@thekiro0 Smart wallets use Account Abstraction to improve user experience, enabling features like gas abstraction, batching, and flexible authentication. Some designs reduce or replace reliance on traditional seed phrases, making them easier for new DeFi users.

@thekiro0 Now when you advance your knowledge, you'll come to realize other kinds of much improved wallets called smart wallets that are much easier to interact with and handle. Smart wallets use Account Abstraction to make things easier without the need for seed phrases (new DeFi users)

Your crypto isn’t in your wallet. It lives on the BLOCKCHAIN. — Day 10 Your wallet holds 3 things: ADDRESS — where you receive crypto. PRIVATE KEY — proves it’s yours. SEED PHRASE — full access to your wallet. Lose your private key or seed phrase? Gone. Forever.

@timsilva112 Good progress keep pushing my friend, No giving up NO MATTER WHAT🙂(politely of course🙃)

@BarnabyChainDev I didn't do all today Some I did over the the week🙂

Today's #solidity grind:Merkle Airdrop contd ✅signature standards ✅ took a quick quiz ✅Decoding ECDSA #signatures ✅Transaction types intro ✅Blob #Transactions ✅Understanding Type 113 transaction ✅Took another quick quiz ✅Implementing Signatures ✅Another quiz 😪

@actlysis Am already going through the discussion @BarnabyChainDev sent me

@timsilva112 @actlysis Wow great, Is it of help?😃

I've been trying to bridge my #rebasetoken but i always end up with errors for close to a week now🤧 am already being frustrated. currently reading solidity docs as i try to solve the errors can any of you help?

@rosarioborgesi Small fix: call doesn’t “not revert” — it returns a bool. If you check it and revert, same behavior as transfer. transfer auto-reverts but only sends 2300 gas (can break). call is flexible — you just handle the revert yourself.

📌 Transfer vs Call — what actually reverts? When sending ETH: 🔹 transfer ❌ reverts automatically on failure 🔹 call ⚠️ returns false, does NOT revert 💣 Hack Example — King of the Ether If they had used call instead of transfer, the hack wouldn’t work 👇

I also added two modifiers : requireFromEntryPoint -> for function validateUserOp to be called by the entryPoint contract requireFromEntryPointOrOwner -> so that either the owner of the smart contract account can call execute function or the entryPoint contract

@ChidiebereEzen4 Yep but it's not a failure as long as you showed up

@BarnabyChainDev Some days can stretch you thin

🐉 ✅Day 95 Mastering Blockchain Today humbled me…hard 😤 Spent Hours debugging a Foundry issue. Not my code → dependency mismatch. File didn’t exist in that version. 💡Lesson: verify versions. Web3 bugs ≠ always your code. Painful…but I leveled up 🚀 #web3 #cyfrinupdraft

@whitecrow_dev Thanks aton mate🙂

@BarnabyChainDev Great work man! Your dedication is very motivating ngl😅 Keep it up

@JB_Xponential @rosarioborgesi so using transfer is the best practice? and simple....?

@rosarioborgesi True, but saying the hack “wouldn’t work” depends on implementation. call prevents forced reverts, but if unchecked, it opens the door to inconsistent state and logic flaws.

@Olaniyi_dev Keep going👏

Class is in session. A wise man once told me the best way to learn is by doing. My github is looking very good these days. 🤍

@timsilva112 Are you sure you understood all that at once?

What is ERC-777? -An advanced token standard designed to improve ERC20 token. Key Features: -Backward Compatibility -Hooks(send/receive triggers) -Operator system -Better contract interaction Why Not widely used? -Reentrancy risks✳️ -ERC20 -> dominant -Industry supports ERC20

🐢 Day 94 Mastering Blockchain ✅Advanced Foundry -Repeated validateUserOperation function -Imported & reviewed IEntryPoint.sol >=0.7.5 before implementing it on ethAccountAbstraction.sol ✅Chainlink Fundamentals -ERCs & EIPs review(ERC-777) -Libraries & Inheritance review

@thekiro0 This is awesome and super great🫡 Keep the fire burning mate.

1 week of learning crypto from zero. Here’s what I covered 👇 Day 1 — Blockchain Day 2 — Crypto Transaction Day 3 — After you send crypto Day 4 — HASH Day 5 — Why blockchain is hard to hack Day 6 — Miners vs Validators Day 7 — Consensus 7 days. 7 concepts. Day 8 today👀
