As you might have noticed (and asked yourself) – some vaults on bitcoinvn.io/staking currently don’t show any APR.

A bug? Zero payout, really?

No – it is a deliberate design choice.

The FDAPR (Fully Diluted APR = vault at 100% utilization) indicates the current APR. Example: at 500 BNB the vault pays 0.11%, which means at 5 BNB the vault would pay ~11%.

The display is disabled for smaller vaults to prevent misleading APR figures. Rewards are still paid out for all eligible swaps involving the underlying asset – sometimes at quite extreme rates.

To avoid misleadingly high “outsized” APR numbers, BitcoinVN applies minimum thresholds before APRs are displayed publicly.

Vaults must meet*:

  • A minimum balance of around $500, and
  • A quarterly turnover of (at least) roughly $3,000 [at which point the FDAPR number display activates]

The reason is simple: with too few funds in a vault, even small payouts can result in exaggerated percentage returns – for example, a vault with just $100 staked could temporarily show triple-digit APRs. These figures are technically correct but would rapidly normalize once more users join in.

At which point you’ll inevitably have users complaining that “it was a trap” – when they realize the displayed 587% APR doesn’t hold once more funds flow into a (relatively) empty vault (Read more about how our vault and APR design works here).

By setting these requirements, BitcoinVN aims to keep the displayed APRs meaningful and reflective of real-world performance rather than short-term statistical noise.

Even if APRs aren’t visible yet, all active vaults continue to generate rewards for current stakers – the displayed data will update automatically once the vaults reach the operational thresholds.

How often are the APR numbers updated?

The BitcoinVN staking page doesn’t display updates in real time.

APR figures are generally refreshed several times per day as new data flows in from our backend.

So if you don’t see changes immediately after a deposit or reward payout, give it a little time – the displayed APR should adjust within a couple of hours. 🙂

Note: The displayed APR may lag behind actual payouts – it’s a reference figure, not a live reflection of current rewards.

The BitcoinVN staking page serves as a lagging indicator, offering an approximate overview of current market conditions for our staking (liquidity provision) product on the swap exchange. It’s meant for orientation – not as a future performance guarantee.
