@Haskell_Gz Leyendo un poco tu post crees que hacer delta neutral pueda jugar en contra? Debido a que quiza no termines con un PnL positivo, obviamente tenieneo todos los cuidados que hay que tener de por si con esta estrategia en aster

[manumafe.eth @manumafe_eth]

@Javier61997 @Inpunkcrypto @pacifica_fi Capaz tambien prima la cantidad de tiempo por tener la posicion abierta

[manumafe.eth @manumafe_eth]

@DragonCrip Posiblemente futuros 200k y spot 50k

O hiciste mix de spot y futuros?

Aca dejando my primera review al goat @PastanagaCrypto on @ethos_network

[manumafe.eth @manumafe_eth]

@Haskell_Gz Decis aue premien el uso de la app? Yo por ahora solo estuve utilizando la web para farmear

[manumafe.eth @manumafe_eth]

@Elchurrasquero1 @ethos_network Opa, me interesa, si todavia la seguis teniendo

[manumafe.eth @manumafe_eth]

@lodelascripto @monad @squidrouter @HelixMarkets @jumperapp @base Y en todo caso con la cantidad de uso que tienen ambos tiene pinta de que si ocurriera seria difícil que sea uno bueno jajaja

[manumafe.eth @manumafe_eth]

@ProscritoInvest @BasedOneX @pacifica_fi @Lighter_xyz Yo la verdad ya edtoy tarde para Lighter, asi que estaba con based, pero creo que farmearlo con otro dex y diluir por ej pacifica no se si es lo mejor

Estuviste haciendo estrategias comprando en spot y shorteando para las funding? Esa es una que todavía no implemente

[manumafe.eth @manumafe_eth]

@CiscoCANFT @BasedOneX @smartbitrage Me genera dudas tipo cuanto tiempo tener abiertas las operaciones ponele, usas SL y TP? O estas revisandolas cada cierto tiempo? Entiendo que también solo se pueden usar stables para estas operaciones, cierto? Gracias por la buena onda por cierto

[manumafe.eth @manumafe_eth]

@CiscoCANFT @BasedOneX @smartbitrage tenes algun tip para arrancar (o hilo para algun paso a paso), todavia no arranque a hacer delta neutral en ninguna plataforma y creo que podria ser una buena oportunidad, gracias!

[manumafe.eth @manumafe_eth]

@LexMorenoCripto Lo arrancaste a farmear organicamente? o con delta neutral

[manumafe.eth @manumafe_eth]

@0xusmanf Thanks! I have another doubt where are those nft challenges that you mention?

🔐 Avoid One of the Most Common Smart Contract Vulnerabilities: Reentrancy

When building in Web3, security must come before functionality. A single overlooked line of Solidity can cost millions.

One of the most notorious bugs in Ethereum’s history — the DAO hack — happened due to a reentrancy vulnerability.

Let’s break it down and learn how to avoid it 👇

---

Solidity’s CEI pattern is a best practice that drastically reduces your attack surface:

- ✅ Checks: Ensure valid conditions (e.g. `require` the user has enough balance)
- ✏️ Effects: Update state variables (e.g. subtract balance)
- 🔁 Interactions: Make external calls (e.g. send ETH with `.call`)

Why this order?

Because if an external call (like `https://t.co/atycFu6Ikc`) triggers malicious fallback logic, it can re-enter your function before the state is updated — stealing funds repeatedly. This is reentrancy.

---

🧠 Why Does CEI Work?

Solidity's transaction model means if anything in a function fails, the entire transaction reverts — including any state changes done before the failure.

So when we move the state change before the external call, even if the call fails or is exploited, everything rolls back to a safe state.

🚀 Bringing Real-World Data On-Chain with @chainlink

Smart contracts are powerful, but they have one key limitation:
🧠 They can’t access real-world data on their own. This is known as the Oracle Problem.

So, how do we solve it?

🔗 Enter Chainlink – a decentralized oracle network (Layer 2) that enables smart contracts to securely access off-chain data.

🔍 What are Chainlink Data Feeds?

Chainlink provides Data Feeds – secure, reliable, and decentralized sources of external information (like weather, sports scores, and prices).

💰 A powerful subset: Price Feeds
These offer real-time market data (ETH/USD, BTC/USD, etc.) you can trust.

🛠 Want to see how it's implemented?

✅ Check out my contract using price feeds on Sepolia: https://t.co/UZpvKoaC03
✅ Check the GitHub repo implementation: https://t.co/EFZGN83PS8
