GUI tokens
GUI indexer connection
This wallet verifies token rules and proofs locally. With full blocks it also downloads each whole Bitcoin block, so the indexer cannot leave a transaction out. With remote indexer it trusts the indexer to serve every GUI transaction.
Publishing
With a relay, the relay pays the Bitcoin fees and the 888-sat GUI fee per message from its own coins and you pay it in g_sats in the same transaction: no input, key or change of this wallet is in the Bitcoin transaction. The relay sees your messages, the fee you pay and your IP address unless you use Tor. Deposits, BTC listings, purchases, bids, open mints, collection deploys and file uploads always use this wallet's BTC.
Receive GUI tokens
Viewing key

Regtest marketplace
Fixed BTC prices and full fills. The listing carries your signed offer on chain, so buyers can purchase while you are offline. Experimental settlement: a Bitcoin reorg can invalidate an overlay lock.
Sale anchors
Spare sale anchors: 0. Each listing uses one 1,000-sat anchor, which returns to you with the payment.
Open and completed orders
Listings priced in GUI tokens
Sell a whole note for a GUI token (g_sats by default) or an NFT. No BTC changes hands and no sale anchor is needed; the buyer pays with one note of exactly the price. A listing stays open up to 100 blocks; take an unsold one back with Cancel.
