Send GM & Deploy Contract on QMS Testnet

Yes. QMS Testnet runs on test QMS from the official faucet, which has no real value, so sending a GM or deploying a contract costs you nothing real.

The chain ID is 19480 and the public RPC URL is https://rpc.testnet.qms.finance. The gas token is QMS, and the block explorer is QMSScan at https://testnet.qmsscan.io.

Connect your wallet and use Add network to your wallet on this page. Your wallet asks you to approve the new network. To add it by hand, enter chain ID 19480, RPC URL https://rpc.testnet.qms.finance and currency symbol QMS.

Use the official QMS faucet at https://faucet.testnet.qms.finance. It sends 10 QMS per request, up to four requests in 24 hours. Request it to the same wallet you connect to PingGM.

QMS blocks come from proof-of-useful-work, so block times vary around a 10-second target. If a GM seems slow, look up your address on QMSScan or check the network status at https://status.testnet.qms.finance.

Yes. QMS says the testnet may be reset at any time and its state may not carry over to the next version, so your GM and deployment history on it could be wiped.

QMS runs the Osaka hard fork from genesis, so compile for prague or osaka. Blob transactions are rejected, PREVRANDAO returns 0, and the safe and finalized block tags return genesis for now. Set maxFeePerGas explicitly so transactions don't stall when the base fee rises.
