How to use the Sentrix Faucet
The faucet hands out small amounts of SRX so you can interact with Sentrix Chain without paying for gas first. There are two modes — one for builders, one for end-users — with different drips and different protections.
Two faucets, one site
Testnet
chain 7120
Builders, CI, integration tests
- Drip
- 10 SRX
- Cooldown
- 24 hours per IP + per address
- Captcha
- None
Tokens have no real value. Use freely for development.
Mainnet
chain 7119
New users who just made a wallet
- Drip
- Tiny (gas-only)
- Cooldown
- One claim per address, ever
- Captcha
- Required (Cloudflare Turnstile)
Real SRX. Sized to cover a few transactions, not to fund a wallet.
How to claim
- 01
Have a wallet
Any EVM-compatible wallet works (MetaMask, Rabby, Frame, Sentrix Solux). You only need the address — no signature, no connect.
- 02
Pick the right faucet
Open faucet.sentriscloud.com. The header shows the current network. Make sure it matches the chain you actually want to use.
- 03
Paste your address
Paste the full 0x… address (40 hex characters). The page validates the format before submitting.
- 04
Solve the captcha (mainnet only)
On the mainnet leg, complete the Cloudflare Turnstile challenge. It's privacy-friendly and usually clears in a second without interaction.
- 05
Click request
The site signs the transaction server-side and broadcasts to a Sentrix node. Once confirmed, you'll see the transaction hash with a link to SentrixScan.
Rate limits
Limits are enforced server-side by both IP address and wallet address. The stricter of the two wins:
- ·Testnet: 1 claim per IP per 24h, 1 claim per address per 24h.
- ·Mainnet: 1 claim per address ever (lifetime). IP rate limit on top to slow automated harvesting.
- ·The browser also stores a last_claim timestamp in localStorage so you see a live cooldown countdown — but the server is the source of truth.
Why mainnet has a captcha
Mainnet drips are real value. Without friction, a single attacker running a sybil farm could drain the faucet wallet across thousands of fresh addresses in minutes. Cloudflare Turnstile adds a passive challenge that's invisible to most humans but rejects most automated traffic.
Testnet has no captcha because the tokens are worthless and devs need scriptable access for CI.
Network details
| Field | Mainnet | Testnet |
|---|---|---|
| Chain ID | 7119 | 7120 |
| Native token | SRX | SRX (test) |
| EVM | revm 37 | revm 37 |
| Faucet drip | Gas-only | 10 SRX |
| Captcha | Required | None |
| Cooldown | 1 / address (lifetime) | 1 / address / 24h |
Troubleshooting
- Invalid wallet address
- The faucet expects exactly 0x followed by 40 hex characters (0-9, a-f). No checksum required — upper or lower case both work.
- Rate limit error even though I never claimed
- Your IP may be shared (mobile network, VPN, NAT). Try from a different network. On mainnet, an address that's already been used won't qualify regardless of IP.
- Captcha keeps failing
- Disable aggressive privacy extensions (uBlock filter lists, hard tracking-protection modes) and reload. Cloudflare Turnstile is privacy-friendly but some custom blocklists still flag it.
- "Sentrix node unreachable"
- The faucet talks to a Sentrix node over JSON-RPC. If the node is syncing, restarting, or under load, you may see this transiently — wait ~30 seconds and retry.
- Transaction sent but balance hasn't appeared
- Click the transaction link to SentrixScan and confirm it was included. Wallets vary in how aggressively they refresh balances — some need a manual reload.
