About Subslot

One side-panel, every Solana surface.

Subslot is a non-custodial Solana execution terminal that rides on top of the tools you already trade on. It ships as a Chrome extension that plugs into Axiom, Padre, pump.fun, gmgn.ai, Photon, fomo and DexScreener — auto-detecting the coin in your tab, firing your whole wallet fleet at once, and launching pump.fun coins in a single atomic Jito bundle. 90% fee cashback, for everyone.

Every terminal takes a cut. We give it back.

Most Solana terminals skim ~1% per swap — 2% on a round trip — and keep every cent. On high-frequency memecoin trading that is real money. Subslot routes the exact same trades through Jupiter at a flat 0.4%, with 90% of it back as cashback — a net 0.04% per trade. No token to hold, no tiers to grind, no friction.

Everything in one side panel

Not a wallet with a swap button bolted on — a full execution stack for people who trade for a living.

Automatic token detection

The contract you're viewing is pulled straight from the terminal in your tab — Axiom, Padre, pump.fun, gmgn.ai, Photon, fomo and DexScreener — via URL parsing and DOM scanning, ready to trade in one click. No copy-paste, no tab-hopping.

Fleet trading

Group up to 50 wallets. Buys split proportionally across balances, a single tap dumps every position at once, and the dev wallet is protected from any auto-sell — all from one panel with 1-6 group hotkeys.

Five execution engines

Every trade routes the way you choose: the direct pump path, Jupiter Beam (default), Metis, Jito bundles or Helius Sender — switch with one dropdown. Never a silent reroute; a pump-only trade that can't route fails loudly.

Atomic pump.fun launcherPRO

Create a real pump.fun coin and snipe your own launch from up to 5 wallets in a single Jito bundle — all in one block, or none. Vanity “…pump” address, USDC-paired and Mayhem modes.

Auto engine

A volume bot bound to a dedicated group, MEV volume in one atomic round trip (buy + sell in a single tx, near-zero price risk), and auto-sell the instant external SOL lands on your threshold — with TP/SL ladders and stop guards.

Real-time PnL

Exit-aware realized and unrealized P&L per position and per wallet, synced on-chain over WebSocket. Live “ext SOL in”, fees paid, and bag value stream into a position panel as trades land.

Everything unlocked, cashback for everyone

Every Pro feature — the launcher, USDC mode, the auto engine — is free for every user. Trades pay one flat 0.4% platform fee, and 90% of it comes straight back as cashback.

Your keys, your device, full stop

Local-first by design. Nothing custodial, nothing signed silently.

Non-custodial

Your keys never leave your device, and we never hold them.

AES-256-GCM at rest

Keys encrypted with a password-derived key (PBKDF2, 100k iterations).

Signed locally, always

Every transaction is signed on-device; private keys never touch the network.

Explicit approvals

Registered as a Wallet Standard wallet — every dApp signature opens a popup, nothing is signed silently.

Locked down

Auto-lock on idle and a strict Content Security Policy on the extension.

No data collection

No personal data. Optional anonymous analytics, off in one tap.
