GasToken.io
GasToken is a new, cutting-edge Ethereum contract that allows users to tokenize gas on the Ethereum network, storing gas when it is cheap and using / deploying this gas when it is expensive. Using GasToken can subsidize high gas prices on transactions to do everything from arbitraging decentralized exchanges to buying into ICOs early. GasToken is also the first contract on the Ethereum network that allows users to buy and sell gas directly, enabling long-term "banking" of gas that can help shield users from rising gas prices.
