Summary
The week of June 5th reflected a pattern that has grown more defined over recent months: institutional capital is engaging onchain infrastructure through direct product integrations and purpose-built platforms, rather than through custodied wrappers or exchange-listed products. Combined circulating supply of the two largest dollar-pegged stablecoins approached $265 billion, while lending yields on major onchain markets continued to offer rates competitive with traditional financial instruments.
The most significant development of the week was Morpho's Vault Summit at the New York Stock Exchange on June 5th, co-hosted by S&P Global, where institutional allocators and onchain vault curators met on traditional finance's most prominent venue. On June 2nd, OpenSea confirmed that its planned perpetual futures product would run on Hyperliquid's builder code infrastructure, marking the first major NFT platform committing to a DeFi derivatives backend.
Stablecoin developments
Circle (USDC): Circle's USDC circulating supply is approximately $75 billion. USDC earns approximately 3.45% APY on Aave V3 at current utilization; Morpho vaults curated for USDC offer 4–7% APY, with variation driven by curator strategy and market conditions.
Tether (USDT): Tether's USDT circulating supply is approximately $188 billion. Tether continues to broaden USDT's cross-chain availability through USDT0 infrastructure, which enables movement across more than 20 blockchains via a single API.
Sky Money (USDS): Sky's USDS circulating supply is approximately $11 billion. The Sky Savings Rate (SSR) is 3.75% APY. This week, the Sky Frontier Foundation published its first transparency report, covering governance and financial activity from inception through March 2026. The report disclosed a $16 million USDS investment in the Stablecoin Development Corporation ($SDEV), a publicly traded entity that now holds 9.15% of SKY's total token supply.
Maple Finance (syrupUSDC, syrupUSDT): Maple Finance holds approximately $2 billion in TVL across Ethereum and Solana. Maple's syrup products earn approximately 4–4.7% APY, funded by institutional loan origination across the protocol's credit facilities.
Protocol developments
Aave: Aave's TVL is approximately $12 billion. On June 2nd, a governance proposal was submitted to refresh signer composition across Aave's seven budget and asset-holding SAFEs as the DAO's service provider roster consolidates.
Lido Finance: stETH currently earns 2.51% APY. Lido Finance's TVL is approximately $14.2 billion. This week, Lido set forth a design and implementation proposal for Staking Router v3, which would unlock a more flexible, efficient Ethereum staking protocol through reallocated stake via consolidations, large validator deposit support, and lean validator management.
Morpho: Morpho's TVL is $11.8 billion. On June 5th, Morpho hosted Vault Summit at the New York Stock Exchange, co-hosted by S&P Global. The conference brought together protocol teams, asset managers, and risk curators to evaluate onchain vault infrastructure at institutional scale.
Spark: Spark closed May 2026 with $6.5 billion in Savings TVL, $3 billion in SparkLend TVL, and $2.4 billion deployed through the Spark Liquidity Layer across multiple chains, for a combined total of approximately $11.9 billion. Depositors currently earn 3.6% APY with sUSDS.
Hyperliquid: Hyperliquid carries $5.8 billion in TVL and generates more than $800 million in annualized fees. On June 2nd, OpenSea confirmed plans to build perpetual contract trading on Hyperliquid's builder code infrastructure. OpenSea has not published a launch date, supported assets, or leverage parameters, but the announcement marks the first major NFT platform committing to Hyperliquid as a derivatives backend.
Pendle: Pendle holds approximately $1.5 billion in TVL across 234 tracked pools. The Saturn sUSDat pool, linked to STRC dividends, drove elevated PT and YT demand this week. New stablecoin pools wOUSD and apyUSD currently offer double-digit yields to liquidity providers.

The dominant pattern this week is institutional infrastructure maturation. Morpho's Vault Summit at the NYSE reflects a structural step: onchain vaults are being evaluated alongside traditional asset management products by allocators who manage capital at scale. OpenSea's planned move into perpetuals on Hyperliquid adds a second data point, showing that specialized DeFi infrastructure is being embedded as a backend layer by platforms with large existing user bases.
