As Sweden and Norway reconsider their ambitions of becoming fully cashless societies due to concerns about centralized digital payment vulnerabilities, Ethereum co-founder Vitalik Buterin has emphasized Ethereum's potential role as a decentralized backup payment platform in times of crisis.
Sweden has been a global leader in digital payments, with only 10% of transactions still involving cash in 2025. However, due to emerging worries about cyber threats, civil defense, and geopolitical instability—especially related to the Russia-Ukraine conflict—Swedish authorities are encouraging citizens to retain a week's worth of cash to ensure resilience during emergencies.
Buterin pointed out that the centralized infrastructure underpinning current digital payment systems is fragile and vulnerable to failures or hostile attacks, which is why cash remains necessary as a fallback.
He suggested that Ethereum’s decentralized network could provide a more robust and private alternative if it can evolve to be sufficiently resilient. Enhancements in privacy and decentralization would be critical for Ethereum to credibly act as a financial fallback during crises.
Ethereum is already making strides by introducing features to improve scalability and functionality, but technical challenges such as transaction costs still limit its adoption in emergency scenarios.
While crypto payment adoption is growing, experts like Mercuryo CEO Petr Kozyakov argue that cryptocurrencies will coexist with fiat currency rather than fully replacing it, as crypto is used when it is the easier or more practical option.
