SplitBot is an autonomous financial co-pilot that lives directly inside your group chats. It transforms conversational context into trustless financial execution. By leveraging multimodal AI, SplitBot listens to voice notes and text messages to maintain a real-time shared ledger for group trips, high-intensity events, or shared living.
Unlike traditional trackers, SplitBot is a Sovereign Agent (ERC-8004) that manages a decentralized escrow pool. It uses Lit Protocol TEE to ensure that private keys are never held by a single party, enabling the agent to autonomously calculate debts, execute payouts via MiniPay, and programmatically enforce fairness through deposit slashing.
This project doesn't just build a bot; it implements the complete decentralized agent infrastructure required for the next generation of on-chain economy.

The TripEscrow.sol contract manages group funds with integrated agent permissions.

| TripEscrow | Celo Sepolia | 0x79cB34E300D37f3B65852338Ac1f3a0C1ED6Ca29 |
| Agent Identity | Celo Sepolia | Agent ID #222 (ERC-8004) |
The TripEscrow.sol contract serves as the decentralized settlement layer for all group financial interactions. It acts as a non-custodial vault where funds are managed by the SplitBot Agent's verifiable logic.

TripEscrow at the start of the trip. The pool now contains 300 USDC./settle.settleExpense(Alice, 100 USDC).SplitBot is designed to be flexible for different group trust levels. It supports two distinct settlement strategies:
Direct P2P Settlement (Demo Mode):
Trustless Escrow Pooling (Hardcore Mode):

AgentVault is the "Persistent Brain" of the SplitBot. It ensures the Agent has perfect memory across restarts while maintaining absolute privacy.
| Layer | Technology | Purpose |
|---|---|---|
| Privacy | Lit Protocol (TEE) | Encrypts the Agent's state (Transactions/Registry) using Threshold Cryptography. Only the Agent's logic can see the plain text. |
| Storage | Pinata / IPFS | Provides a decentralized, immutable home for the encrypted memory. |
| Economic Barrier | Thirdweb x402 | Implements a tiny micropayment (USDC) for every "Memory Save" to prevent spam and fund the Agent's operations. |
| AI Processing | Gemini 1.5 Flash | Interrogates the recovered memory to provide conversational responses and dynamic balance tracking. |

Spreadsheet Fatigue: People spend more time manually logging costs than enjoying their trips.
Social Trust Friction: Relying on friends to "remember" to pay often leads to awkward reminders and uncollected debts.
Manual Execution: Sending dozens of individual P2P payments at the end of a trip is error-prone and tedious.
Data Fragmentation: Financial history is scattered across apps, bank statements, and chat logs, with no verifiable source of truth.
✅ The Solution
SplitBot turns group conversation into autonomous financial coordination.
Multimodal Logging: The AI understands natural language. Just say, "I paid $80 for the car," and the shared ledger updates instantly.
Trustless On-Chain Escrow: Users deposit USDC into the TripEscrow contract at the start. Funds are managed strictly by the Agent's logic, not the developer.
Agentic Settlement: With one command (/settle), the Agent verifies debts across the group and executes all payouts simultaneously.
Programmable Fairness: If a user defaults or "ghosts," the system can slash their initial deposit to cover the missing liquidity, ensuring no one is left out of pocket.
Persistent Reputation: Powered by AgentVault, every interaction builds a verifiable on-chain reputation for both the user and the agent, moving trust from the social layer to the protocol layer.
