What you need to know

SOL input identity and handling

Solana is classified as a native asset for this route. SOL uses a network-specific contract asset on Polygon. The recorded Polygon representation uses 9 decimal places. Native SOL leaves a Solana account through a signed transaction and pays the fee; wrapped or tokenized SOL uses a token account or external contract 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.

AVAX output identity and receiving

Avalanche is classified as a native asset for this route. AVAX uses a network-specific contract asset on BNB Chain. The recorded BNB Chain representation uses 18 decimal places. Native Avalanche receipt belongs on C-Chain and can fund later gas; an AVAX token on another chain remains a contract balance.

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.

EVM-to-EVM execution boundary

Polygon 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 SOL Polygon to AVAX BNB Chain

Route-specific mistakes include sending on a network other than Polygon; using a destination that is not valid for BNB Chain; running out of POL before the source transaction is submitted. A Polygon PoS source uses its validator/checkpoint system and POL gas; its token contracts and checkpoints are separate from Ethereum L1. Native SOL leaves a Solana account through a signed transaction and pays the fee; wrapped or tokenized SOL uses a token account or external contract 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 Avalanche receipt belongs on C-Chain and can fund later gas; an AVAX token on another chain remains a contract balance.

Private Route for SOL → AVAX

Polygon 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 SOL on Polygon to AVAX 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.

Swap SOL on Polygon to AVAX on BNB Chain FAQs

What exactly leaves Polygon as SOL?

SOL is a contract representation on Polygon with 9 decimals at 0xd93f7E271cB87c23AaA73edC008A79646d1F9912. POL, not SOL, 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. Native SOL leaves a Solana account through a signed transaction and pays the fee; wrapped or tokenized SOL uses a token account or external contract instead.

What exactly arrives on BNB Chain as AVAX?

AVAX is a contract representation on BNB Chain with 18 decimals at 0x1CE0c2827e2eF14D5C4f29a091d735A204794041. BNB, not AVAX, pays gas unless both symbols are the same. 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 Avalanche receipt belongs on C-Chain and can fund later gas; an AVAX token on another chain remains a contract balance.

Why does the SOL to AVAX direction matter?

Native SOL leaves a Solana account through a signed transaction and pays the fee; wrapped or tokenized SOL uses a token account or external contract instead. On receipt, Native Avalanche receipt belongs on C-Chain and can fund later gas; an AVAX token on another chain remains a contract balance.

What changes between the source and destination asset roles?

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

What should be matched before sending SOL?

Native SOL leaves a Solana account through a signed transaction and pays the fee; wrapped or tokenized SOL uses a token account or external contract instead. A Polygon PoS source uses its validator/checkpoint system and POL gas; its token contracts and checkpoints are separate from Ethereum L1. 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 Avalanche receipt belongs on C-Chain and can fund later gas; an AVAX token on another chain remains a contract balance.

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. SOL is token-tracked and can need approval before transfer.

What is the most dangerous wrong-network mistake here?

Sending SOL on a network other than Polygon, or using an address that is not valid for BNB Chain, can prevent detection or delivery. Match both network labels and representations to the active route.

Can I swap SOL on Polygon to AVAX on BSC without KYC?

Requirements are checked for the live SOL Polygon to AVAX BSC 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.
