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.

Unified Platform

An agent with
an 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.

const agent = new Hanzo.Agent({

// 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.
