MetaMask Quick Start for ChainID 138
Quick reference for adding ChainID 138 to MetaMask and adding tokens.
Add Network to MetaMask
Method 1: Using the SDK
import { addOrSwitchNetwork } from '@defi-oracle/metamask-sdk';
await addOrSwitchNetwork();
Method 2: Using wallet_addEthereumChain
await window.ethereum.request({
method: 'wallet_addEthereumChain',
params: [{
chainId: '0x8a',
chainName: 'DeFi Oracle Meta Mainnet',
nativeCurrency: {
name: 'Ether',
symbol: 'ETH',
decimals: 18
},
rpcUrls: ['https://rpc.d-bis.org'],
blockExplorerUrls: ['https://explorer.d-bis.org']
}]
});
Method 3: Using Chainlist
- Visit chainlist.org
- Search for "ChainID 138" or "DeFi Oracle Meta"
- Click "Add to MetaMask"
Method 4: Switch to ChainID 138
await window.ethereum.request({
method: 'wallet_switchEthereumChain',
params: [{ chainId: '0x8a' }]
});
Add Token to MetaMask
Using the SDK
import { addToken } from '@defi-oracle/metamask-sdk';
await addToken(
'0xYourTokenAddress',
'WETH',
18,
'https://explorer.d-bis.org/images/tokens/weth.png'
);
Using wallet_watchAsset (EIP-747)
await window.ethereum.request({
method: 'wallet_watchAsset',
params: {
type: 'ERC20',
options: {
address: '0xYourTokenAddress',
symbol: 'WETH',
decimals: 18,
image: 'https://explorer.d-bis.org/images/tokens/weth.png'
}
}
});

Troubleshooting
MetaMask not detected
if (typeof window.ethereum === 'undefined') {
alert('Please install MetaMask');
window.open('https://metamask.io/download/', '_blank');
}
Network already added
If the network is already added, use wallet_switchEthereumChain instead:
try {
await window.ethereum.request({
method: 'wallet_switchEthereumChain',
params: [{ chainId: '0x8a' }]
});
} catch (error) {
// Network not added, add it
if (error.code === 4902) {
await window.ethereum.request({
method: 'wallet_addEthereumChain',
params: [/* network metadata */]
});
}
}
