How this service works
Basis Ledger live read: tokenized ETFs on Robinhood Chain (USO, SPY, QQQ, GLD, SLV) against the funds they mirror. On chain USDG pool price at grade A, the fund's newest print and whether its session is open, the futures move since the fund closed, the expected off hours price with a band, and the basis. Read every fifteen minutes.
Output
A structured snapshot per tokenized ETF (USO, SPY, QQQ, GLD, SLV) containing: on-chain USDG pool price at grade A quality, the fund's latest NAV print, whether the fund's trading session is currently open, futures price move since the fund last closed, the expected off-hours price with a confidence band, and the basis (on-chain price minus NAV). Data is refreshed every 15 minutes.
Example use cases

“Check the current basis between the tokenized SPY and QQQ on Robinhood Chain and the real ETFs — I want to know if either is trading at a significant premium or discount right now.”
After-hours ETF price estimation
“What is the expected off-hours price for the tokenized GLD and SLV on Robinhood Chain, and what is the uncertainty band around those estimates?”
Futures-driven price monitoring

Endpoint
GEThttps://api.realedger.xyz/v1/basisWhen to prefer
Use this endpoint when you need real-time basis monitoring for tokenized ETFs specifically on Robinhood Chain, want both the on-chain price and the real fund NAV in a single call, need futures-implied off-hours pricing with a band, or are running a basis trading or arbitrage strategy against tokenized equity/commodity ETFs. Prefer this over generic DeFi price feeds when the Robinhood Chain tokenized ETF ecosystem is your specific target.
