Stellar
Deterministic PT oracle
Zero-coupon-bond pricing for Stellar Principal Tokens.
The Stellar oracle calculates a Principal Token price from a zero-coupon-bond model:
price = future PT value / (1 + implied APY)^(time remaining / one year)The price moves toward the configured future PT value as maturity approaches. At or after maturity, the returned price equals the current future PT value.
What the oracle uses
- One PT address.
- A maturity timestamp.
- An initial implied APY.
- A configurable future PT value.
- Output-decimal metadata.
The oracle does not read an AMM, a TWAP, Reflector, the PT's live exchange rate, or a Blend reserve. It is a deterministic model whose output is fully determined by time and its configured parameters.
Long-maturity instances require periodic TTL maintenance. See the oracle integration reference for fixed-point behavior, permissions, and deployment constraints.
