Contract (simple.liq):

[%%version 1.0]

type storage = int

let%init storage = 0

let%entry main (parameter : int) storage =
  ( [], storage + parameter )

Deployment command:

liquidity --tezos-node http://alphanet-node.tzscan.io:80 --private-key <key> --protocol alphanet simple.liq --deploy

After I run this command I get the following error that I cannot make sense of:

Response Error:
in /chains/main/blocks/head/helpers/preapply/operations
- branch: proto.003-PsddFKi3.implicit.empty_implicit_contract

It seems that the node thinks that our implicit contract is empty.

    Looks like it's trying to use a mainnet node: proto.003-PsddFKi3 This refers to the proto 003 protocol that the mainnet runs, not the protocol for alphanet (which is PsddFKi32cMJ2qPjf43Qv5GDWLDPZb3T3bF6fLKiF5HtvHNU7aP)

  • @StephenAndrews perhaps this is a valid answer ?

  • @StephenAndrews I use the --protocol alphanet option, if that does not result in using the alphanet, then how should I do that?

    I don't know, I don't use liquidity - I'm just making an observation that the error being reported is from the mainnet protocol. @Ezy I don't think it's a valid answer, just a comment/observation - someone with experience with Liquidity should be able to answer.

You are using a private key which do not correspond to any account on the alphanet. It works with

liquidity --tezos-node http://alphanet-node.tzscan.io:80 --private-key edsk2j7Ka5nRzh2QkGCtcD1dFLbHYvYw7XAafWL3YEAQQ3Zd61NiqS --protocol alphanet simple.liq --deploy

Main contract Simple
New contract KT18bLbXyH5yMY9ShDfCwtiXegWHMTa4aS8H deployed in operation opENiYZ3xMTDu1hVdLi7kSU3cybucZrDnAUXznMgCr2twecAu9S

You can also deploy on the alphanet with http://www.liquidity-lang.org/edit/ which allows you to see the balance on your account and interact with deployed smart contract.
