How much does it cost to bridge BTC to Base?

How long does the Arbitrum to Base transfer take?

Is it safe to bridge BTC to Base on EarnPark?
EarnPark is operated by a UK-regulated entity, uses Fireblocks for institutional-grade custody, and routes liquidity through 1inch. As with any crypto activity, bridging and earning carry risk — returns are not guaranteed and past performance does not indicate future results.
