Refer to the veOGV site for an overview of the project.

Install Foundry following the instructions here.

Run:

forge install

• EOA wallet
  • You'll need an EOA wallet with enough ETH to create contracts and make a few transactions.
  • The wallet is referred as the "deployer" in the instructions below.
• Governance token
  • Edit contracts/GovernanceToken.sol to set the name and symbol of your governance token
• Staking token
  • Edit contracts/OgvStaking.sol to set the name and symbol of your staking token
  • Pick configuration values to be used during the deployment phase
    • epoch: date at which users can start staking, as a Unix timestamp. For example to have the staking start on Tue Jul 12 2022 00:00:00 GMT+0000, use an eopch value of 1657584000
    • min_stake_duration: minimum staking duration, in seconds. For example for to have a minimum of 6 months, use a value of 15552000 = 6 * 30 * 24 * 60 * 60.
• Rewards
  • Pick configuration values to be used during the deployment phase -inflation_slopes: An array of structs (time_start, time_end, rate_per_day) with times in seconds since staking epoch and rate as an OGV amount with 18 decimals. The time ranges should be contiguous meaning the end_time for a range should be used as start_time for the next range.

The contracts can be deployed either using a script or manually via the forge cli. It is recommended to use the script as it is less error prone.

Update the deploy script with your desired values for epoch, min_stake_duration and inflation_slopes.

Define the following environment variables in your shell:

export DEPLOYER_ADDRESS=...
export DEPLOYER_PRIVATE_KEY=...
export ETHERSCAN_API_KEY=...

Make sure you have enough ETH to pay for gas in the DEPLOYER wallet.

Run the script on Goerli first:

forge script contracts/deploy/script.s.sol:Deploy --rpc-url <goerli_rpc_url> --broadcast --verify -vvvv

Run the script on Mainnet:

forge script contracts/deploy/script.s.sol:Deploy --rpc-url <mainner_rpc_url> --broadcast --verify -vvvv

Notes:

• The exact same set of commands can be used on Testnet and Mainnet. Just update the <rpc_url> to point at the desired target network.
• The commands below are for deployig with proxies that give the optionality to upgrade the implementations in the future.

Deploy the implementation

forge create contracts/GovernanceToken.sol:OriginDollarGovernance \
    --rpc-url <rpc_url> \
    --private-key <deployer_private_key> \
    --etherscan-api-key <your_etherscan_api_key> \
    --verify

Deploy the proxy, then set the implementation. Note the second constructor argument is the 4-byte encoded signature of the initialize() function.

forge create contracts/upgrades/ERC1967Proxy.sol:ERC1967Proxy \
    --constructor-args <ogv_implementation_address> 0x8129fc1c \
    --rpc-url <rpc_url> \
    --private-key <deployer_private_key> \
    --etherscan-api-key <your_etherscan_api_key> \
    --verify

Deploy the implementation, including setting immutable variables via the constructor.

forge create contracts/RewardsSource.sol:RewardsSource \
    --constructor-args <ogv_proxy_address>
    --rpc-url <rpc_url> \
    --private-key <deployer_private_key> \
    --etherscan-api-key <your_etherscan_api_key> \
    --verify

Deploy the proxy, then set the implementation and owner

forge create contracts/upgrades/RewardsSourceProxy.sol:RewardsSourceProxy \
    --rpc-url <rpc_url> \
    --private-key <deployer_private_key> \
    --etherscan-api-key <your_etherscan_api_key> \
    --verify

cast send <rewards_source_proxy_address> \
    "initialize(address,address,bytes)" <rewards_implementation_address> <deployer_address> ''\
    --rpc-url <rpc_url> \
    --private-key <deployer_private_key>

Deploy the implementation, including setting immutable variables via the constructor.

forge create contracts/OgvStaking.sol:OgvStaking \
    --constructor-args <ogv_proxy_address> <epoch> <min_stake_duration> <rewards_proxy_address> \
    --rpc-url <rpc_url> \
    --private-key <deployer_private_key> \
    --etherscan-api-key <your_etherscan_api_key> \
    --verify

Deploy the proxy, then set the implementation and owner

forge create contracts/upgrades/OgvStakingProxy.sol:OgvStakingProxy \
    --rpc-url <rpc_url> \
    --private-key <deployer_private_key> \
    --etherscan-api-key <your_etherscan_api_key> \
    --verify

cast send <rewards_source_proxy_address> \
    "initialize(address,address,bytes)" <ogv_implementation_address> <deployer_address> ''\
    --rpc-url <rpc_url> \
    --private-key <deployer_private_key>

Set the target as the veOGC contract

cast send <rewards_source_proxy_address> \
    "setRewardsTarget(address)" <staking_proxy_address> \
    --rpc-url <rpc_url> \
    --private-key <deployer_private_key>

Set the inflation slopes

cast send <rewards_source_proxy_address> \
    setInflation((uint64,uint64,uint256)[])" <slopes> \
    --rpc-url <rpc_url> \
    --private-key <deployer_private_key>

Note the cast syntax for passing an array of structs as an argument is "[(x1,x2,x3),(y1,y2,y3),...)]". For example:

cast send 0x14418a3e84f8e6ED4dAfea481E7579673Cd5ed20 \
    "setInflation((uint64,uint64,uint256)[])" "[(1673504668,1704608668,100000000000000000000000),(1704608668,1735712668,1000000000000000000000)]" \
   --rpc-url $RPC_URL \
   --private-key $DEPLOYER_PK

Perform some tests in a fork to verify the contracts were properly deployed and configured.

TODO FILL IN INSTRUCTIONS TO START A FORK AND RUN SOME VERIFICATION TESTS

As a security measure, it is strongly recommended to have the contracts owned by a multi-sig vs an EOA. After having verified the deployment ran as expected, use the following procedure to transfer ownership of the contracts from the deployer EOA to a multi-sig.
