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 Base as SOL?
SOL is a contract representation on Base with 9 decimals at 0x311935Cd80B76769bF2ecC9D8Ab7635b2139cf82. ETH, not SOL, pays gas unless both symbols are the same. A Base receipt belongs to the Base L2 balance and token contract, not Ethereum L1; later activity needs ETH specifically on Base. 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 ETH to SOL 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, 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?
ETH is the deposited native-asset 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 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 Base receipt belongs to the Base L2 balance and token contract, not Ethereum L1; later activity needs ETH specifically on Base. 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. ETH is recorded as native on this source.
What is the most dangerous wrong-network mistake here?
Sending ETH on a network other than Arbitrum, or using an address that is not valid for Base, can prevent detection or delivery. Match both network labels and representations to the active route.
Can I swap ETH on Arbitrum to SOL on Base without KYC?
Requirements are checked for the live ETH Arbitrum to SOL Base 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.
