Crypto investing remains fragmented, stressful, and insecure.
Users must continuously monitor markets, evaluate countless information sources, manage gas fees, sign transactions, and manually enforce risk controls. Existing trading bots introduce another problem: users must trust a single automated system with significant authority over their funds.
At the same time, AI agents are becoming increasingly capable. However, allowing a single AI model to directly manage capital creates a dangerous single point of failure.
Sentinel AI solves this problem by introducing an Autonomous Onchain Investment Committee powered by multiple specialized AI agents, MetaMask Smart Accounts, ERC-7715 Advanced Permissions, ERC-7710 Delegation, x402 Payments, and 1Shot Permissionless Relayer infrastructure.
Rather than trusting a single AI, users delegate limited authority to a committee of specialized agents that research, debate, validate, and execute decisions within strict onchain security boundaries.
Most AI investing solutions rely on a single reasoning engine.
Sentinel AI introduces a Multi-Agent Consensus Architecture where every decision is challenged before execution.
Instead of one AI saying:
"Buy ETH now."
Multiple agents participate:
Bull Agent searches for upside opportunities.
Bear Agent identifies risks and bearish signals.
Yield Agent evaluates DeFi yield strategies.
Onchain Agent validates blockchain activity.
Neutral Agent synthesizes all viewpoints.
Execution Agent executes approved decisions.
This creates a robust investment committee rather than a single decision-maker.

Onchain analytics
Acts as committee chairperson.
Responsibilities:
Reviews all agent opinions
Resolves conflicts
Creates final consensus report
Produces execution recommendation
Responsible for:
Transaction preparation
Delegation usage
Relayer submission
Execution monitoring
The user connects MetaMask and upgrades their account into a Smart Account using MetaMask Smart Accounts Kit.
MetaMask creates:
Smart Account
Session Key
Delegated permissions
This eliminates the need for exposing private keys.
The user grants controlled permissions:
Examples:
Maximum daily spending limit
Approved protocols
Risk thresholds
Trading constraints
The AI can never exceed these limits.
The investment committee receives a portfolio objective.
Example:
"Invest $1000 with Moderate Risk."
Agents begin debating possible actions.
When additional information is required:
Agents autonomously pay for premium data.
x402 payment flows are triggered.
ERC-7710 delegated permissions authorize payment.
This allows agents to acquire premium intelligence without human intervention.
The Neutral Agent reviews:
Bull recommendations
Bear warnings
Yield opportunities
Onchain validation
A final committee decision is created.
Before execution:
Sentinel Policy Manager verifies:
Spending limits
Approved tokens
Risk thresholds
Governance rules
No transaction can bypass policy enforcement.
The approved transaction is submitted through the 1Shot Permissionless Relayer.
Benefits:
Gas abstraction
Stablecoin fee payments
Simplified UX
Automated execution
Execution occurs on Base Sepolia.
The Onchain Agent monitors:
Transaction success
Position updates
Portfolio state
Sentinel AI directly addresses this track through its specialized AI committee.
Implemented Agents:
Bull Agent
Bear Agent
Yield Agent
Onchain Agent
Neutral Agent
Execution Agent
Each agent has a unique responsibility and contributes to final decision-making.
Sentinel AI is fundamentally an Agent-to-Agent coordination platform.
Implemented Features:
Multi-agent debate system
Shared context passing
Consensus generation
Execution handoff
Delegation hierarchy
Agents communicate, challenge each other, and collaboratively arrive at decisions.
Sentinel AI implements:
MetaMask Smart Accounts
ERC-7715 Advanced Permissions
ERC-7710 Delegation
x402 Payment Flows
Agents autonomously pay for premium intelligence using delegated permissions without requiring user intervention.
Venice AI powers the reasoning layer.
Used For:
Investment analysis
Agent reasoning
Debate generation
Consensus support
Portfolio intelligence
Venice AI acts as the cognitive engine behind the committee.
Sentinel AI integrates:
1Shot Public Relayer
Gas abstraction
Stablecoin fee payments
Relayed execution
The Execution Agent submits approved transactions directly through the 1Shot infrastructure.
All contracts are deployed on Base Sepolia.

for enabling the next generation of autonomous onchain applications.
Started with a simple question:
"Can autonomous agents safely manage capital without requiring users to surrender control?"
Over the course of the hackathon, Sentinel AI evolved from a basic portfolio automation concept into a full multi-agent investment committee.
Major milestones achieved:
• Designed a Multi-Agent Consensus Architecture
• Implemented Bull, Bear, Yield, Onchain, Neutral, and Execution Agents
• Integrated MetaMask Smart Accounts
• Implemented ERC-7715 Advanced Permissions
• Implemented ERC-7710 Redelegation Flows
• Built Smart Account Governance Dashboard
• Developed x402-powered Research Layer
• Integrated 1Shot Permissionless Relayer
• Designed and deployed three core smart contracts
• Deployed frontend MVP
• Published technical documentation and architecture diagrams
• Created social media content documenting the entire build journey
The project progressed from architecture design to a fully functional end-to-end prototype demonstrating autonomous agent coordination, secure permission management, and onchain execution.
Sentinel AI is currently a hackathon-stage prototype and is not actively raising funds.
The primary focus is validating autonomous multi-agent portfolio management using MetaMask Smart Accounts, ERC-7715 permissions, ERC-7710 redelegation, x402 payments, and permissionless execution infrastructure.
Future fundraising may be considered after validating product-market fit and expanding cross-chain execution capabilities.
