What you need to know

ETH input identity and handling

Ethereum is classified as a native asset for this route. ETH uses a native asset on Arbitrum. The recorded Arbitrum 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 USDC

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 destination wallet must support the exact Polygon representation. The route converts a native-asset source into a stablecoin balance; the destination ticker alone is not a contract check.

Leaving Arbitrum L2 for Polygon L1

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

USDC output identity and receiving

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 wallet must support the destination USDC native label or contract. Receipt does not automatically supply the destination network’s gas asset.

Polygon destination execution

Polygon is a L1 EVM network in the Polygon ecosystem. POL pays destination-side network gas on Polygon. EVM 0x account address A Polygon PoS receipt follows Polygon token contracts and checkpointed execution; later movement uses POL gas rather than Ethereum L1 gas.

Arbitrum source execution

Arbitrum is a L2 EVM network in the Ethereum ecosystem. ETH pays source-side network gas on Arbitrum. EVM 0x account address On an Arbitrum source, the Nitro sequencer records L2 execution before Ethereum settlement completes; ETH funds gas and ERC-20 inputs can need approval.

Mistakes specific to ETH Arbitrum to USDC Polygon

Route-specific mistakes include sending on a network other than Arbitrum; using a destination that is not valid for Polygon; running out of ETH before the source transaction is submitted; selecting a stablecoin by ticker without checking its network contract. On an Arbitrum source, the Nitro sequencer records L2 execution before Ethereum settlement completes; ETH funds gas and ERC-20 inputs can need approval. 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 Polygon PoS receipt follows Polygon token contracts and checkpointed execution; later movement uses POL gas rather than Ethereum L1 gas. The wallet must support the destination USDC native label or contract. Receipt does not automatically supply the destination network’s gas asset.

Private Route for ETH → USDC

Arbitrum wallet, token-transfer, contract, log, and gas activity remain public, and Polygon wallet, token-transfer, contract, log, and gas activity remain public. For this ETH on Arbitrum to USDC on Polygon 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 ETH on Arbitrum to USDC on Polygon FAQs

What exactly leaves Arbitrum as ETH?

ETH is listed as the native representation on Arbitrum; ETH is used for network gas. On an Arbitrum source, the Nitro sequencer records L2 execution before Ethereum settlement completes; ETH funds gas and ERC-20 inputs can need approval. 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.

What exactly arrives on 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 receipt follows Polygon token contracts and checkpointed execution; later movement uses POL gas rather than Ethereum L1 gas. The wallet must support the destination USDC native label or contract. Receipt does not automatically supply the destination network’s gas asset.

Why does the ETH to USDC direction matter?

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. On receipt, The wallet must support the destination USDC native label or contract. Receipt does not automatically supply the destination network’s gas asset.

What changes between the source and destination asset roles?

ETH is the deposited native-asset input; USDC 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 ETH?

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. On an Arbitrum source, the Nitro sequencer records L2 execution before Ethereum settlement completes; ETH funds gas and ERC-20 inputs can need approval. A Polygon PoS receipt follows Polygon token contracts and checkpointed execution; later movement uses POL gas rather than Ethereum L1 gas. The wallet must support the destination USDC native label or contract. Receipt does not automatically supply the destination network’s gas asset.

Which stablecoin contract must this route match?

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

What funds the Arbitrum source transaction?

ETH is the native gas asset for Arbitrum. On an Arbitrum source, the Nitro sequencer records L2 execution before Ethereum settlement completes; ETH funds gas and ERC-20 inputs can need approval. ETH is recorded as native on this source.
