How much does it cost to bridge USDT to Optimism?
The bridge fee is free for registered EarnPark users. You only pay the Base source-chain gas fee (paid in ETH), which the network sets and EarnPark displays before you confirm. Your assets are held with Fireblocks institutional custody.
How long does the Base to Optimism transfer take?
Most Base to Optimism transfers complete in about ~2 min. Aggregated routing via 1inch is typically much faster than the Optimism native bridge, and EarnPark is operated by a UK-regulated entity.
Is it safe to bridge USDT to Optimism 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.
