Staging repo for MakerDAO weekly executive spells.

$ git clone [email protected]:makerdao/spells-mainnet.git
$ dapp update

If the weekly executive needs to onboard a new collateral:

1. Update the onboardNewCollaterals() function in DssSpellCollateral.sol
2. Update the values in src/test/config.sol
3. Add onboardNewCollaterals(); in the actions() function in DssSpellAction

If the weekly executive needs to offboard collaterals:

1. Update the offboardCollaterals() function in DssSpellCollateral.sol
2. Update the values in src/test/config.sol
3. Add offboardCollaterals(); in the actions() function in DssSpellAction

$ make

Set ETH_RPC_URL to a Mainnet node.

$ export ETH_RPC_URL=<Mainnet URL>
$ make test

1. Install Rust.
2. Install Forge.

Set ETH_RPC_URL to a Mainnet node.

$ export ETH_RPC_URL=<Mainnet URL>
$ make test-forge

Set ETH_RPC_URL to a Mainnet node and ensure ETH_GAS is set to a high enough number to deploy the contract.

$ export ETH_RPC_URL=<Mainnet URL>
$ export ETH_GAS=5000000
$ export ETH_GAS_PRICE=$(seth --to-wei 100 "gwei")
$ make deploy

A few helpful tips to estimate gas. You can use the following to get a gas estimate for the deploy.

make all
make estimate

Once you have that, add another million gas as a buffer against out-of-gas errors. Set ETH_GAS to this value.

export ETH_GAS="$((<value from previous step> + 0))"
export ETH_GAS=$(bc <<< "$ETH_GAS + 1000000")

You should also check current gas prices on your favorite site (e.g. https://ethgasstation.info/) and put that gwei value in the ETH_GAS_PRICE line.

export ETH_GAS_PRICE=$(seth --to-wei 420 "gwei")

The process of verifying code on etherscan is a little bit more involved because of solc's weird behaviour around ABI Encoder v2.

1. Run make flatten
2. If your spell didn't use DssExecLib.addNewCollateral you need to tweak the flattened source.
   1. Remove pragma experimental ABIEncoderV2;
   2. Comment out DssExecLib.addNewCollateral method.
3. Go to etherscan and verify source.
   1. Add library: DssExecLib:0xfD88CeE74f7D78697775aBDAE53f9Da1559728E4
   2. Ensure optimizer is off and optimize runs = 200
