Main News Coverage
1. EU Crypto Assets Regulation (MiCA) – Implementation Phase Begins
On March 1, the European Commission activated the first compliance window under the Markets in Crypto-Assets (MiCA) framework. Asset‑backed e‑money tokens (AETTs) now face stricter reserve requirements, while stablecoins are subject to the new B2B‑centered transparency rules. Early adopters report a 12‑hour onboarding delay for new issuers, but the regulation is praised for giving the market a clearer legal architecture.
2. U.S. SEC Advances “Crypto‑Friendly” Guidance for Exchanges
The Securities and Exchange Commission released a Regulatory Framework for Crypto‑Asset Exchanges on March 14. The guidance, published after a 2023 summit with industry leaders, clarifies that non‑fungible tokens (NFTs) can be classified as securities if they carry an expectation of profits derived solely from the issuer’s efforts. Exchanges gaining a certainty index will receive a reduced compliance fee for the next fiscal year.
3. Polygon’s Layer‑2 Upgrade 3.0 Achieves Mainnet Launch
Polygon’s Layer‑2 “Polygon 3.0” rollout on March 20 introduced a novel zero‑trust rollup architecture. By bundling 2,500 transactions per second (tps) into a single proof, the network reduced gas fees by 78% and increased throughput to 6,000 tps. Analysts project a 35% short‑term uplift in DEX activity, particularly for lesser‑known projects seeking cheaper deployment.
