Mastercard said on Tuesday it introduced Agent Pay for Machines (AP4M), a protocol meant to let AI agents send, receive, and settle payments across its global card network, including sub-cent microtransactions. The company says more than 30 firms such as Stripe, Coinbase, and Cloudflare are early partners, with agent permissions recorded on Polygon, Solana, and Base. Executives described AP4M as a longer-term push into machine-to-machine commerce rather than a near-term revenue driver.

Mastercard has launched its Agent Pay for Machines program for autonomous AI-to-AI settlements, with Ripple participating through the XRP Ledger and the regulated stablecoin RLUSD. The pilot documentation does not reference XRP, but RippleX says its XRPL AI Starter Kit enables agent-to-agent payments using XRP and RLUSD, including automatic DEX conversion to XRP in 3–5 seconds.

MetaMask has introduced Agent Wallet, a self-custodial product that allows AI agents to execute DeFi trades while users retain control through required checks and policy limits. The wallet includes transaction simulation, threat scanning, MEV protection, and loss coverage of up to $10,000 for eligible transactions. It launches with support for nine chains and is currently available via a CLI for a limited early-access group, with broader availability expected this summer.

ADI Predictstreet, FIFA's official prediction-market partner for the 2026 World Cup, went live on June 8 and is now accessible to U.S. users in 23 states through a co-branded Fanatics Markets "World Cup Hub."

A DeFi analyst is warning users to revoke lingering token approvals and tighten wallet hygiene ahead of Anthropic's expected public release of its Mythos AI model. In a June 9 X post, The DeFi Investor also recommended sticking to heavily audited dApps and distributing funds across multiple wallets to limit single points of failure.

MetaMask said on June 8 it introduced Agent Wallet, a self-custodial product that lets AI agents trade and use DeFi protocols under user-set rules. The early-access release supports swaps, perps, prediction markets and liquidity actions across EVM networks, plus Hyperliquid. MetaMask also includes transaction simulation, Blockaid threat detection, MEV protection and potential coverage for losses up to $10,000 under its terms.

On June 9, 2026, investigator ZachXBT said Humanity Protocol's $32M incident looked "possibly staged" after multiple wallets were drained and 100 million H tokens were minted without authorization on BNB Chain. CoinMarketCap data showed H fell -86% from $0.7183 to $0.099, while separate on-chain notes said selling activity appeared concentrated on DEXs rather than centralized venues.

Humanity Protocol reported a widening security incident on June 9 that grew from early estimates above $5 million to losses exceeding $32 million. Investigators said stolen assets were largely swapped into ETH and also involved an unauthorized mint of 100 million H tokens, while founder Terence Kwok confirmed a private-key compromise and told users to avoid the bridge and liquidity pools. The H token fell as much as 81% and was quoted at $0.1411 amid the fallout.

Hyperliquid’s portion of all exchange perpetuals trading volume climbed above 7% for the first time, reaching 7.6% as of June 8. The move came during a market drawdown, with total crypto market cap down nearly 26% year to date and Bitcoin touching $59k on June 5. HYPE fell roughly 10% after Arthur Hayes said he closed his entire HYPE position, even as Hyperliquid’s platform volume continued to rise.

Arthur Hayes returned to buying Hyperliquid’s HYPE after selling nearly $18 million last week, a move that was followed by an almost 20% pullback. He accumulated 33,978 HYPE worth about $2.09 million as the token held near $60 after dropping from its $75 all-time high. Separately, rising TVL, fees, and on-chain activity point to a recovery supported by network fundamentals rather than trading flows alone.
