Ronin RPC Endpoint

Flat-rate Ronin RPC provider and Ronin RPC node access: free tier, no KYC, HTTP. Ronin mainnet chain ID 2020.

Ronin is the gaming chain created by Sky Mavis, the studio behind Axie Infinity. Originally an EVM sidechain, it migrated to an OP Stack Ethereum layer 2 in May 2026, using EigenDA for data availability and keeping RON as its gas token.

About Ronin

Sky Mavis launched Ronin in February 2021 as an EVM-compatible sidechain for Axie Infinity, secured by its own validator set. On May 12, 2026 it migrated to the OP Stack and now settles to Ethereum as an optimium, posting transaction data to EigenDA rather than Ethereum blobs. The migration also cut RON emissions sharply.

Chain ID 2020 and RON as the gas token carried over, so existing contracts and wallets continue to work, and developers now get OP Stack RPC behavior and tooling. The ecosystem remains focused on games and NFTs, including Axie Infinity and Pixels.

Common Use Cases on Ronin

• Web3 games such as Axie Infinity and Pixels
• NFT marketplaces and trading
• In-game asset transfers
• RON-based DeFi
