The pitch, ready

A group savings goal in BTC that stakes on Starknet while you save.

Problem: Friends saving together in a paluwagan or group chat lose track of who paid, and early withdrawals become awkward conversations that end friendships.

Solution: A shared BTC pot on Starknet with weekly deposits, a visible streak, optional staking while it waits, and a group threshold for any early withdrawal.

Why now: BTC liquid staking routes on Starknet and cheap batched deposits make a small group pot practical, and Filipino friends abroad already save together.

Market: Barkadas, families and OFW communities saving for trips, weddings and emergencies.

The ask: Pilot partners: two OFW associations and one peso on-ramp, plus Starknet ecosystem programs.

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

BLUEPRINT

Why it matters and how it really works

The need

Friends who save together for a trip or a shared goal usually keep the pot in one person's account. It gets borrowed, spent or forgotten, and friends abroad cannot easily chip in. Nobody wants to be the one chasing deposits.

What exists and what is new

Liquid BTC staking already exists on Starknet (for example Endur), and rotating savings circles (paluwagan, susu, tandas) are old and common, mostly off chain. Our research did not find a group BTC savings goal on Starknet that stakes the pot while it waits and requires group approval for early withdrawals. The parts exist; the group goal wrapper is the new piece. Research verdict: medium novelty.

The data it runs on

Circle members' wallet addresses, the goal, deposit schedule and approval threshold, each deposit and approval transaction, and the staked position. Names, peso amounts, reasons for early asks and chat stay in the app database, private to the circle.

1.The mission

Help small groups of friends save for the things they keep promising each other, with a pot nobody can quietly empty.

2.Why people can't resist it

The postcard fills up A drawn postcard of your destination fills as the pot grows, shown in BTC and in your currency.

Friday streaks A shared streak for weeks when all members deposited. Nobody wants to be the one who breaks it.

The rule does the talking Early asks go to the group. No awkward chats about who took money out.

3.How it works for real

Circle contract: A Cairo contract on Starknet holds the pot, records each member's deposits and releases funds only at the goal date or with the approval threshold met.

Accounts: Starknet smart accounts (for example Argent or Braavos style, or an embedded wallet SDK) so friends abroad can join with email sign in and no seed phrase.

Staking route: Optional deposit of the pot into a liquid BTC staking protocol on Starknet such as Endur. Yield is variable. Unstaking has a wait, so the contract starts it 10 days before the goal date.

On and off ramps: Members buy BTC (wrapped on Starknet) through a fiat ramp provider in their country, or bridge it in. The app never holds fiat.

Circle agent: A small model (for example Claude Haiku tier via OpenRouter) writes payday nudges in each member's time zone and summarises early asks. It cannot move funds.

Indexer and notifications: An indexer over circle events drives the shared page, streaks, push and Telegram or WhatsApp style notifications.

4.Cost per use and pricing

Per deposit on Starknet: usually a fraction of a US cent in fees at recent rates, plus any staking protocol fee. Batching Friday deposits keeps it lower. Agent nudges on a small model cost well under 1 US cent per member per week. Example: 1,000 circles of 5 members cost roughly 100 to 200 US dollars a month in hosting, indexing and model calls.

Barkada Free

One circle, up to 5 members, one goal.

Plus $2 a month per circle

Up to 12 members, custom goals and postcards, streak history and export.

Organiser 0.5% at goal

For clubs, churches and teams running many circles, with admin tools. Charged only when a goal is reached.

5.Growth loop

Every circle invites 4 or more friends to sign up. Share cards when a goal is reached travel through group chats, and finished circles start the next trip.

6.Risks and guardrails

Price risk: BTC price can fall while saving, so the trip may cost more in local currency. The app shows both numbers and promises neither.

Staking risk: Liquid staking adds smart contract and depeg risk, and yield can be zero. Staking is off by default and clearly labelled.

Legal: Group savings and crypto rules vary by country, and running pooled funds may need licences in some places. The owner must check local rules.

Collusion: A majority could approve releasing funds to themselves. Releases are limited to the asker's own deposits unless everyone agrees.

Lost access: Members can lose their accounts. Social recovery through the circle is supported, with a delay.
