Anchorage Digital announced on September 16, 2026 that it has joined the Arcnet launch as a Day 1 partner, stating that the same institutional-grade custody already used by its clients is now available on the Arc network. The announcement positions Anchorage within Arc's launch-stage ecosystem, although the full scope of the partnership has not been independently confirmed beyond the company's public statement.

What Anchorage Digital Said About the Arc Mainnet Launch

The company disclosed the news directly on X, where it described itself as a founding participant in Arc's mainnet debut. According to the announcement, institutional custody is available on Arc from day one. Anchorage framed the offering as an extension of services its institutional clients already use, rather than a new or untested product. In this context, custody refers to holding digital assets on behalf of institutional clients — a service layer distinct from trading or settlement.

Anchorage describes itself as the home of the first federally chartered digital asset bank in the United States. That regulatory standing is part of what the company implies when it refers to “institutional-grade” custody, though the Arc announcement does not disclose any new regulatory approval or filing tied specifically to Arc support. Anchorage has previously extended its custody services to other networks, including a partnership with Bybit for bbSOL custody on Solana.

Arc Mainnet: What the Network Is

Arc describes itself as an open Layer-1 blockchain built for global markets and real-time value movement. Its design uses stablecoins as gas, meaning transaction fees are paid in dollar-pegged assets rather than a native volatile token. The project says this structure makes costs predictable for institutional participants.

The network is also EVM-compatible, allowing developers to deploy Ethereum-based smart contracts, and it offers opt-in configurable privacy. Arc's stablecoin-native design makes USDC a central component of the system. That design is also what places a custodian inside Arc's institutional picture: the assets held on a client's behalf and the assets used to pay fees belong to the same category of dollar-pegged tokens. At the time of the announcement, USDC was quoted at $0.999692, with a market capitalization of approximately $73.6 billion, according to CoinGecko data.

Arc's official ecosystem directory lists 99 organizations as part of the network, including BitGo, which is described there as offering trading, financing, collateral management, and settlement services. Anchorage's Day 1 custody claim stands apart from BitGo's listed role, which does not include the same launch-day custody characterization. That distinction highlights how ecosystem listings and Day 1 launch designations describe different levels of involvement.

Why the Day 1 Designation Matters, and What Remains Unconfirmed

A Day 1 partner designation signals that Anchorage plans to be operational on Arc from the moment the network goes live, rather than joining after an initial testing or onboarding period. For institutional clients evaluating whether to use Arc, having a federally chartered custodian available at launch reduces one practical barrier to entry. Anchorage has pursued a similar early-entry strategy on other chains, most recently with native swaps in Porto on Robinhood Chain.

The announcement comes against a backdrop of broader institutional activity in stablecoin infrastructure. Western Union recently announced a USD stablecoin on Solana, reflecting growing corporate interest in dollar-based blockchain settlement. Anchorage's Day 1 role adds a custody provider to that expanding layer of institutional stablecoin infrastructure. The crypto Fear & Greed Index, a widely watched sentiment gauge, stood at 51 (Neutral) at the time of the announcement, suggesting the market is not in a strongly risk-on or risk-off position.

What remains unconfirmed is the specific scope of Anchorage's role on Arc: which assets will be supported under custody, when client-facing access will be available, and what onboarding requirements apply. The company's post does not provide those details, and no independent reporting had corroborated the operational specifics at the time of publication. Readers should watch Arc's official launch communications for additional confirmation of partner terms and service availability.
