Gas Saver

\n\n**Gas Saver** is a collection of smart contracts to save gas on Ethereum.\n\n## How it works\n\nIt defines a modifier that you can use to wrap the methods where you want to save gas burning gas tokens.\n\nIt uses [Chi Gas tokens](https://medium.com/@1inch.exchange/everything-you-wanted-to-know-about-chi-gastoken-a1ba0ea55bf3) or\n[GST2 Gas Tokens](https://gastoken.io/)\n\n## Usage\n\nSimply add the modifier to the methods you want, specifying the `sponsor` that will pay part of the gas using Gas tokens. \n\nYou have to approve your contract to spend Gas tokens on sponsor behalf (i.e. call `approve`)\n\nBelow an example with CHI tokens\n\n```\nimport \"@emilianobonassi/gas-saver/ChiGasSaver.sol\";\n\ncontract MyContract is ChiGasSaver {\n\n...\n\nfunction myExpensiveMethod()\n external\n saveGas(msg.sender)\n returns (bool) {\n ...\n }\n...\n\n}\n```\n\nBelow an example with GST2 tokens\n\n```\nimport \"@emilianobonassi/gas-saver/ChiGasSaver.sol\";\n\ncontract MyContract is GST2GasSaver {\n\n...\n\nfunction myExpensiveMethod()\n external\n saveGas(msg.sender)\n returns (bool) {\n ...\n }\n...\n\n}\n```\n","readmeFilename":"README.md"}
