[ RPC · chain 137 ]

Polygon, with proofs.

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

Writes: transaction sends are being added through the streaming settle path; until then eth_sendRawTransaction is refused with a named reason. Limits and prices: below.

[ 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.

[ Data subscriptions ]

Stream what happens on Polygon

The producer follows these protocols on Polygon: layerzero_v2 · u_demo_counter. Register a project scoped to the chain, then stream it or take its webhook.

curl -s -X POST https://coord.taifoon.dev/v1/projects -H "X-API-Key: $KEY" -H 'content-type: application/json' -d '{"id":"my-polygon","name":"My Polygon watch","protocols":["layerzero_v2"],"filters":{"chains":[137]}}'

[ Partnership ]

Run Polygon 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:137

Claim: POST https://coord.taifoon.dev/v1/owners/chain:137/claim with your key and a signature from an address your contracts name. Partner cards · add capacity.
