For Testing In Prod (Mainnet).\n\n## Overview\n\nA gas efficient ERC721 contract that allows the `OWNER` to recover gas costs.\n\nDeployed to Mainnet at [`0x9172c52bf412de76e080bd595f8f8c55f0ff867c`](https://etherscan.io/address/0x9172c52bf412de76e080bd595f8f8c55f0ff867c).\n\nDeployed to Rinkeby at [`0x715da5e53526bedac9bd96e8fdb7efb185d1b6ca`](https://rinkeby.etherscan.io/address/0x715da5e53526bedac9bd96e8fdb7efb185d1b6ca).\n\nDeployer: [`0xc9ab63915c6738c8ce5ca245979203bfa3f2499f`](https://etherscan.io/address/0xc9ab63915c6738c8ce5ca245979203bfa3f2499f).\n\n#### Known Errors\n\nHardhat issue:\n```sh\nError HH12: Trying to use a non-local installation of Hardhat, which is not supported.\nPlease install Hardhat locally using npm or Yarn, and try again.\n```\n\n\u003e Make sure hardhat is installed by running `yarn` or manually adding hardhat to dev dependencies using `yarn add --dev hardhat`.\n\n\n\n\n## Blueprint\n\n```ml\nlib\n├─ ds-test — https://github.com/dapphub/ds-test\n├─ forge-std —

[instructions](https://github.com/gakonst/foundry/blob/master/README.md#installation).\n\nDon't have [rust](https://www.rust-lang.org/tools/install) installed?\nRun\n```bash\ncurl --proto '=https' --tlsv1.2 -sSf https://sh.rustup.rs | sh\n```\n\nThen, install the [foundry](https://github.com/gakonst/foundry) toolchain installer (`foundryup`) with:\n```bash\ncurl -L https://foundry.paradigm.xyz | bash\n```\n\nNow that you've installed the `foundryup` binary,\nanytime you need to get the latest `forge` or `cast` binaries,\nyou can run `foundryup`.\n\nSo, simply execute:\n```bash\nfoundryup\n```\n\n🎉 Foundry is installed! 🎉\n\n#### Configure Foundry\n\nUsing [foundry.toml](./foundry.toml), Foundry is easily configurable.\n\n#### Install DappTools\n\nInstall DappTools using their [installation guide](https://github.com/dapphub/dapptools#installation).\n\n#### Setup\n\n```bash\nmake\n# OR #\nmake setup\n```\n\n#### Build\n\n```bash\nmake build\n```\n\n#### Run Tests\n\n```bash\nmake test\n```\n\n## License\n\n[AGPL-3.0-only](https://github.com/abigger87/boomerang/blob/master/LICENSE)\n\n# Acknowledgements\n\n-
