The end of payment authorisation: why AI agents need intelligent contracts - payment cards such as Amex, Mastercard and Visa have transformed commerce by making electronic authorisation ubiquitous. AI agents change the commercial problem. As software begins negotiating, purchasing and settling for people and businesses, then payment approval becomes only one part of a wider agreement. Will ‘intelligent contracts’ (otherwise known as smart contracts) combine identity, authority, tax, insurance and programmable settlement, whilst recognising that card companies, banks and existing payment systems may remain important rails within a broader architecture for autonomous global commerce at scale?
Prediction markets bet on trustlessness, asset managers bet on the basis - prediction markets are evolving from forecasting tools into tradeable event-risk markets, but their promise of trustlessness remains overstated. Hyperliquid, Polymarket and Kalshi rely on different combinations of validators, token voters, exchange discretion and regulation to define outcomes. For asset managers, the opportunity lies in pricing gaps between event contracts and options, futures, bonds, equities and commodities. Yet settlement wording, liquidity, custody, insider information and capital lock-up can quickly turn apparent arbitrage into expensive basis risk.
Your hardware wallet is merely a key: self-custody is harder than most people think - the recent Coldcard security incident has re-ignited debate over one of cryptocurrency’s oldest principles: self-custody. Whilst holding your own private keys removes dependence on exchanges and custodians, it also transfers responsibility for security, recovery and governance entirely to the owner. As digital assets become increasingly institutional and AI begins managing financial decisions, the challenge is no longer simply protecting private keys. It is designing custody architectures that remain secure, recoverable and usable when technology, software or people inevitably fail.
How lawyers recovered $1.5 million in stolen USDC in just nine working days - how lawyers, investigators and blockchain forensic firms helped recover 1.5m USDC within nine working days from being instructed through to recovery, and how the most “nuclear” of legal tools can be used to secure fast and substantial results.
