How simul
works.
Everything the engine does, in plain words: what it reads, how it decides, how it buys and sells, where your money sits.
Where the traders come from
Three leaderboards: fomo.family, Axiom and pump.fun. Simul reads each one and keeps the wallet behind each name. From then on it watches the wallet itself, on-chain, so a trader can't hide a trade by leaving the app. You can also paste any Solana wallet.
Watch
Every confirmed transaction of a followed wallet is read in full. A swap is a swap: token balance up and SOL down is a buy, the reverse is a sell. First buys are told apart from top-ups.
Filter
| Rule | What it does |
|---|---|
| Size per copy | A fixed SOL amount, or a percentage of their buy with a cap. |
| Market cap band | Only coins inside your min/max. Too small or too big is skipped. |
| Token age | Fresh launches only, or anything up to the age you set. |
| Liquidity floor | Skip coins too thin to sell out of. |
| Their minimum buy | Ignore their tiny test buys. |
| First buys only | Copy the entry, not every top-up. |
| Take-profit steps | Up to three: at each gain, sell a share of what's left. |
| Stop loss / trailing | A fixed floor, or a stop that follows the peak. |
| When they sell | Cautious (take your stake back), mirror, sell all, or ignore. |
Every skip is logged with its reason.
Copy
A buy at your size, quoted and routed through Jupiter (which covers pump.fun curves, PumpSwap, Raydium, Meteora and the rest), signed by your simul wallet, sent with a priority fee. Median delay from their confirmation to your fill is shown live on the home page.
Exits
Positions are priced every few seconds. Take-profits sell their share, the stop sells all. After the first take-profit the stop is raised to your entry. Their sells trigger the mode you chose.
Your keys
Signing in creates a trading wallet for you. Its key is encrypted at rest with a server secret and never leaves the server unencrypted, except to you: export it any time with a signature from your login wallet. Withdrawals need that signature too.
Paper mode
10 SOL of paper money, real prices, real latency, same rules. Switch to live with one toggle once your simul wallet holds SOL.
Fees
1% of each live copy, taken on the buy and swept hourly. 0.5% for $SIMUL holders. Paper is free. Network and Jupiter fees are what they are.
Risk
Memecoins can go to zero in a minute. Stops limit losses, they do not remove them: a token with no liquidity cannot be sold. Copy with money you can lose.
