PermiSIP is an AI based aggregated SIP which invests across various Defi protocol using MetaMask Advanced Permissions to enable secure, automated investing.
Building a reliable SIP in DeFi is hard for most users.
Users need to research multiple DeFi protocols, compare yields and risks, decide allocations, and manually execute transactions on a recurring basis. This process is time-consuming, complex, and easy to get wrong.
Existing automation solutions either require repeated wallet approvals or demand broad wallet access, which introduces security risks and breaks user trust.
PermiSIP AI simplifies DeFi SIPs by combining AI agents with MetaMask Advanced Permissions.
Users start by defining an investment goal, such as saving a fixed amount over time. AI agents analyze different DeFi protocols and generate a clear SIP plan that includes investment frequency, allocation, and maximum spend limits.
Before activation, users explicitly review and approve the plan. Instead of granting full wallet access, they approve scoped MetaMask permissions that strictly control what the system can do. Once approved, SIPs execute automatically on a fixed schedule without repeated wallet popups.
This allows users to automate long-term investing while retaining full control over their funds.
PermiSIP AI makes deliberate use of two types of MetaMask Advanced Permissions, each serving a distinct role.
MetaMask Spend Permissions are used for the SIP execution layer.
They allow the smart contract to spend a fixed amount per month for the SIP, limited to a specific token and contract. This ensures that monthly investments can run automatically while enforcing strict spending caps and time bounds.
MetaMask Stream Permissions are used for the AI agent layer.
They allow AI agents to operate continuously in the background—planning, monitoring, and coordinating SIP execution—without requiring repeated user interaction. These permissions enable agents to function autonomously while remaining fully constrained by the user’s approved scope.
AI agents are designed as a decision-only layer:
A Basic Agent orchestrates SIP planning and execution
Advanced Agents handle risk analysis, yield evaluation, and protocol selection
Agents never directly access or custody funds
All financial logic and state live in the smart contracts deployed via MetaMask Smart Accounts on supported EVM networks. Users can revoke permissions at any time, ensuring safety and transparency.
During the hackathon, we focused on building a working, end-to-end prototype that demonstrates the real value of MetaMask Advanced Permissions. What we implemented: 1. MetaMask Spend Permissions to enable automated, monthly SIP executions with predefined limits 2. MetaMask Stream Permissions to allow AI agents to operate continuously without repeated user interaction 3. A goal-based SIP creation flow powered by AI agents 4. On-chain smart contracts as the source of truth for SIP execution 5. Automated execution using scheduled triggers without wallet popups
