USDC and USDT: 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. USDT is issued through ERC-20, TRC-20, SPL, and other network-specific contracts. The ticker does not determine the token standard, contract, issuer controls, or destination address model. 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 Polygon. The recorded Polygon representation uses 6 decimal places. 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.

USDT output identity and receiving

Tether is classified as a stablecoin for this route. USDT uses a network-specific contract asset on zkSync Era. The recorded zkSync Era representation uses 6 decimal places. Confirm whether the output is ERC-20, TRC-20, SPL, or another USDT standard; a wallet supporting one standard may not credit another.

From Polygon L1 into zkSync Era L2

Polygon source execution occurs on L1, while zkSync Era delivery occurs on a separate L2 ledger that settles to ethereum. POL pays source gas and ETH is the destination gas asset; identical-looking wallet addresses do not merge the balances or transaction histories.

Polygon source execution

Polygon is a L1 EVM network in the Polygon ecosystem. POL pays source-side network gas on Polygon. EVM 0x account address A Polygon PoS source uses its validator/checkpoint system and POL gas; its token contracts and checkpoints are separate from Ethereum L1.

zkSync Era destination execution

zkSync Era is a L2 EVM network in the Ethereum ecosystem. ETH pays destination-side network gas on zkSync Era. EVM 0x account address A zkSync Era receipt belongs to EraVM account state and uses ETH for later fees; proof settlement to Ethereum remains distinct from L2 delivery.

Mistakes specific to USDC Polygon to USDT zkSync Era

Route-specific mistakes include sending on a network other than Polygon; using a destination that is not valid for zkSync Era; running out of POL before the source transaction is submitted; selecting a stablecoin by ticker without checking its network contract. A Polygon PoS source uses its validator/checkpoint system and POL gas; its token contracts and checkpoints are separate from Ethereum L1. 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 receipt belongs to EraVM account state and uses ETH for later fees; proof settlement to Ethereum remains distinct from L2 delivery. Confirm whether the output is ERC-20, TRC-20, SPL, or another USDT standard; a wallet supporting one standard may not credit another.

Private Route for USDC → USDT

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

Swap USDC on Polygon to USDT on zkSync Era FAQs

What exactly leaves Polygon as USDC?

USDC is a contract representation on Polygon with 6 decimals at 0x3c499c542cEF5E3811e1192ce70d8cC03d5c3359. POL, not USDC, pays gas unless both symbols are the same. A Polygon PoS source uses its validator/checkpoint system and POL gas; its token contracts and checkpoints are separate from Ethereum L1. 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 zkSync Era as USDT?

USDT is a contract representation on zkSync Era with 6 decimals at 0x493257fD37EDB34451f62EDf8D2a0C418852bA4C. ETH, not USDT, 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. Confirm whether the output is ERC-20, TRC-20, SPL, or another USDT standard; a wallet supporting one standard may not credit another.

Why does the USDC to USDT 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, Confirm whether the output is ERC-20, TRC-20, SPL, or another USDT standard; a wallet supporting one standard may not credit another.

What changes between the source and destination asset roles?

USDC is the deposited stablecoin input; USDT 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 Polygon PoS source uses its validator/checkpoint system and POL gas; its token contracts and checkpoints are separate from Ethereum L1. A zkSync Era receipt belongs to EraVM account state and uses ETH for later fees; proof settlement to Ethereum remains distinct from L2 delivery. Confirm whether the output is ERC-20, TRC-20, SPL, or another USDT standard; a wallet supporting one standard may not credit another.

Which stablecoin contract must this route match?

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

What funds the Polygon source transaction?

POL is the native gas asset for Polygon. A Polygon PoS source uses its validator/checkpoint system and POL gas; its token contracts and checkpoints are separate from Ethereum L1. USDC is token-tracked and can need approval before transfer.

Can I swap USDC on Polygon to USDT on zkSync without KYC?

Requirements are checked for the live USDC Polygon to USDT zkSync 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.
