The moat · Composable volatility
Surface Studio
The live implied-volatility surface for Sui — reconstructed entirely on-chain. Every expiry is a DeepBook Predict SVI oracle; Floe reads all of them and rebuilds the full smile across moneyness and tenor. The same primitive the contract uses, floe_vol_index::vol_now, is callable by any protocol — and the enclave signs it so the number is proven, not asserted.

Reconstructing the surface from on-chain SVI oracles…
A volatility primitive, proven on-chain
From DeepBook Predict's oracle to a signed reading any protocol can compose against — four steps, no trusted feeder.
01SourceDeepBook Predict publishes a Block-Scholes SVI oracle per expiry on-chain — five parameters (a, b, ρ, m, σ) that define a whole smile.
02ReconstructWe read every live oracle and evaluate w(k) = a + b·(ρ(k−m) + √((k−m)²+σ²)) across moneyness and tenor — the full surface, not just one number.
03Compute on-chainfloe_vol_index::vol_now computes ATM IV synchronously inside any transaction — a composable volatility primitive any protocol can call for gas-free.
04AttestThe enclave signs the reading under intent 2; floe_vol_index verifies the signature on-chain — a vol number the ecosystem can trust, not assert.
The on-chain ATM number Floe reports is signed by the registered enclave under intent 2 and verified by floe_vol_index . Source oracles are DeepBook Predict — verify any expiry above.
