FBX Protocol — hard-deflationary sound money with friendly yield vaults
FBX Protocol is a DeFi protocol on Polygon, live since
November 2021. Its token FBX was minted exactly once
(21,000,000) in the contract's constructor — which has no mint function
and no owner — so no one can ever create more. Supply only falls: the
protocol's contracts burn FBX (for example, minting EP burns FBX), and
well over a third of the original supply is already burned forever.
Around that scarce asset sit beginner-friendly, self-custodial vaults —
stake, swap and earn, with no forced lock-ups: withdraw from any vault at
any time.
Why it's trustworthy (all verifiable)
- No inflation possible — FBX has no mint function and no owner role; 21M minted once, supply only burns down.
- No owner on the core contracts — FBX, EP staking, Auto-FBX, wstEP, the Fire Pool and the swap router aren't even Ownable (no pause/upgrade/drain).
- Immutable — standalone contracts, no upgrade proxy.
- Self-custodial — withdraw from any vault at any time; locks are only ever opt-in, and can be left early. The protocol never holds your keys.

Vaults & venues
- Auto-FBX — auto-compounding FBX vault.
- wstEP — auto-compounding EP (Elemental Particles) vault, an ERC-4626 share.
- Fire Pool — EP/FBX liquidity pool that also powers the EP↔FBX swap.
- DCI vault — deposit USDT, earn the Dynamic Composite Index (DCI).
- EP staking — stake EP, earn FBX.
- Firesight — a no-loss prediction game over real Polymarket questions (only this venue is no-loss; the rest of the protocol is not): deposit EP, which stays yours and is always withdrawable; its yield funds the prizes, and you call outcomes with the Energy your deposit generates.
- Swap — EP, FBX, USDT0 and DCI in one transaction, best venue per hop.
