Wallets · chain id · RPC

Add Igneum to MetaMask.

Igneum runs the Ethereum virtual machine, so MetaMask and every other Ethereum wallet work unchanged. The wallet needs four things: the chain id, an RPC URL, the symbol IGN and 18 decimals. The button below sends them to the wallet with the standard wallet_addEthereumChain request; the wallet shows them to you and asks before adding anything. Nothing on this page asks for a seed phrase or a key. Nobody from Igneum will ask for your seed.

Public testnet · coming

Igneum testnet

The network the one-click miner app joins at public testnet. Coins on it have no value and the chain resets with notice (testnet terms).

Network name: Igneum Testnet
Chain id: 4462 (0x116e)
RPC URL: https://rpc.testnet.igneum.network (published with the testnet)
Symbol: IGN
Decimals: 18
Explorer: published with the testnet

The button switches on when the public RPC is live.

Devnet · live now

Igneum devnet, through your own node

The Igneum Miner app runs a full node on your machine and serves the Ethereum RPC on it. Point the wallet at that node. The devnet is a developer network: it resets without notice and its coins have no value.

Network name: Igneum Devnet (local node)
Chain id: 4463 (0x116f) on Devnet 3; 4464 (0x1170) after its class v5 floor
RPC URL: http://127.0.0.1:26790
Symbol: IGN
Decimals: 18
Explorer: igneum.network/explorer

Add it by hand

If the wallet has no one-click support, or you prefer to type: MetaMask, Settings, Networks, Add a network manually. Enter the values from the card above. Any wallet that supports custom EVM networks takes the same four fields.

Network name: Igneum Testnet (or Igneum Devnet for your own node).
RPC URL: the one on the card.
Chain id: 4462 for the testnet, 4463 for the devnet.
Currency symbol: IGN. Decimals: 18.

For builders

The same request from your own page or app, so your users land on the right chain:

await window.ethereum.request({
  method: 'wallet_addEthereumChain',
  params: [{
    chainId: '0x116e',                      // 4462, the Igneum testnet (0x116f = 4463, the devnet)
    chainName: 'Igneum Testnet',
    nativeCurrency: { name: 'Igneum', symbol: 'IGN', decimals: 18 },
    rpcUrls: ['https://rpc.testnet.igneum.network'],
    blockExplorerUrls: []
  }]
});

Igneum signs transactions with the Ethereum rules (EIP-155, EIP-1559 and legacy envelopes). A transaction signed for another chain id is refused. Gas has two dimensions on Igneum, execution and proving, and the node folds the second into the price it quotes, so eth_gasPrice and eth_estimateGas work as they do on Ethereum. The litepaper has the differences.

The app and the Igneum Wallet

The Igneum Ember app (still labelled Igneum Miner in its window) makes an address for your earnings and shows you its seed phrase once. That address is an ordinary Ethereum account: import the seed into MetaMask and the balance is there. Igneum Wallet 0.1.5 is out for macOS and verifies finality itself; its Apps tab is in the roadmap. MetaMask works today and is the way in on Windows and Linux.

Testnet coin for testing: the faucet sends 10 IGN per address per day. Chain ids 4461 (mainnet), 4462 (testnet) and 4463 (devnet) are fixed in the node; Devnet 3 answers 4463 until its class v5 floor, then 4464. The testnet RPC URL above is a placeholder until the testnet opens; this page is updated the day it does.
