Converting stablecoin USDC into ARB

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 ARB is classified as token. Check the quoted output rather than assuming a one-dollar source unit fixes the destination amount.

ARB output identity and receiving

Arbitrum is classified as a governance or utility token for this route. ARB uses a network-specific contract asset on Arbitrum. The Arbitrum side is contract-tracked rather than a native gas balance. A receiving wallet should show the exact ARB contract on the destination. Receipt does not fund ETH gas for later token movement.

BNB Chain source execution

BNB Chain is a L1 EVM network in the BNB Chain ecosystem. BNB pays source-side network gas on BNB Chain. EVM 0x account address A BNB Smart Chain source uses BNB gas and BEP-20 contracts; a familiar 0x account does not turn a BEP-20 deposit into ERC-20.

From BNB Chain L1 into Arbitrum L2

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

USDC input identity and handling

USDC is classified as a stablecoin for this route. USDC uses a network-specific contract asset on BNB Chain. The recorded BNB Chain representation uses 18 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.

Arbitrum destination execution

Arbitrum is a L2 EVM network in the Ethereum ecosystem. ETH pays destination-side network gas on Arbitrum. EVM 0x account address An Arbitrum receipt appears on the Nitro L2 ledger under an Arbitrum token contract or native ETH balance; later spending needs Arbitrum ETH while L1 settlement continues 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. An Arbitrum receipt appears on the Nitro L2 ledger under an Arbitrum token contract or native ETH balance; later spending needs Arbitrum ETH while L1 settlement continues separately. A receiving wallet should show the exact ARB contract on the destination. Receipt does not fund ETH gas for later token movement.
