Add WelshDAG public RPC for BlockDAG Network (1404)

[Welshdag]

Summary

Adds the WelshDAG-operated public RPC endpoint for BlockDAG Network, chain ID 1404, using the current extraRpcs.js schema.

• RPC: https://rpc.welshdag.trade
• Chain ID: 1404
• Hex chain ID: 0x57c
• Operator: WelshDAG
• Transport: HTTPS through Cloudflare

The endpoint is marked tracking: "limited" because Cloudflare and WelshDAG infrastructure may log IP addresses, RPC methods, timestamps, and request metadata for rate limiting, abuse prevention, security, and service reliability. The published data-handling terms are linked in the RPC entry.

Link the service provider's website (the company/protocol/individual providing the RPC):

https://welshdag.trade

Provide a link to your privacy policy:

https://welshdag.trade/rpc-privacy/

The policy explains the RPC's limited operational logging, purposes, service providers, retention criteria, user choices and contact route.

If the RPC has none of the above and you still think it should be added, please explain why:

This community-operated endpoint provides an additional independent public RPC for BlockDAG users. It requires no API key, supports browser CORS, and is intended to remain publicly available.

Validation

Public checks completed on 28 July 2026:

• RPC HTTP status: 200
• CORS: Access-Control-Allow-Origin: *
• eth_chainId: 0x57c
• eth_blockNumber: returned a valid current block height
• No API key required
• Privacy policy: HTTP 200 across repeated cache-busted requests
• Privacy policy is linked from the WelshDAG homepage

Repository checks:

• node --check constants/extraRpcs.js — passed
• git diff --check — passed
• Two focused commits and one changed file
• The 1404 RPC is appended at the end of the extraRpcs object
• The tracking details include the published privacy-policy URL

The repository test script reproduces three existing failures on the untouched upstream baseline: octal-escape parsing in extraRpcs.js and chainIds.js, plus duplicate chain key 4663. This change introduces no duplicate 1404 key.

Hi maintainers — this RPC submission is ready for review. The endpoint, CORS, chain ID and published privacy policy have been verified, and the repository validation check passes. Please let me know if any changes are required. Thank you.
