Deploying the Application

The first step to deploy your application is to configure a wallet. This will determine where the application will be deployed: either to a local net or to the public deployment (i.e. a devnet or a testnet).

Local network

To configure the local network, follow the steps in the Getting Started section.

Afterwards, the LINERA_WALLET, LINERA_STORAGE, LINERA_KEYSTORE environment variables should be set and can be used in the publish-and-create command to deploy the application while also specifying:

1. The location of the contract bytecode
2. The location of the service bytecode
3. The JSON encoded initialization arguments

linera publish-and-create \
  target/wasm32-unknown-unknown/release/my_counter_{contract,service}.wasm \
  --json-argument "42"

Devnets and Testnets

To configure the wallet for the current testnet while creating a new microchain, the following command can be used:

linera wallet init --faucet https://faucet.{{#include ../../RELEASE_DOMAIN}}.linera.net
linera wallet request-chain --faucet https://faucet.{{#include ../../RELEASE_DOMAIN}}.linera.net

The Faucet will provide the new chain with some tokens, which can then be used to deploy the application with the publish-and-create command. It requires specifying:

1. The location of the contract bytecode
2. The location of the service bytecode
3. The JSON encoded initialization arguments

linera publish-and-create \
  target/wasm32-unknown-unknown/release/my_counter_{contract,service}.wasm \
  --json-argument "42"

Interacting with the application

To interact with the deployed application, a node service must be used.
