What exactly leaves Arbitrum as DAI?
DAI is a contract representation on Arbitrum with 18 decimals at 0xDA10009cBd5D07dd0CeCc66161FC93D7c9000da1. ETH, not DAI, 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. DAI leaves through its network-specific stablecoin contract and can require approval; the collateral design does not make a bridged DAI contract canonical.
What exactly arrives on Scroll as WBTC?
WBTC is a contract representation on Scroll with 8 decimals at 0x3C1BCa5a656e69edCD0D4E36BEbb3FcDAcA60Cf1. ETH, not WBTC, pays gas unless both symbols are the same. A Scroll receipt is an L2 native or contract balance whose proof settlement to Ethereum is a separate milestone; later activity uses ETH on Scroll.

Why does the DAI to WBTC direction matter?

On receipt, WBTC arrives as a wrapper-contract token and must not be sent onward to a native Bitcoin address without an explicit unwrap or bridge path.
What changes between the source and destination asset roles?
DAI is the deposited stablecoin input; WBTC is the quoted wrapped-asset output. Source allowance or native-spend rules and destination wallet/representation checks are evaluated separately.
What should be matched before sending DAI?
