The Cellar Coston2 testnet
Coston2 tester build Test tokens only

The Cellar by FlareCat. Balances and KOBAN here have no cash value, no promised airdrop and no mainnet carry-over. Test deployments may be replaced.

Check the address: cellar-coston2.vercel.app. Our main site is flarecat.xyz. If your wallet flags this page as malicious, stop and report the exact URL and warning in Cat Chat. Keep wallet security alerts enabled.

  1. Open this page in your wallet's browser, or use a browser wallet extension. Connect and switch to Coston2 when prompted.
  2. Get C2FLR for gas and test FXRP from the official Coston2 faucet. Never send mainnet tokens here.
  3. Try a small XRP Boost purchase, mint fcUSD, deposit into the Den, claim KOBAN, then test the exits. The Den keeps the one-hour hold.

What to expect

Before you confirm

Guide buttons open a page or form. They do not send a transaction.

A withdrawal request has no cancellation and can settle in several chunks. Guards and shared budgets apply on this testnet too.

During this private test, page visits, technical error codes, action names and transaction outcomes are reported to help improve the app. Public Coston2 activity is monitored too. Reports exclude wallet addresses, form values and raw error messages.

How fcUSD works

Create fcUSD with FXRP, the XRP token on Flare. Exchange it back for $1 worth of FXRP per fcUSD before fees, while backing is at least 100%. Holding fcUSD alone earns no interest.

Below 100%, everyone receives the same fraction of their claim from the remaining reserve. Price pauses and shared limits still apply.
