https://api-plasma-mainnet.n.dwellir.com/<your-api-key>wss://api-plasma-mainnet.n.dwellir.com/<your-api-key>Plasma is an EVM Layer 1 for stablecoin payments. It runs PlasmaBFT consensus and a Reth execution client. Block time is 1 second. You pay gas in XPL. Existing Solidity contracts deploy without changes. Hardhat, Foundry, ethers.js, viem, and MetaMask work as they do on Ethereum. Payment apps and wallets use Plasma for 1 second confirmation and standard Ethereum JSON-RPC.

FAQs
Plasma is an EVM Layer 1 built for stablecoin payments. It runs PlasmaBFT consensus and a Reth execution client. You pay gas in XPL. This is not an Ethereum rollup, and it is not the old Ethereum Plasma design.
Plasma Mainnet Beta uses chain ID 9745. The native token is XPL with 18 decimals. Testnet uses chain ID 9746. Wrapped XPL (WXPL) is 0x6100E367285b01F48D07953803A2d8dCA5D19873.
Yes. You can deploy existing Solidity contracts without changes. Hardhat, Foundry, ethers.js, viem, and MetaMask work. Fees use EIP-1559 and you pay them in XPL.
Add a custom network. Network name Plasma Mainnet Beta. RPC URL https://api-plasma-mainnet.n.dwellir.com/<your-api-key>. Chain ID 9745. Currency XPL. Explorer https://plasmascan.to/.
HTTPS is https://api-plasma-mainnet.n.dwellir.com/<your-api-key>. WebSocket is wss://api-plasma-mainnet.n.dwellir.com/<your-api-key>. Chain ID is 9745. Requests without an API key return 403.
Yes. The same host serves JSON-RPC over WSS, including eth_subscribe for newHeads.
No. Dwellir runs Plasma as full nodes, not archive nodes. Use recent blocks for state reads. Genesis-state eth_call is not guaranteed.
You get standard Ethereum JSON-RPC plus debug and txpool. Trace methods are not available on this endpoint.
Ethereum is a general-purpose L1. Plasma is a separate L1 with PlasmaBFT and Reth, built for stablecoin payments. Bitcoin is a UTXO chain. Plasma is not a Bitcoin L1 and not an Ethereum rollup.
You pay gas in XPL. Custom ERC-20 gas is not live yet.
USDT on Plasma is USDT0 at 0xB8CE59FC3717ada4C02eaDF9682A9e934F625ebb with 6 decimals. Call transfer(to, amount) with a standard EIP-1559 transaction and pay the gas in XPL. A transfer uses about 61,000 gas and the base fee sits around 8 wei, so the fee is a small fraction of a cent. Native USDC is at 0x2d661C89D812261039AF9764eceaAee884f5F67F. Sponsored zero-fee USDT transfers go through Plasma's API-keyed relayer rather than a transaction you broadcast yourself. See the Stablechain RPC guide for the code.
Plasma keeps a conventional EVM gas model, paid in XPL, while Arc uses USDC as gas, Stable uses USDT0 and Tempo takes fees in any USD stablecoin. Plasma produces 1 second blocks with finality two to three blocks later; the other three finalize on inclusion. Dwellir runs all four mainnets. The Stablechain RPC guide lays out chain IDs, endpoints and transfer code for each.
