ETH input identity and handling

Ethereum is classified as a native asset for this route. ETH uses a native asset on zkSync Era. The recorded zkSync Era representation uses 18 decimal places. Native ETH can fund both transfer value and gas on its selected network. If the source is WETH or another tokenized form, approval and unwrap or exchange logic differ.

Receiving stablecoin DAI

DAI is a crypto-backed dollar-oriented stablecoin whose canonical and bridged contracts vary by network. Its peg design does not make two network representations interchangeable. The destination wallet must support the exact Base representation. The route converts a native-asset source into a stablecoin balance; the destination ticker alone is not a contract check.

zkSync Era to Base L2 handoff

This route crosses two L2 execution environments. zkSync Era settles to ethereum, while Base settles to ethereum; each side keeps its own gas balance, token contracts, transaction hash, and settlement progress.

DAI output identity and receiving

Dai is classified as a stablecoin for this route. DAI uses a network-specific contract asset on Base. The recorded Base representation uses 18 decimal places. The receiving wallet must recognize the exact destination DAI contract. Peg intent does not guarantee that a bridged representation has the same liquidity or issuer path.

Base destination execution

Base is a L2 EVM network in the Ethereum ecosystem. ETH pays destination-side network gas on Base. EVM 0x account address A Base receipt belongs to the Base L2 balance and token contract, not Ethereum L1; later activity needs ETH specifically on Base.

zkSync Era source execution

zkSync Era is a L2 EVM network in the Ethereum ecosystem. ETH pays source-side network gas on zkSync Era. EVM 0x account address A zkSync Era source executes in EraVM with native account-abstraction behavior and ETH fees before proof settlement to Ethereum.

Mistakes specific to ETH zkSync Era to DAI Base

Route-specific mistakes include sending on a network other than zkSync Era; using a destination that is not valid for Base; running out of ETH before the source transaction is submitted; selecting a stablecoin by ticker without checking its network contract. A zkSync Era source executes in EraVM with native account-abstraction behavior and ETH fees before proof settlement to Ethereum. Native ETH can fund both transfer value and gas on its selected network. If the source is WETH or another tokenized form, approval and unwrap or exchange logic differ. A Base receipt belongs to the Base L2 balance and token contract, not Ethereum L1; later activity needs ETH specifically on Base. The receiving wallet must recognize the exact destination DAI contract. Peg intent does not guarantee that a bridged representation has the same liquidity or issuer path.

Private Route for ETH → DAI

zkSync Era wallet, token-transfer, contract, log, and gas activity remain public, and Base wallet, token-transfer, contract, log, and gas activity remain public. For this ETH on zkSync Era to DAI on Base 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.
