Anchor is moving to a permanent home at otter-sec/anchor as we take over its stewardship.

Solana's ecosystem has been core to our work for years. Anchor has always been security-forward, and we're committed to keeping it that way for the developers who build on it.

@PolyNetwork2 was just compromised and hackers are stealing billions of tokens. Let's dive into what we know.

[OtterSec @osec_io]

Hackers were busy in May. These 3 exploits stood out 🦦🔎

1. Breaking a governance protocol
2. Draining $7.5M from a 3-week-old liquidity pool
3. Depegging a stablecoin

We compiled a few threads explaining what went wrong 🪡

I want to be a TOP smart contract auditor.

Solidity is a MUST HAVE, but building a strong foundation in EVM is crucial.

Starting this week, I'll be diving deep into the EVM.

Today, I'm sharing my ORDERED STEP-BY-STEP study plan. Join me, and let's tackle it together! 👇

We've seen more and more smart contract CTF challenges lately. These challenges are difficult to setup because they usually require private blockchain instances for players.
I wrote a guide on how to easily develop and host these challenges :D

All though this hack was comparatively low level compared to recent crypto hacks, I thought I would make a detailed analysis since it was not that well known.

This is my blog post describing the attack in depth:

On 18 June a ERC-777 smart contract specifically a UniswapV2Pair (SNOOD-WETH) contract was exploited and the entire liquidity present in that account was drained resulting in a loss of 104 eth.
