Ex-OECD adviser: DeFi outside EU DAC8/CARF as 2026–2029 rollout advances

The EU's DAC8, built on the OECD's CARF, requires crypto exchanges and custodians to start gathering user activity data in 2026, while decentralized finance remains out of scope. Taxbit's Colby Mangels, a former OECD adviser, said the intermediary-first approach is intentional and could change as AML standards evolve; a June 2025 FATF report shows regulators still struggle to assign DeFi accountability.
