How to deploy a smart contract¶
Quick guide to deploying a smart contract to VeChainThor blockchain:
Open VIDE in the Connex environment (visit https://vechainstore.com/ide)
A sample contract is available (ballot.sol), this contract is very basic. The goal is to quickly start to create and to interact with a smart contract on VeChainThor blockchain.

Compile contracts: in the
Compile tab click on
Start to compile button
Deploy contracts: in the
Run tab select the contract you want to deploy (eg Ballot), the constructor of Ballot contract needs a parameter is number of proposals (_numProposals: type uint8). Give any value and click on
“caption”: “VIDE: Run tab”
Running transactions: in the
Run tab after deploying a successful contract and confirmed, in the
Deployed Contracts table will appear the
Ballot contract and its address
Interacting with an instance
This new instance contains 4 actions which corresponds to the 4 functions (giveRightToVote, delegate, vote, winningProposal). Clicking on giveRightToVote, delegate or vote will create a new transaction.
giveRightToVote: Give $(toVoter) the right to vote on this ballot, may only be called by $(chairperson) is also the creator of the contract.
delegate: Delegate your vote to the voter $(to).
vote: Give a single vote to proposal $(toProposal).
winningProposal will not execute a transaction (blue action), not modify the state (variable value) of this instance.
winningProposal is constant you can see the return value just below the action.
