I'm trying to call the Uniswap Router contract like:
// dummy data
Function: swapExactETHForTokens(uint256 amountOutMin, address[] path, address to, uint256 deadline)
MethodID: 0x7ff36ab5
[0]: 000000000000000000000000000000000000000000000000000000dd0f593444

In my TypeScript code I have:
const abi = web3.eth.abi.encodeFunctionCall(
{
type: 'function',
name: 'swapExactTokensForTokens',
inputs: [
{
name: 'amountIn',
type: 'uint256',
},
{
name: 'amountOutMin',
type: 'uint256',
},
{
name: 'path',
type: 'address[]',
},
{
name: 'to',
type: 'address',
},
{
name: 'deadline',
type: 'uint256',
},
],
},
[
fromWei,
toWei,
// the problem
web3.eth.abi.encodeParameter('address[]', [
'0xC02aaA39b223FE8D0A0e5C4F27eAD9083C756Cc2',
'0x20fe562d797a42dcb3399062ae9546cd06f63280',
]),
getAddress(),
deadline,
]
)
From the error, it looks like encodeFunctionCall wasn't expecting an encoded array (at least, the way I did it). So how would I pass an array of addresses?
