FAQ
How much does it cost to bridge USDC from Arc to Optimism?
Stablane charges no platform fee. You only pay Circle's fee and gas on Arc. There is no Fast tier from Arc, so there is no protocol fee. Automatic delivery adds a forwarding fee of about 0.052 USDC; that is the only fee in Standard mode. With Standard (self-claim) Circle charges nothing and you pay gas on Optimism yourself. These numbers were quoted when this page was generated; the quote shown before you confirm is what applies.
How long does it take to bridge USDC from Arc to Optimism?
Arc reaches finality within seconds, so Standard mode arrives in about 30 sec and no Fast tier is needed. The USDC lands at the same address on Optimism.
What do I need for gas when bridging from Arc?
Nothing extra: Arc is Circle's stablecoin L1 and uses USDC for gas, usually well under one cent, taken from your USDC balance. The Max button keeps about 0.5 USDC aside for gas. Arc finalizes in seconds, so no Fast tier is needed from Arc.
Is it safe to bridge with Stablane?
Stablane never holds your funds and has no contracts or liquidity pools of its own. Your wallet calls Circle's CCTP V2 contract on Arc to burn USDC; after Circle attests, the CCTP contract on Optimism mints the same amount. The risk is the same as holding USDC itself.
Why is it 1:1 with no slippage?
CCTP burns and mints instead of swapping: whatever is burned on Arc is minted on Optimism (minus the Circle fees above), with no exchange rate or slippage. You receive native USDC issued by Circle on Optimism, not a bridged token such as USDC.e.
What if the transfer fails or does not arrive?
A transfer has two steps: burn on Arc, mint on Optimism. Once the burn succeeds your funds are safe: History shows progress, and on another device you can recover it with the burn transaction hash from Arc. If automatic delivery stalls you can claim on Optimism yourself (needs a little ETH for gas).
Are Safe and other smart contract wallets supported?
Not yet. CCTP mints to the same address on Optimism, and a contract wallet's address on another chain may not belong to you. Stablane detects contract wallets and blocks them; please use a regular wallet (EOA) such as MetaMask or Rabby.
Is there a minimum or maximum amount?
Stablane sets no limits, and transfers from Arc use Standard mode, which has no cap. The amount must exceed the forwarding fee (about 0.052 USDC); otherwise choose self-claim.
