Plasma RPC Endpoint

Fast, flat-rate Plasma RPC node provider — free tier, no KYC, HTTP & WebSocket.

Plasma is a stablecoin-focused EVM Layer 1 built for high-volume stablecoin payments, with a paymaster model that allows zero-fee USDT transfers and gas payable in stablecoins. SwiftNodes provides Plasma mainnet RPC over HTTP and WebSocket.

About Plasma

Plasma's mainnet beta went live on September 25, 2025. It runs PlasmaBFT, a Byzantine-fault-tolerant consensus designed to deliver sub-second block times and fast finality, and periodically anchors state to Bitcoin.

Plasma is EVM-compatible, so standard Solidity contracts and Ethereum tooling deploy without changes. A protocol paymaster sponsors basic USDT transfers so users need not hold the native XPL token, while more complex transactions can pay gas in stablecoins. Details on a newer chain like this can change; check official Plasma documentation for current parameters.

Common Use Cases on Plasma

• Stablecoin payments and transfers
• Zero-fee USDT transfers
• Stablecoin-denominated DeFi
• Cross-border settlement
• Merchant and remittance flows
