Why it is new

What exists today, and what this does differently

What is new

Bill split apps exist; instant per order onchain splits were not found.

Closest things out there

Checked with web searches in October 2026. A search is not proof that nothing similar exists, and the market moves fast, so we recheck before every build.

What it unlocks

What you own

The whole app, not a starter kit.

The complete Tab Split app: friends open one group tab, every order is split only among whoever tapped in to that round and settled on MegaETH before the drinks land, with a paywall, owner console and tab helper built in.

The money path, built in

How it earns for you

Splitting a tab is free for up to 8 friends. Crews that go out weekly pay a small monthly fee for standing tabs, recap history and carry over deposits, and bars pay monthly to plug in their POS and table QR codes.

FriendsFreeUp to 8 people per tab, manual orders

Crew$3 a monthStanding weekly tabs, recap history, carry over deposits

Venue$29 a month per barPOS integration, bar wallet payouts, table QR codes

A busy night of 20 splits on MegaETH is expected to cost well under $0.10 in gas. Bar tabs go straight to bar wallets, never through the owner.

Prices are yours to set. Illustrative, not a promise of income.

The pitch, ready

A group tab where each order is split among friends the instant it is placed.

Problem: Group nights end with one person fronting the whole bill and chasing the rest for days, and even splits make light drinkers pay for rounds they never joined.

Solution: Friends put down a small USDC deposit that is also their cap. Each order splits only among those who tap in, deduped by POS ticket, and unspent deposits return at close.

Why now: Embedded wallets make joining a tab a QR scan, and MegaETH settles a split in well under a second for fractions of a cent.

Market: Friend groups who go out weekly, and the bars that want faster, fairer group tabs.

The ask: A pilot with three Bushwick bars and their regular crews.

Funding is never guaranteed. Check each program's rules.

For hackathons and demo days

Your 2 minute demo

Home: meet Inês, who fronts every Friday tab.
Tab: six friends join with $40 deposits as caps.
Order: the pints split five ways because Kwame only drinks ginger beer.
Night: close out, deposits return, share the recap.
Friday: vote on next week's bar, hit the Crew paywall for a standing tab and pay in USDC.
Owner Agent: the vegan wings guess and the re rung ticket, both fixed.
Owner Revenue and Venues: change the Crew price, decline a bar that wants to charge everyone.
Owner Growth and Roadmap: run a takeover night, then request the venue toolkit.

Many hackathons require code written at the event. See the Regatta Boardfor each race's rule.

BLUEPRINT

Why it matters and how it really works

The need

Group nights out end with one person fronting the whole bill and chasing the rest for days, and even splits make light drinkers pay for rounds they never joined.

What exists and what is new

Bill splitting is well served: Splitwise tracks who owes what after the fact, and payment apps settle IOUs later. What we did not find is a tab where each individual order is split among only the people who joined it and settled onchain the moment it is rung in. The split math is not new; the per order, instant settlement on a realtime chain is the new part.

The data it runs on

Tab membership (wallets and nicknames), each member's deposit and spend cap, POS ticket ids and amounts, who tapped into each order, split transactions and the close out refunds. Item names stay on the bar's POS and in the app.

1.The mission

Nobody should have to front the night or do maths at 2 AM to be fair to their friends.

2.Why people can't resist it

Pay only for your rounds Tap into the rounds you want. The ginger beer drinker stops subsidising mezcal.

Settled before it arrives Each share is paid as the order is rung, so there is nothing to chase at close.

Friday crew A standing tab for the same group, a weekly vote on the bar and a streak with zero open IOUs.

3.How it works for real

Join the tab: Friends scan the tab QR and get a Privy embedded wallet. Each puts in a small USDC deposit that is also their spend cap.

Order comes in: The bartender rings the order on the POS, or a friend adds it in the app. The ticket id and amount reach the tab contract.

Who joined: A helper suggests who is in from the order; each friend must tap in within 20 seconds. Silence means not in.

Instant split: The tab contract on MegaETH pays the bar wallet from the joiners' deposits in one transaction, deduped by ticket id.

Close out: At close, unspent deposits return to each wallet automatically. A recap goes to the group.

4.Cost per use and pricing

Network fees on MegaETH are expected to be fractions of a cent per split; a busy night of 20 orders should cost the group well under $0.10 in gas. The helper uses a small model only to suggest joiners, roughly $0.001 per order. Check current MegaETH fees before launch.

Friends Free

Up to 8 people per tab, manual orders.

Crew $3 a month

Standing weekly tabs, recap history, carry over deposits.

Venue $29 a month per bar

POS integration, bar wallet payouts, table QR codes.

5.Growth loop

Every tab brings five or six new people into the app at once. Bars that accept it put the QR on tables, and each recap shared to a group chat invites the next crew.

6.Risks and guardrails

Bar acceptance: The bar must accept USDC or use an offramp. Without it the tab pays one member who pays by card, which weakens the promise.

Wrong joiners: Suggestions are never charged without a tap. Any share can be disputed until close.

Double charges: Each POS ticket id can split once; re rings are rejected.

Overspending: Deposits are hard caps. Top ups require the member's own tap.

Later
Any shared spend, from road trips to house shares, splits per purchase the moment it happens.

Why own Tab Split

Tab Split: A group tab where each order is split among friends the instant it is placed. Using someone else's version means their rules, their brand and their revenue. Owning Tab Split means it is deployed under your wallet, carries your name, and every customer, partner and result builds your track record instead of theirs.
