Frequently asked questions

Is it safe to add Quartz by Unique to MetaMask?▾
Yes, if you use the "Add to wallet" button on this page. Data is sourced from chainid.network — the community-audited Ethereum registry. Adding a network does not expose your private key or grant any permissions to the dApp.
What is Quartz by Unique Chain ID?▾
The Chain ID of Quartz by Unique is 8881. This unique number identifies the network and prevents MetaMask and other EVM wallets from mixing up transactions across different chains.
Do I need QTZ tokens to use Quartz by Unique?▾
Yes. Every transaction on Quartz by Unique requires QTZ to pay gas fees. You can purchase QTZ on exchanges and bridge it to Quartz by Unique, or use a faucet if this is a testnet.
What is the Quartz by Unique RPC endpoint?▾
An RPC endpoint is the server address your wallet uses to communicate with the Quartz by Unique blockchain — sending transactions, reading balances, and checking state. One popular Quartz by Unique RPC is https://rpc-quartz.unique.network. This page shows live latency for each RPC so you can pick the fastest one.
My wallet says Quartz by Unique already exists when I click Add — what do I do?▾
That's completely normal. If Quartz by Unique is already in your wallet, it will simply switch to that network instead of adding a duplicate — no error or conflict.
I added Quartz by Unique but the network won't load — what's wrong?▾
The most common cause is a broken or overloaded RPC endpoint. Your wallet uses RPC to connect to the blockchain — if the RPC is down, the network won't load even if it was added correctly. Fix: copy a different RPC from the list above (prefer green low-latency ones), then go to Settings → Networks in your wallet and replace the old RPC with the new one. Watch the tutorial video above for step-by-step instructions on updating your RPC.
