About addresses

An address reference and verification skill for developers working with contracts on Monad. It stresses checking the requested network through an explorer or RPC and provides lists and repositories for finding addresses.

Key features

  1. 01Verify addresses by network
  2. 02Check contract code via explorer or RPC
  3. 03Lists common Monad contract addresses
  4. 04Points to protocol and token repositories

Use cases

  1. 01Verify a contract address before interaction
  2. 02Check whether a contract has code on a network
  3. 03Find a Monad protocol or token address

Install

Copy the command and run it in a terminal.

CRITICAL

⚠️ Always verify addresses using the explorer before interacting with smart contracts. Never hallucinate a smart contract address, wrong addresses can lead to loss of funds.

Monad Mainnetmonadscan.com
Monad Testnettestnet.monadscan.com

Make sure you have zero doubts about which network the user is asking the address for whether mainnet or testnet, if you are unsure then ask the user. Do not provide mainnet address when a testnet address was asked for.

How to verify if a smart contract has code on a network.

If Foundry toolkit is installed.

Monad Mainnet
# Check bytecode exists
cast code [smart_contract_address] --rpc-url https://rpc.monad.xyz
Monad Testnet
# Check bytecode exists
cast code [smart_contract_address] --rpc-url https://testnet-rpc.monad.xyz

If Foundry toolkit is not installed you can call "eth_getCode" RPC method on the respective RPC endpoint for the network with the smart contract address and verify using the response.

Protocols repo

The protocols repo contains smart contract address (testnet and mainnet) for well known protocols and projects in the monad ecosystem.

If you need an address that is not found from the tables above check the protocols repo for the smart contract address.

Protocol repo GitHub URL: https://github.com/monad-crypto/protocols

Addresses in protocols repo are organized by testnet and mainnet and each protocol has it's own file.

For example:

Smart contract addresses for Clober protocol on Monad mainnet is in file: protocols/mainnet/clober.jsonc

Each file has a JSON object with property "addresses" which is object with items as "name" and address of each smart contract associated with the respected protocol.

Similarly for testnet, the route is protocols/testnet/[protocol_name].json

Token list repo

The token list repo contains smart contract address (mainnet only) for well known tokens in the monad ecosystem.

If you need an address for a token that is not found from the tables above check the token list repo for smart contract address.

Token list repo GitHub URL: https://github.com/monad-crypto/token-list

Addresses in token list repo are organized by token names in folders, there is a mainnet folder inside which there are folders with token names inside each folder is a json with the address.

CRITICAL

⚠️ After looking at all the available options above, if you are still not able to find the address ask the user for it but do not at all hallucinate an address and do not provide mainnet address when a testnet address was asked for.
