The native TRON REST API (`wallet/getnowblock`, `wallet/triggersmartcontract`) is out of scope for this bench; a chain-specific `tron-rest` bench can be added later when there is clear demand from integrators using TronWeb directly.","Chain scope: every query on this page is pinned to `chain=\"tron\"`. Provider coverage: 2 no-key public-read endpoints live today, each listed with its URL in the endpoints table on this page. dRPC removed (method not available). The TRON JSON-RPC provider market is materially smaller than the EVM one; most TRON infra vendors expose only the native TRON REST API keyless, and gate the JSON-RPC path behind an API key.","Excluded by the launch audit: dRPC (method not available), Ankr (key required on tron_jsonrpc path), Chainstack / NOWNodes / GetBlock / Tatum / BlockPI (key required on JSON-RPC path), OnFinality + Blast API + AllThatNode (no public TRON JSON-RPC gateway), Tron Foundation's rpc.trongrid.io (DNS dead; correct host is api.trongrid.io/jsonrpc)."],"license":"CC-BY-4.0"}
