RPC Boundary

The HTTPS endpoint exposes bounded read, query, wallet, relayer, and raw transaction access for the public Core. Raw endpoint links are developer tools; readable status pages remain the normal visitor path.

How to use this boundary

Start with the readable pages, then open raw endpoints only when you need exact JSON for tooling or debugging.

Readable first

Use Status, Blocks, Ledger, Network, and Validators pages for quick checks without parsing raw responses.

Developer JSON

Endpoint links expose public Core responses for tools, mirrors, and wallet compatibility checks.

Gateway only

Public clients should use https://core.uquad.org for readable pages and https://core.uquad.org/rpc for JSON-RPC tooling. Node-local listeners and operator paths are not public surfaces.

Monitor method

GET is the canonical public-read method for JSON health checks. HEAD is optional and a 405 response on gateway-backed JSON paths is not, by itself, an outage.

Public Core boundary

Live CometBFT reads, wallet REST/LCD, the Core-owned static index, relayer JSON-RPC, WebSocket events, and raw transaction broadcast are separately bounded. Website root JSON-RPC POST remains blocked.

Allowed

/status, /health, /net_info, /block, /block_results, /validators, /abci_query, /abci_info, /tx, /genesis, /commit, and /blockchain.

Wallet API

/api is the Cosmos REST/LCD boundary for Keplr and compatible wallet tooling. Most custom Core module queries are not mapped to HTTP; use the observatory's /index/*.json feeds for browser-readable Core state.

\n
Public index

/index/*.json is produced server-side from Core query surfaces and carries freshness, evidence class, and boundary labels. It is a projection, not a second authority.

Relayer RPC

/rpc, /rpc/status, and /rpc/websocket mirror the Bridgechain public RPC shape for JSON-RPC clients and relayer tooling.

Broadcast open

/broadcast_tx_sync, /broadcast_tx_async, and /broadcast_tx_commit are open for raw Core transaction submission with gateway rate limits.

Not exposed

The node-local CometBFT RPC listener remains behind nginx. Public clients should use the listed gateway paths only.

ABCI endpoint response

Developer-surface JSON from /abci_info. It is public Core data, not a wallet or claim path.
