Lightning Wallet is one path to fast trading. Fast Mode is the other — and it’s for traders who want to keep their funds in their main wallet but still trade without per-trade popups.

How Fast Mode works

You sign a single transaction that delegates spending authority — up to a capped amount — to a session key for a limited window. During the session:
  • Trades sign automatically, no popups.
  • Spending is hard-capped at the amount you delegated.
  • The session key cannot withdraw your funds, only execute swaps.
  • You can revoke the session at any time with one tap.
When the session expires, or when you revoke, the delegation evaporates and your main wallet is back to fully manual signing.

Why this exists

Some traders find custodial wallets — even sandboxed, withdrawable ones like Lightning Wallet — philosophically unacceptable. They want every dollar to remain in a wallet whose seed they control. Fast Mode respects that. Your funds stay in your wallet. The session key has no withdrawal power. It can only:
  • Sign swap transactions
  • Up to the capped amount
  • Until the session ends
This is delegated authority, not transferred custody. The functional analog is signing a limit order with a broker who can execute against it but cannot move your portfolio anywhere else.

The guardrails

The session key is constrained at multiple levels:

Capped notional

You set the maximum total SOL the session can spend. When that cap is reached, signing automatically halts and you must explicitly extend.

Capped per-trade size

A maximum size per individual trade prevents a single runaway transaction.

Capped slippage

The session key can only sign trades whose slippage is within bounds you’ve set.

Capped priority fee

The session key cannot agree to absurd priority fees beyond the level you’ve authorised.

Allowed swap routes

The session key can only sign swaps against allow-listed routes — the same routes Dequan uses anyway. It cannot sign arbitrary contract calls.

Always-visible revoke

A revoke button is always one tap away. Hitting it cancels the session immediately.

When you’d use Fast Mode vs Lightning Wallet

  • Traders who require strict non-custody
  • Trades against your main wallet’s existing balance, no funding required
  • Sessions where you know roughly how much you intend to deploy
  • Hardware-wallet users who want one signing event instead of dozens
Both modes work. You can run either, or neither, or switch between them. They are not competing — they are different points on the same speed/control trade-off curve.

Tier requirements

Fast Mode is available on Sniper and Apex tiers. Lightning Wallet is available on every tier including Scout, the free tier. The reason is that Fast Mode requires more careful operational guardrails (active session monitoring, faster revoke pipelines) that scale with usage tier. If you’re on Scout and want fast one-tap trading, Lightning Wallet is the recommended path.

Revoking

One button. The session ends immediately. Any signed-but-not-yet-broadcast transactions are dropped. Subsequent trades require a fresh session arm or fall back to standard wallet signing. You should revoke when:
  • You’re done trading for the session
  • You step away from your computer
  • You hit your delegated cap and don’t intend to renew
  • Anything feels wrong
There is no penalty for frequent revoke/re-arm cycles. The system treats them as normal operation.
