@shawnsporter @AppLayerLabs C++ Precompile smart contracts are as close as possible to Solidity while using C++! We designed them for easy adoption by Solidity devs, simple yet powerful. Plus, they’r EVM ABI-compatible, so existing frontend tooling works seamlessly. Docs & ERC20 example included!

[Itamar Carvalho | AppLayer 2025 @ItaCraft]

Our game (public very soon) server is a smart contract, can your chain handle that? I bet it can't.

[Itamar Carvalho | AppLayer 2025 @ItaCraft]

Imagine a living, breathing sandbox where every move is on-chain, no servers, just unstoppable decentralized gameplay.

Coming soon… @AppLayerLabs

One key feature of AppLayer is that EVM contracts can leverage C++ precompiles, and vice versa.

For example, a DEX smart contract can be written in C++ to handle ordered arrays, which is impossibly costly in Solidity, while being able to access EVM ERC20 tokens.

[Itamar Carvalho | AppLayer 2025 @ItaCraft]

By using @AppLayerLabs special precompiles (available from Solidity contracts), you can derive safe randomness for your contracts! This offers a superior experience compared to other VRFs, as you don't have to wait for it to be filled! It is a simple as calling another contract.

Designing novel BFT consensus is a blast, until you realize that there are so many edge cases that it feels like you are on a roller coaster to insanity. 🤪 It’s all fun and giggles until your code decides to play hide and seek with bugs!

[Itamar Carvalho | AppLayer 2025 @ItaCraft]

Ends up it was a libstdc++ version mismatch, plus, it only happened inside the IDE that wasn't detecting the correct path for GCC 14. 🤦‍♂️

[Itamar Carvalho | AppLayer 2025 @ItaCraft]

I'm going insane. We want to update to GCC 14 to take advantage of BitInt but now a segfault is happening under very specific conditions in one of our dependencies.

Spent time debugging this only to reach the strangest conclusion: A compiler bug?!?! Maybe, further debug needed.

[Itamar Carvalho | AppLayer 2025 @ItaCraft]

Hey dev, do you want to loop an ordered array in order to make a decentralized orderbook exchange? While in Solidity its prohibitively expensive to do such thing, you can easily achieve this functionality in @AppLayerLabs

[Itamar Carvalho | AppLayer 2025 @ItaCraft]

At ETH Denver, we at @AppLayerLabs benchmarked ERC721 minting in our EVM and C++ implementations. After further development, we've achieved nearly 10x C++ speed and 2x EVM performance for full state transitions. 0.35/s, 2M mints/s theoretically? Lets see what irl data can show 🪨

[Itamar Carvalho | AppLayer 2025 @ItaCraft]

I've updated the benchmark to the current code (underwent multiple refactors for improved performance since last year).

Now, in @AppLayerLabs BDK, a UniswapV2 swap can be completed in a single microsecond instead of 3.5, an over 3x speed improvement...
