Rumpel.
The night shift for your bags.
Coins on Robinhood Chain die at night, while their holders sleep. Rumpel watches yours, tells you the truth about each coin and the people trading it, and gets you out on time.
Rumpel is not live yet. Pages run on example data until the server goes live.
In short
- What it does: watches the coins in your wallet through the night and prepares the exit when a rule you set trips.
- What it never does: hold your coins or keys, or move anything without your signature.
- What it reads: who launched a coin, who is leaving it, and how much of your bag can still get out.
- What runs today: every page on example data; the departures board on live Lighter trades. Live
- What is planned: live bags and quotes, Telegram alerts, $STRAW, then an audited keeper. Planned
Why we made it
On a broker app every position can carry a stop-loss and a take-profit. On Robinhood Chain there is no such button: you buy a coin and then you watch it yourself, day and night. Most memecoins on the chain die within days; the dev sells, the pool thins out, the top holders leave, and by morning the coin is straw.
The tools that watch for you today are trading bots that hold your keys, or scripts on someone's laptop. We wanted the opposite: something that watches your own wallet, tells you plainly what it sees, and moves nothing without your signature.
The night crew
The little man has helpers, one for each part of the product.
How the night shift works
- WatchConnect a wallet or paste any address. Looking signs nothing.
- WarnA rule you set trips; the server checks every rule around the clock.
- Prepare exitA fresh route, tried in a simulation first, against the price you would really get.
- You signIn the app or from Telegram. One signature sends it.
- DoneThe coins you chose leave as ETH, USDG or gold.
Rules are checked against the exit you would really get: a live quote for selling your actual bag, slippage included, not the chart price. Free covers exits on three coins. Holding $STRAW lifts the limit. Planned
Six kinds of exit, each with how much to sell and what you get back:
- It falls by a share, from now or from its peak
- It rises to a multiple
- The dev sells part of their bag
- Its Straw Score passes a line
- Its way out narrows below a share
- Some of the best traders holding it start selling
Straw Score
The chance a coin dies in the next 24 hours, from 0 to 100, with the reasons in plain words. Higher is worse. It weighs what the chain shows:
| Factor | What it reads |
|---|---|
| Dev history | How the dev's earlier coins ended and what they took out |
| Snipers | How much of the supply went in the first blocks |
| Linked wallets | Supply held by wallets funded from one source |
| Concentration | What the ten biggest holders own |
| Washed volume | Trading that real buyers do not explain |
| Exit depth | How much a sell of $1,000 loses to slippage |
| Launch curve | Still on it, or graduated to a pool |
Today the score is a weighted sum of these factors, and every factor is shown with its weight. A model trained on launches whose ending we know will set the weights. Planned
Way Out
A rug takes you on the way out: the pool gets too thin for your bag, and selling it all would lose most of it. Way Out asks for real quotes to sell different parts of your bag and finds the largest share that still sells for under 5% slippage. It shows that share, how it moved over the last two hours and where it is heading, and wakes you before it drops under your line.
When the door narrows, Rumpel prepares "leave with what can leave": the part that sells cleanly now in one signature, the rest in slices as the pool refills.
The Hall and Rumpel Score
Ordinary leaderboards show who made money. The Hall ranks traders by how they leave. Rumpel Score runs from 0 to 10 over closed trades in a period; higher is better.
- 40% Peak takenhow much of a coin's top after their entry they kept
- 30% Out before a crashexits made before a fall of more than half
- 20% Profitover the period
- 10% Shallow drawdownhow deep they let a position sink
Each profile shows profit day by day, every exit against the coin's peak, what they hold now, when they trade, style tags with the rule behind each, and wallets that look like the same operator. "Follow their exits" adds one rule to your night: sell a coin when some of the best traders holding it start selling. Rumpel copies exits, never entries.
Clean up
Every wallet fills up with dead coins nobody sells one by one. Clean up finds them all, tries each sell before promising anything, and spins the ones worth more than their gas in one go into ETH, USDG or gold. Coins that can never be sold are named as such and can be burned to tidy the wallet.
You sign every exit
Rumpel never holds your coins or your keys. Signing in proves the wallet is yours with a message that cannot move anything. Every exit is a transaction your own wallet shows you before you sign it: what you sell, what you get at least, and the fee. Where the wallet supports it, the approval and the sell go in one signature.
Fees and $STRAW
Fees are taken from what you receive, through the swap route itself, and shown before you sign.
| Free | With $STRAW | Status | |
|---|---|---|---|
| Fee on an executed exit | 0.5% | 0.25% | Planned |
| Fee on Clean up | 1% | 0.5% | Planned |
| Coins with exits | 3 | Unlimited | Planned |
| Rules checked every | 1 min | 20 s | Planned |
| Way Out measured every | 5 min | 1 min | Planned |
$STRAW is not launched. Holders also get a wider Hall to follow. The token gives more room and a lower fee, never a different truth.
Where the data comes from
Your browser talks only to Rumpel's own server; the server talks to everything else from its own address, so third parties never see yours.
| Source | What for |
|---|---|
| Robinhood Chain RPC | Balances, contracts, sell simulations |
| Blockscout | Tokens in a wallet, transfers, holders, who created a coin |
| 0x, KyberSwap | Routes and quotes for exits, Way Out and Clean up |
| Bitquery | Trades and launches on Pons, Pools.trade and Uniswap, for the Hall, Straw Score and the launch radar |

Risks and limits
One-block collapses
An exit is only as good as the market at that moment. If a coin collapses in one block, no watcher is fast enough.
Sleeping through the alert
Phase one needs your signature: if you sleep through the alert, the exit waits. A keeper that sells without waking you, capped by your own floor, comes only after an independent audit. Planned
Coins on a launch curve
Coins still on a launch curve may have no route out; Rumpel says so instead of pretending.
Stock tokens
Stock tokens trade 24/5 and are not offered in some countries, including the United States. Their exits fill only while their market is open.

Questions
Do you hold my coins?
No. They stay in your wallet, and every exit is signed by you.
What if I sleep through the alert?
The exit stays ready and is routed again when you open it. Until the audited keeper exists, nothing sells without you.
Can I check a coin without connecting?
Yes. Check, Wallet X-ray and the Hall work with any address or ticker.
Who is behind the numbers?
Public chain data and the services listed above. Every score shows what it weighed.
