What exactly leaves Arbitrum as ARB?
ARB is a contract representation on Arbitrum at 0x912ce59144191c1204e64559fe8253a0e49e6548. ETH, not ARB, pays gas unless both symbols are the same. On an Arbitrum source, the Nitro sequencer records L2 execution before Ethereum settlement completes; ETH funds gas and ERC-20 inputs can need approval. Sending ARB can require a token allowance, while ETH—not ARB—must fund Arbitrum gas. Verify the outbound ARB contract if the source is not Arbitrum.
What exactly arrives on BNB Chain as SOL?
SOL is a contract representation on BNB Chain with 18 decimals at 0x570A5D26f7765Ecb712C0924E4De545B89fD43dF. BNB, not SOL, 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 SOL receipt uses a Solana address and can fund later fees; wrapped SOL uses an SPL token account and tokenized SOL elsewhere is not native.
Why does the ARB to SOL direction matter?
Sending ARB can require a token allowance, while ETH—not ARB—must fund Arbitrum gas. Verify the outbound ARB contract if the source is not Arbitrum. On receipt, Native SOL receipt uses a Solana address and can fund later fees; wrapped SOL uses an SPL token account and tokenized SOL elsewhere is not native.
What changes between the source and destination asset roles?
ARB is the deposited token input; SOL 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 ARB?
Sending ARB can require a token allowance, while ETH—not ARB—must fund Arbitrum gas. Verify the outbound ARB contract if the source is not 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. 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 SOL receipt uses a Solana address and can fund later fees; wrapped SOL uses an SPL token account and tokenized SOL elsewhere is not native.
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. ARB is token-tracked and can need approval before transfer.
What is the most dangerous wrong-network mistake here?
Sending ARB on a network other than Arbitrum, 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 ARB on Arbitrum to SOL on BSC without KYC?
Requirements are checked for the live ARB Arbitrum to SOL 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.
