Brazilian Congressman Lincoln Portela has introduced Bill 2.901/2026, aiming to establish a permanent financial sandbox for blockchain and tokenization testing. The proposed framework, overseen by the Central Bank of Brazil, seeks to support fintech and digital finance platforms by providing a regulatory environment tailored to company size, with simplified standards for smaller startups. The bill emphasizes the importance of proportionate regulatory requirements and prohibits excessive bureaucratic measures. The sandbox will facilitate testing in areas such as financial flow tracking, AI-driven credit applications, and programmable payments. It also encourages infrastructure sharing and database compatibility, while adhering to data protection laws. Additionally, the bill proposes a national system for digital financial integrity to enhance cybersecurity and combat financial crime in cryptocurrency transactions. Companies violating regulations could face fines up to 20% of their annual profits. The bill is set for discussion in various House committees.
