Staging repo for MakerDAO weekly executive spells.
$ git clone git@github.com:makerdao/spells-mainnet.git
$ dapp update
$ make
Set ETH_RPC_URL to a Mainnet node.
$ export ETH_RPC_URL=<Mainnet URL>
$ make test
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. Once you have that, add another million gas as a buffer against out-of-gas errors. Feed this value back into ETH_GAS.
SOLC_FLAGS="--optimize --optimize-runs=1" dapp --use solc:0.5.12 build --extract
seth estimate --create $(cat ./out/DssSpell.bin) 'DssSpell()'
export ETH_GAS="$(($ETH_GAS + 0))"
export ETH_GAS=$(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")
