Suggest a token

Use wallet_watchAsset to ask the wallet to track a token. The user decides whether to add it. This does not transfer tokens or establish that a token is trustworthy.

Confirm the selected network and verify the contract address, symbol, and decimals. Call the method from a user action.


const provider = window.$onekey?.ethereum;
if (!provider) throw new Error('OneKey Ethereum provider is unavailable.');
 
try {
  const wasAdded = await provider.request({
    method: 'wallet_watchAsset',
    params: {
      type: 'ERC20',
      options: {
        address: '<TOKEN_CONTRACT_ADDRESS>',
        symbol: 'TOKEN',
        decimals: 18, // Replace with the token's actual decimals.
        image: 'https://example.com/token.png',
      },
    },
  });
  console.log(wasAdded ? 'Token added.' : 'Token was not added.');
} catch (error) {
  console.error(error.code, error.message);
}
