Store Code

For this tutorial, it is assumed that the fee collection address represents network ownership (why they get paid fees), thus they must be the uploader of the contract Wasm.

Copy the optimized Wasm file to the Provenance Blockchain project. From the tutorial project dir, run

shell
cp artifacts/tutorial.wasm $GOPATH/src/github.com/provenance-io/provenance

Then, from the provenance directory, store the optimized smart contract Wasm in the blockchain

shell
provenanced tx wasm store tutorial.wasm \\
    --instantiate-anyof-addresses "$feebucket" \\
    --from "$feebucket" \\
    --keyring-backend test \\
    --home build/run/provenanced \\
    --chain-id testing \\
    --gas auto \\
    --gas-prices="1905nhash" \\
	--gas-adjustment=1.5 \\
    --yes \\
    --testnet \\
	--output json | jq

To query the stored code (NOTE: The wasm module query commands only produces JSON output).

shell
provenanced query wasm list-code -o json | jq

Should produce output that resembles (field values may differ) the following.

json
{
  "code_infos": [
    {
      "code_id": "1",
      "creator": "tp1rj4s08a7va4rdwwk7zmwg90slz956qnjrfa5ta",
      "data_hash": "6B6D1579CF2FF09B197B521E74FDDF09429895FECFA5BDB5D779472FFBCA8CF8",
      "instantiate_permission": {
        "permission": "AnyOfAddresses",
        "address": "",
        "addresses": [
          "tp1rj4s08a7va4rdwwk7zmwg90slz956qnjrfa5ta"
        ]
      }
    }
  ],
  "pagination": {
    "next_key": null,
    "total": "0"
  }
}

The --instantiate-anyof-addresses flag is important when it is necessary to limit instance creation to specified accounts.

Copy the value of the id field. It is required to instantiate the contract in the next section.
