Building smart contracts in public.

Currently focused on:
– writing & testing Solidity (Foundry)
– on-chain behavior & edge cases
– learning security by breaking assumptions

Posting what works, what breaks, and why.

Build Your First Hook on v4 https://t.co/ALpNoIEB7Z

[Lovro | Smart Contracts & Web3 @J0BSdev]

Looking into Uniswap v4 hooks today.
A lot of new possibilities compared to v2/v3.

[Lovro | Smart Contracts & Web3 @J0BSdev]

Let’s go 🔥
Excited for the next 9 weeks.

[Atrium Academy @AtriumAcademy]

138 developers from around the world just made the cut for UHI9.

Over the next 9 weeks, they'll build @UniswapFND v4 hooks around Impermanent Loss & Yield.

The quest: turn DeFi's oldest problems into opportunity.

Proud to have you. Welcome, UHI9 🎉

Studied Uniswap V2 swaps today.

Simple on the surface, a lot going on underneath.

[Lovro | Smart Contracts & Web3 @J0BSdev]

Advanced Foundry done ✅

Took some time, wasn’t easy, but it all came together in the end.

Moving on to Uniswap.

Got accepted into @AtriumAcademy Uniswap v4 Hook Incubator.

I’ll be working on an execution risk layer for swaps —
classifying toxic conditions before execution and adjusting fees accordingly.

Curious how far we can push Uniswap v4 hooks.

Finished CCIP and finally understand cross-chain messaging + value transfer.

[Lovro | Smart Contracts & Web3 @J0BSdev]

Cross-chain bridging + CCT + CCIP ✅
Learning how chains actually connect.

[Lovro | Smart Contracts & Web3 @J0BSdev]

Finished the DeFi & Stablecoin course on Cyfrin.
Learned a lot — from fundamentals to building the full engine.

DSC engine testing today:
✅ handler tests
✅ mint / redeem flows
✅ collateral deposits
✅ health factor safety

Making sure the protocol behaves correctly under different user actions.

[Lovro | Smart Contracts & Web3 @J0BSdev]

DSC engine testing today:
✅ invariant tests
✅ protocol safety checks

Making sure the system holds under all conditions.

[Lovro | Smart Contracts & Web3 @J0BSdev]

DSC engine progress:
✅ more unit tests
✅ more edge cases
✅ tighter assertions

Tests first. Always. https://t.co/YuAUxuCHFt

[Lovro | Smart Contracts & Web3 @J0BSdev]

DSC engine testing day.
✅ redeem collateral logic
✅ edge cases
✅ revert scenarios

~80% test coverage so far.
Still pushing for more. https://t.co/ZborH0ddIN

[Lovro | Smart Contracts & Web3 @J0BSdev]

DSC engine review today:
✅ health factor math
✅ collateral ratios
✅ edge cases https://t.co/jycPnYATuh

[Lovro | Smart Contracts & Web3 @J0BSdev]

DSC engine progress today:
✅ redeem collateral logic
✅ edge case handling
✅ unit + fuzz tests
✅ invariant checks

[Lovro | Smart Contracts & Web3 @J0BSdev]

DSC engine progress today:
✅ collateral math
✅ mint limits
✅ health factor logic
✅ safety thresholds

[Lovro | Smart Contracts & Web3 @J0BSdev]

Working on a DSC engine.
Learned so far:
✅ mint logic
✅ collateral deposits
✅ price feed integration
✅ health factor calculation https://t.co/THZkDyvzfN

[Lovro | Smart Contracts & Web3 @J0BSdev]

Started working on a DeFi stablecoin + its DSC engine.
Collateral, minting, liquidation — step by step.

[Lovro | Smart Contracts & Web3 @J0BSdev]

Spent some time on abi.encode vs abi.encodePacked today 🧠⚙️
Encode is safer for hashing and signatures 🔐
Packed is smaller, but easier to mess up ⚠️

Details like this really matter in Solidity 💯

[Lovro | Smart Contracts & Web3 @J0BSdev]

@benjamincowen Painful, but makes sense
