# Altana Network

> Altana gives every AI agent a Smart Agentic Wallet that acts on any open protocol. One integration, entirely self custodial: the owner sets the rules and can revoke them at any time. Live on mainnet across BNB Chain, Ethereum, and Base, with the same wallet address on every chain.

Altana is operated by Serendipity Global Inc., a Delaware corporation doing business as Altana Network. The Altana protocol itself is an open, self custodial authorization protocol made of open source smart contracts deployed on permissionless public blockchains. Anyone may interact with the deployed contracts directly, without using Altana's interfaces.

Altana never takes custody of funds or keys. Permissions are verifiable, revocable, and owned by no vendor. One permission works across BNB Chain, Ethereum, and Base.

## The three layers

- Account layer, Smart Agentic Wallet + Keystore: a noncustodial account for every agent, and a neutral registry of exactly what each agent may do. Verifiable by anyone and instantly revocable by the owner.
- Integration layer, SDK + MCP: a TypeScript SDK and an MCP server that plug straight into AI hosts like Claude and Cursor. An agent transacts in minutes, not months.
- Execution layer, Intent relay: turns an agent's intent into an executed transaction. Every action is simulated before signing, with gas handled for the user.

## What the Keystore is

The Keystore is a neutral registry of agent permissions, recorded onchain and owned by no one. Other platforms keep authorization inside their own backend; Altana puts it where everyone can see it.

- Any app can check what an agent is allowed to do, even one that has never heard of Altana. No integration, no API key.
- One permission works across BNB Chain, Ethereum, and Base.
- Never locked to a vendor, including Altana.

A permission record carries the things an owner actually cares about: which agent, a spend cap such as 250 USDC per day, an allowlist of approved apps or contracts, the chains it is valid on, and a validity window that lasts until the owner revokes it. Revocation takes one transaction and takes effect before the agent's next action.

## Who it is for

**Platforms hosting agents.** Let every agent on your platform transact. Give thousands of agents the power to pay and operate without building wallet and permission infrastructure in house, and without taking custody. Integration is free, with no usage tiers. Neutral, verifiable, and free of lock in.

- 1 integration: one Keystore scales permissions across an entire fleet of agents.
- 0 custody: Altana never holds funds. Liability stays bounded by the limits each owner sets.
- Instant: any permission, revoked in one call, effective before the next action.

**Builders.** Start in minutes, not months. Install the SDK, set your limits, and your agents transact. It plugs into what you already run, from your own platform to hosts like Claude and Cursor. Your keys stay yours; Altana never takes custody.

## Install

Install the TypeScript SDK:

```
npm install @altananetwork/sdk
```

Or add the MCP server to an AI host such as Claude or Cursor:

```json
{
  "mcpServers": {
    "altana": {
      "command": "npx",
      "args": ["@altananetwork/mcp"]
    }
  }
}
```

## FAQ

**Who is Altana for?**
Platforms building for AI agents. If your product hosts agents that need to hold and move money, Altana gives every one of them an agentic wallet with limits their owner sets, so you never build wallet and permission infrastructure in house or take custody.

It also works for builders who want the agents they already run, like Claude and Cursor, to transact for them.

**What is the Keystore?**
The place where every agent's permissions live. It is a neutral registry recorded onchain, owned by no one and readable by anyone, so any app can check what an agent may do without integrating anything.

**Does Altana hold my funds or keys?**
No. Altana is noncustodial. Your keys stay yours, and Altana never sees them.

**What can an agent actually do?**
Exactly what you allow. You choose what it can spend, where it can act, and until when. Every action is checked against those limits onchain before it executes.

**What if an agent goes rogue or gets manipulated?**
It cannot act beyond the limits you set. You can revoke any permission instantly, the effect is immediate, and every transaction is simulated before it is signed.

**Which chains and AI hosts does Altana support?**
Altana is live on mainnet across BNB Chain, Ethereum, and Base, with the same wallet address on every chain. It reaches your agent through MCP hosts like Claude and Cursor, or directly through the TypeScript SDK.

**How do I get started?**
Install the SDK or the MCP server, connect your agent, and set your first limits. It takes minutes.

## What we believe

- Control: people stay in command. Agents act only within limits their owner sets, changeable at any moment.
- Security: safe by design. We protect what people put in an agent's hands by default, never as an afterthought.
- Built for people: product first. We understand the person behind the agent and build technology that serves them.
- Freedom: we automate what can be automated, so people spend their time on what matters.
- Openness: infrastructure that answers to its users, never locked to a single platform.
