USDC is an issued dollar-oriented stablecoin with canonical, native, and bridged variants across networks. Contract events and issuer controls differ from a network-native gas asset. The source is a stablecoin contract or recorded native representation, while ETH is classified as native-asset. Check the quoted output rather than assuming a one-dollar source unit fixes the destination amount.
Ethereum is classified as a native asset for this route. ETH uses a native asset on Linea. The recorded Linea representation uses 18 decimal places. Determine whether ETH arrives as native destination gas or as a tokenized representation. Only the native balance can directly pay that network’s fees.
Base is a L2 EVM network in the Ethereum ecosystem. ETH pays source-side network gas on Base. EVM 0x account address 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.
This route crosses two L2 execution environments. Base settles to ethereum, while Linea settles to ethereum; each side keeps its own gas balance, token contracts, transaction hash, and settlement progress.
USDC is classified as a stablecoin for this route. USDC uses a network-specific contract asset on Base. The Base side is contract-tracked rather than a native gas balance. 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.
Linea is a L2 EVM network in the Ethereum ecosystem. ETH pays destination-side network gas on Linea. EVM 0x account address A Linea receipt is recorded on the zkEVM L2 before the related proof settles to Ethereum; later activity needs ETH on Linea and the Linea token contract.
Route-specific mistakes include sending on a network other than Base; using a destination that is not valid for Linea; running out of ETH before the source transaction is submitted; selecting a stablecoin by ticker without checking its network contract. 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. A Linea receipt is recorded on the zkEVM L2 before the related proof settles to Ethereum; later activity needs ETH on Linea and the Linea token contract. Determine whether ETH arrives as native destination gas or as a tokenized representation. Only the native balance can directly pay that network’s fees.
Base wallet, token-transfer, contract, log, and gas activity remain public, and Linea wallet, token-transfer, contract, log, and gas activity remain public. For this USDC on Base to ETH on Linea path, Private Route is intended to reduce the direct visible relationship between activity around the source-side EVM 0x account address and destination-side EVM 0x account address; it does not hide either chain's public records.
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.
ETH is listed as the native representation on Linea; ETH is used for network gas. A Linea receipt is recorded on the zkEVM L2 before the related proof settles to Ethereum; later activity needs ETH on Linea and the Linea token contract. Determine whether ETH arrives as native destination gas or as a tokenized representation. Only the native balance can directly pay that network’s fees.
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. On receipt, Determine whether ETH arrives as native destination gas or as a tokenized representation. Only the native balance can directly pay that network’s fees.
USDC is the deposited stablecoin input; ETH is the quoted native-asset output. Source allowance or native-spend rules and destination wallet/representation checks are evaluated separately.
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. 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 Linea receipt is recorded on the zkEVM L2 before the related proof settles to Ethereum; later activity needs ETH on Linea and the Linea token contract. Determine whether ETH arrives as native destination gas or as a tokenized representation. Only the native balance can directly pay that network’s fees.
USDC must match its Base representation. A ticker or target price is not enough to identify a token contract.
ETH is the native gas asset for Base. 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. USDC is token-tracked and can need approval before transfer.
