#Gate广场中秋团圆局 #Gate首日支持ARC公链 September 16 marked the beginning of Arc’s mainnet era, but the more interesting story is what arrived with it. Arc launched with 100+ applications and more than 100 institutional and ecosystem builders, creating a financial-infrastructure ecosystem from day one rather than starting with an empty chain waiting for activity to appear.

The architecture is also designed around a different payment model. USDC is Arc’s native gas asset, meaning users do not need to acquire a separate volatile token simply to pay transaction fees. Arc targets deterministic sub-second finality, which becomes particularly relevant for financial applications where predictable settlement can matter as much as raw transaction speed. This combination puts stablecoin-based settlement directly into the network’s core design.

The institutional composition makes the launch even more notable. Arc’s validator ecosystem includes names such as BlackRock, DTCC, ICE, Mastercard, Standard Chartered, Visa and Worldpay. That does not guarantee adoption, but it does show that Arc is being positioned around institutional and financial use cases from the beginning. The ecosystem already includes major DeFi infrastructure such as Aave, Morpho and Uniswap, alongside tokenized products including BlackRock’s BUIDL and Circle’s USYC.

The strongest evidence that Arc did not simply appear overnight is its testnet history. Before mainnet, the network processed more than 700 million transactions, giving developers and ecosystem participants a substantial testing environment before public launch. For a new financial chain, that pre-mainnet activity is an important metric because early infrastructure reliability can determine whether initial attention turns into sustained usage.

Then there is the Gate day-one access layer. Gate has integrated Arc across Gate Web3, Wallet, market discovery and Trenches, while Trenches provides 0-Gas trading support for Arc assets. Gate has also integrated Uniswap V2, V3 and V4 on Arc, creating multiple liquidity routes for assets entering the ecosystem. This matters because a new chain can have strong technology and still struggle if users cannot easily discover, access and trade its first-wave assets.

But the most interesting development may be outside traditional DeFi. Arc’s Agent Stack introduces policy-controlled wallets and programmable USDC transactions designed for AI-agent finance. That opens a different direction: instead of blockchain activity being driven only by human users interacting with DeFi applications, programmable agents could eventually execute financial actions under predefined rules. The important metric here will not be the narrative itself, but whether real applications generate recurring transaction volume and liquidity.

One distinction around the ARC token is essential. Circle has minted the full 10 billion ARC initial supply, but that does not mean Circle has committed to publicly launching an ARC token. Network fees continue to be paid in USDC. Therefore, ARC should not automatically be treated as a conventional gas-token launch, and ecosystem activity should be evaluated separately from assumptions about future token economics.

For Gate users, the first phase is best viewed as a liquidity discovery period. Instead of chasing the largest first-day price move, the more useful dashboard is 24H trading volume, liquidity depth, holder growth, new-wallet activity, DEX volume, repeat transactions and the number of assets maintaining meaningful liquidity after the initial launch wave.

That creates a simple progression to watch: 100+ applications → early liquidity → active users → recurring transactions → deeper markets. If those stages develop together, Arc’s day-one launch could evolve into a sustainable financial ecosystem. If activity falls sharply after the initial attention, the 700M+ testnet transactions and impressive institutional roster would remain infrastructure achievements rather than proof of lasting economic adoption.

For #Gate首日支持ARC公链, the key story is therefore not simply that Gate arrived on day one. It is that Arc launched with financial institutions, established DeFi protocols, tokenized assets, AI-agent infrastructure and Gate liquidity access already connected to the network. The next signal will come from the data: whether day-one attention turns into day-30 liquidity. @Gate_Square
