GTA 5 ON CHAIN

Demo

About

Our project brings GTA V fully on-chain by linking in-game actions to blockchain transactions. Using Pyth’s on-chain entropy, we generate provably random outcomes that shape missions, events, and interactions triggered directly from the in-game phone. Every player is identified by their ENS name, which we also use for seamless transfers and in-game operations. Wallet management and peer-to-peer payments are powered by CDP, giving players smooth on-chain control without leaving the game. For commerce inside the world, x402 powers our in-game stores, letting players buy, sell, and interact with on-chain assets natively within the GTA experience. Our in game currency was minted on a Base launch pad. https://flaunch.gg/base/coin/0xa901a7b9897c8d49847834514969a8bcbc1f9b92

How it's made

💥 How It’s Made — GTA On-Chain Edition 1️⃣ GTA V Mod (ScriptHookV / FiveM) 🎮📱 We build a custom GTA V mod that hooks directly into the game’s scripting layer. It listens for in-game events — especially anything triggered from the in-game phone — and forwards them to our backend bridge. Hooked events include: 📱 Phone menu selections 👤 Player interactions 🎯 Mission triggers 🛒 Store purchases 🖥️ Custom UI actions The mod communicates with a local bridge server (Node.js) over HTTP or WebSockets. 2️⃣ Local Bridge Server → On-Chain 🔗💻 This local Node.js bridge translates GTA events into blockchain transactions. The bridge handles: 📥 Receiving events from the GTA mod ✍️ Signing + sending smart contract transactions 📖 Reading contract state and returning results 🔑 Managing wallet sessions via CDP This allows players to perform on-chain actions using only the in-game phone. 3️⃣ CDP (Wallet Management + P2P Transfers) 🔐💸 We use Coinbase Developer Platform (CDP) as the wallet layer. CDP powers: 🗝️ Non-custodial wallets for each player 🔑 Session keys (no seed phrase popups) 🤝 Instant P2P transfers 🎮 Fully in-game UX (no browser needed) CDP makes blockchain interaction feel like a native GTA mechanic. 4️⃣ ENS Integration 🌐🆔 Players log in with their ENS names. ENS is used for: 🪪 Player identity 🔤 Display names 💸 In-game payments (send to felipe.eth instead of 0x...) 🧾 Store receipts 🎁 Mission rewards The bridge resolves ENS → address before sending any transaction. 5️⃣ Pyth Entropy for Randomness 🎲⚡ We use Pyth on-chain entropy to generate provably random events. This randomness powers: 🎯 Mission outcomes 💰 Loot drops 🧨 Risk-based decisions 🐉 Spawns, dice, random events Because it’s on-chain, it’s: 🔍 Verifiable 🎭 Unpredictable 🛡️ Tamper-resistant It makes missions feel truly blockchain-native. 6️⃣ Smart Contracts (Core Logic) 🧩📜 Smart contracts handle gameplay logic that needs: 🎲 Randomness 📊 State tracking 💸 Payments 🎒 Item ownership 🗺️ Mission progress 🛒 Store purchases Deployed on a chain with: ⚡ Fast confirmations 🪙 Cheap gas 🎰 Reliable entropy All triggered directly from the GTA phone UI. 7️⃣ x402 for In-Game Stores 🛍️🔗 x402 powers the marketplace/store layer: 🛒 Buy/sell digital goods 🪙 On-chain item minting 💵 Pricing + inventory 📦 Auto-delivery to GTA inventory We map x402 items → GTA items inside the mod. 8️⃣ Game → Blockchain → Game Loop 🔁🚀 Here’s a typical flow: 📱 Player opens in-game phone ➡️ Selects action (store, mission, transfer) 🎮 Mod sends event → Bridge 🔗 Bridge signs & sends TX 📜 Contract executes (randomness, payments, state updates) 🧠 Bridge reads results 🌍 Mod updates GTA world (loot, mission outcome, purchases) Everything feels instant, even though it’s fully on-chain.
