Installation

Get Subslot running in under a minute.

Subslot is a Chrome extension — a side panel plus a full-page terminal that rides on top of the trading sites you already use. There is nothing to sign up for and no token to buy. Keys are generated and encrypted locally, and every transaction is signed on your device. It stays non-custodial from the first click.

Install from the Chrome Web Store

  1. Visit the Subslot listing on the Chrome Web Store.
  2. Click Add to Chrome and confirm the permissions prompt.
  3. The Subslot icon appears in your extensions toolbar. Click it to open the side panel.
  4. The panel opens on the right side of your browser and shows the onboarding screen.
Tip: Pin the extension for quick access. Click the extensions puzzle icon in the toolbar, then click the pin next to Subslot.

Create a New Wallet

  1. On the onboarding screen, choose Create Wallet.
  2. Give the wallet a name (for example "Main", "Trading", or "Sniper").
  3. Set a password and confirm it. The password must be at least 4 characters and encrypts your keys locally.
  4. A fresh Solana keypair is generated in your browser. The private key is shown once — copy it and store it somewhere safe (a password manager or a paper backup).
  5. Confirm you have backed up the key to continue.
  6. The key is encrypted with AES-256-GCM, using a key derived from your password with PBKDF2, and stored in Chrome's local storage. It never leaves your device.
Warning: If you lose your private key and forget your password, the wallet cannot be recovered. There is no backend, no cloud backup, and no support team that can restore it. Back up your key the moment it is shown.

Import an Existing Wallet

  1. On the onboarding screen, choose Import Wallet.
  2. Paste your private key in either supported format:
    • Base58 string — the standard Solana private key format (for example, exported from Phantom).
    • JSON byte array — a 64-byte array like [174,23,56,...,201] (for example, from solana-keygen).
  3. Give the wallet a name and set a password.
  4. The key is validated (it must produce a valid Solana public key), encrypted, and stored locally.

Bulk Import from CSV

To bring in several wallets at once, open the wallets menu and choose Bulk Import (CSV).

  1. Paste one wallet per line. Each line can be a bare private key, name,privateKey, or the exported name,address,privateKey format.
  2. A header row is detected and skipped automatically.
  3. Every key is validated, encrypted, and stored. Invalid lines are skipped and reported in the result.

Export Wallets

Export All (CSV) in the wallets menu downloads a CSV of your wallet addresses(public keys only) — private keys are never included in that export. To export a single private key, use the export action on that wallet's row; you will need to enter your password to decrypt it.

After Installation

Once your wallet is ready, navigate to any supported terminal — Axiom, Terminal (Padre), pump.fun, gmgn.ai, Photon, fomo, or DexScreener — and open a token page. Subslot auto-detects the token and loads it in the side panel, and you are ready to trade.
