What you need to know

ETH input identity and handling

Ethereum is classified as a native asset for this route. ETH uses a native asset on Scroll. The recorded Scroll representation uses 18 decimal places. 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.

Scroll to Arbitrum L2 handoff

This route crosses two L2 execution environments. Scroll settles to ethereum, while Arbitrum settles to ethereum; each side keeps its own gas balance, token contracts, transaction hash, and settlement progress.

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.

SOL output identity and receiving

Solana is classified as a native asset for this route. SOL uses a network-specific contract asset on Arbitrum. The recorded Arbitrum representation uses 9 decimal places. 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.

Scroll source execution

Scroll is a L2 EVM network in the Ethereum ecosystem. ETH pays source-side network gas on Scroll. EVM 0x account address A Scroll source executes in the zkEVM and is later included in a proof batch to Ethereum; Scroll contract identity must be verified independently.

EVM-to-EVM execution boundary

Scroll and Arbitrum can use the same 0x address syntax, but they are separate networks with different chain identifiers, gas balances, token contracts, and transaction histories. The recorded settlement context includes ethereum, so L1 and L2 confirmation behavior should not be assumed identical.

Mistakes specific to ETH Scroll to SOL Arbitrum

Route-specific mistakes include sending on a network other than Scroll; using a destination that is not valid for Arbitrum; running out of ETH before the source transaction is submitted. A Scroll source executes in the zkEVM and is later included in a proof batch to Ethereum; Scroll contract identity must be verified independently. 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. 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. 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.

Private Route for ETH → SOL

Scroll wallet, token-transfer, contract, log, and gas activity remain public, and Arbitrum wallet, token-transfer, contract, log, and gas activity remain public. For this ETH on Scroll to SOL on Arbitrum 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 ETH on Scroll to SOL on Arbitrum FAQs

What exactly leaves Scroll as ETH?

ETH is listed as the native representation on Scroll; ETH is used for network gas. A Scroll source executes in the zkEVM and is later included in a proof batch to Ethereum; Scroll contract identity must be verified independently. 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 Arbitrum as SOL?

SOL is a contract representation on Arbitrum with 9 decimals at 0x2bcC6D6CdBbDC0a4071e48bb3B969b06B3330c07. ETH, not SOL, pays gas unless both symbols are the same. 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. 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. A Scroll source executes in the zkEVM and is later included in a proof batch to Ethereum; Scroll contract identity must be verified independently. 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. 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 Scroll source transaction?

ETH is the native gas asset for Scroll. A Scroll source executes in the zkEVM and is later included in a proof batch to Ethereum; Scroll contract identity must be verified independently. ETH is recorded as native on this source.

What is the most dangerous wrong-network mistake here?

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