Dapp Example

This repository demonstrates how to call the Prosopo Protocol contract from within a second contract. The easiest way to use this contract in a development environment is via the integration repository. Manual build and deploy instructions are included below.

Prerequisites

Deploy the Prosopo contract

Follow instructions in Prosopo Protocol

Build and Deploy

Build and deploy the dapp-example contract with docker

The docker file is configured to use the substrate endpoint from the docker compose file. Change this endpoint and the docker compose file if you wish to deploy to a different node. Specify the Prosopo Protocol account as CONTRACT_ADDRESS.

CONTRACT_ADDRESS=5CCfRe5TxkUVMDMznbGs4wpxeWnUK8hC6dqQ7bZZtao6RFiH docker compose --file docker-compose.dapp.yml up dapp-build

Build and deploy the contract locally

After installing all substrate pre-requisites, in the contracts folder run:

cargo +nightly contract build

Then deploy the contract to a substrate node after populating the various arguments. For examples, of these arguments, please see the docker file.

Deploy via the Command Line

Use cargo contract.

$CONTRACT_ARGS = "$DAPP_CONTRACT_ARGS_INITIAL_SUPPLY $DAPP_CONTRACT_ARGS_FAUCET_AMOUNT $CONTRACT_ADDRESS $DAPP_CONTRACT_ARGS_HUMAN_THRESHOLD $DAPP_CONTRACT_ARGS_RECENCY_THRESHOLD"
cargo contract instantiate $WASM --args $CONTRACT_ARGS --constructor $CONSTRUCTOR --suri $SURI --value $ENDOWMENT --url '$ENDPOINT:$PORT' --gas 500000000000

Deploy via a User Interfacae

Use polkadot apps contract page.
