Build

Live today.
More on the way.

A clear line between what works now and what is still being built — plus how to call the gateway from your own code.

01 · Status

What is live today.

Live

Read the chain

Balances, tokens, blocks, transactions, logs, bytecode, storage and contract calls.

Live

Simulate transactions

Dry-run any transaction and get the unsigned result to sign yourself.

Live

Seven networks

Ethereum, Base, Arbitrum, Optimism, Polygon, BNB Chain and Robinhood Chain.

02 · Roadmap

What comes next.

These are planned, not shipped. They will be listed under Status only once they work.

Planned

Deploy from a prompt

Start from reviewed templates, compile, estimate gas, deploy and verify — with you signing the deployment.

Planned

Agent wallets with limits

A separate wallet for autonomous agents, with session keys, spend caps, allow-listed contracts and an expiry.

Planned

Verified source lookup

Fetch verified contract source and ABIs so your AI can explain what a contract does, not just call it.

Planned

More networks

Each new chain gets the same tools and the same endpoint.

03 · For developers

Call the endpoint directly.

The endpoint is plain JSON-RPC over HTTP (MCP Streamable HTTP, stateless). You can use it from any language without an MCP library.

List the tools

curl -s https://www.nerbyprotocol.xyz/mcp \
  -H 'Content-Type: application/json' \
  -d '{"jsonrpc":"2.0","id":1,"method":"tools/list"}'
