Developers – Quick Start

Essential information for developers who want to build on DouChain.

Developers – Quick Start

If you're a developer looking to build on DouChain, this page gives you the essentials.

DouChain is:

  • a high-throughput, dynamically sharded L1
  • designed for social, AI, gaming, and on-chain markets
  • compatible with both SVM-style and EVM-style execution

Connect {#connect}

At pre-launch, DouChain is preparing its public testnet.

When the testnet is live, this section will include:

  • RPC URLs
  • chain IDs
  • instructions for adding DouChain to popular wallets (MetaMask, Phantom, etc.)

For now, you can:

Get Testnet $DOU {#get-testnet-dou}

Once the faucet is available, this page will document:

  • how to request testnet $DOU
  • faucet rate limits and requirements
  • example CLI usage for developers

JSON-RPC Overview {#json-rpc}

DouChain will expose JSON-RPC endpoints for:

  • SVM-compatible methods (Solana-style programs)
  • EVM-compatible methods (Ethereum-style contracts)

The goal is to make it easy to reuse existing SDKs:

  • ethers.js, web3.js, viem
  • Solana Web3 SDKs
  • Hardhat / Foundry / Anchor

Detailed method references will be added as the public testnet stabilizes.
