How to connect to GIWA testnet: RPC, chain ID, faucet, first transaction
The GIWA Sepolia testnet — the public test network of Upbit operator Dunamu's Ethereum L2 — is open to anyone with an EVM wallet. Setup takes about one minute and everything after it is free. These are the exact parameters, the working faucets, and a first-hour itinerary that leaves real transactions behind.
Step 1 — add the network
In MetaMask (or any EVM wallet): Settings → Networks → Add network → Add manually, then enter:
| Network name | GIWA Sepolia |
|---|---|
| RPC URL | https://sepolia-rpc.giwa.io |
| Chain ID | 91342 |
| Currency symbol | ETH |
| Block explorer | https://sepolia-explorer.giwa.io |
Shortcut: connecting a wallet on giwa.markets offers to add the network automatically — one click instead of five fields.
Step 2 — get testnet ETH
- Official faucet: faucet.giwa.io
- Backup faucet (Nodit): faucet.lambda256.io/giwa-sepolia
0.01 ETH is plenty — blocks come every second and fees are fractions of a cent in testnet terms. It covers dozens of transactions including a full token launch. Testnet ETH has no monetary value; never pay anyone for it.
Step 3 — do the official things
The GIWA Playground at giwa.io carries the official quests: bridge, register your free soul-bound giwa.id name, and collect Dojang attestation stamps for completed tasks. These are the chain's own participation records — the reasons to care are covered in the airdrop positioning guide.
Step 4 — do the fun things
A testnet is only as interesting as its apps. On GIWA.MARKETS, all of these are live and each one is a real on-chain transaction:
- Launch a token in ninety seconds — pick a mode, name it, seed the curve. The launchpad guide walks every step.
- Trade the board — bonding-curve buys and sells on live launches.
- Mint on-chain art — TILES 瓦 and GONGSIN 功臣, SVG drawn by the contracts themselves, no IPFS.
- Play GIWA QUEST — the browser MMO where your GONGSIN is your character. Free at giwa.markets/play.
