/walletsolidity/getdelegatedresourcev2 - Tron

Example code for the getdelegatedresourcev2 Solidity API method. Complete guide on how to use getdelegatedresourcev2 Solidity API method in GetBlock Web3 documentation.

This endpoint returns the Stake 2.0 resources delegated from one account to another, read from confirmed state on the Solidity node.

This is a Solidity-node endpoint. It returns only confirmed, irreversible data, so it is the correct interface for balance and payment verification. The Fullnode serves the same operation at https://go.getblock.io/<ACCESS-TOKEN>/wallet/getdelegatedresourcev2 over the latest, possibly unconfirmed state.

Parameters

Parameter	Type	Required	Description
fromAddress	string	Yes	Address that delegated the resource
toAddress	string	Yes	Address that received the delegated resource
visible	boolean	No	Accept and return addresses in base58 format
