Testnet¶
DataHaven is a fully EVM-compatible decentralized storage and computation platform built as a Substrate-based Layer 1 blockchain. Developers can interact with DataHaven using Ethereum RPCs, popular wallets, and libraries such as MetaMask or viem, while also accessing Substrate APIs for additional features.
