Today we are at the horizon of the events where Metaverse and DeFi touch

Say hello to WrapX

Supercharge your NFTs and add new actions to them while keeping their integrity and value

Read the (love) story of #meebit 7497 and its desire of getting a @CryptoKitties 🤖💕🐱

🧵👇
1/9 There was a Meebit that wanted a CryptoKitty but could not buy it because the Meebit could neither hold any fund nor interact with any protocol.
2/9

So the Meebit wrapped itself using WrapXSet, a wrapper that give it NFTSet-like functionalities such as holding funds and execute any tx

3/9

The Meebit asked 0.2 ETH to its original owner and was able to receive it thanks to its new super powers

Then, it was unsure to use ETH directly since it deeply believes in Ethereum

So it opened a debt position on @compoundfinance for 50 DAI

4/9

Anyway, the Meebit could not get its beloved cat because ETH was the only currency accepted.

So it interacted with @Uniswap to swap its DAI for ETH

etherscan.io/tx/0x413fe7a04…
5/9

Finally, the Meebit went to the CryptoKitties Sales Auction Contract and bought its beloved cat leveraging exploiting its new wrapper capabilities (WrapXSet) that not only allows it to receive funds but also other NFTs!

6/9

What’s the story here? Wrapping is a powerful concept that can be applied to bring composability and interactions to NFTs maintaining, if properly designed (i.e., wrap/unwrap mechanisms), the integrity and the values of the wrapped NFTs

But more importantly…
7/9

NFTs exist outside any chain, smart contracts are just projections/forms/slices which sometimes are limiting their full potential!

This means that wrappers allow multiple legitimate representations of NFTs

Wrappers are means to supercharge NFT actions and capabilities
8/9

WrapX is the project which collects these wrappers and because it's DeFi they are composable you can wrap the wrapper and get the sum of the superpowers!

9/9

Phase 2 completed

Most of the concepts are on the table for the project I am working on for @ETHLisbon (the last phase, phase 3 will be in Lisbon)

Stay tuned, some of you will receive an invite for the alpha release 😎

1/Y A thread on how you can leverage @iearnfinance not only as a yield source provider but also as a very powerful (and simple) framework to develop creative strategies.

A pegging mechanism which uses yield to peg @proofofhumanity $UBI to a target supply via a meta-vault

More👇
2/Y Few weeks ago @ryantcwynar @rudygt and @santisiri pinged me on brainstorm about how to use yield to burn @proofofhumanity $ubi so they can keep the supply stable

3/Y @proofofhumanity is a project which tries to solve challenges on digital identity developing a sybil resistant protocol, by @Kleros_io and @DemocracyEarth

TL;DR you verify your identity and mint $UBI, so supply increase for every human verified

Taking a look...

ethtx.info/mainnet/0x8bb8…

This is the second attack whish uses multiple flash liquidity,
flash swaps via Uniswap and flash loans via dYdX

We will see very complex things via @AaveAave V2 batch flash loans :)
Quite interesting the attacker asked 3 loans via flash swaps to 3 different pools on Uniswap

WETH-WBTC 90k
WETH-USDC 82k
WETH-USDT 96k

It's definitely a batch flash loan via flash swaps!

And this is just the beginning...
And other two loans from dYdX

76k ETH and 2.9m DAI

continuing...

Evil jars deployed during the attack and passed in the swapExactJarForJar, investigating more on this

etherscan.io/address/0x75aa…

etherscan.io/address/0x02c8…

The are sensible ops executed in that method (e.g. approve, withdraw etc).
In addition in the second invocation for swapExactJarForJar there were passed a target and doing a delegate call to CurveProxyPool 😢

Really complex and is not using at all FlashLoans!
