Settings

Configure the terminal to match your setup.

Appearance

Pick from the built-in color themes under Appearance. Themes apply instantly and persist across side-panel closes and browser restarts. See Themes for the full set.

Custom RPC Endpoint

By default, Subslot uses a Helius RPC endpoint with a built-in key. For higher limits or your own infrastructure, set a custom RPC:

1. Open Settings and expand the Custom RPC row under Network.
2. Enter your RPC URL (must start with https://).
3. Tap SAVE RPC.
4. The extension tests the connection immediately and shows the result inline — for example Custom RPC — 42ms, or an error if the endpoint is unreachable.

To revert to the default, clear the URL field (the reset control) and save. The indicator then shows Using default (Helius). Endpoint precedence is: your custom RPC first, then the server-delivered keyed endpoint, then a keyless fallback.

RPC Latency Badge

A persistent badge in the topbar shows your RPC health:

• Green dot + ms — Latency under 100ms. Excellent.
• Yellow dot + ms — 100-300ms. Acceptable.
• Red dot, or ERR — Over 300ms, or the endpoint failed to respond.

The badge refreshes every 30 seconds with a lightweight getHealth call and measures the full round-trip from your browser to the RPC and back.

Automatic Failover

Every RPC request runs through automatic failover. If your primary endpoint hangs or errors — the request times out after 8 seconds, or the transport fails — Subslot retries the same request against a configured fallback endpoint. Failover is per-call and self-heals: the moment your primary recovers, calls route back to it. You are never pinned to the fallback.

Trade Defaults

Execution engine, slippage, priority fee, and validator tip are set in the trade panel and persist between sessions. Choose your execution engine, then tune slippage, priority fee, and tip per preset. Buy presets (in SOL, or USDC in USDC Mode) are configured the same way.

Auto-Lock

Controls how long the wallet stays unlocked after your last interaction:

• Never — Stays unlocked until you manually lock or close the browser
• 5 minutes — For high-security setups
• 15 minutes — Default, a good balance of security and convenience
• 1 hour — For longer trading sessions
• 24 hours — Essentially stays unlocked all day

When auto-lock triggers, all decrypted private keys are cleared from the service worker's memory and you re-enter your password to unlock. The setting saves automatically when you change it — no save button needed.

Change Password

1. In Settings, expand the Change Password row.
2. Enter your current password.
3. Enter and confirm your new password.
4. Tap Change Password.
5. Every stored wallet is re-encrypted under a fresh salt and a new key derived from the new password.

Language & Contacts

• Language — Switch the interface language instantly.
• Saved Contacts — An address book of labelled Solana addresses for quick sends.

Privacy & Analytics

Subslot includes optional, anonymous usage analytics to track which features get used, so development can be prioritized.

• What's tracked: Anonymous feature-usage and trade-activity events.
• What's never tracked: Your private keys, seed phrase, or password.
• Opt out: Toggle Usage Analytics off under Privacy. One tap.

Reset P&L Data

Reset P&L data clears the recorded buy/sell history used for profit-and-loss (Activity, Token Launcher, and per-coin views). Your wallets and balances are untouched.
