Contract compilation and deployment

1) Compile a contract example

The token contract can be found in SDK archive: examples/rust-example-token-contract. The following will compile it and generate an ABI for it:

cd examples/rust-example-token-contract
cargo partisia-contract build --release

Now you will find a .wasm-file in called token_contract.wasm in: /tmp/pbc-rust-wasm/examples/rust-example-token-contract/target/wasm32-unknown-unknown/release.
If you look at lib.rs file in your IDE, you will see the contract utilizes several functions denoted with the initial fn. Three of these functions are actions that allow you to perform the basic operations needed for a transfer. The functions are initialize, mint, and transfer. After deployment, you can call the functions from the dashboard. When you perform an action it changes the contract state. If you inspect the contract you can see the serialized data showing the contract state. Contract state can be revealed as a .json.

2) Upload the contract to the blockchain

To deploy a smart contract you need an account with gas to cover transaction costs. Open the wallet in the Dashboard or use Partisia Blockchain Explorer Select the token_contract.wasm and the token_contract.abi. In the total_supply field you put the number of tokens you want minted for total supply of the contract from the moment of deployment. The decimals field indicates placement of decimal point in total supply. E.g. total supply: 1050 decimals: 3 will mint supply of 1.050 token. After you send the contract to the chain a box appears below. You are provided with the following information fields Execution status, Hash, Invocation and Deployed at. Successful deployment will look like this:

deployment

You are now ready to interact with the contract. Copy the address of deployment and paste it into the menu Interact Wasm Contract in the dashboard. Now you can mint and transfer your tokens.

Congratulations! You have now created an active smart-contract on the Partisia Blockchain.
