DeFi I got more hours on etherscan that you got on your favorite video game DMs open for onchain investigation requests.

Do you want to become an on-chain detective?
Read this then
I learned all of this in the past year and I decided to share some of my knowledge
This should teach you how to analyze an ethereum address from scratch

I am not
@zachxbt
but if you know of some onchain activity that is worth investigating, dm me.
I learned a fair share about onchain tracking in the last 2+ years and I would like to spend some % of my time helping people out.

Euler Finance situation getting interesting as the exploiter received an encrypted message from the Ronin Bridge Exploiter - which is believed to be Lazarus - DPRK hacking group.

To get a better understanding of the wallet you can also look to use tools like
@AppBreadcrumbs
to visualize connections
To understand what happens in one particular tx, go check
@TenderlyApp
. They even allow you to simulate your transactions at a given block

Start with etherscan
Learn about how to use etherscan, provides a ton of tools and a cool overview of what is possible to do can be found in this thread:
Need real-time alpha?
Look no further than Etherscan. It is your best friend.
This thread will teach you how to master it. (1/x)

To follow up on my thread about how to become an on-chain detective, I decided to write a simple step by step tutorial on how to scrape all the DEX trades of a particular wallet.
It should give you everything you need to start digging on your own.

For python you can use , install it and then you simply import the library:
from etherscan import Etherscan

Things I would look for:
Is the address a smart contract, multisig or just a wallet?
What tokens does it hold?
What addresses does it interact with?
What do these interactions look like?
Any DEX activity?
Flashbots usage/private transactions?

Once you learn a bit you can start analyzing any wallet just by looking into its on-chain activity
If the wallet is not very active it might be enough to just use etherscan and you can stop after this step

It might not surprise you that there is some wash trading happening on
@HuobiGlobal
. Besides they have a history of doing so.
What might surprise you is the extend of it.
~2 weeks ago, Huobi started wash trading on basically ALL altcoin pairs.

Thinking about starting a discord to connect voluntary onchain detectives. The purpose would be to dig into different DeFi projects and find if they work as they should, if someone abuses them etc.
With the lack of regulations, the results could be published and have real impact

Now seriously, man has been slow rugging since april and has the audacity to come up with a new 'stable' coin. Where did we see that playbook? (

A lot has been written about this, here is a tldr:
Two things:
- I will launch a new stable coin
- There's gonna be a $USDN situation resolution plan set in motion before.

You maybe saw this thread by light and now you see USDD at .97 and you might be thinking that Justin Sun would be risking too much to let it fail and therefore be tempted to buy either USDD or TRX.
But there are many reasons why you should stay away from it, let's dive in.
and so one of the greatest exit pumps of this year ($550mm in USDC/USDT borrowed and realized as profit through Vires using a parabolic WAVES that later imploded as collateral) is unwound:
and just like CLAMS on Poloniex, naive lenders got hosed.

42 min ago, the Kyberswap exploiter sent the team another message:

For this part we will use python/etherscan API and infura
First create an account on etherscan
Next go to API keys and generate your API key
Etherscan free plan gives you up to 3 API keys with up to 5 calls/sec

Few observations from today:
- Ct is bigger than I thought
- Many people call the Kyberswap chad, based etc., his behaviour is in fact childish and cruel - not something to be celebrated.
- This industry is wild and I cannot imagine doing something else now.

To analyze activity of a particular address we can start with scrapping all the tx's and token transfers. For that we can use:
eth.get_normal_txs_by_address(address, startblock, endblock, sort)
eth.get_erc20_token_transfer_events_by_address(address, startblock, endblock, sort)

Often there is too much information to be checked manually on etherscan and you wouldn't be able to get everything you need just by checking etherscan
Once you get some sense of what type of wallet and activity are you looking at, it is a time to start scrapping for more depth

Jump's decisions harmed many of us and I think they should have done better.
First they create a precedent by bailing out
@wormholecrypto
with 120 k eth in <12 hours.
They showed the world that their size is size.
I don’t know exactly what to say. This week has been hell for our entire community. I know we'll come out of this stronger, but that doesn't make this any easier

USDN had a peak mcap over $1 bn. A year ago Alameda deposited over $80 m into their lending protocol vires finance to farm the funding on waves.
Afaik those funds are still locked there and this has been one of the biggest rugs ever. Yet no one was held responsible.

The first one returns up to 10000 recent tx's, while the second one gives up to 10000 recent ERC 20 transfers. What is the difference?
1

From this you get all the data you need, you just have to understand what data did you receive and you can store it
You can write a function that checks for each DEX differently and then you just process a tx and get all DEX trades
One tx can contain multiple diff DEX trades

Example:
Your address: A
Address B sends a tx to a smart contract C that transfers A some ERC 20 tokens
Sender is B, recipient is C
This tx will not show in normal txs of A, but will show up in ERC 20 token transfers

Everyone knows about 3PEEsRmcWspCxhKqobvKY3axW1846AMRwzr
and the $404 583 423.74 debt it has on
@viresfinance
.
But I saw no one talking about the wallet 3PPuzqQC4bHxWitTyndySGcaMzHHNGipQns which is tied to the 3PEE wallet. That wallet has another $ 80 771 047.67 debt (USDC/USDT)

To use infura in python you can use:
from web3 import Web3
w3 = Web3(Web3.HTTPProvider(projectID))
receipt=w3.eth.get_transaction_receipt(trHash)

I like how he posted a thread to clarify, while literally contradicting his first thread.
Some important clarification on my recent tweet thread:
We were not pairing people up to chat with GPT-3, without their knowledge. (in retrospect, I could have worded my first tweet to better reflect this).

Today I found $10 on the sidewalk. Took me about 5 sec to spot it and pick it up.
Just a casual $63M annualized.
This industry is fucking weird man.
So staking my own wrapped friendshare memebership token has earned me about $237~ since yesterday in rewards and trade fees.
Just a casual $86k annualized.
This industry is fucking weird man.

'normal' transactions will give you all the transactions that chosen address either sent or received.
ERC 20 transfers will show all ERC 20 token transfers in/out. Every ERC20 transferred as a part of a normal tx will be here.

Next we check for DEX activity:
Etherscan shows DEX swaps in browser, but you cannot get them from their API
What you need for that are tx's logs
For that you can use
@infura_io
You can go to infura and get their free tier with up to 100 k requests/day
