Stablecoin Developments
Circle (USDC): USDC circulating supply stands at approximately $74 billion. No protocol-level governance changes were published during the week. USDC remains the primary deposit and collateral asset across Aave V3 Ethereum and leading Morpho vaults, with variable supply rates in the mid-single-digit range depending on utilization.

Maple Finance (syrupUSDC / syrupUSDT): On May 21st, Maple launched the Maple Borrower Hub, a consolidated platform for institutional borrowers to manage onchain credit. The hub provides multi-entity organization views, live loan health metrics with margin call and liquidation thresholds, in-platform onchain actions including loan acceptance, payment, and refinancing, and email-based authentication alongside wallet access. Maple's existing dashboard remains available through June 30th.
Protocol Updates
Aave: On May 16th, Aave participated in coordination efforts around asset recovery following the April KelpDAO bridge exploit, working with other protocols on seizure procedures.

Lido Finance: stETH APY is currently at 2.35%, based on DeFiLlama data. Lido's TVL stands at $18.85 billion. No governance proposals or protocol updates were published during the week.
Morpho: On May 18th, Tempo, a stablecoin payments blockchain backed by Stripe and Paradigm, announced its integration with Morpho to bring onchain lending and borrowing to its network. The integration lets fintechs and enterprises building on Tempo lend, borrow, and earn yield on idle stablecoin balances through Morpho's lending infrastructure. Tempo counts Visa, Mastercard, Revolut, Shopify, Klarna, and UBS as network partners and raised $500 million last year at a $5 billion valuation.
Spark: Spark holds $5.38 billion in TVL as of May 22nd. SparkLend's wBTC deposit cap is incrementally scaling from 3,000 to 30,000 wBTC via cap automator following the governance approval on May 11th, adding 500 wBTC every 12 hours.
Hyperliquid: HYPE reached a new all-time high near $63 on May 21st before pulling back, driven by continued platform momentum following the HIP-4 prediction market launch earlier this month. HIP-4 brought zero-fee outcome markets to Hyperliquid, running inside the same account structure as perpetual futures positions.
Pendle: Pendle's TVL is currently at $1.59 billion. Several institutional yield pools from Ember Protocol, including eACRED, eEARN, and eTHIRD, are active on the platform ahead of their July 2026 maturities, offering fixed-rate exposure to private credit and delta-neutral stablecoin strategies.
Access All of Onchain Finance with Yield.xyz
The week's defining pattern was DeFi lending rails being embedded inside fintech infrastructure at scale. Morpho's Tempo integration gives fintechs building on a payments-focused blockchain access to curated lending markets without building per-protocol integrations. Maple's Borrower Hub extends the same logic to the borrower side: institutional treasury teams can now manage the full onchain credit lifecycle from a single interface designed for enterprise access patterns, not crypto-native tooling.
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.
