Monad: chain ID, RPC URLs and explorers
The two Monad explorer sites in Monad's own docs are MonadVision at monadvision.com and Monadscan at monadscan.com, and both cover mainnet, chain ID 143. Monad is an EVM-compatible layer 1 blockchain whose coin, MON, trades at $0.0161 on CoinGecko at this check.

What Is Monad
Monad is a layer 1 blockchain that runs Ethereum contracts unchanged and aims for far more speed than Ethereum mainnet. Its docs claim full EVM bytecode compatibility, full Ethereum RPC compatibility, 10,000 transactions per second, a block every 300ms and finality in 600ms.1
The speed comes from how blocks get processed. MonadBFT handles consensus, transactions run in parallel where they do not touch the same state, and execution trails consensus instead of blocking it, a design the docs call asynchronous execution. A custom database, MonadDb, stores the state.
Monad Explorer Sites
Monad explorer sites listed on Monad's network information page are MonadVision, built by BlockVision, and Monadscan, built by Etherscan. Either one looks up a 0x address, a transaction hash or a token contract.
The docs also point to gmonads.com for a live view of the network, Phalcon Explorer and Tenderly for detailed traces, and Jiffyscan for smart account operations. Circle links its Monad USDC contract on MonadVision.
Monad RPC URLs Tested Today
Five Monad RPC URLs from Monad's docs passed today's test: each returned 0x8f, which is 143, to an eth_chainId call on November 8, 2026.
https://rpc.monad.xyz: Monad Foundation, 20 requests per second.https://rpc1.monad.xyz: Monad Foundation, 20 requests per second.https://rpc2.monad.xyz: Goldsky Edge, 300 requests per 10 seconds.https://rpc3.monad.xyz: Ankr, 300 requests per 10 seconds, no historical state.https://rpc-mainnet.monadinfra.com: Monad Foundation, 20 requests per second.
The docs say the Monad Foundation endpoints are not for production workloads. Two more endpoints answered with 143 today, but they are missing from Monad's list, so they stay off this page.
Monad Chain ID for Wallets
The Monad chain ID for wallets is 143 in Monad's docs, and chainid.network lists the same 143 with the symbol MON, so the two sources agree.3 To add the network by hand, enter the name Monad Mainnet, chain ID 143, symbol MON, one RPC URL from the list above and https://monadscan.com as the explorer.
The testnet is a separate network with chain ID 10143 and a faucet at faucet.monad.xyz.4 Testnet MON has no value. The Monad testnet faucet page tracks which faucets work today, and the chain directory lists every other network this site covers.
USDC and USDT on Monad
USDC on Monad has an official contract, 0x754704Bc059F8C67012fEd69BC8A327a5aafb603, on Circle's address list, and a symbol call over the public RPC returned USDC today. The USDC explainer covers who issues it.
Tether does not list an official USDT contract on Monad as of November 8, 2026.6 Any token called USDT on Monad is a contract Tether does not list itself. The USDT contract address page shows the chains Tether does list.
How Monad Differs From Ethereum
Monad differs from Ethereum in a few rules that catch developers and users moving over, according to its docs:7
- Fees are charged on the gas limit you set, not the gas a transaction uses, so an oversized gas limit costs real MON.
- Contracts can be up to 128 KB, against 24 KB on Ethereum.
- Blob transactions from EIP-4844 are not supported.
The public mainnet opened on November 24, 2025, The Block reported, with 50.6% of all MON locked at launch. Block 1 of chain 143 is stamped May 14, 2025, so the chain was producing blocks for months before the public opening.
Questions People Ask About Monad: chain ID, RPC URLs and explorers
These are the questions people ask next about Monad: chain ID, RPC URLs and explorers.
What is the Monad explorer?
The Monad explorer can be either MonadVision at monadvision.com or Monadscan at monadscan.com, the two block explorers Monad's docs list for mainnet. Both search addresses, transactions and tokens on chain ID 143, and both have testnet versions.
What is the Monad chain ID?
The Monad chain ID is 143 for mainnet, or 0x8f in hex, as Monad's docs and chainid.network both list it. The Monad testnet uses chain ID 10143. A wallet set to the wrong one will show different balances.
What is the Monad RPC URL?
The Monad RPC URL in Monad's docs is https://rpc.monad.xyz, run by the Monad Foundation with a limit of 20 requests per second. Goldsky's https://rpc2.monad.xyz and Ankr's https://rpc3.monad.xyz allow 300 requests per 10 seconds. All passed our test today.
Is Monad EVM compatible?
Monad is EVM compatible, and its docs claim full bytecode and Ethereum RPC compatibility, so Ethereum wallets and tools connect with chain ID 143. A few rules differ, such as fees charged on the gas limit and no blob transactions.
