Wallet Integration

KAURAX is EVM-equivalent, so any Ethereum wallet works. There is no KAURAX wallet to install and no custom cryptography anywhere in this repository.

Adding KAURAX

Print the exact parameters for the running network:

kaurax wallet add

Or fetch them over RPC:

curl -s -X POST http://127.0.0.1:8420 \
  -H 'content-type: application/json' \
  -d '{"jsonrpc":"2.0","id":1,"method":"kaurax_networkDescriptor","params":[]}'

Programmatic add (EIP-3085)

await window.ethereum.request({
  method: "wallet_addEthereumChain",
  params: [{
    chainId: "0x20e4",                        // 8420
    chainName: "KAURAX",
    nativeCurrency: {name: "KAURAX", symbol: "KAX", decimals: 18},
    rpcUrls: ["http://127.0.0.1:8420"],
    blockExplorerUrls: ["http://127.0.0.1:3000"],
  }],
});

The bridge UI at /bridge does exactly this, and also handles wallet_switchEthereumChain when a deposit needs the wallet on the L2 rather than on KAURAX.

Supported

• MetaMask and any EIP-1193 provider
• WalletConnect — works through any EIP-1193-compatible connector; KAURAX requires no

special handling, only the chain parameters above - Rabby, Frame, Coinbase Wallet, hardware wallets via those interfaces - viem, ethers, web3.js

Chain IDs

Both were checked against the public chain registry (chainid.network, 2 750 chains) and are unused. They are not registered — KAURAX has not submitted an entry, and this documentation does not claim otherwise. Both are configurable via KAURAX_CHAIN_ID.

Account abstraction

Not implemented. ERC-4337 works on KAURAX exactly as it works on any EVM chain — the EntryPoint is a contract, and nothing about KAURAX prevents deploying it — but KAURAX operates no bundler, no paymaster and no session-key infrastructure.

Do not describe KAURAX as having account abstraction. It has an EVM that would support it.

A note on KAX

KAX is the native gas asset. It is not an ERC-20 and will not appear in a wallet's token list — it appears as the network's native currency, the way ETH does on Ethereum.

KauraxToken in blockchain/contracts/src/examples/ is an example ERC-20 for testing. It is not KAX.

KAX has no monetary value.
