Grindery separates the smart wallet client from the infrastructure, enabling dApps to integrate shared, self-custodial, multichain wallets just like EOAs—open, portable, and permissionless.
Grindery is not just another Wallet-as-a-Service (WaaS). We are introducing a fundamental shift in how wallets interact with decentralized applications. Instead of treating wallets as closed systems tied to specific dApps, Grindery provides a shared, self-custodial smart wallet infrastructure that any developer can integrate into their applications.
This document explains how Grindery differs from traditional EOAs (Externally Owned Accounts) and existing WaaS offerings, and why this shift is essential for the next generation of decentralized applications.
The Problem with Existing Wallet Models
1. EOAs (Externally Owned Accounts)
- EOAs are the standard in Web3 today, but they come with significant limitations.
- Users are responsible for managing private keys, leading to lost funds and high friction in onboarding.
- No built-in automation, making smart contract interactions cumbersome.
- Every wallet is tied to a specific key, and there is no way to recover access if lost.
2. Traditional WaaS Offerings
- WaaS solutions allow dApps to create wallets for users, but these wallets are tied to the dApp itself.
- Users cannot carry their wallet between different dApps unless the provider allows it.
- Most WaaS providers either own the wallets (custodial) or require significant integration work.
- Wallets created with one WaaS provider cannot be reused in another without rebuilding the user experience.
The Grindery Approach: Public Smart Wallet Infrastructure
Instead of offering a closed, dApp-specific wallet service, Grindery is building a permissionless, censorship-resistant public infrastructure that allows any developer to embed a fully self-custodial, multichain wallet into their dApps—whether on web, Android, or iOS.
Key Differences
Feature | EOAs | Existing WaaS | Grindery |
User Control | Full control but high risk (private keys) | Varies (usually custodial or app-restricted) | Full control with smart recovery options |
Wallet Portability | Yes (but tied to private keys) | No (wallets are app-specific) | Yes (shared infrastructure, any app can integrate) |
Security Model | Seed phrases, manual backups | Custodial or app-managed recovery | Smart contract-based recovery, deterministic ID |
Developer Flexibility | Requires deep blockchain knowledge | Requires WaaS API integration | Completely open infrastructure, any app can embed a wallet |
Gas Fees | Users pay for transactions | Depends on WaaS provider | Gasless transactions via smart contract abstraction |
Multichain Support | Requires multiple wallets | Limited to supported chains | Supports both EVM and non-EVM chains (e.g., TON, Solana, etc.) |
How Grindery Works
1. Infrastructure vs. Client Separation
- Grindery separates the wallet infrastructure from the client interface.
- dApp developers embed Grindery wallets into their own applications, just like they would with EOAs—but without the complexity.
- The wallet remains self-custodial and is not tied to a single dApp.
2. Shared, Self-Custodial Smart Wallets
- Unlike existing WaaS offerings, Grindery does not own or restrict wallet usage.
- Any dApp can integrate the same wallet infrastructure, allowing users to interact across multiple applications without re-creating wallets.
3. Deterministic Social ID for Wallet Generation
- Wallet addresses can be deterministically generated from a user’s Telegram ID, email, or other social identities.
- This allows developers to onboard users without forcing them to manage seed phrases.
- If desired, dApps can use Grindery’s API to simplify this process.
4. Gasless Transactions & Smart Recovery
- Users can interact with multiple chains without needing native gas tokens.
- Wallets support automated recovery options without custodial control.
5. Open & Extensible Architecture
- dApps can integrate any existing DeFi or dApp marketplace instead of being locked into a predefined suite of services.
- Developers can use WebViews, third-party dApps, and custom-built integrations.
Why This Matters for dApp Developers
1. Unlocking True Web3 UX
- No more onboarding users with complex seed phrases.
- No need to force users to switch wallets between dApps.
- Gasless transactions simplify the user experience.
2. Build Once, Deploy Anywhere
- Use the same wallet infrastructure across multiple dApps.
- Supports web, Android, iOS without fragmented solutions.
- dApps can integrate TON, Ethereum, Polygon, and more.
3. Permissionless & Censorship-Resistant
- Unlike centralized WaaS providers, Grindery is public infrastructure.
- No API lock-in—dApps can interact without Grindery’s backend if desired.
- Users always have control over their assets.
Wallet Clients
Grindery Wallets Clients are consumer-facing smart wallet application built on the Grindery platform, a permissionless infrastructure for self-custodial, multichain wallets. Unlike traditional wallets, Grindery Wallet is not tied to a single application or provider—it is a modular client that interacts with an open, shared wallet infrastructure.
Separation of Layers: A Flexible, Open Approach
The Grindery Wallet operates on a clear separation between the wallet client and the underlying infrastructure, similar to how EOAs interact with blockchains:
- Grindery Infrastructure → A decentralized backend for managing smart wallets, ensuring portability, self-custody, and security.
- Grindery Wallet Client → A user-friendly application that integrates with this infrastructure, providing a seamless interface for end users.
Key Technical Advantages
✅ Self-Custodial by Design – Users own their wallets, with smart recovery options and no centralized control.
✅ Modular & Extensible – Developers can integrate Grindery-powered wallets into their own applications, or build custom clients.
✅ Multichain Support – Built for EVM and non-EVM blockchains, ensuring seamless asset interactions.
✅ AI-Powered Automation – Smart workflows, gas abstraction, and contextual intelligence enhance the user experience.
By separating the wallet logic from the application layer, the Grindery Wallet serves as an example of what’s possible—but it is just one implementation. Developers can embed the same smart wallet infrastructure into their own apps while ensuring users retain full control over their assets
