Tech Framework

GearFlow – Technical Framework

A secure transaction layer between users and dApps, powered by Mediator Contracts.

GearFlow is the fourth core component of the GearUp ecosystem. It is a mobile app and browser plugin designed to enable secure interaction between users and external dApps through self-deployed mediator contracts. Unlike traditional wallets, GearFlow prevents users from exposing their main wallet to risky third-party contracts.

With GearFlow, every dApp interaction is proxied through contracts built in GearUp Studio or Factory, giving users complete control, transparency, and isolation.

🔐 What Problem Does GearFlow Solve?

Most DeFi users unknowingly approve access to unverified contracts via wallets like MetaMask or TrustWallet. Once a single contract is compromised, your funds are at risk.

GearFlow introduces an abstraction layer that lets users:

• Deploy and interact via their own mediator contracts

• Avoid direct wallet-to-dApp permissions

• Log and restrict function-level access

• Track and revoke privileges from a unified dashboard

⚙️ How GearFlow Works

1. Users create a Mediator Contract via GearUp Studio or Factory

2. Contract is deployed and registered in the GearFlow app

3. When connecting to a dApp, the user connects via the GearFlow Plugin, which acts as a contract signer, not a wallet signer

4. All contract interactions are passed through the user’s Mediator Contract which executes the final on-chain transaction

[User Wallet] -> [Mediator Contract] -> [Target dApp/Contract]

The dApp never interacts with the user's wallet directly.

🧱 Mediator Contract Architecture

Mediator contracts are:

• Customizable

• Stateless or stateful (optional session tracking)

• Compatible with token spending, swaps, staking, lending, and more

• GearUp Template-powered

Sample Modules

• approveTokenSpender() with timeout

• proxyCallWithRevertCheck()

• batchExecute(address[] targets, bytes[] data)

Each GearFlow-compatible mediator comes with audit-grade patterns:

• Reentrancy guard

• Parameter validation

• Access scope limiting

📱 GearFlow App (Mobile)

• Available for Android + iOS

• Supports WalletConnect + custom RPC

• Built-in mediator deployment and management

• Transaction history, notifications, and privilege tracking

• QR-code based login for contract session initiation

---

🧩 GearFlow Plugin (Browser Extension)

• Intercepts WalletConnect and dApp connect attempts

• Routes actions through selected Mediator Contract

• Simulates and previews function calls before execution

• Uses deterministic session hashes

• Logs all outbound calls and ABI signatures

{
  "action": "swap",
  "contract": "0xabc...def",
  "function": "swapExactETHForTokens",
  "status": "simulated",
  "result": "low slippage; execution safe"
}

---

🔐 Security Highlights

• No private key exposure beyond GearFlow layer

• 100% on-chain execution traceable from user to dApp

• Permissions can be auto-expiring or revocable

• Emergency contract pause available from app

• Open source templates available for audit

🌐 Future Vision

• Session approval via multisigs

• Modular contract stacking (for DAOs, bots, vaults)

• AI-assisted mediator setup via Scrappy

• Real-time fraud detection before transactions

GearFlow lets you use any dApp without giving up wallet control.

Think of it as a firewall for your DeFi identity — a programmable contract proxy that acts with your rules, not theirs.
