​Adevărul este că BlackRock nu dă punct fără nod. Dacă s-a apropiat de Uniswap cu fondul BUIDL, este pentru că "haosul" a fost organizat și infrastructura a devenit standard Faria Lima cu Wall Street.
​A Faxina na Casa (v4 + Hooks): O segredo da "limpeza" tem nome: Uniswap v4. Antes, lucrul era oarecum rigid, dar v4 a adus Hooks ("cârlige"). Imaginează-ți că Hook este securitatea de elită la ușa clubului: verifică cine este cine înainte de a lăsa să intre în pool. Cu asta, #BlackRock⁩ poate crea pool-uri unde doar portofelele cu KYC (identitate verificată) pot intra. Este DeFi cu "miros de bancă", exact ceea ce vrea regulatorul pentru a nu da zebra.

In 2022, I deposited $ETH into a decentralized exchange called FolkDelta, one of the earliest Ethereum-based DEXs.
Everything looked normal — except for one mistake.
I set the gas fee too low.
The result?
The transaction stayed pending for years.
During that long pending period, FolkDelta shut down completely.
To most people, this is where the story ends.
"The exchange is gone.Funds are gone.”
But DeFi doesn’t work like that.
A Year Later, Curiosity Kicked In
After a year, curiosity made me check the transaction again.
This time, instead of panic, I did on-chain analysis.
What I discovered surprised me:
✅ The transaction was now successful

✅ The ETH had left my wallet

✅ The funds were sitting inside the EtherDelta 2 smart contract
The website was gone.

The UI was gone.

But the smart contract was still alive.
What Most People Get Wrong About DeFi
Many people believe:
“If an exchange shuts down, the funds are gone.”
That’s not always true in DeFi.
Websites can die,
Companies can disappear,
Frontends can shut down,
But smart contracts live on-chain — permanently.

Serious Question
Where does your ETH go when a DEX shuts down?
It doesn’t vanish.
It stays inside the smart contract, waiting for the same wallet that sent it to retrieve it.
If you still control your private key, your funds may still be recoverable — even years later.
The blockchain doesn’t care about time.
It only cares about keys.

How the Recovery Was Possible
The ETH was locked inside the EtherDelta 2 smart contract.
To recover it, I used a wallet that supports private key imports and manual contract interaction — MyEtherWallet (MEW).
Steps in simple terms:
Imported the original wallet using the private keyManually interacted with the EtherDelta smart contractCalled the withdraw functionThe smart contract sent the ETH back to the same wallet that originally deposited it
✅ Recovery successful.
No customer support.
No admin approval.
Just math and code.

Final Thoughts
Early DeFi was the Wild West.
Many people didn’t lose funds to hacks —
They lost them to lack of knowledge.

If this story helps even one person understand:
how DeFi really workswhy private keys matterand why “dead” doesn’t always mean “lost”
Then it’s worth sharing.👍🏽

Not your keys, not your coins — but also:
If you have your keys, time doesn’t matter.

Aici este un rezumat al punctelor cheie:

1. Piața & mentalitatea constructorului
- CZ spune că volatilitatea prețurilor zilnice este „zgomot”, constructorii nu ar trebui să se lase influențați; ceea ce este important este să continue să livreze produse și să actualizeze comunitatea indiferent dacă piața este în creștere sau în scădere.

2. Motivația personală a lui CZ
- El subliniază că nu mai lucrează pentru bani, ci pentru sentimentul de a contribui, dorind „să lase lumea un pic mai bun decât atunci când a intrat”, așa că, deși situația financiară este confortabilă, continuă să muncească.
