1/ ERC-20 token standard approve() has caused an unnecessary cost of $53.8M for #Ethereum and #DeFi users

This is bad. Continue reading why and how to avoid this in the future.

👇👇👇

 2/ Before you go all rage on the flaws of my analysis, please read the whole Twitter thread for disclaimers and caveats.
3/ approve() is an unnecessary step of ERC-20 tokens when they interact with smart contracts.

You know this because when you do a Uniswap trade you need press two transaction buttons instead of one.
4/ Why there is approve() - you can read the history in this Twitter thread

https://t.co/ZHXzPBbqJJ
5/ I queried all approve() transactions on Google BigQuery public dataset and calculated their ETH cost and then converted this to the USD with the current ETH price.
6/ These queries were made possible to awesome @EthereumETL team. They have created Google BigQuery dataset from real-time blockchain data. You can query over terabytes of Ethereum data FOR FREE.
7/ Here are instructions on how to execute your own queries:

(But links are outdated because Google Cloud has new UI)
8/ Total transaction on #Ethereum blockchain: 989,461,092

Woo! One billion transactions will be done in a few days!
9/ Total ERC-20 transfers(): 304,382,558

Includes only Externally Owned Accounts, EOAs.
10/ Total ERC-20 approves(): 14,921,106

Includes only Externally Owned Accounts, EOAs.
11/ The gas cost ERC-20 approves():

41327.870139658684 ETH
12/ Here is my query

https://t.co/FqNWBAxjwt
13/ You can query Ethereum transactions that call a particular smart contract function by the 4-byte signature of the function that is 1st parameter of tx data field.
14/ Binary function signatures are 4-bytes keccak256() hash of the @solidity_lang signature string. Here is an example:
15/ If you are a @solidity_lang or Vyper developer, consider ditching ERC-20 and include alternative token standard in your next token.

Alternatives for ERC-20 include:

ERC-777
ERC-667
ERC-827
ERC-223
(did I miss any?)
16/ Most of the new token standards, like ERC-777 are backwards compatible and work with ERC-20 enabled centralised exchanges.

Centralised exchanges do not need to do anything to support these new, better, token standards that make smart contract and #DeFi interactions safer.
17/ Or let's put it this way...

Every time someone creates a new ERC-20 token, hundreds of thousands of dollars die.

Let's actively demanding non-ERC 20 tokens from developers.

And if that does not work I suggest we start punching ERC-20 developers to face over the internet
18/ Newer token standards may "increase the attack surface", but in practice, this has not been a problem for high-quality #DeFi projects since 2018 or so.
18/ Note that raw approve() cost calculation comparison to newer token standard is not 1:1.

Newer token standards need some similar mechanism to pass user data as the part of the transaction, but this cost is lower compared to additional approve() tx.

Prove me wrong.

Will start this thread with a disclaimer. I have never invested a rupee in cryptos 😀

But I have studied bull and bear cycles and financial bubbles extensively. Saw 1992, 2000, 2008 with own eyes. The first one as a novice, the next two when I knew to analyze

The amount of chatter I am seeing in friends, family and social media about cryptos has gone through the roof. For everyone, it's a dream to make 100x or even 1000x easily. Basically, become stinking rich easily
( it never happens )

In any financial bubble, the top is made in extreme speed and violence. The distribution happens on the way down. Unless one saw the rates of 65k on bitcoin, one wouldn't buy at 30-35k or 20k. That 65k is an anchor point which leads to greed

During the tulipmania, a single piece of tulip reached a price of $750,000 in today's money. When we see that history, we think "what idiots". But consider this, as of now meme coins generated by someone in their garage are being traded at absurd prices


Then there is this joke called NFT. A piece of "digital art" basically made by someone on their computer ( who is not even a known artist) are being sold for millions of dollars

We are actively working to launch on @binance Smart Chain #BSC .

To make this transition easy & understandable for everyone, we are answering most frequently asked questions here.

Ready? Go! 🔥

#DeFi #YieldFarming


Q1 - What are the benefits of holding the $VALUE token on the Ethereum Mainnet network? Give me reasons not to sell. Some are assuming that the VALUE token will be abandoned now that vBSWAP is being created. Can you clarify the use case for VALUE?

👉 $VALUE will always be a governance & profit receiving token of the whole ecosystem if staked in #vGov. With the new farming token on #BSC , gvVALUE holders will get extra rewards at BSC if they choose to bridge their gvVALUE to BSC & stake in gvVALUE-B/BUSD 98/2 pool.

Q2 - What do I need to do with my VALUE tokens that are staked in vGov? Is it OK to leave them in the vGov?

👉If you have VALUE but aren't staking in the vGov & you would like to participate in the BSC expansion, you will need to stake your VALUE in the vGov to receive gvVALUE.

If you are staking in vGov but don't see the correct gvVALUE amount in your wallet, go to vGov (https://t.co/udXn5IJtVx) to unlock your gvVALUE from the old contract. There will be a bridge from ETH to BSC to move gvVALUE and vUSD over.

Prepare For The Biggest Bull Run In Crypto EVER.

I made some charts explaining the long term trend of #Ethereum and how identical it is to the early #Bitcoin cycles.

It's very obvious what's happening and has been in the charts for months.

I call this pattern the, "4 Year Bowl."

New years are a time of market shifts both bullish and bearish. Each cycle goes through 4 years of this rounded accumulation pattern. After year 4 we start 1 year of parabolic rise.


When you take a look at the same principle with the last #Bitcoin cycle you get almost the exact same outcome. Only difference is Bitcoin usually tops at the first of December and not January.

The 4 Year Bowl is identical with Ethereum and Bitcoin


When you lay them side by side you get a pretty insane correlation. The fact $ETH accumulated for 2 years at that range low makes me feel as if the parabolic rise will happen faster than everyone thought.

Look how identical it is to the last $BTC cycle. Who could argue against?


S/O to @BobLoukas for teaching me how cycles work. I was one of the first members on @BitcoinLive1 and Bob was the only person I listened to. True Legend.

So... How does "4 Year Cycle Theory" work?

Measure from peak low to peak low. Each cycle equals 4 years in distance.

The CBN's official reason for its recent cryptocurrency restriction is that cryptocurrencies are anonymous and used for money laundering, terrorism financing, and tax evasion. Let’s dig into what the facts say.

A THREAD #Nigeria #Bitcoin

1/21

We’ll break up the allegation into two. First up, “cryptocurrency is used for money laundering.”
Cryptocurrencies have been used for illicit activities but so too have official currencies. So the CBN's argument must be that cryptocurrencies make the situation worse.

2/21

But as things stand, significantly more illicit activities are conducted with regular money than with cryptocurrencies. According to the UN, between $800 billion and $2 trillion is laundered globally every year, mostly in cash.

3/21

Meanwhile, the entire global value of cryptocurrencies is currently $1.4 trillion. Chainanalysis, the leading crypto-analysis company helping governments track criminals, estimated that 1.1% of all cryptocurrency transactions are illicit.

4/21

So, if the government is trying to clamp down on money laundering and terrorism financing, they are better off spending their energy on their naira accounts.

The new age of privacy, and the crypto ecosystem that will enable it.

A Thread.
$XHV $SCRT $RUNE
1/

Throughout my research, @HavenXHV The Haven protocol renewed my faith, that privacy wasn't just a temporary trend, but something with actual, sustainability. The creation of a private bank, exchange, and access to real world assets in completely privacy of my own vault. $XHV
2/

Haven's offering to the world, with it's private assets $xUSD $xEUR $xGOLD and xSilver, made me research what else can be done privately, now that I have private stable coin options. My first question was, if I wanted to sell my private assets, how would I do it? $XHV
3/

It didn't take me long before I discovered $RUNE and @thorchain_org and their cross chain liquidity pools and decentralized exchange capabilities. How anyone can offer liquidity and earn rewards and trading fees for doing so. But also,how all trading pairs,are interchangable.
4/

This made me realize that as Thorchain grows in popularity,they will provide the ability for everyone, across the cryptosphere,to trade any coin for any coin. Kind of like uniswap, but cross chain,and outside, yet including, the erc-20 ecosystem. It's uniswap on steroids. $XHV

Ok, here is a thread for you.
What happens when you have:
Netflix
Apple
Amazon
WarnerMedia +
Disney+
SonyCrackle (Reboot)
Verizon All Access (after they buy CBS/Viacom)
UniversalSkyMedia
By 2021
Answer? Internet Slows To A Craw and Dies.
Why?
Bandwidth.

Netflix's gets 35% of all internet traffic.
Now we all know Apple Coming to Netflix Corner.
We know that WarnerMedia Planning One
We Know about Disney+
Now how will the net handle 8 Streaming Platforms all at once?
Answer - IT CANT.

But Novid, the speed, the 4K the all everything?
NOOOOO BUDDY.
Even if you could do it and even if AWS ran six million clouds, The Net Will still slow to a crawl. 35%, goes to nearly 90% if any of the 8 or all of the 8 eat at netflix's numbers.

Oh, they wouldn't be running at once.
FOOL. You forget how bad things were when game of thrones season premieres came around. HBO SERVERS FALL DOWN GO BOOM!

Now see if a season like 2021 come around and they air shows on a same day. It gets crazy. AT&T and others gonna realize they cant build out forever. Something will give and it might be your entertainment consumption big time.

I have to make a note before writing about this episode. I was the person (still am) who thinks that bringing back D. was a bad idea. I repeat it that for me the writing of S1 and S2 is like tossed into the bin with that plot evolution, but they had to invent something+

+ to be able to continue to prolong the general story after Aslan’s story did not work out. All the suffering of M., all the crying seems for “nothing” for two seasons and we viewers are also kind of fed up in seeing him cry all the time when with the upcoming episodes+

+he is justified the most to cry. With her resurrection now the attention shifts back to Miran’s storyline and I don’t know if I like this to be honest. This said, Dilsha is here and we have to deal with her.

So, my comments are going to be how I find they wrote her into the story, the details we get to know, the flashbacks we get to see, the way it was filmed and directed, with leaving out if I agree on it or not but describing along the way what I saw.

The Straddle is my favorite trade these days. But more often than not, one needs to adjust to make a good return from it. There are many ways to do this depending on your view, psychology and imagination. Will discuss a few that I use

The Straddle is a delta neutral strategy and it is important to keep deltas in check during the course of the Trade and not let them run away from you. Of course Volatility is the elephant in the room- but not going there as that will require a separate discussion

The first and most common method is to go 'inverted.' That is to say to shift the untested side to generate additional Premium and increase the runway to Breakeven. So if you start with a Straddle at 700 and price goes to 740, you can move the PE up to say 720.

How much should you move the untested side? While again this is a matter of skill, experience and artistry, the rule of thumb is to cut deltas by half. Remember, prices will move and you have to allow sufficient room for them to fluctuate

The second method is to shift the entire Straddle in the direction of the move. So if you have a 700 Straddle and Price goes to 740, you can shift the Straddle to 720. If you time this right, it can generally be done at virtually no cost or minimal cost.

The first ever world map was sketched thousands of years ago by Indian saint
“Ramanujacharya” who simply translated the following verse from Mahabharat and gave the world its real face

In Mahabharat,it is described how 'Maharishi Ved Vyasa' gave away his divine vision to Sanjay


Dhritarashtra's charioteer so that he could describe him the events of the upcoming war.

But, even before questions of war could begin, Dhritarashtra asked him to describe how the world looks like from space.

This is how he described the face of the world:

सुदर्शनं प्रवक्ष्यामि द्वीपं तु कुरुनन्दन। परिमण्डलो महाराज द्वीपोऽसौ चक्रसंस्थितः॥
यथा हि पुरुषः पश्येदादर्शे मुखमात्मनः। एवं सुदर्शनद्वीपो दृश्यते चन्द्रमण्डले॥ द्विरंशे पिप्पलस्तत्र द्विरंशे च शशो महान्।

—वेद व्यास, भीष्म पर्व, महाभारत


Meaning:-

हे कुरुनन्दन ! सुदर्शन नामक यह द्वीप चक्र की भाँति गोलाकार स्थित है, जैसे पुरुष दर्पण में अपना मुख देखता है, उसी प्रकार यह द्वीप चन्द्रमण्डल में दिखायी देता है। इसके दो अंशो मे पीपल और दो अंशो मे विशाल शश (खरगोश) दिखायी देता है।


Meaning: "Just like a man sees his face in the mirror, so does the Earth appears in the Universe. In the first part you see leaves of the Peepal Tree, and in the next part you see a Rabbit."

Based on this shloka, Saint Ramanujacharya sketched out the map, but the world laughed
