Who it is for

Tolu trades perps; her cousin keeps a reserve in Margin Buddy. When Tolu's position gets within five percent of liquidation, the reserve adds margin and Tolu owes a small fee back.

What exists today, and what this does differently

What is new

Auto top up bots exist privately; a peer backed, rule based margin guard was not found.

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 you own

The whole app, not a starter kit.

The pitch, ready

A friend backed guard that tops up your margin by rule when liquidation gets close, for a fee you agreed.

Problem: Perp traders get liquidated in short wicks while they sleep, often minutes before price comes back. Friends who would lend a few hundred dollars of USDC are never awake at the right moment, and an open ended promise puts their money at unclear risk.

Solution: Trader and backer sign one rule set: trigger distance, top up size, a nightly cap and a fee. A keeper reading the mark price adds margin from the backer's vault, which can only pay the trader's account, and a ledger tracks repayment.

Why now: Hyperliquid and HyperEVM make margin and vault transactions cost cents, embedded wallets remove the setup wall for non trading backers, and keepers can watch every block cheaply.

Market: Retail perp traders on Hyperliquid and the friends, family and small trading clubs who already informally back each other.

The ask: Hyperliquid ecosystem builder support and two trading clubs to pilot Desk reserves.

Your 2 minute demo

Home: Tolu at 01:47 in Lekki, Kemi's rope tied, the distance gauge and one next action.
Rope: change the trigger, see both signatures reset, sign as Tolu and watch Kemi sign.
Night: play the 1 AM wick, the rope adds $300 at 4.6% and both phones ping.
Ledger: repay Kemi with her fee and the app fee, open the onchain receipts.
Backers: try to add Bola, hit the Circle lock, pay with the USDC checkout, Bola fills second.
Owner Revenue: change the Circle price in the paywall editor and preview Plans in the user app.
Owner Rules: turn off mark price, run a night in Agent and see top ups rejected.
Owner Roadmap: request the v2 backer circles add-on.

BLUEPRINT

Why it matters and how it really works

The need

Perp traders get liquidated in short wicks while they sleep, often minutes before price comes back. Friends and family who would gladly lend a few hundred dollars of USDC are never awake at the right moment, and an open ended promise to help puts their money at unclear risk.

What exists and what is new

Automatic margin top up already exists as private keeper bots that traders run on their own funds, and lending markets on HyperEVM such as HyperLend let you borrow against collateral. What we did not find is a peer backed guard: a named backer's reserve, a rule set both people sign, a hard cap the backer sets, and a repayment plus agreed fee tracked in one ledger. Research verdict: medium novelty; the top up mechanic itself is not new.

The data it runs on

The trader's position (mark price, liquidation price, margin) read from Hyperliquid, the signed rule set (trigger distance, top up size, nightly cap, fee, repayment window), the backer's vault balance, and every top up and repayment transaction. Chats, phone numbers and the trader's strategy stay offchain.

1.The mission

Let the people who already trust each other catch each other in a wick, with rules both sides can read and a cap the backer controls.

2.Why people can't resist it

A rope with a visible length The backer sees the cap before signing and never more than the cap can move in a night.

Both phones ping When the rule fires, the trader learns margin was added and the backer learns exactly what is owed and by when.

The Sunday rope check A ten minute weekly review together: is the reserve right, has the position changed, keep the trigger. Repayment streaks show on both sides.

3.How it works for real

Wallets: Privy embedded wallets for trader and backer, with the backer's USDC held in a vault contract on HyperEVM that can only send to the trader's Hyperliquid account.

Signed rule set: Trigger distance (3, 5 or 8 percent), top up size, nightly cap, fee and a 5 day repayment window are signed by both and stored as a hash onchain.

Watcher: A keeper polls the position once a minute and every block once inside twice the trigger. It reads the mark price the exchange liquidates on, not last trade, and keeps a small buffer in the margin math.

Top up: When distance falls below the trigger, the vault sends the agreed size as margin, at most once per 30 minutes and never past the cap.

Repayment and fee: The trader repays each top up plus the agreed fee into the vault. A 0.5% app fee on top ups funds the keeper and gas.

Ledger and alerts: An indexer over vault events powers both dashboards, the receipts view and push or messaging alerts.

4.Cost per use and pricing

Most nights cost nothing beyond polling. Keeper hosting and RPC roughly $20 to $40 a month for a few hundred watched positions; each top up and repayment is a HyperEVM transaction costing cents. Example: a $300 top up at 2% fee returns $6 to the backer; the 0.5% app fee is $1.50, which covers the transactions with room for the keeper.

Pair 0.5% of each top up

One trader, one backer, one rule set. Nothing charged on nights the rope does nothing.

Circle $9 a month

Up to five backers per trader, per position rule sets, and the weekly review export.

Desk $49 a month

For small trading clubs: many traders, shared reserves with per member caps, and audit exports.

5.Growth loop

Every top up pings two people, and the backer often becomes a trader or backs a second friend. The share card shows a wick caught with the cap visible, which invites the exact conversation the app makes easy: would you be my backer.

6.Risks and guardrails

It cannot stop a loss: A top up buys time and puts more money in the trade. The app says so before signing, and the cap is the backer's limit on that risk.

Wrong price, failed top up: Reading the wrong price can make the exchange refuse margin. The watcher uses mark price, keeps a buffer, and retries within the same block window.

Repayment default: The trader may not repay. Repayment is a promise between people, not enforced credit; streaks are visible and the backer can pause the rule at any time.

Keeper downtime: If the watcher is offline the rope does nothing. Redundant keepers, health alerts to both people, and no claim of guaranteed coverage.

Regulation: Peer lending with fees can be regulated in some countries. Owners should check local rules; the app does not market fees as returns.

Why own Margin Buddy

Margin Buddy: A friend backed guard that tops up your margin by rule when liquidation gets close, for a fee you agreed. Using someone else's version means their rules, their brand and their revenue. Owning Margin Buddy means it is deployed under your wallet, carries your name, and every customer, partner and result builds your track record instead of theirs.

What’s stopping you?

“I am not technical.”

Margin Buddy arrives deployed with a guide. Running it is settings and sharing links, not code. If you get stuck, we help you ship it.

“What if nobody uses it?”

Start with ten people you already know. The first move below takes under an hour and tells you fast whether people care.

“I do not have time.”

Each step is sized in minutes. Most owners spend an hour a week, and the app does the repetitive part.

“Will it make me money?”

Nothing is guaranteed. The playbook gives you a clear path and honest numbers, and you decide how far to take it.

The million-dollar ladder

Charge the people who get the most value from Margin Buddy: a monthly plan for groups or teams, plus setup fees for anyone who wants it done for them.
