Hey @MyRxWallet, thanks for you contribution!
Unfortunately I can't approve this PR:

1. affected lines include unprompted JSON formatting changes. Please add or change information for you chain ID only
2. Frontend behind the explorer URL is not a full featured explorer
3. Blockscout is used as an indexer but there are no attribution mentioned in the provided URL, Our license obliges users to mention Blockscout when used.

Hi @NikitaSavik — thank you for the detailed review. We have addressed all three items:

1. ✅ JSON formatting — PR Add MYRX-MAINNET (Chain ID 8472) #232 is scoped strictly to Chain ID 8472, +16 lines, zero reformatting of other entries.

2. ✅ Full-featured explorer — explorer.myrxwallet.io is now running Blockscout v6.10.0 (deployed 2026-05-14). Full transaction search, address lookup, contract verification interface, real-time block feed.

3. ✅ Blockscout attribution — "Powered by Blockscout" footer with link is live on the explorer page.

The clean resubmission is at #232. Would appreciate a re-review when you have a moment. Thank you.
