Sepolia 測試網

Sepolia Testnet is an Ethereum community-driven test network designed to provide developers with a stable and realistic environment for testing smart contracts and decentralized applications before deploying them on the Ethereum mainnet. It replicates the Ethereum mainnet's functionality but operates with test tokens, allowing developers to experiment without financial risk. Sepolia is one of the official Ethereum testnets, supported by various infrastructure providers and integrated into developer tools.

The testnet includes deployed protocol contracts and endpoint infrastructure compatible with LayerZero's interoperability protocol, enabling developers to test cross-chain messaging and token transfers in a controlled setting. Sepolia supports the LayerZero Endpoint V2 with a unique chain ID (11155111) and includes multiple decentralized verifier networks (DVNs) and omnichain fungible tokens (OFTs) for comprehensive testing of cross-chain applications.

What distinguishes Sepolia from other Ethereum testnets is its active maintenance by the Ethereum community and integration with LayerZero's cross-chain messaging protocol, which facilitates testing of omnichain applications. It serves as a reliable staging ground for developers building interoperable DeFi, DAO tooling, and enterprise blockchain solutions. Developers can get started by accessing the official Sepolia endpoints, reviewing LayerZero's detailed documentation, and leveraging SDKs and developer tools provided by LayerZero Labs. The testnet's open GitHub repository allows community contributions and transparency in development.
