BitGo Holdings has brought its wallet and custody infrastructure to Arc, a new Layer-1 blockchain built around stablecoin-based financial applications, while Robinhood is preparing to enable USDC transactions on the network. The developments give institutional and retail users additional routes for moving USDC on a blockchain designed specifically for payments, treasury management, and other financial workflows.

According to BitGo, its Arc integration is already operational. Eligible clients can deposit and withdraw USDC through Self-Custody MPC wallets in both hot and cold configurations, Custody MPC wallets, and Go Account, with MPC (multi-party computation) splitting key management so that no single party holds a complete private key. Support for EURC, Circle's euro-denominated stablecoin, is also available.

Arc Is Built Around Stablecoins

Arc was launched by Arc Network Services, a Circle-backed initiative, as an EVM-compatible Layer-1 blockchain focused on stablecoin-based financial activity. Circle is the issuer of both USDC and EURC, meaning the stablecoin at the center of the network comes from the same company backing the network itself. EVM compatibility allows the chain to run Ethereum-style smart contracts, so developers can build with existing Ethereum tooling. The network uses USDC as its native gas asset and is designed to deliver dollar-denominated transaction fees and sub-second finality.

The architecture targets use cases including stablecoin payments, corporate treasury management, tokenized assets, and other programmable financial operations. Using USDC for gas is intended to simplify transaction-cost management for organizations that primarily operate in dollar-denominated assets, since they do not need to acquire and manage a separate native token of the kind most public blockchains require.

BitGo's infrastructure includes indexing for native USDC movements and transfers on Arc. The company has also enabled auto-consolidation and bulk withdrawals, providing tools for clients that manage assets across multiple addresses.

Automated Gas Management

BitGo's Gas Tank covers the gas costs generated through auto-consolidation on Arc. The feature is designed to reduce operational requirements by allowing automated consolidation without clients having to maintain a separate balance reserved for network fees.

The combination of Arc's USDC-based gas model and BitGo's Gas Tank is intended to simplify treasury operations by making transaction costs more predictable and removing the need to manage a separate native gas asset.

BitGo's support spans both institutional custody and self-custody arrangements. Clients can therefore access Arc through established BitGo infrastructure while retaining different levels of control over their digital assets.

Arc is operated through a permissioned validator set. According to the announcement, the network has not been reviewed or approved by the New York State Department of Financial Services or any other regulatory authority.

Robinhood Prepares USDC Support

Robinhood is also preparing to add USDC transactions on Arc. Under the planned integration, the trading platform will allow users to deposit and withdraw USDC directly through the Arc network.

The integration would connect Robinhood's customer base with Arc's stablecoin-focused infrastructure and provide another channel for USDC transfers. Direct deposits and withdrawals could also reduce the number of intermediary steps required when users move USDC between compatible services.

The development is significant because Robinhood's support would extend Arc beyond specialized blockchain infrastructure and into a consumer-facing financial platform. It also gives USDC another potential route for circulation between trading accounts and onchain applications.

The timing reflects the growing role of stablecoins in functions beyond crypto trading, including payments, settlement, and treasury operations. Arc's design targets these use cases, while Robinhood's integration could serve as a bridge between conventional trading interfaces and stablecoin-based blockchain activity.

A Broader Institutional Strategy

BitGo provides custody, wallet, staking, trading, financing, stablecoin, and settlement services. The company also operates BitGo Bank & Trust, a federally chartered digital asset trust bank.

Its Arc integration extends that infrastructure to another blockchain while maintaining support for both self-custody and institutional custody models. The inclusion of indexing, automated consolidation, and bulk withdrawals is intended to address the operational requirements faced by organizations managing larger digital-asset balances.

Together, BitGo's operational support and Robinhood's planned USDC connectivity could broaden access to Arc by pairing institutional custody infrastructure with a consumer-oriented platform for USDC transfers.

Stablecoin Infrastructure Expands

The developments around Arc reflect a broader push to build blockchain infrastructure designed specifically for stablecoin activity. Rather than treating stablecoins solely as trading assets, Arc incorporates USDC throughout its transaction and settlement architecture.

For BitGo clients, the launch provides access to Arc through existing wallet and custody infrastructure. For Robinhood users, the planned USDC integration could offer another route for moving dollar-denominated digital assets between the platform and Arc.

The effectiveness of these integrations will depend on adoption, transaction volumes, liquidity, and the development of applications built on Arc. Regulatory considerations will also remain relevant as stablecoin-based financial infrastructure expands.

The combined rollout nevertheless gives Arc two significant access points at an early stage: Bit's institutional wallet and custody infrastructure, and Robinhood's planned consumer-facing USDC connectivity.
