Underwriters

Underwriters create and price BlockFinaX events and seed their initial collateral. The Stellar build retains the existing role for FX desks, banks, fintech venues and other qualified counterparties. Naming a potential user category does not establish a commercial partnership or permission to distribute the product.

Create an event​

Set pair, initial rate, strike, payout limit, direction (Cap or Floor), expiry, premium rate, allowed SAC asset, external-LP policy, and creator fee configuration. Attach an approved oracle policy and seed amount. The create transaction requires the creator's Stellar authorization and transfers actual seed collateral; an API quote is not collateral.

The proposed builder validates the strike and limit geometry, positive initial rate, supported pair, future expiry, asset identity, bounds, and funded maximum exposure. It returns the exact invocation and transfers for review. Creation fees and seed capital are displayed separately.

Pricing choice​

Keep the existing advisory pricing engine and self-priced mode. The underwriter selects the event premium rate using its market data and risk appetite. Optional engine attestation, if implemented, is a Stellar-bound signature rather than an EVM recovery-address check. The contract's price policy must be visible before hedgers or external LPs participate.

Earnings and authority​

The creator receives the configured loyalty-fee accrual and the premium and capital share attributable to its seeded LP deposit. Creator earnings use a separate withdrawal path. Creator authority does not include changing an active event's payoff or taking another user's claim. Private-pool and institutional approval rules must state what the contract enforces and what remains a business workflow.

Production gates​

Actual oracle coverage, allowed distribution, security review, and Stellar account compatibility must be confirmed before a production event is offered. Testnet events use test assets and do not represent real customer protection. See institutional integration.
