Unibase Review 2026: Shared Memory for AI Agents

Unibase is an AI-agent infrastructure project built around shared long-term memory, with separate protocols for identity, payments and data storage. Membase is free to start and does not require a wallet, but pricing for paid services and completed audit details are not published.

Our verdict on Unibase

6.5/10

Unibase is most useful to people who want AI tools to share persistent memory, or developers building agents that need memory, identity or per-request payments. Membase is the clearest entry point: it is free to start, works through familiar AI interfaces and does not require a wallet. The main caveat is that important operational details remain unclear, including paid-service pricing, data-retention terms and completed audit results. Treat it as an emerging tool rather than assuming every protocol is equally mature.

What is Unibase?

Unibase is an AI-agent infrastructure project whose consumer-facing product is Membase, a shared memory service for tools including ChatGPT, Claude, Gemini, Grok, DeepSeek and Kimi. Users can access it on the web or through a browser extension, while developers can integrate memory through MCP, a REST API or SDKs. Unibase says Membase is free to start and does not require a wallet.

The project also offers AIP for agent communication and identity, Unibase Pay for x402 payments, Unibase DA for verifiable storage, and BitAgent for on-chain agents on BNB Chain and Base. These are presented as separate components rather than requirements for using Membase. The project does not publish full service pricing, detailed data-retention terms or completed audit results.

How Unibase works

Membase provides persistent memory that can be accessed across supported AI tools and agents. A user can work with the memory through the web app or extension, while developers can integrate it into their own software using MCP, a REST API or an SDK. Unibase says users can read and correct stored memory, and agents can be limited to named containers.

The other parts of Unibase are separate protocols. AIP handles agent communication and ERC-8004 identity; Unibase Pay uses x402 for per-request payments; and Unibase DA is intended to store data and provide availability proofs. The project says these components can be used independently, so using Membase does not by itself require a wallet, UB tokens or the other protocols.

6 features

Key features

Shared agent memory

Membase is designed to keep memories available across sessions and share them between supported AI tools. Users can access it through the web, a browser extension or developer interfaces.

Developer interfaces

Developers can connect through MCP, a REST API, or SDKs for JavaScript and Python. Unibase says these memory interfaces can be used separately from its identity and payment protocols.

Agent identity and interop

AIP combines agent-to-agent communication over A2A and MCP with ERC-8004 on-chain identity, permissioning and x402 payments.

Agent payments

Unibase Pay is designed for agents to discover and pay for resources per request through x402, without a user completing checkout for each transaction.

Verifiable data storage

Unibase DA is presented as a storage and verification network, with availability proofs settled on EVM chains. Unibase says its mainnet contracts are under audit and Base Sepolia is live.

On-chain agents

BitAgent lets users launch agents on BNB Chain and Base. The project says these agents can have ERC-8004 identities, persistent memory and access to an ERC-8183 service market.

Pros and cons

What we like

Membase is designed to share persistent memory across several named AI tools.
Users can begin with the web product without a wallet or UB tokens.
Developers have MCP, REST API and SDK integration options.
Identity, payments and storage are presented as independent protocols that can be added as needed.

Watch out for

Unibase does not publish detailed pricing for paid memory, API or agent services.
Its data-retention and privacy arrangements for stored memories are not clearly described.
Unibase DA mainnet contracts are under audit; completed audit results are not published.
The UB token is not required for Membase, so token holders should not assume the memory product creates demand for it.

Unibase fees

Membase is free to start, according to Unibase. The project does not publish a full fee schedule for paid memory, APIs, agent services or x402 payments. Unibase Pay is described as charging per request, but the amount depends on the resource or service; check the relevant product interface before using it.

Is Unibase safe?

Unibase says Unibase DA mainnet contracts are under audit and that Base Sepolia is live; it does not publish completed audit results in the product information. The project describes persistent memory and container-level access controls, but detailed storage, retention and privacy terms are not clearly set out. Treat stored documents and agent memories as sensitive data, and review the applicable product permissions before adding them.

Membase does not require a wallet to start, while the separate token and on-chain products involve blockchain and smart-contract risks. Unibase does not publish a licensing or regulatory status for these services. Unibase is not a gambling platform; any online gambling should be legal where you live and restricted to adults 18 and older, with responsible gambling practices.

6 steps

How to get started with Unibase

1
Choose whether you want to use Membase as a user or connect an agent as a developer.
2
For personal use, open Membase and create or access your account; Unibase says a wallet is not required to start.
3
Use the web app or browser extension to access shared memory with a supported AI tool.
4
For a custom agent, connect through MCP, the REST API, or a Membase SDK.
5
Add AIP identity or Unibase Pay only if your agent needs those separate functions.
6
Review any service pricing and data permissions before storing sensitive material or enabling paid agent requests.

Who Unibase is for

Unibase is aimed at AI users who want shared memory across multiple tools and developers who need persistent context or agent-to-agent features. People looking only for a simple chatbot may not need its broader identity, payment and storage protocols; teams handling sensitive information should first examine data permissions and retention.

Unibase FAQs

What is Unibase?

Unibase describes itself as an open memory layer for AI agents. Its Membase product lets users share persistent memory across supported AI tools, while separate protocols provide agent identity, payments and data storage.

Do I need UB tokens to use Membase?

No. Unibase says Membase is free to start and does not require a wallet or UB tokens. UB is used by node operators for staking and in governance.

How do I connect an AI agent to Membase?

Users can open Membase on the web or use its browser extension with supported AI tools. Developers can connect through MCP, a REST API or the Membase SDKs.

How do Unibase agent payments work?

Unibase Pay uses x402 for per-request payments, and the project says payments settle on BNB Smart Chain and Base. It does not publish the fees users may pay for individual services.

Which AI tools work with Membase?

Unibase names ChatGPT, Claude, Gemini, Grok, DeepSeek and Kimi as supported tools for shared Membase memory. Check the current Membase interface for the integrations available to your account.

Is Unibase a gambling platform?

Unibase is not a gambling service. For any online gambling, check that it is legal where you live, and only participate if you are 18 or older; gamble responsibly.
