Chainalysis says four exploits tied to smart contracts with unverified source code led to about $37 million in losses over the past six months, including a $26 million January theft from Ethereum-based Truebit. The firm argues attackers can decompile bytecode and use automated tools to identify issues such as overflows or access-control weaknesses, and it urges source-code verification and broader audit and bug-bounty coverage for contracts holding user funds.

Mastercard said in June 2026 that OKX is among the launch partners for Agent Pay for Machines, an initiative meant to let AI agents and automated systems execute payments over the Mastercard network. The program frames a shift toward agent-initiated transactions such as purchases, invoice settlement, and subscription management, while the announcement did not specify supported tokens, regions, or a consumer rollout timeline.

Ripple is taking part in Mastercard's Agent Pay for Machines program, positioning the XRP Ledger (XRPL) and its RLUSD stablecoin for AI-enabled, autonomous payments. Mastercard said on June 10 it is collaborating with more than 30 partners to support always-on machine transactions that require controls, permissions, and dependable settlement. Ripple and RippleX executives emphasized rule-based spending limits, auditability, and regulated stablecoin settlement as agent-driven commerce expands.

Ethics provisions tied to the crypto market structure bill known as the CLARITY Act have hit a "rocky" phase as Senate lawmakers debate how the rules should be enforced. Separately, over 60 crypto firms on June 9 urged the Senate to protect developers' rights, while industry voices argued that regulatory uncertainty can be more expensive than regulation itself.

Tether said on June 10 it will lead a Series C financing of up to $1.4 billion for Germany's NEURA Robotics. The plan includes integrating Tether's open-source Wallet Development Kit into NEURA's robots so they can hold self-custodial wallets and carry out crypto payments, including micropayments, under predefined rules. NEURA is also set to test and deploy Tether's QVAC edge AI runtime inside its Neuraverse software platform.

Raydium said it will cover losses after an attacker drained about $1.34 million from five deprecated liquidity pools tied to its legacy AMM V3 program that has been phased out since 2021. The team said current users and active pools were not impacted, and stated reimbursement will be paid from Raydium's treasury while it reviews mainnet programs for vulnerabilities.

Raydium said Wednesday that its retired AMM V3 program was exploited for $1.34 million on Solana. The DEX reported losses of about 150,000 RAY, 5,600 SOL, and nearly 900,000 USDC from pools including RAY-SOL, USDC-RAY, and SRM-RAY. Raydium said the issue stemmed from insufficient validation of LP mints, while stating its current programs were not impacted.

On June 10, 2026, the U.S. Commodity Futures Trading Commission released its first proposed framework for prediction markets, outlining how it would judge whether event contracts serve the public interest or violate federal law. The draft uses a three-step review and a flexible balancing test, and would open a 45-day public comment period after finalization, taking effect 60 days after adoption.
