yearn-protocol VS harvest-strategy

Well, I would be way off my knowledge comfort zone since I personally cannot absorb ETH gas fees in DeFi. So I cannot help you more than that. I believe YearnFinance is one of the well respected DeFi solution on Ethereum, and probably the place I would start with.

Also interested in any kind of robot auto-investment of ETH, some system where you deposit funds and they are managed on your behalf following the market and trends. I *think* this is what https://yearn.finance is trying to do, but they are in beta. Has anyone built a fully operational and proven auto ETH investment platform?

The latter is how you see big yields that wouldn't make much sense otherwise. The thing is that the value of those governance tokens can fluctuate a LOT more than your base assets, so unless you sell them immediately, your rewards could lose value. That's where yield aggregators (also known as auto-compounders) like yearn.finance come in. They automatically convert the rewards back into the base assets so that you don't have to hold those governance tokens.

Seriously. If we've learnt anything from other hypes like yearn.finance last year it's this:

check this link for some of the yields, u can get on yearn.finance. theirs other ones but this ones pretty straight forward to use

I recently put some $WFTM in beta.yearn.finance, to then take the $yvWFTM to abracadabra. All went well. Today I wanted to put in more wFTM into that same yearn vault. After doing so, I can't seem to locate the receipt token. Anyone have any idea where to find it? It's not in my Metamask and I can't find it on yearn.finance either...

yearn.finance is a DeFi yield-farming aggregator service. This means that the protocol finds the best yields across platforms like Aave, Compound, and dYdX, mostly across Ethereum, to earn in-kind yields based on the aforementioned protocols.

During one of their AMA's a while back Alex mentioned that the reason Celsius' rates are so high is because they use all the defi apps like AAVE, Compound, etc and switch amongst them to get the best rates. Never really questioned that answer too much, but today I was looking at yearn.finance and that is what they claim to do (aggregate other defi rates and switch to the best one), but yearn is offering between 2% and 4%. Most defi apps like curve also offer around 2.5% or so on stablecoins. Just wondering how Celsius is able to offer 8.88% yield (and BlockFi is able to offer 8.25%), which is more than twice any rates I was able to find on defi? Still learning here so forgive me if I am missing something.

In terms of DeFi codebases I'd recommend that you read the code of a project you're already familiar with. That way you know what to expect. Good codebases IMHO are the Curve one (written in Vyper and well documented), Harvest strategies and yearn strategies: - https://github.com/curvefi/curve-contract - https://github.com/harvest-finance/harvest-strategy - https://github.com/yearn/yearn-protocol

You can e.g. start with yEarn and Harvest. Their strategies repos are here: - https://github.com/yearn/yearn-protocol - https://github.com/harvest-finance/harvest-strategy
