Local Deployment

start the local testnet by anvil at localhost:8545:

# produces a new block every 1 second
anvil --block-time 1

deploy the staking v0.1 contract:

# use 0xf39Fd6e51aad88F6F4ce6aB8827279cffFb92266 as sender
forge script script/StakingLocalTest.s.sol:StakingLocalTestScript --optimize --fork-url http://localhost:8545 --broadcast

interact with the contarcts by cast:

# Arpa token address 0x5fbdb2315678afecb367f032d93f642f64180aa3
# Staking address 0xe7f1725e7734ce288f8367e1bb143e90bb3f0512

# address 0xf39Fd6e51aad88F6F4ce6aB8827279cffFb92266
# (private key: 0xAC0974BEC39A17E36BA4A6B4D238FF944BACB478CBED5EFCAE784D7BF4F2FF80)
# will have 1e10 Arpa

# Two nodes have been added into operators whitelist.
# Their private keys and addresses can be found in .env

# to check the Arpa balance
cast call 0x5fbdb2315678afecb367f032d93f642f64180aa3 \
"balanceOf(address)(uint256)" 0xf39Fd6e51aad88F6F4ce6aB8827279cffFb92266

# to mint more Arpa for any address
cast send 0x5fbdb2315678afecb367f032d93f642f64180aa3 \
"mint(address,uint256)" ANY_ADDRESS ANY_AMOUNT \
--private-key 0xAC0974BEC39A17E36BA4A6B4D238FF944BACB478CBED5EFCAE784D7BF4F2FF80

# to check the owner of deployed staking contract
cast call 0xe7f1725e7734ce288f8367e1bb143e90bb3f0512 "owner()(address)"

# to start the pool with 1,500,000 Arpa reward and 30 days
cast send 0xe7f1725e7734ce288f8367e1bb143e90bb3f0512 "start(uint256,uint256)" 1500000000000000000000000 2592000 \
--private-key 0xAC0974BEC39A17E36BA4A6B4D238FF944BACB478CBED5EFCAE784D7BF4F2FF80
