SPDR S&P 500 ETF Trust Token Hits $18M in DeFi Deposits

The SPDR S&P 500 ETF Trust has found an unlikely home in the decentralized finance (DeFi) space, with its tokenized tracker certificate, SPYx, accumulating $18.3 million in deposits across multiple venues.

SPYx is a token that mirrors the underlying SPY ETF share, held by a custodian in a 1:1 ratio. It's available on Solana as an SPL token and on Ethereum as an ERC-20 token, allowing for around-the-clock trading in fractional amounts.

The product launched on June 30, 2025, with early assets under management of $6.9 million. Chainlink handles the price feed and oracle layer, while FlowDesk provides liquidity support.
