What runs on Arbitrum: the native asset and the tokens issued on the network. Every page links out with contracts, facts, and deep links.
The numbers first: Arbitrum produces a block about every 0.25 seconds, runs Optimistic Rollup, launched in 2021, and prices its gas in ETH. Those facts shape everything a holder does on it. Transactions confirm at the chain's cadence, fees move with demand for block space, and any wallet holding a little of the native asset can transact anything in the roster below. The U.CASH router treats Arbitrum as one venue among many: same-chain routes through its liquidity, cross-chain routes quoted beside them, and the best net number wins after fees.
Picking Arbitrum for any given holding is therefore a settlement decision rather than an investment thesis: the same token issued on two chains tracks the same price, and what differs is how fast it moves, what it costs to move, and which wallets hold it natively. Merchants feel the same choice from the other side, deciding which chain's form of an asset to accept at checkout; buyers rarely feel it at all, because the router absorbs the geography and the invoice keeps its denomination.
For payments people, the roster below is the checkout surface: any asset on it can be a checkout asset, settling non-custodial to a merchant wallet, and any of them can be the asset a buyer pays with from their Arbitrum wallet. The page for each asset carries its confirmation policy, its contracts, and the facts a diligence pass wants.
8 network flavors, each with its own page.
