MonadAutomated DeFi Yield
Optimization on Monad
Synapse Yield leverages Account Abstraction and MetaMask Delegation to automate yield optimization across DeFi protocols with institutional-grade security.
DeFi Complexity Hinders Growth
- Manual yield tracking & rebalancing across diverse protocols is inefficient and complex.
- Executing multiple transactions for DeFi actions wastes time and valuable gas fees.
- Managing varied interactions increases security risks and operational burdens for users.
Effortless & Secure Yield
- Automated Strategy Execution: Backend agent monitors protocols and executes pre-approved strategies to optimize portfolio balance and yield.
- Non-Custodial Security: Securely delegate limited permissions (stake, swap, approve) via MetaMask Delegation, retaining full asset control.
- Simplified UX (AA): Smart Accounts enable one-click actions, transaction batching, and potential gas savings through paymaster integration.
Platform Capabilities
Enterprise-grade infrastructure for automated DeFi yield generation
Smart Account Abstraction
Leverage ERC-4337 Smart Accounts (via Pimlico & permissionless.js) for enhanced UX, transaction batching, and enabling automated actions.
Non-Custodial Delegation
Securely grant scoped permissions using MetaMask Delegation Toolkit, allowing automated actions without compromising private key security.
Automated Yield Optimization
Enable the optional keeper service (runs via Cron) to automatically monitor yields and rebalance assets between integrated protocols for optimal returns.
One-Click DeFi Actions
Perform staking, unstaking (standard & instant via swap), and token swaps through the delegated Smart Account with a single confirmation.
Simplified Fund Management
Easily transfer assets (MON, ERC-20 tokens) between your wallet (EOA) and your Smart Account.
Real-Time Activity Feed
Track both your Smart Account's actions and public protocol events (stakes, swaps) using real-time data indexed by Envio GraphQL.
How It Works
Get started with automated yield optimization in three simple steps.
01
Connect & Deploy
01
Connect & Deploy
Easily connect your existing MetaMask wallet and Sign-In. With a single click, a new, secure Smart Account is derived and prepared for you, laying the foundation for all automated and one-click actions on the platform.
02
Fund & Delegate
02
Fund & Delegate
Transfer assets into your new Smart Account. Then, sign a one-time message to create a secure, non-custodial delegation. This grants our automated keeper limited, specific permissions to act on your behalf without ever exposing your keys.[Do a token transfer from your Smart Account to make sure it gets properly Deployed on-chain]
03
Optimize Returns
03
Optimize Returns
Toggle on the automation service to let the keeper rebalance your portfolio for optimal yield. You can also manually perform one-click staking, unstaking, and swaps, all while tracking real-time performance and on-chain activity.

Technology Stack
Built on a foundation of cutting-edge, secure, and scalable technologies.
MetaMask Delegation
Utilizes the Delegation Toolkit for secure, non-custodial automation, enabling scoped permissions without exposing private keys.
Account Abstraction
Built on ERC-4337 Smart Accounts, orchestrated with permissionless.js for transaction batching and enhanced UX.
Pimlico
Leverages Pimlico's enterprise-grade Bundler and Paymaster for reliable UserOperation execution on the Monad Testnet.
Next.js
A modern, performant frontend built with the Next.js App Router, serverless functions, and TypeScript for a seamless user experience.
Wagmi & Viem
Provides robust, type-safe React hooks and low-level utilities for all blockchain interactions, ensuring stability and reliability.
SIWE & Iron Session
Implements secure, server-side authentication using Sign-In With Ethereum (SIWE) and encrypted session management with Iron Session.
MongoDB
Stores user data, including delegation details and automation preferences, using Mongoose for structured and scalable data management.
Envio
Provides high-performance, real-time data indexing from the blockchain via a custom GraphQL API for the live activity feed.
FastCron
Reliably triggers the serverless keeper function on a schedule to perform automated portfolio rebalancing for opted-in users.
Non-Custodial by Design
Our multi-layered security architecture is built on battle-tested, decentralized principles to ensure you always have complete control over your assets.
Non-Custodial Asset Control
Your assets never leave your Smart Account. You retain 100% ownership and control via your personal MetaMask wallet.
Zero Private Key Exposure
Your private key never leaves your wallet. All interactions, including login and delegation, are authorized using secure cryptographic signatures.
Scoped & Granular Delegation
Using MetaMask Delegation, you grant limited, specific permissions to our automated keeper (e.g., 'approve' or 'stake'), never full account access.
Secure Authentication (SIWE)
We use Sign-In With Ethereum (SIWE) for wallet-based login, ensuring that only you can access your account data and settings.
Encrypted Session Management
All user sessions are encrypted and managed server-side using Iron Session, protecting your session from hijacking and unauthorized access.
Testnet to Mainnet Evolution
Currently demonstrating core concepts on the Monad Testnet with a clear path to production-grade functionality.
Protocol Scope
Limited to Kintsu & Magma for demonstration
Extensible to all high-yield protocols on the network
APY Data Source
Simulated values for demonstration purposes
Live on-chain data from protocols & oracles
Rebalancing Strategy
Basic 50/50 portfolio ratio balancing
Advanced, dynamic rebalancing based on live APY & gas costs
Transaction Model
Sequential UserOperations (one per action)
Atomic batching (e.g., approve + stake in one UserOp)
Gas Fee Management
Sponsored via Pimlico's Testnet Paymaster
User-funded with advanced gas optimization strategies
Automation Trigger
Centralized Vercel Cron Job
Decentralized keeper networks (e.g., Chainlink Automation)
