如何使用 web3gl 将合约发送到智能合约
How to send contract using web3gl to smart contract
我试图将合同从 web3gl 发送到 BUSD。
但我不确定如何传递参数和价值。
请给我一些帮助。
// smart contract method to call
string method = "transfer";
// abi in json format

BUSDImplementation.sol
function transfer(address _to, uint256 _value) public whenNotPaused returns (bool) {

如何为 address _to 和 unit256 value 发送参数？
您可以在 JSON 数组中发送参数。例如，如果您的智能合约方法中有一个地址和一个单位。您可以将参数发送为：
string args = "[\"0x76f3074221Daa81153961Bfff805E41f041753cF\",\"1\"]";
