[ RPC · chain 2222 ]

kava, with proofs.

JSON-RPC for kava through one gateway over 3 measured endpoints. Every answer carries a receipt; a proved read adds the block proof under the superroot.

[ Agents ]

Quick MCP

Connect an agent to the layer in one line. The MCP server answers without a key; its taifoon_register tool issues one.

claude mcp add --transport http taifoon https://coord.taifoon.dev/mcp

First call from any MCP client: tools/list, then taifoon_proof_tx with a chain and a transaction hash.

[ Partnership ]

Run kava with Taifoon

A chain or protocol team can claim the owner seat of its record: it then maintains its lanes and stage table, sets its pricing share, and the Conclave records the ownership and the share. Endpoint operators can add capacity to the rotation and earn per call.

curl -s https://coord.taifoon.dev/v1/owners/chain:2222

Claim: POST https://coord.taifoon.dev/v1/owners/chain:2222/claim with your key and a signature from an address your contracts name. Partner cards · add capacity.
