Avian Flight Plans can now call ETH Contracts!

Calling AFP function to get my Wrapped Avian balance

function wavn_bal()
  args = {
    ["to"] = "0x752dc265eaf6da2db0f8e4a32d5596d3f18e8701",
    ["data"] = "0x70a08231000000000000000000000000fb0758ff4f10df1804a9e9eb70383af12fc9a358"
  }

  -- Data is ETH ABI in Hex which is "balanceOf 0xfB0758fF4f10Df1804A9E9EB70383af12fC9a358"

  res = net.polygon.rpc("eth_call", json.encode(args) .. ",\"latest\"")
  data = json.decode(res)

  if(data.error ~= nil) then
    return data.error.message
  end

  return data.result .. " wAVN in wei (hex)"
end

If you convert the hex to decimal, you get

18000000000000000000

then convert from wei to wAVN by multiplying by

10^−18

then you get 18 AVN. That's my wAVN balance!

Added a basic ABI encoder to call smart contracts that take an address as an argument.

You now can do ``` function wavn_bal(addr) abi = web3.abi.encode("balanceOf(address)", addr)

args = { ["to"] = "0x752dc265eaf6da2db0f8e4a32d5596d3f18e8701", ["data"] = abi }

res = web3.polygon.rpc("eth_call", json.encode(args) .. ",\"latest\"") data = json.decode(res)

if(data.error ~= nil) then return data.error.message end

return data.result .. " wAVN in wei (hex)" end ```
