walletWatchAssets method
Requests that the user tracks the token in MetaMask.
Returns bool
true
if token is successfully added.
Most Ethereum wallets support some set of tokens, usually from a centrally curated registry of tokens. wallet_watchAsset enables web3 application developers to ask their users to track tokens in their wallets, at runtime. Once added, the token is indistinguishable from those added via legacy methods, such as a centralized registry.
Implementation
Future<bool> walletWatchAssets(WatchAssetOptions options,
[String type = 'ERC20']) =>
request<bool>(
'wallet_watchAsset', WatchAssetParams(type: type, options: options));
