GasToken (https://gastoken.io)
GasToken is an Ethereum ERC20 smart contract that lets users tokenize gas, an internal resource used in Ethereum to pay for transactions. The idea is simple: store gas when gas prices are low, release it when gas prices are high and experience lower transaction fees. GasTokens can be traded like any other ERC20 token.
The details on how GasToken works can be found here: https://gastoken.io
This repository contains the Solidity code for two GasToken variants (GST1 and GST2) and exhaustive test suites of those contracts' functionalities. The contract/ folder contains our smart contracts, the test/ folder contains our pyethereum.tester based test suite.
Deployments
The contracts are deployed on Ethereum, Kovan (testnet), Rinkeby (testnet), Ropsten Revived (testnet), and Ethereum Classic.

Ethereum Classic
The GST2 code deployed on Ethereum Classic slightly differs from that on Ethereum and the testnets. For details, check out contract/GST2_ETC.sol
Dependencies
The code was tested using python 3.6.2 and Solidity Version: 0.4.18+commit.9cf6e910.Darwin.appleclang
