Nodit now supports Arc mainnet through Elastic Node and Web3 Data API.
Following our earlier testnet support, this release gives developers access to Arc mainnet RPC endpoints and indexed onchain data. Teams preparing digital asset payment services, stablecoin integrations, and treasury applications can now connect their production workloads to Arc through Nodit.
TL;DR
- Arc mainnet is supported through Nodit Elastic Node and Web3 Data API.
- Arc uses USDC for gas fees and provides deterministic finality in less than a second.
- Connect through HTTPS and WebSocket RPC endpoints, with managed infrastructure that scales within the limits of your selected plan.
- Retrieve indexed onchain data, including balances, transfers, and transaction history, without operating your own indexer.
Meet Arc: A Layer 1 for stablecoin finance
Arc is an open Layer 1 blockchain developed by Circle for stablecoin finance. It is designed for financial applications, including payments, settlement, treasury operations, and foreign exchange.
Gas fees are paid in USDC and priced in dollars, making transaction costs easier to understand and plan for. Arc settles with deterministic finality in under a second, which suits applications that need timely confirmation of settlement. The network is EVM-compatible and connects to Circle services, including CCTP and Paymaster. It runs on a permissioned validator set whose founding cohort includes BlackRock, Mastercard, Visa, NYSE, and Standard Chartered, and more than 100 institutions took part in its testnet.
Node access and indexed data through one provider
Financial applications need both a way to interact with the network and a way to retrieve usable records of onchain activity.
Nodit brings these capabilities together for Arc mainnet. Elastic Node provides RPC access for reading network state and submitting transactions. Web3 Data API provides indexed data for account views, activity tracking, and operational workflows.
Teams can use both products through Nodit to reduce infrastructure maintenance and focus on application development.
Connect to Arc mainnet with Elastic Node
Elastic Node provides managed RPC access so your team can build without deploying and maintaining Arc nodes.
Available capabilities include:
- HTTPS endpoints: Read network state and submit transactions through RPC requests.
- WebSocket connections: Receive network updates through supported subscriptions.
- Capacity that adjusts with usage: Handle changing traffic within the maximum performance of your selected plan.
- Managed node operations: Reduce the infrastructure maintenance required to keep your application connected.
Teams migrating an existing EVM application can use familiar tools while reviewing network settings, contract dependencies, and transaction behavior before production use.
Query Arc data with Web3 Data API
Web3 Data API provides indexed onchain data for application features and operational workflows.
Your team can access:
- Balances: Populate account views and monitor holdings.
- Transfers: Track USDC and other token movements.
- Transaction history: Retrieve account activity for user interfaces and reconciliation.
- Parsed transaction data: Use structured transaction details in application logic and analysis.
These APIs reduce the need to build and operate a separate indexer.
Build payment and treasury workflows on Arc
Nodit combines RPC access and indexed onchain data in one platform. This gives teams the infrastructure to submit transactions, retrieve onchain records, and connect that information to application workflows.
Common use cases include:
- Payments: Submit payment transactions and track their status and associated transfers.
- Settlement reconciliation: Use transfer records and transaction history to compare onchain activity with internal records.
- Treasury monitoring: Track balances and stablecoin movements across relevant addresses.
- Account activity: Display balances, transfers, and transaction history within your application.
