8.1 Non-Custodial by Design

Capture Engine & Capture Terminal

• Read-only:

  • They do not hold private keys.

  • They do not sign or broadcast transactions.

  • They do not custody assets.

• They:

  • Fetch quotes from DEXs/aggregators.

  • Compute spreads and net profit estimates.

  • Display opportunities and stats.

If you only use Engine + Terminal:

All risk is concentrated in whatever you use to execute trades (wallet, exchange, custom bot).

Capture Bot

• Still non-custodial at the protocol level:

  • Funds live in your wallet(s).

  • Bot interacts via permissions you explicitly grant (programmatic access, delegation, etc.).

• You can always:

  • Revoke permissions (depending on design).

  • Move funds out of that wallet.

Non-custodial ≠ risk-free; it just means we don’t physically hold your coins.
