SPDR S&P 500 ETF (Ondo Tokenized ETF) spyon

SPYon is Ondo's tokenized representation of exposure to the State Street SPDR S&P 500 ETF Trust (SPY), the exchange-traded fund designed to track the S&P 500 Index. It is issued through Ondo Global Markets (BVI) Limited and is intended primarily for non-U.S. investors subject to eligibility and jurisdictional restrictions. The token is identified by the SPYon ticker and the `on` suffix denotes an Ondo/onchain representation.

The reference asset is a diversified, float-adjusted, market-cap-weighted large-cap U.S. equity portfolio spanning all eleven GICS sectors. State Street describes SPY as the first U.S.-listed ETF, launched January 22, 1993, and designed to correspond generally to the price and yield performance of the S&P 500 before expenses.

SPYon is an economic-exposure token rather than direct ownership of SPY shares. Holders do not receive shareholder voting, statutory information, or other shareholder rights in the underlying securities. Ondo describes its tokenized stocks as fully backed total-return trackers: dividends are reinvested net of withholding taxes, so token economics can diverge from a simple one-token/one-share relationship over time.

Traditional U.S. ETFs such as SPY trade through conventional brokerage and exchange infrastructure, have market-hour constraints, and can be difficult for many non-U.S. users to access. They also do not natively plug into blockchain wallets, smart contracts, or DeFi venues.

SPYon addresses this access and composability gap by wrapping exposure to SPY in a transferable token with onchain settlement, fractional ownership, and generally 24/5 availability. It does not eliminate market risk: SPY's equity exposure remains volatile, token prices can differ from the reference asset, and availability and participation depend on Ondo's eligibility, KYC, jurisdictional, operational, and platform-risk rules.

Ondo Global Markets issues SPYon against U.S. stocks, ETFs, and cash held with U.S. broker-dealers. Ondo says an independent Verification Agent reviews backing daily and a Security Agent holds a security interest for token holders; its documentation also describes a bankruptcy-remote SPV, overcollateralization, daily attestations, smart-contract audits, monthly reconciliations, and annual audits.

The token is designed as a total-return tracker. Economic exposure includes the underlying asset's performance plus reinvested dividends, net of withholding tax. Accordingly, one token does not necessarily represent exactly one SPY share and its quoted price may not always equal SPY's market price. On Solana and BNB Chain, Scaled UI can display balances and prices in a share-like format without changing the underlying economics.

Eligible users can mint or redeem for cash or stablecoins through Ondo's platform, while secondary-market transfers and DeFi integrations provide additional liquidity paths. Ondo states minting and burning are instant and there are no mint or burn fees, although quoted execution prices can differ slightly from the price at which Ondo buys or sells the underlying. SPYon is available on Ethereum, BNB Chain, and Solana, with transferability to HyperEVM via bridge; trading is generally 24/5 but may pause for sessions, corporate actions, risk limits, or other exceptions.
