USDC and DAI: two stablecoin ledgers

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. 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 route changes both asset identity and network representation; dollar-oriented pricing does not remove issuer controls, liquidity spread, contract, or receiving-network checks.

USDC input identity and handling

USDC is classified as a stablecoin for this route. USDC uses a network-specific contract asset on zkSync Era. The zkSync Era 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.

DAI output identity and receiving

Dai is classified as a stablecoin for this route. DAI uses a network-specific contract asset on BNB Chain. The recorded BNB Chain 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.

Leaving zkSync Era L2 for BNB Chain L1

zkSync Era inclusion and its ethereum settlement are distinct from final receipt on BNB Chain. The live route, rather than a generic rollup withdrawal assumption, determines the provider path and timing for this direction.

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.

BNB Chain destination execution

BNB Chain is a L1 EVM network in the BNB Chain ecosystem. BNB pays destination-side network gas on BNB Chain. EVM 0x account address A BNB Smart Chain receipt uses the BEP-20 contract or native BNB balance selected by the route; later token movement needs BNB gas.

Mistakes specific to USDC zkSync Era to DAI BNB Chain

Route-specific mistakes include sending on a network other than zkSync Era; using a destination that is not valid for BNB Chain; 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. 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 BNB Smart Chain receipt uses the BEP-20 contract or native BNB balance selected by the route; later token movement needs BNB gas. 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 USDC → DAI

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

A zkSync Era source executes in EraVM with native account-abstraction behavior and ETH fees before proof settlement to Ethereum. 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 exactly arrives on BNB Chain as DAI?

DAI is a contract representation on BNB Chain with 18 decimals at 0x1AF3F329e8BE154074D8769D1FFa4eE058B1DBc3. BNB, not DAI, pays gas unless both symbols are the same.

Why does the USDC to DAI direction matter?

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, 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.

What changes between the source and destination asset roles?

USDC is the deposited stablecoin input; DAI is the quoted stablecoin output. Source allowance or native-spend rules and destination wallet/representation checks are evaluated separately.

What should be matched before sending USDC?

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 zkSync Era source executes in EraVM with native account-abstraction behavior and ETH fees before proof settlement to Ethereum. A BNB Smart Chain receipt uses the BEP-20 contract or native BNB balance selected by the route; later token movement needs BNB gas. 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.

Which stablecoin contract must this route match?

USDC must match its zkSync Era representation. DAI must match the quoted BNB Chain representation. A ticker or target price is not enough to identify a token contract.

What funds the zkSync Era source transaction?

ETH is the native gas asset for zkSync Era. A zkSync Era source executes in EraVM with native account-abstraction behavior and ETH fees before proof settlement to Ethereum. USDC is token-tracked and can need approval before transfer.
