How to Track zkSync in the UK

CryptoLens is the UK's first free multi-chain crypto analytics platform. Just paste any Ethereum-compatible or Solana wallet address and we'll scan all 7 EVM chains (Ethereum, BSC, Polygon, Arbitrum, Optimism, Base, Avalanche) plus Solana to find your ZK holdings. No sign-up required — your portfolio value appears in GBP within seconds.

UK Capital Gains Tax on zkSync

HMRC treats ZK as a capital asset. Every time you sell, swap, or spend your zkSync, it's a taxable disposal. For the 2025/26 tax year, you have a £3,000 annual exempt amount. Gains above that are taxed at 10% for basic-rate taxpayers and 20% for higher-rate taxpayers. CryptoLens scans your on-chain history to calculate your exact liability using Section 104 pooling, with an optional HMRC-ready PDF export for Pro members.

zkSync Fumble Checker

The Fumble Checker analyses your wallet for any ZKyou sold before it reached its all-time high. It compares your sell transactions against ATH prices and shows you the profit you left on the table. Share your fumble score on Twitter/X to compare with friends — it's become one of our most viral features.
