Which wallets work?
Ready and Braavos on Starknet mainnet. On mobile, use your wallet's dapp browser. Telegram's browser may not detect an installed wallet.
What are the fees?
No Cairn trading fee. AVNU and network fees apply and appear in the review. Your wallet shows the final network fee.
What if a trade is pending?
Open Activity and refresh its status. If a wallet response is unknown, check your wallet before trying again. Reverted transactions can still cost network fees.
