We are not gonna do the hard work instead of you.
You wants to learn, but you are too lazy to find the contract links?!

Open Etherscan and Coinmarketcap and start searching the contracts one by one. Most will be closed, but some are open...
Or ForkDelta - there is a link to every contract in top-left cell.

I already did the working of searching and going through smart contracts, but there is a chance that I might have missed the good example. Hence I am reaching out to the community to recommend the ones they found to be good.
