Avantis FAQ

Avantis is a decentralized perpetuals protocol on Base, available as a secondary leverage platform in Bankr. For the primary leverage platform, see Hyperliquid.

Why are my Avantis trades failing?​

Common causes:

  • Market hours — not all pairs trade 24/7. Commodities, forex, and stock index pairs (gold, EUR/USD, SPX) only trade during market hours. Crypto pairs (ETH/USD, BTC/USD) trade around the clock.
  • Position size too small — Avantis has a minimum position size per pair. Try increasing your position size.
  • Insufficient USDC — make sure you have enough USDC for collateral + gas on Base
  • Leverage out of range — check that your leverage is within the allowed range for that pair

Avantis says it's unavailable. What's happening?​

Avantis has an external API that occasionally goes down. When unavailable, Bankr will tell you clearly rather than hanging. Try again later.

You can still close existing positions even when the API is down.

My Avantis position closed unexpectedly — I didn't close it, didn't hit TP/SL, and had no automations running. What happened?​

Bankr does not close Avantis positions on your behalf. If your position closed without your command and without hitting TP/SL, it was closed by the Avantis protocol directly — this can happen during extreme market volatility when Avantis intervenes to manage risk.

To verify: look up your wallet address on Polygonscan and check the transaction that closed your position — if it was protocol-initiated, it will be triggered by the Avantis contract rather than your wallet.

Check the Avantis Twitter and Discord for announcements about your trading pair around the time of closure.

I told Bankr to sell all my tokens under $1 and it sold my $BNKR — why?​

This comes down to how Bankr interpreted "under $1" — it most likely referred to token price, and BNKR's price is under $1.

Be specific about what to exclude:

sell all tokens worth less than $10 in total value, excluding BANKR and ETH
sell my dust — anything under $5 total value, but keep BANKR

Bankr follows instructions literally — precision matters. The transaction can't be reversed; if you want your BNKR back, you'll need to buy it again.

My balance recently changed and I haven't made any transactions — why?​

This is normal. Your token balance in USD terms fluctuates with market price, but your actual token quantity hasn't changed.

If your actual token quantity has changed and you're certain you didn't make a transaction, check your wallet on Basescan for the full transaction history. If something looks off, reach out to support with your wallet address.
