- Execute on the GBP L2 Orderbook : Place Maker/Taker limit orders on Kraken Pro or Coinbase Advanced (0.16%–0.40%) instead of paying 1.49%–2.50% instant spread.
- Withdraw to Hardware Self-Custody : Move long-term holdings to an air-gapped or EAL6+ hardware wallet while preserving transaction hashes.
- Reconcile Section 104 Pool for SA108 : Apply HMRC's 3-Stage Share Matching rules (Same-Day, 30-Day Bed & Breakfasting, Section 104 Pool) against the £3,000 AEA.
