Supported chains

Chains supported via WaaP SDK​

WaaP SDK supports all EVM chains. dApps integrating with WaaP SDK can add custom chains according to EIP 3085 via wallet_addEthereumChain.

Add Custom Chain​

try {
  await window.waap.request({
    method: 'wallet_addEthereumChain',
    params: [{
      chainId: '0x89', // 137 in hex
      chainName: 'Polygon Mainnet',
      nativeCurrency: {
        name: 'MATIC',
        symbol: 'MATIC',
        decimals: 18
      },
      rpcUrls: ['https://polygon-rpc.com/'],
      blockExplorerUrls: ['https://polygonscan.com/']
    }]
  });
} catch (error) {
  console.error('Failed to add chain:', error);
}

Switch Chain​

To switch to a different chain, use wallet_switchEthereumChain:

try {
  await window.waap.request({
    method: 'wallet_switchEthereumChain',
    params: [{ chainId: '0x89' }], // chainId must be in hexadecimal numbers
  });
} catch (error) {
  console.error('Failed to switch chain:', error);
}
