How do I add Sentrix to MetaMask?
Open MetaMask → Settings → Networks → Add a network and fill in:
| Field | Mainnet | Testnet |
|---|---|---|
| Network Name | Sentrix Chain | Sentrix Testnet |
| RPC URL | https://rpc.sentrixchain.com/rpc | https://testnet-rpc.sentrixchain.com/rpc |
| Chain ID | 7119 | 7120 |
| Currency Symbol | SRX | SRX |
| Block Explorer | https://scan.sentrixchain.com | https://scan-testnet.sentrixchain.com |
Full walkthrough: MetaMask Network Config.
Where can I get test SRX (testnet faucet)?
Use the testnet faucet linked from the Developer Quickstart. Connect your wallet to testnet (Chain ID 7120) and request SRX — limits are per-address per day to prevent abuse.
What are the mainnet and testnet Chain IDs?
| Network | Chain ID |
|---|---|
| Mainnet | 7119 |
| Testnet | 7120 |
Always double-check the Chain ID in your wallet to make sure you're on the right network.
Where are the RPC, WebSocket, and REST endpoints?

Quick reference:
| Protocol | Mainnet | Testnet |
|---|---|---|
| JSON-RPC / REST | https://rpc.sentrixchain.com/rpc | https://testnet-rpc.sentrixchain.com/rpc |
| WebSocket | wss://rpc.sentrixchain.com/ws | wss://testnet-rpc.sentrixchain.com/ws |
How do I verify a smart contract?
After deploying, navigate to your contract on the Sentrix Explorer, go to the Contract tab, and click Verify & Publish. Provide the source code, compiler version, and optimisation settings you used during deployment.
See the full guide in Smart Contract Guide.
How fast is block time and finality?
| Block time | ~1–2 seconds |
| Finality | Instant — Voyager DPoS+BFT achieves supermajority finality within the same block |
Unlike probabilistic finality chains, once a Sentrix block is committed it cannot be reverted under normal network conditions. You don't need to wait for confirmations.
What is the total SRX supply and halving schedule?
- Max supply: 315 million SRX
- Premine: 20% of cap
- Halving: every 126 million blocks (~4 years), mirroring Bitcoin's schedule
