This is a minimal template you can fork to get started developing a Deku-C smart contract with Ligo.
You'll need to install Ligo, the Tuna compiler, and the Deku cli.
Additionally, our example frontend's dependencies requires npm.
If you have the Nix package manager, the provided flake has everything you need:
nix develop .
Our smart contract will be a simple counter lifted straight from the Ligo tutorials. Users can submit operations to increment, decrement, or reset an on-chain counter. The source is ./contract/main.jsligo.
On line 26 we define a simple test for the contract using Ligo's built-in test framework. We can run the test with the commmand:
ligo run test ./contract/main.jsligo
You'll see the following output indicating success:
- test_increment exited with value ().
Refer to the Ligo documentation for more on developing with Ligo, and don't hesitate to reach out!
We'll compile our Ligo contract to WebAssembly with the Tuna compiler:
ligo compile ./contract/main.jsligo | tunac > compiled.wat
Next, we'll deploy the contract to the Deku-C betanet.
First, we'll need to create an identity to use with the Deku-C network.
deku-c create-identity
By default, deku-c uses ~/.deku-c/identity.json.
Next, we can deploy the contract with an initial storage of 42:
deku-c deploy ./compiled.wat 42
This will output Dk1 address that uniquely identifies the new contract. Save this address for the next steps:
export CONTRACT_ADDRESS=<paste your Dk1 address>Let's check the current state of our contract:
deku-c get-storage $CURRENT_ADDRESS
Next, let's invoke an Increment command. We'll have Ligo compile
the parameter expression for us:
parameters=$(ligo compile parameter ./contract/main.jsligo "Increment (32)" )
deku-c invoke $CURRENT_ADDRESS $parameters
Our frontend is a simple React app that uses the deku-client library along with a Beacon-compatible Tezos wallet to interact with Deku-C.
(TODO: note about compatible wallets)
Install the dependencies for the frontend:
cd frontend
npm install
Make sure the CONTRACT_ADDRESS variable is still in the environment,
then start the development server:
npm run start
