Subject: [PATCH] docs: align Networks section + add MetaMask guide
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Mainnet name was "Sentrix Mainnet" — every official source (frontend
chain configs, genesis, chainlist submission) actually uses "Sentrix
Chain". Updated. Networks section also gains the RPC URLs (previously
only chain ID and explorer were listed) so users can copy-paste into
MetaMask without a second hop.

Adds the MetaMask setup guide that issue #1 asked for, with values
matching the chainlist submission. Testnet block explorer points at
scan-testnet.sentrixchain.com (the dedicated testnet host) so EIP-3091
deeplinks route correctly. Drops the now-completed "Add Sentrix to
MetaMask" line from the recommended-topics list.

Supersedes #3 — same intent, corrected values.

+### Add Sentrix to MetaMask
+
+Sentrix Chain is EVM-compatible, so mainnet and testnet both add as custom networks in MetaMask. Open **Settings → Networks → Add a network → Add a network manually** and use the values below.
+
+#### Sentrix Chain (mainnet)
+
+| Field | Value |
+| --- | --- |
+| Network name | `Sentrix Chain` |
+| New RPC URL | `https://rpc.sentrixchain.com` |
+| Chain ID | `7119` |
+| Currency symbol | `SRX` |
+| Block explorer URL | `https://scan.sentrixchain.com` |
+
+#### Sentrix Testnet
+
+| Field | Value |
+| --- | --- |
+| Network name | `Sentrix Testnet` |
+| New RPC URL | `https://testnet-rpc.sentrixchain.com` |
+| Chain ID | `7120` |
+| Currency symbol | `SRX` |
+| Block explorer URL | `https://scan-testnet.sentrixchain.com` |
+| Faucet | `https://faucet.sentrixchain.com` |
+
+Use the [Sentrix Faucet](https://faucet.sentrixchain.com) to request testnet SRX after adding Sentrix Testnet.
