Unable to upload cw20_base wasm file on terra-station

[Odelya]

I am trying to upload an optimized version of cw20_base contract to my localterra like this:

 const terra = new LCDClient({URL: 'http://localhost:1317', chainID: 'localterra',});
  const wallet = terra.wallet(mk);
  const storeCode = new MsgStoreCode(
    wallet.key.accAddress,
    fs.readFileSync('../artifacts/cs20_base.wasm').toString('base64'),
  );

  const storeCodeTx = await wallet.createAndSignTx({msgs: [storeCode]});

However, I am getting:

*code: 3, message: 'failed to execute message; message index: 0: Error calling the VM: Error during static Wasm validation: Wasm contract has unknown interfaceversion marker export (see https://github.com/CosmWasm/cosmwasm/blob/main/packages/vm/README.md): store wasm contract failed: invalid request',**

is it working with terra network? if so, how?

I checkout to tag v0.9.2 which depends on cosmwasm-std version = "0.16.0" and now it works. It could be related to that library. What do you suggest to do?

Terra is on CosmWasm 0.16 which means you’ll need to use branch 0.9.x

I am all new to this and have the same issue. Trying this example: https://github.com/terran6/nft-on-terra

My Cargo.toml file uses cw-plus v0.9.2 and CosmWasm 0.16.0. It looks like this: https://github.com/terran6/nft-on-terra/blob/master/contracts/cw721-metadata-onchain/Cargo.toml

Terra (both classic and terra2) are using cosmwasm 1.0 afaik. Closing this
