3. What did you see instead?

@vahidsabet, you may try https://developers.tron.network/reference/account-getaccount this API to get the balance of given addresses. balance is the currently available amount of TRX and asset is TRC-10 balance. For TRC-20 balance, please refer to https://developers.tron.network/reference/triggerconstantcontract-1, and use balanceOf(address) for function_selector.

[vahidsabet]

Thanks dear @Jake151987 . So there isn't a single call to get both TRX and other tokens?

[Jake151987]

@vahidsabet, sorry no single API could achieve that.

I try to get balance of TRC-20 with api “/wallet/triggersmartcontract”，why the response is {
"result": {
"code": "CONTRACT_VALIDATE_ERROR",
"message": "this node does not support constant"
}
}

by params
{
"contract_address":"TR7NHqjeKQxGTCi8q8ZY4pL8otSzgjLj6t",
"function_selector":"balanceOf(address)",
"owner_address":"TM442vw56hUxmYmZ5L2q3cqZy7ZSBQgRXn",
"visible" : true
}

@FerdyCai I guess you are rolling with your own node? In your node config file, find the item supportConstant and set it to 'true`, then you may use triggerconstantcontract to query the balance of your TRC-20 token.

[FerdyCai]

@ExOCeo,yes,i am rolling with my own node. but https://developers.tron.network/reference/triggersmartcontract here also can not get balance of TRC-20 .

[FerdyCai]

@ExOCeo It works after change supportConstant to true. Thank you very much.
