Terra MsgExecuteContract

[AlexBHarley]

I believe I should be able to use this library for constructing Terra compatible transactions instead of Terra.js or Anchor.js, is that correct?

If so, I need a little help creating a simple token transfer message, not too sure where things are going wrong when trying to transfer aUST tokens... Normal UST or LUNA transfers work great via the writer.sendTokens method, I guess I'm not fully understanding the WASM interaction.

import { coins } from '@cosmjs/amino';
import { cosmWasmTypes } from '@cosmjs/cosmwasm-stargate';
import { toUtf8 } from '@cosmjs/encoding';
import { AminoTypes, SigningStargateClient } from '@cosmjs/stargate';
import {
  MsgExecuteContract
} from 'cosmjs-types/cosmwasm/wasm/v1/tx';


async function main() {
  const writer = await SigningStargateClient.connectWithSigner(...);
  const from = '';
  const to = '';
  const contract = 'terra1hzh9vpxhsk8253se0vv5jj6etdvxu3nv8z07zu';
  const amount = '100000';

  const msg: MsgExecuteContract = {
    sender: from,
    contract,
    msg: toUtf8(
      JSON.stringify({
        transfer: {
          recipient: to,
          amount,
        },
      })
    ),
    funds: coins(parseInt(amount), 'aUST'),
  };

  const a = new AminoTypes({
    additions: cosmWasmTypes,
  });

  const aminoMsg = a.toAmino({
    typeUrl: '/cosmwasm.wasm.v1.MsgExecuteContract',
    value: msg,
  });

  const encoded = a.fromAmino(aminoMsg);
  console.log(await writer.signAndBroadcast(from, [encoded], {
    amount: [],
    gas: '100000',
  }));
}

The error I get back is Unregistered type url: /cosmwasm.wasm.v1.MsgExecuteContract, I believe this is because after poking around Terra a little I find that in their Codec file they register was/MsgExecuteContract, am I on the right track?

Unfortunately no. Terra decided to make all kinds of incompatible changes to CosmWasm (especially x/wasm) interfaces that are impossible to support for us. There might be cases where things work by accident, but it would be a frustrating experience overall. Also note Terra upgraded to Cosmos SDK 0.44 which CosmJS does not yet support but will probably do soonish.

[webmaster128]

Well, okay, one thing that could potentially work is 1. CosmJS support for SDK 0.44 and then 2. a Terra specific fork of @cosmjs/cosmwasm-stargate with all proto types generated from the Terra type definitions instead of using cosmjs-types. It would require significat talent and time but it can probably be done.

but I get this error : Log: unable to resolve type URL /cosmwasm.wasm.v1.MsgExecuteContract: tx parse error

Closing this, for Terra we just use Terra.js
