Btw, if you're a web3 startup and are looking for a mid-level backend dev - DM me!!
I bring great workEx and even better side projects (yes there's web3 & even solidity!), along with the obviously good sense of humour 😎

I'll be trying out different approaches for the smart contract next:
Option A: One Swabby managing it all - an order book for everyone's savings
Option B: One Swabby for every wallet - one swabby instance created for one wallet
Low gas fees will be my top priority!

👀 Made a demo for the Swabby, an on-chain smart HODLing protocol.
Get that good night's sleep without worrying about your altcoins falling to zero, Swabby will swap them out before they do. (Psst.. you won't have to sign the tx 🫡)
Got any feedback?

Woah! This was really absurd. They didn't care about YGG being a competitor when it was handing out money but now they do? I'm sure they must've had their reasons to want them out now but pushing out an investor like that doesn't seem right

Uhh… a massive DAO just voted to “refund” one of their investors who was owed a 30x return ($5M+)
This is an insane story that impacts all builders in web3 and as a founder I need to speak out
Merit Circle DAO vs YGG

You ask them for another withdrawal and they end up forgetting about updating your balance from the previous withdrawal.

You ask them to withdraw 1000$ from your account. You did have the money in your account so they deduct it and hand it over to you. BUT, before they can update the balance in the spreadsheet, you interrupt them.

Imagine this scenario:
You go to your bank🏦for a withdrawal and your bank teller has a poor short term memory. They store all account balances on a spreadsheet to avoid losses for the bank and to save their job

Went deep down into the rabbit hole - can now understand how to decode input data - after hours of trying, the sense of achievement is so satisfying!! 🥳🥳
If anyone else wants to understand what a transaction's input data means: trustology.io/insights-event

@etherscan How does the website make sense of the input data of a transaction?
e.g. etherscan.io/tx/0xd5fd1f841 how does it figure out the 9 token transfers that took place as part of this parent transaction?

And if the condition that you're evaluating is too complex to fit into the require statement - use the revert statement instead.
Checkout this example: solidity-by-example.org/error

Web3 - Solidity tip
Like require you also can use assert. The difference:
- require will refund you the rest of your gas if it failed.
- assert won't refund you any gas
When to use what?
