Set up

Node >= 10.x && yarn > 1.x

$ node --version
v16.13.0

$ npm install --global yarn

$ yarn --version
1.22.17

Install dependencies

$ yarn

Test

1. Compile contract

$ yarn compile

2. Run tests

$ yarn test

Testnet deployment

1. BSC Testnet

PRIVATE_KEY=<admin-private-key> yarn deploy:bsctest

2. Create campaign for NFT721

PRIVATE_KEY=<manager-private-key> \
FACTORY721_ADDRESS=<factory-721-address> \
CAMPAIGN_ID=1 \
START_AT=1641543770 \
END_AT=1644135770 \
PAYMENT_TOKEN_ADDR=<erc20-address || address-zero>\
TOKEN_NAME=TESTTOKEN \
TOKEN_SYMBOL=TTK \
TOKEN_BASE_URI=<token-uri> \
  npx hardhat run --network testnet scripts/createCampaign721.ts

3. Create campaign for NFT1155

PRIVATE_KEY=<manager-private-key> \
FACTORY721_ADDRESS=<factory-1155-address> \
CAMPAIGN_ID=2 \
START_AT=1641543770 \
END_AT=1644135770 \
PAYMENT_TOKEN_ADDR=<erc20-address || address-zero>\
TOKEN_BASE_URI=<token-uri> \
  npx hardhat run --network testnet scripts/createCampaign1155.ts

Upgrade factory contracts

1. Clean cache and precompiled folders to avoid conflict errors

$ rm -rf artifacts cache .oppenzeppelin

2. Put your folder .oppenzeppelin into root directory
3. Update your smart contracts
4. Run upgrade via ProxyAdmin contract

$ yarn upgrade:bsctest

OR

$ yarn upgrade:bscmain

Solidity linter and prettiers

1. Run linter to analyze convention and security for smart contracts

$ yarn sol:linter

2. Format smart contracts

$ yarn sol:prettier

3. Format typescript scripts for unit tests, deployment and upgrade

$ yarn ts:prettier
