Solend auditing workshop slides.

A good read if you're developing smart contracts on @solana or other blockchains.

[Save (formerly Solend) @save_finance]

At 2021-08-19 12:40 GMT, an attacker attempted to exploit the Solend smart contract.

The attempt to steal funds was detected and stopped by the Solend team in time such that no funds were stolen.

@Sheldrake Oops, forgot to double-check those. All fixed again

I just saw A LOT of excitement about fast confirmations on newly deployed @Uniswap on @optimismPBC , but how does it really work, and can users trust them? Finally, isn't a single sequencer that provides such confirmations a threat to decentralization? Let's talk it through👇👇👇

Part two of my @DeribitInsights mini series on rollups is out!

The subject? Optimistic Rollup dispute resolution 🏛️

This (admittedly technical) piece builds on part one: https://t.co/ZOnUHO1MgV

For a non-technical intro to rollups, check out my primer: https://t.co/6yGTzaKzG0

i've been working on a new financial product: everlasting options

perps give traders never-ending futures exposure without the effort, risk, or cost of rolling

now, we can do the same for options... and @SBF_Alameda and I have a simple pricing model

[SBF @SBF_FTX]

In general, you can turn a future into a perp by having, by default, positions roll at the market price prior to expiration.

Super cool!

1/ It's high time for @optimismPBC vs @arbitrum. I know you've been waiting for it so let's go!🔥🔥🔥

Long 🧵

1/ As the @optimismPBC team has dropped news that their mainnet launch has been brought forward, I thought it would be useful to go through what the Optimism ETH Layer 2 solution is, how it works, and what it means for #Ethereum...

[Rhino.fi @rhinofi]

The Ξthereum Layer-2 ecosystem is in supersonic (ultrasound 🦇 🔊) mode and keeps growing exponentially!

Congrats to all the awesome builders out there!

Who are we missing!?

[Uniswap @Uniswap]

🦄 We are thrilled to announce that Uniswap v3 is now live on Ethereum mainnet!

https://t.co/liqYXtQoM2 has been updated to support v3.

[Haseeb ＞|＜ @hosseeb]

🦄 Uniswap v3 just dropped.

It contains some huge ideas—I remember hearing about them from Hayden back in early 2020. Now they’re finally public!

These are my first reactions for the effects v3 will have on Uniswap's future. Rough takes right now, but here's a thread. 👇

🚨 Smart Contract Bug found in Pancake V2 🚨

🐛: Pancake new router is incompatible with Pancake LP implementation.

Users may get __revert__ txs upon __swaps__ due to the bug.

Vulnerability was reported to @PancakeSwap team asap.

Thread below 👇

[Anton Cheng @antonttc]

First time sharing at a meetup, awkward but fun.

[Kris Kaczor 🦆⚡️ @krzKaczor]

We are all DYING to switch to Layer 2🔥There are lots of promising scaling solutions for Ethereum out there but it's easy to get lost in the hype. That's one of the reasons why we've created L2Beat - analytics for layer 2.

Check it out 👉 https://t.co/uYkcqUiG0i and read on 🧵

[ping.eth @PingChenTW]

Given a transaction only pays miner gas fee when it is not reverted, then no one will need to pay $80 for a failed token swap anymore.

So...about that Furucombo exploit...wanna know how it works?

Let's work backward from one of the fund-stealing TXes: https://t.co/Q07ZXxoAVu

Attached pic is its execution trace (shoutout to https://t.co/wQFTcaAZIm). Notice the nested delegatecalls.

[FURUCOMBO @furucombo]

Today at 4:47 PM UTC the Furucombo proxy was compromised by an attacker. We have deauthorized the relevant components and believe the vulnerability to be patched but we recommend users remove approvals out of an abundance of caution.
