Add ARC Mainnet to Your Wallet — MetaMask, OKX, Rabby, Trust Wallet

Chain ID: 1243·Symbol: ARC

ARC Mainnet is an EVM-compatible blockchain with Chain ID 1243 and native token ARC. This page lets you add ARC Mainnet to MetaMask, Rabby Wallet, OKX Wallet or Trust Wallet in one click — no manual Chain ID or RPC entry required.

What is ARC Mainnet?

ARC Mainnet is an EVM (Ethereum Virtual Machine) compatible blockchain network. Any EVM wallet — MetaMask, Rabby, OKX Wallet, Trust Wallet, Coinbase Wallet — can connect and transact on ARC Mainnet once you add the network configuration.

Why do you need to add ARC Mainnet to your wallet?

MetaMask and most wallets only come pre-configured with Ethereum Mainnet. To transact, swap tokens, or use dApps on ARC Mainnet, you need to add the network first. Entering an incorrect Chain ID or RPC can put your assets at risk. Use the "Add to wallet" button above — data sourced directly from chainid.network, the canonical Ethereum chain registry.

How to add ARC Mainnet to your wallet

1
Click Add to wallet
Press the "Add to wallet" button above. MetaMask, OKX Wallet, Rabby Wallet or Trust Wallet will show a popup asking you to confirm adding the ARC Mainnet network.
2
Confirm in your wallet
Your wallet shows the ARC Mainnet network details: Chain ID 1243, native token ARC. Verify the Chain ID is correct, then click "Approve" or "Add Network".
3
Switch to the new network
After confirming, your wallet automatically switches to ARC Mainnet. You can start transacting right away — you will need ARC to pay gas fees.

Important notice

•Always verify Chain ID 1243 before confirming — attackers sometimes create fake networks with similar names but different Chain IDs
•You need ARC tokens in your wallet to pay gas fees for transactions on ARC Mainnet
•Data on this page is sourced from chainid.network — the community-verified Ethereum chain registry
•If the "Add to wallet" button doesn't work, your wallet may not support wallet_addEthereumChain — add the network manually using the details below

Frequently asked questions

Is it safe to add ARC Mainnet to MetaMask?▾

Yes, if you use the "Add to wallet" button on this page. Data is sourced from chainid.network — the community-audited Ethereum registry. Adding a network does not expose your private key or grant any permissions to the dApp.

What is ARC Mainnet Chain ID?▾

The Chain ID of ARC Mainnet is 1243. This unique number identifies the network and prevents MetaMask and other EVM wallets from mixing up transactions across different chains.

Do I need ARC tokens to use ARC Mainnet?▾

Yes. Every transaction on ARC Mainnet requires ARC to pay gas fees. You can purchase ARC on exchanges and bridge it to ARC Mainnet, or use a faucet if this is a testnet.

What is the ARC Mainnet RPC endpoint?▾

An RPC endpoint is the server address your wallet uses to communicate with the ARC Mainnet blockchain — sending transactions, reading balances, and checking state. This page shows live latency for each RPC so you can pick the fastest one.

My wallet says ARC Mainnet already exists when I click Add — what do I do?▾

That's completely normal. If ARC Mainnet is already in your wallet, it will simply switch to that network instead of adding a duplicate — no error or conflict.

I added ARC Mainnet but the network won't load — what's wrong?▾

The most common cause is a broken or overloaded RPC endpoint. Your wallet uses RPC to connect to the blockchain — if the RPC is down, the network won't load even if it was added correctly. Fix: copy a different RPC from the list above (prefer green low-latency ones), then go to Settings → Networks in your wallet and replace the old RPC with the new one. Watch the tutorial video above for step-by-step instructions on updating your RPC.
