Stackup is an enterprise-grade Web3 platform for managing digital assets and automated smart accounts. Built on the concept of Account Abstraction (ERC-4337), the project offers businesses a secure, scalable, and flexible solution for managing multichain assets, integrating with banks, and automating onchain payments. Thanks to a team with experience at SpaceX, Coinbase, and the Ethereum Foundation, Stackup delivers enterprise functionality with the security standards of decentralization.

Stackup Concept and Key Features
Stackup builds a digital infrastructure for organizations that want to manage their crypto assets at an enterprise level. Unlike personal wallets, Stackup implements role-based access control, automated approval flows, and support for multichain environments. Companies can assign roles (accountant, CFO, administrator), each with specific permissions for asset interaction.
Stackup eliminates the need for employees to store private keys — instead, passkey and WebAuthn authentication is used. The platform also includes its own gasless transaction system, which is crucial for organizations conducting dozens of transactions daily. It is fully compatible with major L2 and EVM-compatible networks, including Ethereum, Arbitrum, Base, Polygon, and others.
Platform Architecture and the Role of Account Abstraction
At the core of Stackup are smart contract wallets powered by Account Abstraction. By using the ERC-4337 standard, key operations like authentication, role verification, and gas payments are moved into the smart contract layer, enabling more flexible access control.
Stackup provides infrastructure that includes:
- Smart wallets managed via WebAuthn keys
- Its own paymaster service covering gas fees
- Support for multisignature and conditional automation
- Compatibility with existing apps via API
From a technical standpoint, Stackup ensures high performance, advanced transaction logic, and continuous contract upgrades with backward compatibility. As a result, the platform offers ERP-level control — but in an onchain environment.
Security, Audit, and Role Management
Stackup focuses on institutional-grade protection and compliance with industry standards. The platform undergoes audits and is preparing for SOC2 Type II certification. Its smart contracts are based on OpenZeppelin libraries and are regularly tested for vulnerabilities.
| Component | Description |
|---|---|
| Authentication | Login via Passkey/WebAuthn, no private keys |
| Access Control | Role-based access and permissions |
| Contract Security | Audits, unit tests, based on OpenZeppelin standards |
| Recovery Options | Access recovery through trusted recovery mechanisms |
| Frontend Protection | Resilient even if UI is compromised (frontendless architecture) |
Stackup’s model ensures that even if the frontend is compromised, asset management remains under user control due to its decentralized architecture. This guarantees long-term security in enterprise operations.
Ecosystem and Strategic Partnerships
Stackup is evolving within a vibrant multichain ecosystem, covering both Web3 environments and traditional fintech sectors. Strategic alliances and diverse integrations help the project build a robust infrastructure adaptable to organizations of any size.
- Coinbase Wallet — ERC-4337 infrastructure implementation
- Trust Wallet — uses Stackup as a backend engine
- Supports Ethereum, Arbitrum, Optimism, Base, Polygon, BNB Chain
- Banking system integration (ACH technology)
- Partners: Y Combinator, 1kx, DCG, Goodwater Capital
- Team: ex-SpaceX, Afterpay, MIT, Ethereum Foundation
Stackup’s partner model targets long-term development and includes both decentralized applications and enterprise platforms. This makes Stackup not just a tool but a true infrastructure hub bridging TradFi and Web3.
Funding, Roadmap, and Development Outlook
Stackup is attracting growing interest from venture capital firms and institutional investors. This is driven not only by the quality of the product but also its relevance in the era of corporate finance digitalization. The project already demonstrates resilience and adaptability.
- Scaling ACH-linked wallet banking integrations
- Expanding its proprietary gas payment system (Paymaster API)
- Broader multichain support
- Security certifications (SOC2, etc.)
These steps reinforce Stackup’s technical foundation and open the way to scalable B2B Web3 solutions. In the coming months, the team will focus on international expansion, onboarding new enterprise clients, and deepening third-party API integrations.
