AVAX input identity and handling

Avalanche is classified as a native asset for this route. AVAX uses a native asset on Avalanche. The recorded Avalanche representation uses 18 decimal places. On Avalanche C-Chain, native AVAX funds both the transfer value and gas; on another chain, an AVAX-labelled contract behaves as a token input instead.

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.

BNB output identity and receiving

BNB is classified as a native asset for this route. BNB uses a native asset on BNB Chain. The recorded BNB Chain representation uses 18 decimal places. Native BSC receipt can fund BNB gas, while externally bridged BNB arrives as a representation that needs the destination chain’s gas token.

Avalanche source execution

Avalanche is a L1 EVM network in the Avalanche ecosystem. AVAX pays source-side network gas on Avalanche. EVM 0x account address An Avalanche source route uses C-Chain Snowman execution and AVAX gas; X-Chain or P-Chain balances are not valid C-Chain deposits.

EVM-to-EVM execution boundary

Avalanche and BNB Chain can use the same 0x address syntax, but they are separate networks with different chain identifiers, gas balances, token contracts, and transaction histories.

Mistakes specific to AVAX Avalanche to BNB BNB Chain

Route-specific mistakes include sending on a network other than Avalanche; using a destination that is not valid for BNB Chain; running out of AVAX before the source transaction is submitted. An Avalanche source route uses C-Chain Snowman execution and AVAX gas; X-Chain or P-Chain balances are not valid C-Chain deposits. On Avalanche C-Chain, native AVAX funds both the transfer value and gas; on another chain, an AVAX-labelled contract behaves as a token input instead. A BNB Smart Chain receipt uses the BEP-20 contract or native BNB balance selected by the route; later token movement needs BNB gas. Native BSC receipt can fund BNB gas, while externally bridged BNB arrives as a representation that needs the destination chain’s gas token.

Private Route for AVAX → BNB

Avalanche 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 AVAX on Avalanche to BNB 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.
