SplitStellar

SplitStellar is a group expense splitting app with Stellar payment links, wallet contacts, and settlement receipts.

It uses a familiar consumer app model: groups, shared bills, balances, who owes who, activity, and payment reminders. The Stellar edge is that every settlement can generate a web+stellar:pay link with destination wallet, amount, asset, and memo, so friends can settle from compatible wallets without the app holding funds.

This is not KYC, escrow, enterprise compliance, insurance, or a CLI. It is a standard consumer expense app with Stellar-native settlement.

Why This Fits Stellar Wave

• Familiar category: Splitwise-style group expense tracking.

• Contributor surface: split engine, settlement links, search, contacts, groups, receipt matching, mobile UI, SEP-10 wallet login, Soroban receipt attestations.
