Gas Numbers Every Solidity Dev Should Know

Key:

⟢ Each box is = 2,000 units of gas. All numbers indicate the number of gas units each operation requires to execute.
⟢ Warm/Cold and Dirty/Clean is whether or not a slot or address has been accessed or written to within the current execution context.
⟢ New-Address is when a CALL is made to an address that does not exist, forcing a new account to be created in the state trie.

Opcode gas numbers were sourced from the official Ethereum Docs, and contract-calls were sourced from Etherscan.io and converted into gas units using Wolfram Alpha for calculations.

Inspired by Norvig's Latency Numbers, and a post in the Macro discord from a student named Justin Phu, who suggested someone make a version with gas numbers for popular calls and opcodes.
