Will 1-click swap-sends be a future feature of DEXs?
Will 1-click swap-sends be a future feature of DEXs? 👇
When you send a token to someone, the amount you enter is what the payer receives (you pay gas on top).
When you use a DEX, the amount you enter is not what you receive - this amount includes fees/slippage.
If you want to pay someone in a token you don't have, the current process would be to perform the swap first then send the tokens after.
It would be more convenient if you were able to swap-send, especially if you don't want tiny bits of the swapped token lying around.
How do you interact directly with an Ethereum smart contract?
"How do you interact directly with an Ethereum smart contract?"
Step-by-step example below 👇
⚠️Ability to read code is required⚠️
#JeremyAnswers #solidity #blockend
There are a few ways to do this but I'll go over the one which doesn't require any setup.
Note: This method only works if the contract you want to interact with has verified it's source code on Etherscan.
What is tâtonnement and how does it relate to Ethereum gas prices?
"What is tâtonnement and how does it relate to Ethereum gas prices?"
#JeremyAnswers #web3 #web3dev
"Tâtonnement" is an economics term which describes an iterative auction process that aims to maintain a state of equilibrium with respect to trades.
The word is borrowed from French where it can mean "groping" or "trial and error".
How does the Ethereum Virtual Machine (EVM) store smart contract data?
"How does the Ethereum Virtual Machine (EVM) store smart contract data?"
#JeremyAnswers
Each smart contract has it's own permanent storage. The storage is a one impossibly large array.
The array is 2^256 elements in length and each element is 32 bytes wide.
You may have already guessed, but this array is completely virtual.
What is the difference between collateralized stable coins USDT, USDC and DAI?
"What is the difference between collateralized stable coins USDT, USDC and DAI?"
#JeremyAnswers
USDT is issued by Tether, a HK based company. It has the highest market cap and the most trading pairs out of the 3.
In the past, USDT was involved in some controversy regarding the transparency of it's reserves. This no longer appears to be an issue:

What is arbitrage trading in crypto?
"What is arbitrage trading in crypto?"
The following thread is not financial advice.
#JeremyAnswers
It's a relatively low-risk trade where you buy a token in one place and immediately sell it somewhere else for a small profit.
The profit you make from this kind of trade comes from the price discrepancy between the place you bought the token and where you sold it.
What is the difference between an algorithmic stable coin and a collateralized one?
"What is the difference between an algorithmic stable coin and a collateralized one?"
#JeremyAnswers
Background:
A stable coin is a type of cryptocurrency which attempts to keep it's value equal to the value of another asset, this is known as "pegging".
Stable coins are most commonly pegged to fiat currency, e.g. UST, USDT, DAI, BUSD, AUDT etc.
What is slippage?
"What is slippage?"
#JeremyAnswers
When making a trade, slippage is the expected difference between the quote and execution price. It is expressed as a percentage.
Example:
Quoted price - $10
Slippage - 10%
Maximum expected price - $10 * 1.1 = $11
The Future of Privacy and Identity
The Future of Privacy and Identity:
I think it's important to be able to decouple the various faces of your real life identity. I assume most of us do it on a near daily basis (e.g. How you behave around friends vs your boss).
If you weren't able to keep certain parts of your life private, it could end up being detrimental for your overall health.
E.g. An addict not being able to get help anonymously or disclose certain details to their doctor in fear they might get fired/arrested.
Parasitic Protocol Ponderings
Protocols built to farm other protocols. Parasitic leeches? or is a symbiotic relationship possible?
This behaviour isn't limited to protocols, I think a system or collective whose sole purpose is to farm another system counts too.
Examples?
- REDACTED -> Convex -> Curve
- P2E game academies/universities
- Mining pools to a certain extent
