memecoins, with leverage.

The whole mechanism on one page: what a position costs, what it locks up, when it closes on its own, and what nobody here is able to do with your money.

leverage: 1–20x; chosen per position, long or short
fee: 0.1%; of notional, on open and on close
maintenance: 2.5%; of notional must remain as margin

Omen lets you take a leveraged long or short on any memecoin trading on Solana. You sign in with an email or a Solana wallet, we make a wallet for you on the chain, you fund it with SOL, and from then on every coin's page has a chart and a panel where you pick a side, a size and a leverage.

Spot memecoin trading gives you one direction and one speed. Here you get both directions, and up to 20 times the speed.

Prices come from the coin's own pool on Solana, read through GeckoTerminal and DexScreener. Positions are kept on your account, marked to the live price, and closed automatically if the price reaches the level where your margin would be gone.

your account and wallet

Signing in creates two things: an account, identified by your email or by the Solana address you signed with, and a custodial wallet on Solana that belongs to that account. The wallet's key is generated on our server and is never shown in the browser.

Your wallet: One Solana address, shown in the header and on the Portfolio page. Send SOL to it to fund your account. It is yours for as long as the account exists.
Collateral: The SOL in your wallet, valued in USD at the live SOL price, plus or minus the result of your closed trades. Free collateral is what is not locked as margin in open positions.
Sign-in methods: Email and password, or a Solana wallet in your browser such as Phantom or Solflare (you sign a message, never a transaction). Both give the same kind of account and wallet.
Not a seed phrase: There is nothing to write down. If you lose your password, recovery goes through your email; the wallet stays attached to the account.

the rules at a glance

Direction: Long profits when the price rises; short profits when it falls. Both are available on every listed coin.
Leverage: Any whole number from 1x to 20x, chosen when you open. It cannot be changed on an open position.
Size: You choose the position's notional in USD, from $5 to $250,000. Margin locked is notional divided by leverage.
Fee: 0.1% of notional when you open and again when you close. Nothing else: no funding, no spread of our own.
Liquidation: When the price moves against you far enough that only 2.5% of notional remains of your margin, the position is closed at that price. Details
Maximum loss: Your margin, never more. A liquidated position costs exactly the margin you posted. Your other positions and your free collateral are untouched.
Closing: One click, at the live price. Profit or loss is settled to your collateral the same moment.
Listed coins: Every memecoin on Solana with at least $10,000 of pool liquidity. Search finds the rest; the list shows what is moving. Details

from sign-in to a position

Sign in. Email or a Solana wallet. Your wallet is made in the same second and shown in the header.
Fund it. Send SOL to your wallet address. The balance appears in the header once the transfer confirms, usually within a second, and counts as collateral at the live SOL price.
Pick a coin. The Markets page lists what is trending, biggest and newest; search takes a name, ticker or contract address. Every row opens a page with the chart already loaded.
Open. Choose long or short, a leverage and a size. The panel shows the margin it locks, the fee, and the liquidation price before you confirm. The position opens at the live price and appears under the chart and on Portfolio.

leverage and margin

A position has a notional, the USD value of the coins it controls, and a margin, the part of your collateral it locks. Leverage is the ratio between the two. The profit or loss moves with the notional, so at 10x a $1,000 position gains or loses as much as $1,000 of the coin would, while only $100 of your collateral is at stake.

A 10x position	Amount
notional	$1,000
margin locked	$100
open fee (0.1%)	$1
free collateral needed	$101
a 1% move in the coin	±$10, which is 10% of your margin

Higher leverage does not change what you can win per dollar of notional. It changes how little you put down, and therefore how small a move takes all of it.

liquidation

Every position has one price at which it is closed for you. It is shown in the panel before you open, on the position row after, and as a line on the chart. The rule: the position is liquidated when your loss has eaten the margin down to 2.5% of notional.

Side	Liquidation price	At 10x, entry 0.0025
long	`entry × (1 − 1/lev + 0.025)`	0.0023125 · a 7.5% drop
short	`entry × (1 + 1/lev − 0.025)`	0.0026875 · a 7.5% rise

What it costs: Your margin, exactly. No close fee is charged on a liquidation, and nothing beyond the margin is ever taken.
When it happens: Positions are checked against the live price every time your account is read, which the app does every few seconds while it is open, and whenever you open or close. Memecoins move fast: a wick through the level counts.
At 20x: The gap to liquidation is 2.5%. On a memecoin that is often a single candle.

fees

One fee, 0.1% of notional, charged when a position opens and again when it closes. It is shown in the panel before you confirm, and it is taken from your collateral, not from the margin. There are no funding payments and no fee on deposits; Solana's own transaction fee applies to sending SOL into your wallet.

The fee is on notional, so leverage multiplies it. A $1,000 position costs $1 to open whether it is 1x or 10x.

prices and fills

Mark price: The coin's price in its deepest pool on Solana, read from DexScreener every couple of seconds. The same number drives the chart's last candle, your PnL and the liquidation check.
Fills: A position opens or closes at the mark price at that moment. There is no slippage model and no order book: you get the price the panel shows, within the second or two it takes to confirm.
Candles: From GeckoTerminal, in 1-minute to 4-hour bars. If their feed is throttled, the last known candles are shown and marked as stale rather than an empty chart.
Market cap axis: The chart can show market cap instead of price, the way memecoin terminals do. It is the same candles scaled by supply.

which coins are listed

Anything with a pool on Solana shows up in search. The Markets page ranks them three ways: Trending by activity inside a window you pick, boosted for fresh pools; Top by volume today, weighted toward the last hour; New by pool age. Majors and stablecoins are left out.

A coin can be opened only while its pool holds at least $10,000. Below that a single trade moves the price so much that a mark price stops meaning anything. Existing positions on a coin that falls under the line can still be closed.

who controls what

You: Open and close positions, choose leverage and size, send SOL in. Your wallet address never changes.
Us: Hold the key to your wallet, which is how trades are placed and funds moved without you signing anything. Set the risk parameters on this page: leverage band, fee, maintenance margin, liquidity floor.
Not us: Change a position after it is open, alter your entry or liquidation price, or move your SOL anywhere but where the app's own flows send it. Every parameter on this page is read from the same constants the engine runs on, so what you read here is what runs.

limits and risks

Custodial: We hold the key to your wallet. That is what makes one-click trading possible and it is also the risk: if our systems were compromised, so could the wallets be. Keep what you trade with, not what you keep.
Memecoins: These coins can lose most of their value in minutes, and some pools are thin enough that one trade moves the price. Leverage turns that into liquidation. Assume any position can go to zero.
Data sources: Prices depend on GeckoTerminal and DexScreener. If both stop answering for a coin, no positions on it can be opened or closed until one returns, and liquidation checks pause with them.
Not an exchange: Positions are held on your account, not on an order book with other traders. The counterparty to your position is Omen.
Unaudited: The engine and the wallet flow have not been audited.
