Paper trade Solana memecoins on GMGN and make PnL cards. Never touches your wallet. An open source VIBECODED paper trading tool to trade Solana memecoins on gmgn.ai and make PnL cards. SolSim never touches your wallet. It has no wallet permissions and no signing code. It reads prices and keeps a fake SOL balance on your computer. Features: Trade on GMGN with fake SOL: - A draggable, collapsible panel shows up on every Solana coin page on gmgn.ai - Start with 10 fake SOL (change it in Settings) and Reset any time. Old runs are saved, not deleted - Buy presets (0.1 to 20 SOL) or any custom amount - Sell by % (10/25/50/100 or custom), Sell Init to pull out your initial, and limit sells / stop-losses at a market cap you pick - Live position row: Invested, Sold, Remaining and PnL % Prices from GMGN itself: - Reads GMGN's own live price feed, so fills match the chart you're looking at, several updates a second - Falls back to Jupiter, then DexScreener, if GMGN's feed goes quiet. The panel badge shows Live, Backup price, or No price Realistic fills: - 1% platform fee and your priority fee on every trade - Price impact based on the coin's liquidity: big buys into thin coins fill worse, like real trading - Slippage works like GMGN: it's a max. A trade whose impact is bigger fails instead of filling PnL cards: - One click from any position, open or closed - Big PnL in USD or SOL, PNL / Sold / Hold / Bought, and a price line with your buy (B) and sell (S) points - Landscape or portrait, Neon Glow and Dark Overlay toggles - 6 built-in backgrounds or upload your own. Add your display name and avatar - Download PNG, copy to clipboard, or Share to X Safe by design: - No wallet connection, no private keys, no signing, no real trades - No remote code: everything runs from the folder you install - Only talks to gmgn.ai, Jupiter, DexScreener and GeckoTerminal - Your balance and trades stay in your browser Use: - Open any Solana coin on gmgn.ai. The SolSim panel appears. Drag it by its header. - Click the toolbar icon for positions, history, settings, Reset and Make card. - Limit sells only fire while that coin is open in a tab.
