The protocol's guarantees are limited to what the code can assure. This page lists the risk factors that fall outside those guarantees and that must be considered before any decision.
Bitcoin volatility
The floor is denominated in sats, not dollars. In BTC, it does not decrease; that is the extent of the guarantee. In USD, the floor's value varies with the price of Bitcoin: a 30% drop in BTC reduces the dollar value of the guaranteed minimum by the same proportion.
Limits of the Boost guarantee
The guaranteed floor of the Burn Vault Boost is a redemption floor. It does not assure market price: when the market trades above it, the Boost does not affect the return. The guarantee covers the remaining quota of eligible EVA, finite by design; outside of it, the minimum redemption value is the Core's base floor, which is lower. The remaining quota can be checked in the live table in Burn Vault.
Dependence on wBTC
The vaults' backing is wBTC, Bitcoin represented as an ERC-20 token, with custody of the underlying BTC by BitGo. This is an external dependency: a serious failure of wBTC's custody or parity would affect the value of the backing, outside the protocol's control.
wBTC is the oldest and most liquid Bitcoin wrapper on the market, which mitigates the risk without eliminating it.
Mining operation
The pace at which the floor rises depends on deposits, and deposits depend on a physical operation: energy, hardware, maintenance and the local regulatory environment. Rising energy costs or loss of efficiency reduce the BTC produced. In those scenarios, the floor does not decrease, but rises more slowly.
Bitcoin halvings reduce the block reward over time and affect the entire mining industry.
Regulation and partners
Regulatory changes in Paraguay (where the mining farms are located), in the regulation of stablecoins and wrappers, or in the markets where EVA is traded may affect the operation and the ecosystem. The project's commercial partnerships may also change or end.
How to evaluate
Evaluating the protocol separates what is guaranteed by code from what is expected from the operation and the market:
| Guaranteed (immutable code) | Expected (operation and market) |
|---|---|
| The floor in sats does not decrease | The pace at which the floor rises |
| Redemption at any time at the Burn Price | The market premium over the floor |
| Fixed supply, permanent burn | The floor's value in dollars |
| No one withdraws from the vault without burning | Continuity of mining and partnerships |
