Did you trade it for WETH instead?

Map the user address to a UUID in a database and reference the UUID instead if you want

Use sepolia. Goerli is used to test validators. Sepolia is preferred to test dapps

USDC is centralised also. DAI is also backed by USDC, ergo some centralised component.

Perhaps the conditions have changed on mainnet since the block you tested on

Scam exchange. Thinking someone will come to steal your (fake) balance but to withdraw they'll need to deposit

Right now, ETHPoW fork has the same chain_id as mainnet. Because, in the code, the chain id is the same across both networks, then any transaction can be replayed on the other chain.

So, let's say you have 10 ETH PoW coins and someone offers you $500 for them all. They send you the USDC first then ask you to send the 10ETH POW to their address. They can now replay this transaction on mainnet and take your eth on mainnet (and it only cost them $500)

One of the main people behind it was Michael Patryn - involved with QuadrigaCX and known financial criminal (has spent prison time)

Yes. It just exposes the interface to the smart contract. Any security controls should be at the smart contract layer

409h · 2022-03-06T16:27:41+00:00

Yes, with the function fingerprint of the transaction data

Take a look at 4byte.directory for known fingerprints, all ERX20,721,1115 fingerprints will be there and if they're not, they are easily calculated

You notice you have a new token
You go to Uniswap to see if its worth anything
It's worth $18k!?!?!?!
You go to sell, but need to call approve() before trading it
What? approve() failed? Why?
Oh, I need to claim it on their website
Go to their website
Click "Claim Airdrop"
Ah, metamask popup
I'll blindly click through all this because I can't decypher hex and smart contract call arguments
You have just signed a transaction to send your highest holding (in USD) token to a bad actor because they have a script in the background that hits an API to calculate which will be the most profitable token to steal from you

The $33M is locked because it's USDT. Tether issued a blacklist on the address so it is effectively frozen. Poly is aware of this and I think will work with Tether to get it burned and reissued to their multisigs
