export ETHERSCAN_API_KEY=
export L2_RPC=
export ETH_RPC_URL=$L2_RPC

PRIVATE_KEY=

ADDRESS=$(cast wallet address --private-key $PRIVATE_KEY)
BALANCE=$(cast balance $ADDRESS)
ETHER=$(cast --to-unit $BALANCE ether)

echo "$ADDRESS has $ETHER ether"

export L1_RPC=
export PRIVATE_KEY_DEPLOYER=$PRIVATE_KEY
