Plasma RPC Endpoints & API

Plasma is a Layer 1 blockchain purpose-built for global stablecoin payments. It combines high throughput, stablecoin-native features, and full EVM compatibility, giving developers the foundational infrastructure to build next-generation payment and financial applications.

Developers can deploy applications and protocols using the tools they already use, including Hardhat, Foundry, and wallets like MetaMask. Plasma also provides protocol-maintained contracts for zero fee USD₮ transfers, custom gas tokens, and confidential payments. These features are scoped for stablecoin use cases and integrate cleanly with EIP-4337 and EIP-7702 smart accounts. While not yet embedded at the protocol level, they are designed for deeper coordination with block building and execution over time.

Whether a developer is building anything from a wallet to an FX system or a consumer application, Plasma gives them the speed, liquidity, and flexibility to operate at global scale.

Plasma RPC Endpoints on OnFinality

OnFinality provides managed Plasma RPC endpoints for developers who need reliable access to the Plasma network without running their own node. Our infrastructure supports both HTTP and WebSocket transports, and offers archive and trace capabilities for deep blockchain data queries.

Key Features

• EVM JSON-RPC: Full compatibility with Ethereum tooling and libraries.
• Archive & Trace Access: Query historical state and debug transactions.
• Global Infrastructure: Endpoints served from multiple regions for low latency.
• Scalable Plans: From shared endpoints to dedicated nodes for high-volume workloads.

How to Connect

1. Create or sign in to your OnFinality account.
2. Select Plasma from the supported networks list.
3. Create an API endpoint (shared or dedicated).
4. Test with eth_blockNumber.
5. Monitor usage and move critical traffic to production.

Why Use OnFinality for Plasma RPC?

Public Plasma RPC endpoints are rate-limited and unsuitable for production. OnFinality provides authenticated access with clearer limits, request analytics, and a path to higher capacity. Whether you're building a wallet, a DeFi protocol, or a backend service, OnFinality gives you the reliability you need.

Plasma RPC and developer resources

Plasma 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 Plasma RPC/API access for dApps, wallets, DeFi, and backend services.
• HTTP and WebSocket support for app, backend, and integration workflows.
• Archive access for historical state, analytics, or compliance-style queries.
• Trace support for debugging transactions and deeper execution analysis.

Decision notes:

• Environment: mainnet. Protocol family: EVM JSON-RPC.
• HTTP and WebSocket support is listed for supported app and backend workflows.
• Archive support is available for historical state or older chain-data queries.
• Trace support is available for transaction debugging and execution analysis.

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.
