VeraFi
The first options market maker that publishes a cryptographic proof of honest pricing on-chain with every single quote.

Why VeraFi
Trust built into every quote
Attested Pricing
Every option quote is computed inside a Trusted Execution Environment (TEE). Tamper-proof hardware ensures the pricing model cannot be altered — not even by us.
On-Chain Proof
An attestation token is stored on-chain alongside every quote. Anyone can independently verify that the price was computed honestly inside the TEE — zero trust required.
XRPL Native
XRP users connect directly via Xaman or Crossmark. No bridge, no EVM wallet, no wrapped assets — options trading where XRP already lives.
The Flow
How it works
- 01
Request a Quote (RFQ)
User signs an RFQ Intent with their XRPL wallet — specifying underlying, strike, expiry, and size.
- 02
TEE Pricing
The intent reaches the VeraFi pricer running inside a TEE. A Black-Scholes model prices the option with live Flare FTSO oracle data.
- 03
Proof Published
The TEE generates a remote attestation token. The quote + attestation are written on-chain together before the user sees a price.
- 04
Trade or Walk
User accepts the quote with a single XRPL payment transaction, or walks away — no gas, no EVM.
The Case for VeraFi
Why this matters
- 👁️
Black-box pricing
Market makers quote options from hidden models. You have no way to know if the spread is fair or if the model was manipulated for the trade.
- 🔒
Trust assumed, not earned
Every options platform asks you to trust them. There is no verifiable record that the price you paid reflects an honest computation.
- 🌉
XRP locked out
Existing DeFi options markets require EVM wallets and wrapped assets. XRP holders face bridges, gas fees, and custodial risks just to access a quote.
- 🔐
Pricing inside a TEE
Every quote runs inside a Trusted Execution Environment. The hardware itself guarantees the model cannot be changed, replaced, or observed — not even by us.
- ⛓️
On-chain attestation
A remote attestation token is published on Flare alongside every quote. Anyone can independently verify the computation was honest before trading.
- ⚡
Native XRPL settlement
Trade directly from Xaman or Crossmark with a single XRP payment. No bridge, no wrapped token, no EVM wallet required.
