Local Devnet¶
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.
The following sections provide essential information for configuring your local development tools to work with the DataHaven devnet. You’ll also find details on pre-funded accounts and MSP endpoints for testing your integrations.
| Network | Network Type | Native Asset Symbol | Native Asset Decimals |
|---|---|---|---|
| DataHaven Local Devnet | Local Devnet | SH | 18 |
Network Configuration¶
To interact with the network, use the following information to configure DataHaven's local devnet within the developer tools you are using:
| Variable | Value |
|---|---|
| Chain ID | |
| Public RPC URLs | |
| Public WSS URLs | |
Block Explorers¶
The local devnet does not include hosted explorers. Use tools such as:
- Hardhat local chain inspection
- Polkadot.js Apps (local Substrate RPC)
Pre-Funded Devnet Accounts¶
The local devnet ships with multiple pre-funded test accounts, which reset every time the devnet restarts. These can be imported into MetaMask or used in scripts.
| Account Name | EVM Address | Private Key |
|---|---|---|
| Alith | |
|
| Baltathar | |
|
| Charleth | |
|
| Dorothy | |
|
| Ethan | |
|
| Faith | |
|
| Goliath | |
|
Note
These keys are for local development only and should never be used on public networks. Every time you start the local devnet, all balances and states are reset. Use of these accounts on production networks will result in loss of funds.
MSP Service Endpoint¶
Use the following base URL when interacting with an MSP through the StorageHub SDK:
