Free Plasma RPC Endpoint

Plasma is a stablecoin-first L1 with instant, irreversible PlasmaBFT finality and a standout native feature: zero-fee USD₮ transfers via protocol-level paymasters. It runs a standard reth EVM under the hood, so every Ethereum tool works without modification. Very few independent RPC providers serve Plasma yet — NodeFlare runs a dedicated node with multi-region routing and automatic failover.

Plasma RPC URLs#

Public endpoint — no API key:

https://rpc.nodeflare.app/plasma/public

Keyed endpoint (free account — higher limits, heavy methods):

Quick start#

curl https://rpc.nodeflare.app/plasma/public \
  -X POST \
  -H "Content-Type: application/json" \
  -d '{"jsonrpc":"2.0","method":"eth_blockNumber","params":[],"id":1}'

import { ethers } from 'ethers';

const provider = new ethers.JsonRpcProvider(
  'https://rpc.nodeflare.app/plasma/public'
);
console.log('Plasma block:', await provider.getBlockNumber());

from web3 import Web3

w3 = Web3(Web3.HTTPProvider('https://rpc.nodeflare.app/plasma/public'))
print('Plasma block:', w3.eth.block_number)

Plasma at a glance#

Two things make Plasma unusual among EVM chains:

1. Gasless stablecoin transfers. USD₮ transfers are sponsored at the protocol level — users pay zero XPL gas. This is a native primitive, not a relayer workaround. If you’re indexing transfers, expect to see transactions with zero gas cost in receipts.
2. Instant finality. PlasmaBFT consensus makes every accepted block final — the chain never reorgs. A receipt means the state change is permanent; you don’t need confirmation-count logic.

Our per-method reference for Plasma covers chain-specific notes for every JSON-RPC method.

FAQ#

What is the Plasma RPC URL?
https://rpc.nodeflare.app/plasma/public — no API key required, rate-limited per IP. A free key unlocks higher limits, eth_getLogs, and debug/trace methods.

Is the Plasma RPC free?
Yes. The public endpoint is free without sign-up; a free account adds 2M CU/month and a dedicated keyed path with no credit card required.

Does eth_getLogs work on Plasma?
Yes — with a free API key. Transfer-event density is high (stablecoin payments are Plasma’s core use case): use address + topic0 filters. Each call costs 75 CU.

Does Plasma have WebSocket support?
Not yet on NodeFlare — WebSocket is live on Ethereum, Base, BNB Chain, Arbitrum, Optimism, HyperEVM, and Avalanche. Plasma WS is on the roadmap.

Do debug_ and trace_ methods work?
Yes — Plasma runs reth, which exposes the full debug_ and trace_ namespace. These work on the free tier with a key.
