complete asset transfers or state updates. This efficient cross-chain interaction benefits from the support of the Hyperlane protocol, with the ERA token acting as a lubricant.
For developers, Caldera provides TypeScript SDK and Widget SDK, simplifying the development process for cross-chain read and write. Whether building decentralized exchanges or cross-chain NFT markets, the ERA token helps developers quickly implement functionality. Users can enjoy a low-cost, high-efficiency operational experience, and ERA's cross-chain practice is setting a new benchmark for blockchain interoperability.
