How it works

• Your wallet. Created on your phone the first time you open xchange, protected by a 6-digit PIN, backed up encrypted in your Telegram cloud. Only you hold the keys.
• Place an offer. Choose what to sell and your price. Your funds move into an escrow contract on their chain, signed by you.
• Get matched. xchange matches offers by price and time, like an exchange, off chain.
• Settle. When both sides are in escrow, the contracts release each side to the other. On Solana this takes seconds; a Gaju leg waits for confirmations, up to about eight minutes.
• Cancel any time. An unmatched offer refunds to you with one tap and your PIN. An expired one refunds on its own.
• What xchange cannot do. The escrow contracts release only to the counterparty of your trade or back to you. xchange cannot send your funds anywhere else.
