Add Onyx Mainnet to a wallet and make a safe first transaction.
The fastest way to add Onyx to MetaMask or another EVM wallet is from the Onyx Explorer: open the explorer and use the Add Onyx Network control in the bottom-left corner for a one-click wallet prompt.
You can also enter the network details manually:
Network name
Onyx Mainnet
RPC URL
https://rpc.onyx.org
Chain ID
327
Currency symbol
XCN
Explorer
For dApp / programmatic wallet setup (wallet_addEthereumChain) and RPC eth_chainId verification, see Developer Guide → Getting Started.
XCN is represented with 18 decimals through JSON-RPC, but the native ledger has 8-decimal precision. See XCN Decimal Handling.
A transfer to a new address can require substantially more gas because the account is created on first receipt. Always use eth_estimateGas; never hardcode 21,000. See Lazy Account Creation.
Read eth_gasPrice when preparing a transaction and handle RPC errors instead of assuming Ethereum Mainnet fee-market behavior.
