Deploy and call solidity contracts

This is an example repository that shows how to deploy and call solidity contracts on polkadot's pallet revive, using a regular polkadot node.

Getting Started

You will need bun installed in your system. Then run:

bun i
bun codegen

This will install the necessary packages and generate the contract's ABI, code and chain types.

It relies on:

• @parity/resolc to generate ABI+PVM from .sol.
• @wagmi/cli to generate the ABI types.
• viem to encode and decode function calls (fully typed).
• polkadot-api to connect and interact with revive pallet.

Usage

The contract source is 3_Ballot.sol. This is an example contract found in Remix https://remix.polkadot.io/, which puts some proposals up for voting and different accounts can vote them.

This repo has 3 scripts ready to interact with the contract:

• bun run deploy {dev account name}
  • Runs src/deploy.ts to deploy the contract.
  • For the account name you can put any string
  • e.g. bun run deploy Alice will deploy as Alice, but please use your own name, the script will guide you in case you need to set your account up.
  • Will give you a deployment address as a result
• bun winning {dev account name} {address}
  • Runs src/winning.ts to read from a view-only function and storage.
  • Gets the current winning proposal.
• bun vote {dev account name} {address} {vote: 0|1}
  • Runs src/vote.ts to call a contract function.
  • Votes for one of the proposals, indexed by 0 or 1.
