Aztec Investigates $2M Exploit of a Product It Retired in 2022 Aztec is looking into a roughly $2 million exploit, but the target was a deprecated payments product, not the live network. The team said the affected contract is an immutable stage 2 rollup that was sunset in 2022, and that Aztec Labs holds no admin keys or control over the system. That detail is the whole story for risk: code that cannot be paused or upgraded keeps running exactly as deployed, long after the team has moved on, and any value left sitting in it stays exposed. Immutability removes admin-key risk, the thing most users worry about, and replaces it with the opposite problem, that nobody can intervene when something breaks. It is a clean reminder to check whether the contract holding your funds is still maintained, which is part of what our security scores are built to surface. (The Block)

Tether Winds Down aUSDT and the Alloy Platform Tether is discontinuing aUSDT and shutting the "Alloy by Tether" platform to sharpen its focus. aUSDT was a stablecoin over-collateralized by XAUT, Tether's gold token, an attempt to back a dollar unit with a hard asset rather than reserves. Winding it down narrows Tether back toward its core USDT franchise and away from experimental collateral models. For yield users the takeaway is narrow but useful: synthetic and gold-backed dollar units carry product-discontinuation risk that plain reserve-backed stablecoins do not, and that risk is rarely priced into the headline APY. Stablecoin yields still anchor most conservative strategies, and the comparison across issuers sits on our stablecoin yields view. (The Block)

Solana DeFi TVL Holds at $4.83B as Lending Rates Stay Muted Solana DeFi total value locked sits near $4.83 billion, with SOL trading around $71.40, down about 1.2% on the day. Lending rates remain compressed: the top USDC supply yields run 4.24% on Kamino Lend and 4.14% on Jupiter Lend, the latter holding roughly $415 million in deposits. Liquid staking still pays the most reliable real yield on the chain, with JitoSOL near 5.62% APY across about $701 million in stake. The pattern is the same one we have flagged all month, muted lending demand and staking carrying the floor, which is what stable-capital allocators should weigh before chasing thin lending spreads. Live numbers across every pool are on the SOL yields page. (Source: DeFiLlama, CoinGecko, live data June 18)

Ireland Names Crypto Among Its Top Financial-Crime Threats Ireland published a new National Risk Assessment that lists crypto-asset misuse among the country's leading financial-crime risks, paired with a 30-point action plan that tightens checks on crypto funds. The move fits the broader European pattern under MiCA and the EU anti-money-laundering package, where member states are formalizing how exchanges and custodians screen flows. None of this changes onchain yields directly, but it raises the compliance bar for the fiat ramps that most users depend on to move in and out of those yields. Regulatory friction at the edges is becoming a real input to where liquidity settles. (Decrypt)

Bitcoin Holds Near $64K as ETFs Post Another Outflow Bitcoin is trading around $64,092, down about 1.6% on the day, after U.S. spot Bitcoin ETFs logged an $82.2 million net outflow. Glassnode noted that improving onchain liquidity may be forming a floor, a more constructive read than the price action alone suggests. Ether tracked lower in sympathy at roughly $1,740, off 1.3%. The split worth watching is between fund flows that keep leaking and onchain metrics that are quietly repairing, a gap that tends to resolve toward the onchain signal once forced selling exhausts. For anyone parking capital through the chop, the BTC and ETH yield views compare where idle balances earn while they wait. (The Block)

Range Raises $8.3M for Stablecoin Compliance Tooling Compliance startup Range raised $8.3 million from fintech and crypto VCs to build infrastructure for finance teams running both stablecoins and fiat. "Stablecoins and fiat are converging, and finance teams need one platform to run both safely and at scale," CEO Andres Monteoliva said. The round is a small but telling marker: the money is flowing toward the plumbing that lets institutions actually use stablecoins, not just hold them. That plumbing is the precondition for the next leg of stablecoin yield demand. (The Block)
