Nice tips. I think it would be great if you can show all of these tips in a real DAPP example.

See uni v2 actual code

Is it recommended to use the Remix IDE's optimization feature?

[@EatTheBlocks]

If you deploy to production.

[@despareint]

@@EatTheBlocks Some are suggesting to turn it off (Remix optimization) in production. So I'm a bit confused at this point.

[@EatTheBlocks]

@@despareint why are they suggesting this? You want code that is gas optimized for production.

@@EatTheBlocks It used to have problems, i think in solidity 0.5.0, so people still think this is the same

you're awesome man really

[@EatTheBlocks]

Your optimizer settings are wrong at 3:46 Optimizer settings should be under under settings, as in: compilers.solc.settings.optimizer:{...}

[@nikolais6452]

Only if you are not using a EVM framework, like truffle, hardhat or forge

I have a doubt...after deployment of a contract on to a test network, first time deployment is successful and then after when I did deploy again on the test network it said transaction may fail exceeded gas limit, VM execution error

[@EatTheBlocks]

its possible, gas requirements change depending on whats in the storage of the smart contract the and input provided to the function.

[@bikashjena8167]

@@EatTheBlocks Thanks for the reply.. How can I solve this error.. because I am preparing a contract that will store Blacklisted IP address... It consists of both IPv4 and IPv6 types of addresses.

[@EatTheBlocks]

@@bikashjena8167 increase gas limit on your transaction
