Anchorage Digital announced on September 16, 2026 that it is a Day 1 launch partner for Arc mainnet, saying the same institutional-grade custody that its existing clients already use is now available on the Arc network. The announcement positions Anchorage as part of Arc’s launch-stage ecosystem, though 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
Anchorage Digital made the announcement directly on X, describing itself as a founding participant in Arc’s mainnet debut. The company said institutional custody is available on Arc from day one, framing the offering as an extension of services already in use by its institutional clients rather than a new or untested product.

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 partnering 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, which the project says makes costs predictable for institutional participants.
Arc is also EVM-compatible, allowing developers to deploy Ethereum-based smart contracts on the network, and offers opt-in configurable privacy. The network’s stablecoin-native structure makes USDC a central part of its design. USDC was quoted at $0.999692 at the time of the announcement, with a market capitalization of approximately $73.6 billion.
Arc’s official ecosystem directory lists 99 organizations as part of its network, including BitGo, which is described there as offering trading, financing, collateral management, and settlement services. Anchorage’s Day 1 custody claim is distinct from BitGo’s listed role, which does not include that same launch-day custody characterization.
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. The crypto Fear & Greed Index 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.
