What USDC representation leaves Base?
USDC is a contract representation on Base at 0x833589fcd6edb6e08f4c7c32d4f71b54bda02913. ETH, not USDC, pays gas unless both symbols are the same. A Base source transaction is sequenced on the OP Stack rollup and later settles to Ethereum; Base ETH and Base token approvals remain on the L2 ledger. The source wallet sends the exact USDC native or contract representation selected by the route; contract USDC can require approval and the chain’s native gas asset.
What USDC representation arrives on zkSync Era?
USDC is a contract representation on zkSync Era at 0x1d17cbcf0d6d143135ae902365d2e5e2a16538d4. ETH, not USDC, pays gas unless both symbols are the same. A zkSync Era receipt belongs to EraVM account state and uses ETH for later fees; proof settlement to Ethereum remains distinct from L2 delivery. The wallet must support the destination USDC native label or contract. Receipt does not automatically supply the destination network’s gas asset.
Does the same USDC ticker guarantee the same ledger form?
No. This bridge keeps the asset intent while moving between a USDC contract token and a USDC contract token. Match the source and output details in the live quote.
Which gas balances matter for this bridge?
A Base source transaction is sequenced on the OP Stack rollup and later settles to Ethereum; Base ETH and Base token approvals remain on the L2 ledger. A zkSync Era receipt belongs to EraVM account state and uses ETH for later fees; proof settlement to Ethereum remains distinct from L2 delivery. The bridge output does not automatically fund every later gas need.
What destination address should be used?
EVM 0x account address Do not substitute a Base address merely because a wallet displays both networks.
What wrong-direction mistake can prevent delivery?
Sending on a network other than Base, selecting a representation not listed by the quote, or entering an address invalid for zkSync Era can prevent normal detection or receipt.
Can I bridge USDC from Base to ZKsync Era without KYC?
Requirements are checked for the live USDC Base to ZKsync Era quote. Verification requirements can depend on the provider, amount, jurisdiction, and current route. Sasquatch does not verify this route as universally no-KYC; check the live flow before continuing.
