U.S. cryptocurrency exchange Coinbase has announced the addition of support for the Optimism (OP) token.

美國加密貨幣交易所Coinbase宣布增加對樂觀（OP）令牌的支持。

Optimism is a layer-2 scaling solution for the Ethereum blockchain. It uses optimistic rollups to bundle together multiple off-chain transactions, which are then executed on-chain in a single batch. This allows for faster and cheaper transactions than on-chain.

樂觀是以太坊區塊鏈的2層縮放解決方案。它使用樂觀的匯總將多個離鏈交易捆綁在一起，然後將其在單批方鏈上執行。這允許比鏈上更快，更便宜的交易。

Optimism is one of the most popular layer-2 scaling solutions, and it has been used by a wide range of decentralized finance (DeFi) applications. The platform’s native token, OP, launched in May 2023. It is used for governance and staking on the Optimism blockchain.

樂觀是最受歡迎的第2層縮放解決方案之一，並且已通過多種分散融資（DEFI）應用程序使用。該平台的本地令牌OP於2023年5月推出。它用於治理和占用樂觀區塊鏈。

“We are excited to announce that Optimism (OP) is now available on Coinbase One,” the exchange wrote in a statement.

交易所在一份聲明中寫道：“我們很高興地宣布，Coinbase One現在可以使用樂觀情緒（OP）。”

“One members in the U.S. can trade Optimism (OP) with zero trading fees, and enjoy reduced withdrawal fees. We are also offering a limited-time bonus of 1 OP to new members who sign up today and use the code OPBLOCKS.”

“美國的一位成員可以以零交易費用交易樂觀（OP），並享受撤回費的減少。我們還向今天註冊並使用代碼Opblocks的新成員提供了1 OP的限時獎金。”

In addition to zero trading fees and reduced withdrawal fees, Coinbase One members will also enjoy priority customer support and exclusive access to new products and features.

除了零交易費和降低費用降低外，Coinbase One成員還將享受優先的客戶支持以及對新產品和功能的獨家訪問。

To become a Coinbase One member, users must pay a monthly subscription fee of $15. No minimum trade size is required for trading with zero fees.
