TabMates : the roommate ledger on Monad

TabMates : shared expenses with real settlements onchain. Open a tab with roommates, log expenses that split equally, and the contract nets everyone's debts down to one edge per pair. Hit settle and MON moves wallet-to-wallet in the same tx, no IOUs, no reminders. Sign in with email, Google, or any wallet via Privy (embedded wallet auto-created). No backend, no DB, the UI reads straight from contract view functions. Contract never holds custody. Live on Monad mainnet, Sourcify-verified, security-reviewed (expense caps, checked debt math, CEI + reentrancy guard). Only works because Monad confirms in ~400ms for near-zero fees, every expense is a real tx. Stack: Solidity 0.8.28 + Foundry (17 tests) · React + wagmi/viem · Privy · GitHub Pages
