What is the Plasma RPC URL?

The Plasma Mainnet RPC URL with BoltRPC is https://endpoints.boltrpc.io/rpc/YOUR_API_KEY/plasma. Replace YOUR_API_KEY with your API key from dashboard.boltrpc.io. The chain ID is 9745.

How do I add Plasma to MetaMask?

Open MetaMask, go to Settings, then Networks, then Add Network, and enter: Network Name: BoltRPC Plasma, RPC URL: https://endpoints.boltrpc.io/rpc/YOUR_API_KEY/plasma, Chain ID: 9745, Currency Symbol: XPL.

Is Plasma EVM compatible?

Yes. Plasma runs a standard EVM execution layer. Solidity contracts deploy without modification and the usual tooling works out of the box. Only the RPC URL and Chain ID (9745) change.

What gas token does Plasma use?

XPL is the native gas token. For simple stablecoin transfers the protocol can sponsor gas; contract interactions pay gas in XPL as usual.

Does BoltRPC provide Plasma archive access?

Yes. BoltRPC serves Plasma with full archive access since genesis: historical balances, contract state and debug traces at any block.

Does BoltRPC support WebSocket for Plasma?

Yes. BoltRPC provides WebSocket endpoints for Plasma at wss://endpoints.boltrpc.io/ws/YOUR_API_KEY/plasma. Use WebSocket for real-time streaming: new blocks, pending transactions, Transfer events.

Connect your dApp, bot, or payment backend to Plasma Mainnet with BoltRPC. Plasma is the EVM chain built around stablecoins as the primary asset, and predictable request-unit pricing keeps your RPC costs as stable as the dollars moving through your contracts.

What Plasma is Built For

Plasma starts from a simple observation: most real blockchain volume is dollars, so it builds the chain around them. It is a purpose-built EVM Layer 1 where stablecoins are the first-class asset: simple USDT transfers can run with sponsored gas so end users do not need to hold the native token, while the XPL token powers the chain’s own economics. Under the hood it pairs a fast BFT consensus (sub-second finality) with a standard EVM execution layer, so Solidity contracts, ethers.js, viem, Foundry and Hardhat all work unchanged. Launched in late 2025, it has drawn payment processors, neobank-style apps and stablecoin DeFi. Payment infrastructure is exactly the workload where RPC reliability is customer-visible: deposit detection, balance polling and transfer confirmation run continuously, and a throttled public endpoint shows up as a stuck checkout.

Common Use Cases on Plasma

Stablecoin payments and payouts Payment processors confirm dollar transfers in near real time. Their backends poll receipts and stream Transfer events continuously: sustained read traffic that scales with users, not with speculation.

Deposit detection for wallets and merchants Merchant tools and custodial wallets watch addresses for incoming stablecoins. An eth_getLogs pipeline over one-second blocks needs a provider that sustains continuous reads without gaps.

Stablecoin DeFi Lending, FX and yield around native dollars run the classic DeFi pattern: continuous eth_call polling against rates and positions, with WebSocket streams for liquidations.

Accounting and compliance Balance-at-date reports and transfer history exports are archive workloads. Full archive on the standard endpoint means no second provider for historical queries.

Built for teams that ship on Plasma.

Full archive access included

BoltRPC serves Plasma with full historical state since genesis, measured live against our own nodes. Transaction history, balance-at-date reporting and compliance exports work without a separate archive provider.

Debug methods included

The full debug_* family is available on Plasma (traceTransaction, traceBlock, traceCall and more), so you can replay any transfer or contract call without running your own node.

Built for payment backends

Deposit detection and transfer confirmation are continuous, latency-sensitive workloads. A dedicated endpoint keeps eth_getLogs scans and receipt polling fast at any transaction volume.

WebSocket streaming included

Subscribe to new blocks and Transfer events over WebSocket at no extra charge. Payment services credit deposits the moment they land instead of a polling interval later.

EVM compatibility, zero migration friction

Plasma is fully EVM compatible. Contracts, scripts and infrastructure written for Ethereum work unchanged: switch the RPC URL, set Chain ID 9745, and you are live.

Full JSON-RPC coverage.

Every standard Plasma method you would expect. Archive-only methods are available on request for qualifying plans.
