BlazePhoenix V2 is pre-deployment and under audit; this is the intended flow. The classic chicken-and-egg of self-custody is that you need the native gas token to make your first move, but you have not swapped for it yet. V2 targets gasless entry: the user signs an authorisation, and execution is submitted so the gas is abstracted away from that first interaction.

## Signatures, not custody

The design leans on signed, scope-limited authorisations — permit-style token approvals and account-abstraction style execution — so the user proves intent with a signature while never handing over custody. The floor and result verification still apply, so gasless does not mean trustless-of-outcome: the same on-chain guarantees bind the sponsored transaction as any other.

**Verify it yourself:** On mainnet launch, confirm a gasless swap on /verify still enforces the same minOut floor as a self-funded one — sponsorship must not relax settlement guarantees
