Feels like natural language interfaces will gradually replace web3 front-ends
Much like how ChatGPT replaced Google Search for finding answers
There are certainly use cases for both, but natural language is 10x more intuitive

Spent the weekend exploring the new @CoinbaseDev AgentKit 0.1.0 release - it is extremely powerful!
I put together an open-source template that allows you to create a web-based, multi-chain agent capable of taking 20+ actions.

Had a great time building learnwhy.xyz at the @theresidency #tastyhacks hackathon this weekend.
In my 8 years as a math tutor, I heard "Why do I have to learn this??" hundreds of times.
LearnWhy customizes lesson plans to each student's unique interests—try it out!

We won $5k at the Coinbase Hackathon and are investing it back into the Toolkit repo via @merit_systems - all contributors who merge PRs get paid!
Join @shafu0x, @alvaroecuesta, @zdql__, and me in building a self-funding open-source repo
🥇 $5,000 – @jsonhedman
Toolkit.dev is an agentic chatbot that generates revenue by monetizing LLM usage and tool calls via x402.
It integrates CDP embedded and server wallets, as well as Onramp and all revenue is sent programmatically from the server wallet to contributors via a merit system.

Thank you all for the incredible support for Toolkit!
During development, my main priority was creating a seamless developer experience for the OSS community to create new integrations.

On-chain casino games have massive potential. With @Aptos's randomness API, that potential is now a reality.
I explored the API and developed the first fully-on-chain decentralized casino: luckyleopards.club 🎲. Keep reading to delve into its architecture 🧵

Fully-integrated @CoinbaseDev stack is beautiful
@x402scan Composer is also powered by CDP Server Wallets!
The x402 eco has an incredible dashboard built by @merit_systems called @x402scan!
This tool leverages @CoinbaseDev's
▫️Data API
▫️Embedded Wallets
▫️Onramp
I used Composer to show how you can leverage @firecrawl's endpoint to scrape the internet for news, and then how you could use that information to create a custom video or image, even as a multi-tool operation with an Agent.

Great tech. Every x402 agent builder should use
CDP Server wallets are honestly incredible tech.
Consistently being able to land hundreds of txs per block means you don't need to sweat going viral.
Policy engine + built in KYT checks keep you safe.
Scale + safety = best in class wallets for AI

1) house.move
At the heart of every casino lies the 'house', acting as the counterparty to all bets.
In LLC, the 'house' takes the form of an Aptos resource account, managed by code rather than any particular user.

My last thread unveiled the fully on-chain casino architecture I developed for the @Aptos RaNd0M Hack.

We currently index transfer events from transactions submitted by known facilitators, which paints a helpful, but incomplete picture
Working to get some docs out asap that will describe it in full

2) game.move
Games interact with the house indirectly through the game.move module. This framework offers a straightforward interface for managing payout functionality.
By restricting house access to functions defined in the game module, potential attacks are prevented.

3,680
1.2) Approved Games
For a game to access house funds, it needs approval from the admin.
When a game is approved, a resource is added to the house account, signifying its approval and defining the vig (fee percentage).

Designed for modularity and extensibility, the casino's architecture allows our team and external developers to create a wide range of games.
The core framework consists of three utility modules that are used by specific games to provide diverse gaming experiences.

1.1) House Shares
The house's backing works like a liquidity pool in an AMM DEX: stake APT to mint HOUSE, which can be burned for a share of the house's assets.
The HOUSE/APT exchange rate fluctuates based on bet results. With a vig on each bet, HOUSE appreciates over time.

🎲 The die is cast in the Aptos RaNd0M Hack, and now it's your turn to decide which innovative projects will come up aces.
🗳️ Community voting is now open on Discord, where the thrill of randomness meets the wisdom of the crowd: discord.com/invite/aptosnetw…
With your votes, we'll determine which project harnesses the power of on-chain randomness most creatively and effectively.
Voting closes on April 5 at 11:59 PM PDT.

The remaining game logic - calculating hand values and determining the payout multiplier based on the player and dealer hands - can be found in the open-source blackjack module.

2.1) Roulette Example
The roulette module provides a sample usage of the game framework.
The specialized roulette.move module governs the core logic of the game (spinning the wheel), while the general game.move module handles verification and payouts.

Far easier to sybil on buy side than sell side
We track ‘sellers’ as unique addresses that receive x402 txns which would require server to constantly rotate the recipient address
Long term there are certainly better metrics
Probably a need for an x402 event on chain too

3) state_based_game.move
To address this issue, the platform offers a state_based_game.move module that utilizes the Aptos Object library for storage, modification, and retrieval of game states.
Internally, this module utilizes the game.move module to handle payouts.
