# One API key, every chain.And an agent that can use it.

RPC endpoints, token and NFT data, smart wallets, and webhooks — reached the same way whichever chain you are on. Reading a balance on Ethereum and reading one on Solana are the same call with a different argument, so the chain becomes a parameter instead of a rewrite. The same calls are exposed as tools, so an agent can make them too.

## The pieces

Each one answers a question you would otherwise run a node to answer. They share a key, an address scheme, and a chain argument, so reaching for a second one costs you a line.

## What sits behind the key

An app that touches a chain ends up needing most of this — a node to read from, somewhere to keep keys, a way to hear about a transaction that already happened. Open a group to see what it covers.

### Blockchain Nodes & Data

Read a chain without running a node for it

### Wallet & Key Management

Where the keys live, and what has to happen before one signs

### On-Chain Payments

Take a stablecoin the way you would take a card

### Smart Contract Management

Ship a contract to several chains and keep track of what you shipped

### Decentralized Storage

Persistent, censorship-resistant data storage

### Oracle Services

Bring off-chain data on-chain

### Blockchain Indexing

Ask a question a chain cannot answer in one call

### Cross-Chain Infrastructure

Bridge assets and data between chains

### Compliance & Fiat

Enterprise compliance and fiat rails

Unified Platform

## An agent withan address.

These calls are exposed as tools, so an agent can make them the way you would. It reads a balance, builds a transaction, and signs under whatever policy you put on the key — the same policy that governs a person. What an agent may spend is a rule on the wallet, not a promise in a prompt.

- AI agents that can send on-chain transactions
- Natural language smart contract interaction
- Automated DeFi strategies with AI optimization
- Cross-chain portfolio management

hanzo-agent.ts

```
import { Hanzo } from "@hanzo/ai"; import { Wallet } from "@hanzo/blockchain"; const agent = new Hanzo.Agent({ model: "claude-sonnet-4-6", tools: [Wallet.tools], }); // Agent can now execute on-chain await agent.run(` Check my ETH balance on Ethereum mainnet, then swap 0.1 ETH for USDC on Uniswap if the price is favorable. `);
```

## The chains

Adding one is our work, not yours — the call you already wrote takes a different argument.

## Make the first call

A key from the console reaches the RPC endpoints, the token and NFT data, the wallets and the webhooks. Pick a chain and read something. No credit card required.
