feat(rpc): add NOWNodes to ethereum-rpc and bnb-rpc - #2283
Merged
Conversation
NOWNodes exposes keyless public endpoints on a handful of chains. Tested apples-to-apples from the VPS with the harness's own eth_getBlockByNumber probe: public-eth.nownodes.io p50 38ms / head lag 0 blocks vs publicnode, public-bsc.nownodes.io p50 100ms / head lag 0 blocks. Both fresh, both under the 5 RPS free limit at the harness's 3-req/min cadence. Their other public endpoints don't fit an existing bench: Coreum returns 501 on the Tendermint /status our cosmos probe uses (only the gRPC-gateway REST works), and LUKSO/Bitcoin have no bench. A full scan of public-<ticker>.nownodes.io across every RPC bench chain confirmed only eth, bsc, coreum and lukso answer keyless. Adds nownodes to the harness config for those two chains, the provider block in both specs, and enriches the registry entry. Co-Authored-By: Claude Opus 4.8 <noreply@anthropic.com>

Config half of the NOWNodes onboarding (dev PR #2283 carries the specs and registry). Adds the keyless public-eth / public-bsc endpoints so the Railway rpc-capabilities services start emitting provider="nownodes" into Prom. Verified fresh and fast against publicnode before shipping.

Adds NOWNodes as a keyless provider on the two benches where their public endpoints fit our existing probe.
