Owning ACX: Uses, Networks and Risks

ACX is Across Protocol’s governance and incentive token; it is separate from the tokens you bridge. Across is an optimistic cross-chain bridge secured by UMA’s optimistic oracle. It is designed to move assets between supported chains using a shared liquidity pool and competing relayers, with a no-slippage fee model described by the project.

ACX can be used to take part in governance over protocol parameters and to incentivize liquidity providers and relayers. Holding ACX does not, by itself, mean you are providing liquidity, running a relayer, or earning rewards. Check the current proposal and program rules before assuming a particular holding or activity gives you a say or a payment.

If you use Across, review the route, destination network, quoted output and fees before signing. The bridge’s service is what moves assets; buying or holding ACX is not required to understand the transaction and does not guarantee that a bridge transfer will succeed.

ACX has been issued on Ethereum, Boba, Optimism, Arbitrum and Polygon. These are networks where the token exists, not a promise that every Across route supports all five. Check the selected network and token details in your wallet and on the Across interface before sending or bridging anything.

ACX is not the native gas token of those chains. You generally need the relevant network’s gas token to pay transaction fees when moving ACX or interacting with a contract. A wallet must support the network you choose, and the receiving platform must accept ACX on that same network.

When transferring ACX between wallets or platforms, match the network on both sides. A token sent using an unsupported network or to an address you cannot control may be difficult or impossible to recover. If a wallet shows multiple ACX entries, verify the token contract through a trusted project interface rather than choosing by ticker alone; tickers can be copied by unrelated tokens.

ACX has a maximum supply of 1 billion tokens. As of November 8, 2026, about 705 million were circulating, with total supply reported at 1 billion. Circulating supply can change as tokens enter or leave circulation, so treat these figures as a dated snapshot rather than a permanent count.

Supply matters because it helps you understand dilution and the amount of token ownership represented by a holding. The difference between circulating supply and the maximum supply means not all ACX was circulating at that date. It does not tell you when additional tokens might enter circulation or how holders will vote on protocol decisions.

Do not treat a low token price as evidence that ACX is inexpensive in valuation terms. Price, market capitalization and fully diluted valuation can move quickly, and a fully diluted figure assumes the maximum supply is counted. None of these measures predicts future demand or performance.

You can store ACX in a wallet that supports the network on which your tokens are held. For longer-term storage, keep your recovery phrase offline and private, use a strong device passcode, and consider a hardware wallet if it suits your needs. Never share a recovery phrase or approve a transaction you do not understand; a legitimate support agent should not need your phrase.

Before using Across, check the source and destination networks, token amounts, quoted output and fees. A bridge transaction can be exposed to smart-contract bugs, oracle or relayer problems, network congestion, and other cross-chain failure risks. An optimistic design and liquidity pool do not remove those risks, and a transfer may be delayed or fail.

ACX also carries token-specific risks: governance decisions may not benefit every holder, incentives can change, and market prices can fall sharply. A token held on the wrong network or sent to the wrong address may be unrecoverable. Keep only what you can afford to lose, and test unfamiliar wallet or transfer steps with a small amount when practical.
