What exactly leaves Optimism as OP?
OP is a contract representation on Optimism at 0x4200000000000000000000000000000000000042. ETH, not OP, pays gas unless both symbols are the same. An OP Mainnet source uses sequenced OP Stack execution and ETH gas; ordinary route processing is not the same as the canonical L2 withdrawal delay. OP is transferred as a governance token; ETH remains required for OP Mainnet gas and the outbound contract must match the source network.
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 OP to SOL direction matter?
OP is transferred as a governance token; ETH remains required for OP Mainnet gas and the outbound contract must match the source network. 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?
OP 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 OP?
OP is transferred as a governance token; ETH remains required for OP Mainnet gas and the outbound contract must match the source network. An OP Mainnet source uses sequenced OP Stack execution and ETH gas; ordinary route processing is not the same as the canonical L2 withdrawal delay. 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 Optimism source transaction?
ETH is the native gas asset for Optimism. An OP Mainnet source uses sequenced OP Stack execution and ETH gas; ordinary route processing is not the same as the canonical L2 withdrawal delay. OP is token-tracked and can need approval before transfer.
What is the most dangerous wrong-network mistake here?
Sending OP on a network other than Optimism, 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 OP on OP Mainnet to SOL on BSC without KYC?
Requirements are checked for the live OP OP Mainnet 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.
