Try it yourself.
No permission, no waitlist.
Connect any wallet, take ten test STTR from the faucet, and spend it on an asset on another chain — or go the other way and buy STTR with an asset you already hold. Everything below runs against the real contracts on Base Sepolia.
Works with MetaMask, Rabby, OKX, Coinbase Wallet, Brave and any other EIP-1193 wallet — and with WalletConnect, so a phone wallet can scan a QR code instead. Nothing here has value: it is a testnet.
The faucet.
Ten test STTR per wallet, once every 24 hours. You will also need a little Base Sepolia ETH for gas — any public faucet will do.

The 24-hour wait is recorded on chain against your wallet address, not in this browser. Clearing site data, switching to a different browser, using another device or connecting through a different wallet app all read the same record and get the same answer.
A per-address cooldown cannot stop one person using several addresses — addresses are free and testnet gas is free — so the faucet also has a daily limit across everybody. That is the number above, and it is what actually bounds a draining attempt.
Spend STTR,
get an asset on another chain.
Your STTR is sold into the Base pool and the proceeds are handed to a bridge for the chain you pick. The STTR never leaves Base — it stays in the pool, where it is liquidity. Nothing is minted and nothing is burned.

Buy STTR with an asset you already hold.
On mainnet this asset would have arrived from whichever chain you hold it on. Here you can mint yourself some demo asset first, then swap it into STTR on the same Base pool.

What is real here and what is not
Real: the STTR token, the faucet, the swap router, the intent escrow and the pools are the contracts from this repository, deployed and running on Base Sepolia. The swap maths, the slippage floor, the approval handling and the bridge allowlist all behave exactly as they would on mainnet.
Not real: the bridge is a stand-in that records a transfer and emits an event — it does not move anything to another chain, because Stater deliberately does not ship its own bridge. On mainnet that step is handed to an audited third-party bridge. The destination assets are demo ERC-20s with an open mint, which is why you can give yourself some.
