About Ink Sepolia
Ink Sepolia is a public testnet for the Ink blockchain, developed by Kraken. It serves as a testing environment for developers to build and test decentralized applications (dApps) before deploying them on the mainnet. The network utilizes Sepolia Ether (ETH) as its native currency, with 18 decimal places, and operates under Chain ID 763373.
As a testnet, Ink Sepolia mirrors the Ink mainnet's features, allowing developers to simulate real-world conditions without the risk of using actual assets. This setup enables efficient testing and debugging of smart contracts and dApps. Developers can interact with the network through various RPC endpoints, including HTTPS and WebSocket protocols, and monitor transactions and contract interactions via the Ink Sepolia Explorer.
To facilitate seamless integration, Ink Sepolia is compatible with standard Ethereum development tools and wallets, such as MetaMask. This compatibility ensures that developers can leverage existing tools and workflows when building on the Ink Sepolia testnet.
