Circle’s Arc blockchain remains in public testnet, with its Beta mainnet still expected in the summer of 2026, even as more than 300 projects begin building around the network and scammers attempt to exploit confusion about its launch status.
Data from ArcLens shows 308 initiatives already listed in the Arc ecosystem, with early activity concentrated in NFTs, launchpads, meme tokens, decentralized trading tools, payments, privacy infrastructure and stablecoin-focused applications. Circle has also funded eight payment infrastructure teams through its Developer Grant Program, underscoring Arc’s early positioning as a network built around stablecoin settlement and cross-border payments rather than speculative trading alone.
The most immediate message for traders and users is caution: Arc is not yet live on mainnet. Ecosystem contributors have warned about fraudulent websites claiming to offer an “ARC Bridge” and inviting people to transfer USDC. Official explorer data confirms that Arc remains in testnet, and there is no public mainnet bridge available.
The warning is important because transfers involving Circle’s Cross-Chain Transfer Protocol, or CCTP, depend on a burn-and-mint process. If a user sends USDC through an unauthorized or fake bridge, the funds may be unrecoverable. Official launch updates are expected to come only through verified Circle and Arc communication channels.
Arc remains in testnet as builder activity grows
Arc is being developed as Circle’s native blockchain for stablecoin finance, with USDC expected to play a central role in payments and settlement across the network. While the chain has drawn strong early attention from app developers, the project is still in a testing phase.
The Beta mainnet is expected in the summer of 2026. Until then, participation is limited to the official testnet environment, where developers can experiment with applications, infrastructure and transaction flows without treating the network as a fully operational public financial system.
ArcLens data shows a broad mix of projects preparing for the chain’s launch. Many are still early-stage, and some are community-driven experiments. Others are building payment, compliance, identity, trading or data tools intended to support more practical uses once mainnet opens.
The current testnet has already processed more than 244 million actions, according to figures cited by ecosystem participants. That level of activity suggests developers are actively testing contract deployments, transaction routing, wallet connections and application interfaces before real-value activity begins.
Still, testnet activity should not be confused with mainnet readiness. Test networks are designed to expose bugs, test throughput and allow developers to experiment. They do not provide the same guarantees as a live production environment.
Payment grants target emerging markets
Circle’s Developer Grant Program has backed eight payment infrastructure teams, with a strong focus on emerging markets and cross-border settlement. These teams are working on services that use stablecoins to move value across regions where local currencies, banking access and remittance costs can create friction.
Blockradar is one of the larger grant-backed teams by reported activity. The company says it has handled $950 million in payments across 18,200 wallets and 973,000 transactions. Its work focuses on payment infrastructure that can support stablecoin transfers at scale.
Hurupay, which is rebranding to Kolan, reports more than 50,000 active users in over 50 countries. The team says it has processed more than $100 million in payments. Its growth points to a wider trend among payment startups exploring stablecoins for faster and cheaper cross-border transfers.
Myaza is focused on African markets and supports 21 African currencies. The company reports 25,000 registered users and a monthly growth rate of 23%. Its model reflects one of the most closely watched use cases for stablecoins: moving between local currencies and dollar-denominated digital assets in regions with fragmented payment systems.
Arrel Technology’s Omni-Checkout system manages $180 million in annual payments, according to the figures provided. The product is designed as a checkout infrastructure layer, suggesting Arc builders are not only targeting on-chain traders but also merchants and payment processors.
Payrit facilitates $1.9 million across 36,000 cross-border transactions using USDC settlement. ViFi Labs is testing a decentralized foreign exchange protocol for local currencies, including the Nigerian naira and Brazilian real. SFx Money has expanded its user base from 300 to 8,800 over 19 months, while Flezpay’s AI-driven QR payment system operates across 1,613 retail stores and reports monthly recurring revenue above $31,000.
Taken together, the grant-backed teams show that early Arc development is heavily tied to practical payment rails. That focus could help distinguish the network from earlier blockchain launches that leaned mainly on token trading and speculative applications.
Traditional finance and crypto infrastructure join the ecosystem
The Arc ecosystem page lists more than 100 verified partners across traditional finance and digital asset infrastructure. The names include major financial institutions such as BlackRock, Goldman Sachs, HSBC, Deutsche Bank and Mastercard, along with blockchain platforms and protocols such as Aave, Chainlink, Curve and MetaMask.
Their roles vary. Some partners may contribute financial services expertise, while others offer data, wallet connectivity, liquidity tooling, decentralized finance infrastructure or developer integrations. The presence of traditional finance firms is especially notable because stablecoin settlement increasingly overlaps with banking, payments, treasury management and tokenized assets.
For Circle, Arc appears to be part of a broader push to build infrastructure around regulated digital dollars. USDC is already widely used across blockchain networks, but a dedicated chain could allow Circle and its partners to optimize around settlement, fees, compliance features and application development.
That does not mean adoption is guaranteed. Public blockchains often attract large partner lists before launch, but usage after mainnet depends on liquidity, reliability, developer retention, wallet support, regulatory clarity and real demand from businesses and consumers. Arc’s testnet period will likely be watched as a proving ground for those factors.
Trading and launchpad projects prepare for mainnet
Decentralized exchange and launchpad projects are among the most visible categories in the Arc testnet ecosystem. TowerExchange currently leads the stablecoin DEX segment within Arc’s early listings and was previously featured in the Builder Spotlight program.
Radar DEX, previously known as ArcDEXScan, aggregates liquidity data from several protocols and offers a token issuance feature. That makes it both a market data tool and a launch venue for new assets, although its real impact will depend on mainnet liquidity and user demand once Arc goes live.
AstraPump and Lunex are also building experimental trading experiences aimed at stablecoin and meme token communities. These projects reflect a familiar pattern in new blockchain ecosystems: trading venues, launchpads and community tokens often arrive early because they can quickly attract attention and test network activity.
However, the presence of launchpads and meme tokens also raises familiar risks. New token environments can become targets for phishing, fake contracts, copied websites and short-lived projects. Traders using Arc’s public testnet should remember that a live mainnet deployment has not yet occurred, and any site claiming otherwise should be treated with skepticism.
Privacy, identity and NFT projects expand the early map
Arc’s testnet is also drawing privacy and infrastructure builders. Hinkal Protocol has launched on the testnet and is offering encrypted transaction tools. Privacy features are increasingly relevant for businesses that may want blockchain settlement without exposing every commercial detail to the public.
In the NFT category, Orixa is developing the ORIXIANS collection. Arc_Punks and ArcPunksNFT are planning open minting once the mainnet becomes available. ArcCitizens is taking a different approach by focusing on identity-based on-chain NFTs through an open whitelist process.
These NFT projects show that Arc’s early builder base is not limited to payments. Still, their long-term value will depend on whether communities remain active beyond testnet and whether NFT use cases connect with identity, access, loyalty or digital membership rather than only short-term minting activity.
Meme-driven initiatives are also part of the ecosystem. CatBatHatFatRat, for example, is engaging its community through online tools such as profile picture generators and ranking systems. These projects can help drive social attention, but the most durable growth for Arc is likely to depend on deeper financial and payment use cases.
Fraud warnings intensify before launch
The clearest near-term risk around Arc is not technical competition but user confusion. Fraudulent websites have already appeared, including one calling itself “ARC Bridge” and falsely claiming that the mainnet is live.
The warning matters because bridge scams are among the most damaging forms of crypto fraud. A fake bridge can ask users to connect wallets, approve spending permissions or transfer tokens to addresses controlled by attackers. Once a transaction is signed and settled on-chain, reversal is generally impossible.
Community developer Panchu has said a preliminary internal chain is operating under chain ID 5042 and has produced more than 10.4 million blocks. However, that chain is not public. Its existence does not mean the public Arc mainnet has launched.
The distinction is important. Internal chains are often used by development teams to test performance, deployment processes and validator operations before public rollout. They are not open environments for users to bridge funds or trade assets.
Because CCTP transfers require asset burning on one chain and minting on another, fake transfer flows can be especially dangerous. If the burn side or mint side is not connected to an authorized system, users may lose funds permanently.
Market backdrop remains mixed
Arc’s growth comes during a period of strong interest in stablecoin infrastructure from major financial firms and payment companies. A private token sale in May reportedly raised $222 million and valued the network at $3 billion, adding to expectations that large financial players see long-term value in digital dollar rails.
At the same time, market sentiment has not been one-directional. Tarbert recently addressed a sharp stock decline of 76%, with the price falling to $62 by mid-July. The comments reflected the pressure facing companies tied to digital assets, even as stablecoin infrastructure continues to attract strategic attention.
That contrast is central to Arc’s current position. The project has drawn builders, payment startups and major institutional names, but it is still pre-mainnet. Its real performance will only become clear after live deployment, when applications must compete for liquidity, users, transaction volume and business adoption.
For now, the safest path for traders and users is to treat Arc as a testnet-only environment. Real USDC should not be sent to unofficial bridges, and any claim that the mainnet is live should be checked against verified Circle and Arc channels.
Arc’s early ecosystem suggests meaningful demand for stablecoin-native infrastructure, especially in payments and emerging markets. But until the Beta mainnet arrives, the project remains in preparation mode, with opportunity and risk developing side by side.
