EVM Bytecode Optimisation

This repository contains the EVM bytecode optimisation for a Fibonacci function. Using opcodes from the Ethereum yellow paper, the challenge of this was to create a function to output the Fibonacci number at a given index using the shortest bytecode possible.

Constraints

• Input is a uint256 representing an index
• Return a uint256 representing the Fibonacci number

Contract source

High level code of the Fibonacci function: src/Contract.sol
