SotN#19: HARDENING! with Demian Brener from Open Zeppelin (Harvest Hack, Defining Trustless, New Open Zeppelin Platform: DEFENDER)
Starting with the Harvest Hack! We discuss how the Harvest Hack happened.

Daily Gwei account of the Harvest Hack https://thedailygwei.substack.com/p/a-rotten-harvest-the-daily-gwei-103
Was this a new type of exploit? Or have we seen this type of exploit before?
What was the weakness in Harvest’s protocol that enabled this exploit?
Was this exploit avoidable, or was that attack surface integral to how harvest operated?
What should the Harvest team have done differently?
Defining ‘Trustless’
John Adler defines trustless as these two things
1. You always have your money
2. No one can steal your money Do you agree with this definition of trustless? How would you define trustless?
New Open Zeppelin Platform: DEFENDER

| 0:00.0 | One of the tools I've started to use recently is zapper. For those of you that were a part of the |
| 0:04.5 | 2017 bull market, it was characterized by just opening up block folio and refreshing it over and |
| 0:09.4 | over and over again. And also, anytime you ever made a trade, you would have to go into block folio |
| 0:14.1 | and manually input that trade information to make sure that your portfolio that you think that |
| 0:18.9 | you have matches what you actually have. With zapper, you don't have to do any of that anymore, |
| 0:23.9 | because all you have to do is zapper is input your Ethereum addresses, and then zapper will give you |
| 0:29.6 | a really elegant report as to where all your money is. So there will never ever be any disconnect |
| 0:35.5 | between the money that you think that you have and the money that zapper reports to you. |
| 0:39.9 | Zapper looks directly on chain and gives you a nice portfolio summary of all your assets and |
| 0:45.2 | how many assets and all of your debt and all of your lending positions, all of your positions, |
| 0:50.0 | all at once. So there's no more editing your portfolio because zapper just does it for you. |
| 0:55.7 | One thing that I thought was really useful about zapper was when I plugged my wallets in, |
| 0:59.9 | I found that I had submitted liquidity to Uniswap forever ago, and without zapper, |
| 1:04.3 | I would have probably lost that forever because zapper knows where your money is better than you do. |
| 1:09.0 | It's also the gateway to investing your money into this ever-expanding list of available |
| 1:13.6 | DeFi platforms like Curve, Balancer, Uniswap, Yurn. In the bankless nation, there is this growing |
| 1:20.0 | number of money legos and keeping track of them all is just super overwhelming, which is why |
| 1:24.8 | you can just go to zapper and zapper will solve the problem of there just being too many money |
| 1:29.7 | legos to choose from. So check them out at zapper.fi, enter your Ethereum addresses and check out your |
| 1:35.7 | portfolio and see if there's anything that you missed. Your Ethereum address is a bankless bank |
| 1:41.6 | account, but here's the problem. It doesn't have a human readable name. It's represented by this |
| 1:46.2 | long hexadecimal string that no one can read. Unstoppable domains has the solution to that problem. |
