MahaLakshmi@mahalakshminadarDeployed a Smartcontract over Solidity's arithmetic operations with added overflow checks, on XinFin XDC Network under the injected web3 environment. Arithmetic operations in Solidity wrap on overflow. This can easily result in bugs, because programmers usually assume that an overflow raises an error, which is the standard behavior in high level programming languages. `SafeMath` restores this intuition by reverting the transaction when an operation overflows.The successful deployment link of XinFin: https://explorer.xinfin.network/tx/0x62a632f5b1379f432450b6c295adbb0c61d5a5d105130b4ed9eb97551900d8fd XinFinScan Block Explorer https://explorer.xinfin.network/tx/0x62a632f5b1379f432450b6c295adbb0c61d5a5d105130b4ed9eb97551900d8fd
