Can You Get Free Sui Testnet Tokens?

Yes. Any developer or user can claim free Sui testnet tokens from faucet.sui.io with nothing more than a Sui address. There is no mainnet faucet, where SUI must be bought on an exchange, so the testnet faucet is the standard starting point for building and testing.

MetaMask does not work with Sui. The network sits outside the EVM, so MetaMask cannot hold test SUI or sign Sui transactions, and Ethereum developers will need a native wallet like Slush or Suiet instead, covered below. Our best crypto faucets guide ranks faucets across other chains.

How to Get Sui Testnet Tokens from the Official Faucet

The official faucet is the most reliable source, since it draws straight from the Sui Foundation's reserves rather than a third party. Once your wallet is ready, the whole process takes under a minute.

1. Open the faucet: Go to faucet.sui.io.
2. Add your address: Connect your Sui wallet, or paste your address into the field. You can copy your CLI address with sui client active-address.
3. Select Testnet: Use the network dropdown to choose Testnet. The same page also serves Devnet and Localnet, so double-check you are on the right one.
4. Pass the human check: Clear the verification prompt that screens out bots.
5. Request SUI: Click Request SUI and the tokens land in a few seconds. Refresh and request again for more, subject to the rate limit.

To confirm the tokens arrived, run sui client balance in the CLI, or look your address up on an explorer such as SuiScan or SuiVision. If nothing appears, check that your wallet is set to Testnet rather than mainnet.

Other Ways to Claim Test SUI

When the main faucet is rate-limiting you or its pool runs low, several backups fill the gap.

• Community faucets: The Sui docs list N1Stake and SuiLearn as community-run faucets, each with its own cadence such as one claim per day. Stakely also runs a Sui testnet faucet.
• Discord faucet: Join the official Sui Discord, open the #testnet-faucet channel, and post !faucet <your address>. Brand-new Discord accounts may sit in a short validation window before they can post.
• Command line and SDK: Developers can hit the faucet directly. A curl POST to https://faucet.testnet.sui.io/v2/gas requests gas for an address, and the TypeScript SDK exposes requestSuiFromFaucetV2 from @mysten/sui/faucet for the same job inside a script or test suite.
• Local network: For an effectively unlimited supply, spin up a local Sui network. Its built-in faucet hands out test SUI with no shared rate limit, which is the cleanest setup for heavy automated testing.

That last group matters more than it once did. Public faucets are increasingly drained by bots and automated agents within minutes of a refill, which is why providers now gate them behind human checks. For legitimate automated work, the SDK route and a local network are the intended paths, not scripting the public web faucet.

Setting Up a Sui Wallet for Testnet

Because Sui sits outside the EVM, the wallet step looks different from an Ethereum testnet. Slush, formerly Sui Wallet, is the official wallet from Mysten Labs and supports zkLogin, which creates a self-custodial wallet from a Google or Apple login with no seed phrase. Suiet is a popular open-source alternative aimed at developers.

After installing a wallet, switch its network to Testnet before you claim, or your balance will read empty. In Slush, open the network selector and choose Sui Testnet. Our explainer on why Sui cannot be added to MetaMask walks through the wallet choice in more detail, and our best crypto wallets guide compares the wider field.

What You Can Build and Test With Sui Testnet Tokens

Test SUI is the gas you spend rehearsing anything destined for mainnet. The testnet mirrors mainnet closely, so behaviour you see there usually carries across.

• Move smart contracts: Sui uses Move, a language first designed at Meta for safe asset handling, which removes whole categories of bugs such as reentrancy. Publish and upgrade packages, then call them with programmable transaction blocks.
• The Sui Stack: Walrus (decentralized storage), Seal (onchain access control), and Nautilus (verifiable offchain compute) all reached mainnet in 2025 and have testnet deployments. Test SUI lets you wire an app into storage, secrets, and offchain data before going live.
• DeFi and order books: DeepBook, Sui's native central limit order book, along with lending and DEX protocols, runs on testnet, so you can simulate swaps, liquidity, and trades without exposure.
• Real-world performance: Sui's Mysticeti consensus finalizes most transactions in under a second, so iterating on testnet feels close to production rather than the slow block times of older EVM testnets.

The agent angle shows up here too. Sui now ships pre-built skills for AI coding agents like Claude Code and Cursor, and test SUI is what both coding agents and autonomous on-chain agents spend while they build and rehearse flows.

Returning Unused Test SUI to the Faucet

Sui's faucet has a feature most chains lack: you can give tokens back. The pool is finite, and when it empties everyone's requests start failing, so returning what you do not need keeps the faucet working for the next developer.

Once your wallet is connected, the faucet page has a Return tokens to faucet button. If you would rather not connect, you can send unused testnet SUI to the return address published in the Sui docs. Returns apply to Testnet only, not Devnet or Localnet.

Final Thoughts

For almost everyone, the official faucet at faucet.sui.io is the right starting point, and a single drip stretches a long way because Sui gas costs a tiny fraction of a cent. Keep Slush or Suiet on Testnet, fall back to the Discord or community faucets if the pool is dry, and reach for the SDK or a local network once your testing turns automated.
