1st Solidity Gas Golfing Contest The Solidity Gas Golfing Contest was a competition for Solidity coders to produce the most gas-efficient code they can for a series of straightforward challenges. The 1st SGGC ran from 23 May to 30 June 2018. Each challenge is divided into "Standard" and "Wild" categories. Entries in the "Wild" category may use any Solidity language feature, while entries in the "Standard" category are prohibited from using inline assembly. The winner of each track received a 1 ether prize, sponsored by ChainSecurity and CryptoFin. Templates and documentation for each of the challenges, and test vectors to check code against, are at this truffle project and this embark project. Note that the test vectors used by the SGGC server are different from those provided.

Leaderboard To qualify for the leaderboard, an entrant must have submitted valid solutions for all five challenges. Their score is the sum of the gas used for their best submission for each challenge.
