Testnet

Chain ID: 20143·Symbol: MON

Monad Devnet is an EVM-compatible blockchain with Chain ID 20143 and native token MON. This page lets you add Monad Devnet to MetaMask, Rabby Wallet, OKX Wallet or Trust Wallet in one click — no manual Chain ID or RPC entry required.

What is Monad Devnet?

Monad Devnet 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 Monad Devnet once you add the network configuration.

Why do you need to add Monad Devnet to your wallet?

MetaMask and most wallets only come pre-configured with Ethereum Mainnet. To transact, swap tokens, or use dApps on Monad Devnet, 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 Monad Devnet 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 Monad Devnet network.

Frequently asked questions

Is it safe to add Monad Devnet 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 Monad Devnet Chain ID?▾

The Chain ID of Monad Devnet is 20143. This unique number identifies the network and prevents MetaMask and other EVM wallets from mixing up transactions across different chains.

Do I need MON tokens to use Monad Devnet?▾

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

What is the Monad Devnet RPC endpoint?▾

An RPC endpoint is the server address your wallet uses to communicate with the Monad Devnet 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 Monad Devnet already exists when I click Add — what do I do?▾

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

I added Monad Devnet 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.
