Impact

CRITICAL! Almost all USDC liquidity on the REKT/USDC uniswap pool can be stolen, due to an authorization issue with burnFrom() on the REKT token.

Background

Uniswap v2 pools get the prices for their swaps by comparing the relative amounts of each of the two tokens that they hold. If the pool holds very little of token A, and a lot of token B, then it only takes a little of token A to buy a lot of token B.

Currently REKT and USDC are fairly priced in the pool. If there were to suddenly be very little REKT in the pool, but the same amount of USDC, then very little REKT would be able to buy a lot of USDC.

Install AWX-operator on Ubuntu 20 using Minikube

I’ve had a few requests for this demo as It seems like a lot of people are having issues setting up the new version of AWX. Before v18, (v17) you could simply install AWX on a server with enough resources. Now, the preferred way to install AWX is via the AWX-operator. So you need a Kubernetes or OpenShift cluster. For this demo, I’m using Minikube.

(if you get any errors, check the bottom of this page for the fix)

I’m using minikube because it’s a single node cluster and it keeps the price down. I did try this on a t2.medium, but there just weren’t enough resources to get it working.

This demo will cover the following:
