Plasma RPC Endpoint

Flat-rate Plasma RPC provider and Plasma RPC node access: free tier, no KYC, HTTP & WebSocket. Plasma mainnet chain ID 9745.

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

Plasma Ecosystem

DeFi deployments reported on Plasma include Aave, Ethena, Euler, Fluid, and Pendle, alongside its stablecoin payment infrastructure.

Quick Start: Connect to Plasma

cURL

curl -X POST https://rpc.swiftnodes.io/rpc/plasma?key=YOUR_API_KEY \
  -H "Content-Type: application/json" \
  -d '{"jsonrpc":"2.0","method":"eth_blockNumber","params":[],"id":1}'

ethers.js

import { JsonRpcProvider } from "ethers";

const provider = new JsonRpcProvider(
  "https://rpc.swiftnodes.io/rpc/plasma?key=YOUR_API_KEY"
);

const blockNumber = await provider.getBlockNumber();
console.log("Plasma block:", blockNumber);

viem

import { createPublicClient, http } from "viem";

const client = createPublicClient({
  transport: http("https://rpc.swiftnodes.io/rpc/plasma?key=YOUR_API_KEY"),
});

const blockNumber = await client.getBlockNumber();

web3.py

from web3 import Web3

w3 = Web3(Web3.HTTPProvider("https://rpc.swiftnodes.io/rpc/plasma?key=YOUR_API_KEY"))
print("Plasma block:", w3.eth.block_number)

Plasma guides from the blog

• Plasma RPC: The Chain Where Sending USDT Costs NothingPlasma is a stablecoin-focused EVM L1 (chain ID 9745) with a protocol paymaster that makes basic USDT transfers zero-fee — users don't even need the native token. It's standard EVM (viem/ethers work), with sub-second PlasmaBFT finality and Bitcoin anchoring. Here's the developer map, including how the gasless-stablecoin model changes payment flows.
