The UK will adjust its Individual Savings Account (ISA) policy in April 2026, and retail investors will no longer be able to purchase cryptocurrency exchange-traded notes (ETNs) with ISAs, as they are reclassified as assets that do not meet ISA rules.

Foresight News reported that Tempo announced the launch of a native token standard, TIP-20, which is specifically designed for stablecoins and payment use cases. It is based on the existing ERC-20 standard on Ethereum and EVM-compatible chains, and is fully backward compatible. It adds transfer notes, compliance controls, and reward distribution features on top of ERC-20. The TIP-20 standard allows for the issuance of stablecoins tailored to specific payment use cases while meeting operational and compliance requirements. Any USD-denominated TIP-20 stablecoin can be used to pay transaction fees on Tempo. In the future, Tempo plans to support paying fees using non-USD stablecoins.
