The U.S. GENIUS Act, enacted on July 18, 2025, establishes federal requirements for payment stablecoins and sets two key dates: June 9, 2026 for public comments on the joint FinCEN-OFAC AML proposal, and July 18, 2026 when implementing rules fully take effect. It limits issuance to licensed entities with reserves held only in cash, insured deposits, and short-dated U.S. Treasuries, while banning issuer-paid interest to holders. The law's rollout matters globally as stablecoins exceed $240 billion in supply, with USDT and USDC dominating market share.

JPMorgan, Citi, Bank of America, and Wells Fargo are working on a shared tokenized-deposit network slated for the first half of 2027.

Executives involved described the initiative as an on-chain payments step, while noting demand is still developing.

On May 26, 2026, Spain’s Council of Ministers approved an organic law on AI governance, positioning Spain as the first EU country to turn the EU AI Act into binding national implementation rules.

Ethereum's Clear Signing went live on May 12, 2026, with Ledger, Trezor and MetaMask switching signature prompts from hex strings to human-readable transaction details. The change targets signature-phishing losses that reached $6.27 million from 4,741 victims in Q1 2026, while keeping blind signing possible but more avoidable. The standard improves clarity for approvals such as "unlimited" token spend, though it does not remove risks tied to compromised apps or incomplete dApp metadata.

Aave later saw $8.45B in deposit outflows over the next 48 hours, alongside more than $13B leaving DeFi.

Binance Research's EVMbench benchmark published in April 2026 reports GPT-5.3-Codex succeeded 72.2% of the time when attacking vulnerable DeFi smart contracts, but reached only 36% when asked to detect issues without exploiting them. The report also puts the average cost at $1.22 per contract attempt, highlighting how cheaply AI can scale offensive testing.

Italy is rolling out a more formal crypto rulebook in 2026 through the EU's MiCA framework, including CONSOB's adoption of ESMA guidance for classifying digital tokens. The article notes estimates that more than 3.6 million Italians could hold digital assets by the end of 2025, alongside new compliance steps for firms. It also outlines tax discussions for 2026, including a possible capital gains rate up to 33% versus 26%, and the removal of the €2,000 exemption threshold.
