Aptos RPC Endpoints & API

Build on Aptos with OnFinality RPC

Aptos is a Layer 1 blockchain built with the Move programming language, designed for high throughput, low latency, and developer-friendly smart contracts. As the network grows, developers need reliable RPC endpoints to connect dApps, wallets, DeFi protocols, and backend services to the Aptos blockchain.

OnFinality provides managed Aptos RPC endpoints and API access, so you can focus on building without worrying about node operations.

What is an Aptos RPC Endpoint?

An Aptos RPC endpoint is a network URL that applications use to read blockchain data, submit transactions, and interact with smart contracts. It acts as the gateway between your application and the Aptos network.

Why Use OnFinality for Aptos RPC?

• Managed Infrastructure: No need to run your own Aptos node. OnFinality handles uptime, scaling, and maintenance.
• Archive Access: Query historical state data for analytics, audits, and backfills.
• Request Analytics: Monitor usage, errors, and limits through the OnFinality dashboard.
• Scalable Plans: From shared endpoints to higher-capacity options as your project grows.

Key Features

• Network: Aptos Mainnet
• Protocol: EVM JSON-RPC (compatible with Ethereum tooling)
• Transport: HTTP
• Advanced Access: Archive support available
• Common Use Cases: dApps, wallets, DeFi, analytics, games, bots, backend services

How to Connect to Aptos with OnFinality

1. Create or sign in to your OnFinality account.
2. Select Aptos from the supported networks list.
3. Create an API endpoint (or deploy a dedicated node if needed).
4. Test the endpoint using eth_blockNumber or other methods.
5. Monitor request usage and limits before moving production traffic.

When to Use Private RPC vs Public RPC

Public Aptos RPC endpoints are fine for lightweight testing. For production workloads, authenticated endpoints provide stable access, clearer rate limits, request analytics, and support for higher traffic.

Aptos RPC for Production Apps

Yes, Aptos RPC via OnFinality is suitable for production applications when the endpoint plan, limits, and monitoring match your workload. Teams building on Aptos trust OnFinality for reliable infrastructure.

Aptos RPC and developer resources

Aptos RPC access is useful when a product needs dependable chain reads, transaction submission, and a clear path from a first request to production infrastructure.

Best fit: mainnet production workflows for dApps, wallets, DeFi, and backend services.

What builders usually check first:

• Read current chain state for apps, dashboards, wallets, and backend services.
• Submit transactions and monitor confirmations from Ethereum-compatible tools.
• Query logs, receipts, and historical state when indexers or analytics pipelines need more than the latest block.
• Debug contract behaviour with trace data where the network supports it.

Supported capability notes:

• Authenticated Aptos RPC/API access for dApps, wallets, DeFi, and backend services.
• Reliable HTTP access for app, backend, and integration workflows.
• Archive access for historical state, analytics, or compliance-style queries.

Decision notes:

• Environment: mainnet. Protocol family: EVM JSON-RPC.
• Reliable HTTP access is listed for supported app and backend workflows.
• Archive support is available for historical state or older chain-data queries.

A quick connection check usually starts with eth_blockNumber, then moves into the exact methods your wallet, dashboard, bot, indexer, or backend service needs.

Planning the next step:

• Shared RPC is a practical starting point for integration, prototypes, dashboards, and many app backends.
• If your product becomes traffic-heavy or operationally sensitive, review the available upgrade path before relying on a single access pattern.
