Regulatory framing — United Kingdom

BNB swaps are CGT disposals under HMRC. Cross-chain BNB → ETH/BTC almost always routes through CEX (third-party-bridge exploit history ~$2B+ cumulative 2021-2024 makes bridge route risky). BSC DEX swaps NOT broker-reported. UK active BSC DeFi users generate substantial reporting overhead.

Primary regulators: FCA · HMRC

Common gotchas

Cross-chain BNB via bridges = exploit risk. CEX route preferred.
BSC swap volume per active user can be high (memecoin/farm trading).
BNB-as-gas: every BSC swap consumes BNB.
Approval revocation matters more on BSC (higher scam-contract incidence).
Section 104 pool + 30-day matching apply.
