zkSync Era uses EVM account addresses and ETH for source gas. Solana uses Solana accounts, transaction signatures, and SOL for destination activity. A 0x address is not a valid substitute for the Solana receiving address shown by the route. WBTC uses WBTC wrapped token on the source; ETH uses ETH contract token on Solana.
Base58-encoded Solana account address A Solana receipt uses a native SOL balance or SPL token account identified by mint; later token movement and account creation use SOL fees. Determine whether ETH arrives as native destination gas or as a tokenized representation. Only the native balance can directly pay that network’s fees. A compatible wallet may create or use an associated token account, and SOL—not ETH unless it is SOL—pays later Solana fees.
ETH is the native gas asset for zkSync Era. WBTC is contract-tracked and can require an allowance before transfer. A zkSync Era source executes in EraVM with native account-abstraction behavior and ETH fees before proof settlement to Ethereum.
WBTC is a custodial tokenized Bitcoin representation on smart-contract networks. Its transfers use token contracts and approvals rather than native Bitcoin inputs and outputs. On this route WBTC is the source token on zkSync Era. Its token balance, approvals, and contract transfer behavior are separate from the native coin used for network gas.
Route-specific mistakes include sending on a network other than zkSync Era; using a destination that is not valid for Solana; running out of ETH before the source transaction is submitted; assuming evm and solana addresses are interchangeable; treating a wrapped token as the native gas asset. A zkSync Era source executes in EraVM with native account-abstraction behavior and ETH fees before proof settlement to Ethereum. WBTC leaves through a custodial wrapper contract with token approval and source-chain gas; no native Bitcoin UTXO is spent by that transfer. A Solana receipt uses a native SOL balance or SPL token account identified by mint; later token movement and account creation use SOL fees. Determine whether ETH arrives as native destination gas or as a tokenized representation. Only the native balance can directly pay that network’s fees.
Wrapped Bitcoin is classified as a wrapped asset for this route. WBTC uses a wrapped contract asset on zkSync Era. The recorded zkSync Era representation uses 8 decimal places. WBTC leaves through a custodial wrapper contract with token approval and source-chain gas; no native Bitcoin UTXO is spent by that transfer.
Ethereum is classified as a native asset for this route. ETH uses a network-specific contract asset on Solana. The recorded Solana representation uses 8 decimal places. Determine whether ETH arrives as native destination gas or as a tokenized representation. Only the native balance can directly pay that network’s fees.
zkSync Era wallet, token-transfer, contract, log, and gas activity remain public, and Solana account, token, program, signature, and fee activity remain public. For this WBTC on zkSync Era to ETH on Solana path, Private Route is intended to reduce the direct visible relationship between activity around the source-side EVM 0x account address and destination-side Base58-encoded Solana account address; it does not hide either chain's public records.
No. The destination must be a Solana-compatible address. Base58-encoded Solana account address
An SPL-token receipt uses the relevant mint and token account; the wallet or route may create an associated token account when needed. SOL is used for later Solana activity.
WBTC is a contract representation on zkSync Era with 8 decimals at 0xBBeB516fb02a01611cBBE0453Fe3c580D7281011. ETH, not WBTC, pays gas unless both symbols are the same. A zkSync Era source executes in EraVM with native account-abstraction behavior and ETH fees before proof settlement to Ethereum. WBTC leaves through a custodial wrapper contract with token approval and source-chain gas; no native Bitcoin UTXO is spent by that transfer.
ETH is a contract representation on Solana with 8 decimals at 7vfCXTUXx5WJV5JADk17DUJ4ksgau7utNKj4b963voxs. SOL, not ETH, pays gas unless both symbols are the same. A Solana receipt uses a native SOL balance or SPL token account identified by mint; later token movement and account creation use SOL fees. Determine whether ETH arrives as native destination gas or as a tokenized representation. Only the native balance can directly pay that network’s fees.
WBTC leaves through a custodial wrapper contract with token approval and source-chain gas; no native Bitcoin UTXO is spent by that transfer. On receipt, Determine whether ETH arrives as native destination gas or as a tokenized representation. Only the native balance can directly pay that network’s fees.
WBTC is the deposited wrapped-asset input; ETH is the quoted native-asset output. Source allowance or native-spend rules and destination wallet/representation checks are evaluated separately.
WBTC leaves through a custodial wrapper contract with token approval and source-chain gas; no native Bitcoin UTXO is spent by that transfer. A zkSync Era source executes in EraVM with native account-abstraction behavior and ETH fees before proof settlement to Ethereum. A Solana receipt uses a native SOL balance or SPL token account identified by mint; later token movement and account creation use SOL fees. Determine whether ETH arrives as native destination gas or as a tokenized representation. Only the native balance can directly pay that network’s fees.
Requirements are checked for the live WBTC zkSync to ETH Solana 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.
