An address is a 20-byte identifier that can hold a balance and, when it carries code, execute it. Gas on Arc is paid in USDC, so the balance shown for an address is denominated in dollars rather than in a volatile asset.

The function list on this tab is generated from the contract’s ABI, and an ABI comes from verified source. Nothing has been published for 0x511534be… yet, so Arcscan has no names, no argument types and no encoding rules for it — and it will not guess them from the deployed selectors, because a guessed signature that encodes a call wrongly can move money to the wrong place. If you have the source, publishing it takes a minute.
