On June 11, 2026, CoinFello announced the public launch of Fello 1, an upgrade that lets users interact with any EVM-compatible smart contract and aims to simplify DeFi liquidity provision. The release adds support for opening LP positions on Uniswap V2, V3, and V4, executing multi-step transactions, and using a self-custodial delegation model where users keep control of wallets and keys.

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.

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.

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." The platform supports fiat and crypto funding and offers FIFA-branded prediction contracts as Gibraltar's licensing timeline and company links draw scrutiny ahead of the tournament's June 11 opener.

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.
