Summary
DeFi's lending markets entered the week with capital still rotating toward protocols perceived to have managed collateral risk responsibly in the aftermath of April's KelpDAO exploit. On May 9th, a federal judge authorized the transfer of 30,766 ETH to an Aave-controlled multisig, formally clearing the last legal obstacle in the KelpDAO recovery.
The week's most significant structural development came on May 13th, when Hyperliquid retired USDH and named Coinbase as the official USDC treasury deployer under the AQAv2 framework, one of the largest single-protocol stablecoin transitions of the year. Circle's launch of Agent Stack on May 12th completed a week defined by institutional infrastructure building: USDC expanding across agentic payment rails, regulated investment products reaching DeFi's highest-volume venue, and the first recovery funds from the year's largest exploit clearing a US federal court.
Stablecoin Developments
Circle (USDC): Circle reported Q1 2026 results on May 11, with supply rising 28% year-over-year to $77 billion and onchain transaction volume up 263% to $21.5 trillion. On May 12th, Circle launched Agent Stack, a developer toolkit for AI agents: agent wallets, a command-line interface, an agent marketplace, and a nanopayments protocol capable of processing USDC transfers at sub-cent scale without gas fees. Moreover, USDC is now natively live on 34 blockchain networks. Current yields include: Aave Ethereum V3 USDC supply runs 3-5% APY; leading Morpho curated vaults are returning 4-7% APY depending on curator and collateral.
Tether (USDT): Tether ****launched a developer grants program on May 11th, funding builders on its open technology stack with no cap on total payouts, tied to specific technical deliverables. USDT supply sits near $190 billion, with total assets of approximately $192 billion against $183.5 billion in liabilities. Current yields: Aave Ethereum USDT supply runs approximately 2-4% APY depending on utilization; leading Morpho vaults are returning 4-8% APY.
Sky Money (USDS): Sky holds the Sky Savings Rate at 3.75% APY for sUSDS, with supply above $9 billion. The protocol's most recent structural change remains the May 7th Liquidity Layer spell: Aave Avalanche USDC offboarded due to illiquidity conditions, and Aave Core USDT deposits capped at zero following a recent risk event.
Maple Finance: syrupUSDC is currently yielding 5.2% APY and syrupUSDT is yielding 4.4% APY, sourced from overcollateralized institutional loans. Maple's assets under management have grown from $500 million to nearly $4 billion over the past year, with the protocol now deployed on Ethereum, Solana, Arbitrum, and Base.
Protocol Developments
Aave: Aave cleared a key legal hurdle on May 9th when Judge Margaret Garnett modified a prior asset freeze, authorizing the transfer of 30,766 ETH valued at approximately $71 million to an Aave-controlled multisig wallet. The ruling shields onchain governance participants from liability under the prior restraining notice, closing the last major legal obstacle in the rsETH recovery process. Aave V3 holds approximately $14.4 billion in total value locked.
Lido Finance: stETH ****is currently yielding approximately 2.5% APY with $19.5 billion in total value locked. The V3 protocol upgrade continues to roll out with permissionless stETH minting for all stVaults and extended minting caps for node operators.
Morpho: Morpho expanded its Coinbase Lending integration on May 13th, adding Solana as eligible collateral for USDC loans of up to $100,000, the first major non-EVM Layer 1 added to the platform. Morpho holds approximately $7.6 billion in total value locked across lending markets.
Spark: Spark continued operating under the May 7th Liquidity Layer adjustments: Aave Avalanche USDC remains offboarded and Aave Core USDT deposits remain capped at zero. SparkLend holds approximately $5.2 billion in TVL.
Hyperliquid: Hyperliquid retired USDH this week, naming Coinbase as the official USDC treasury deployer under the upgraded AQAv2 framework. Coinbase acquires USDH brand assets, stakes HYPE for AQAv2 activation, and shares the majority of USDC reserve yields with the ecosystem. Hyperliquid holds approximately 70% of decentralized perpetuals trading volume by market share, with $5.5 billion in total value locked.

The week's most significant structural development is the Hyperliquid-Coinbase stablecoin alignment: Hyperliquid retired its own stablecoin and chose USDC under institutional treasury management, alongside the launch of the first regulated investment vehicle for its native asset. The protocol is consolidating around institutional-grade infrastructure at the stablecoin, custody, and investment product level simultaneously.
These developments share the same underlying logic: the protocols attracting durable capital now have transparent collateral frameworks, institutional treasury management, and clear operational architecture. Yield.xyz connects developers and allocators to more than 3,000 onchain opportunities across 80+ networks, covering staking, lending, perpetuals trading, and DeFi vaults through a single onchain integration. When the market consolidates around protocols with institutional backing, your integration moves with it.
