Ethereum is a programmable blockchain where applications run via smart contracts. It underpins large parts of DeFi and many L2 scaling networks.
Why it could matter in 2026
- Largest developer ecosystem for smart contracts
- Core infrastructure for DeFi and L2s
- Extensive tooling and standards
Key risks
- Network fees can spike during demand
- Smart contract risk across the ecosystem
- Competition from other L1s/L2s
