Somnia RPC Endpoint

Flat-rate Somnia RPC provider and Somnia RPC node access: free tier, no KYC, HTTP & WebSocket. Somnia mainnet chain ID 5031.

Somnia is an EVM-compatible Layer 1 optimised for very high transaction volume with sub-second finality, using a MultiStream consensus design and a purpose-built state database called IceDB.

About Somnia

Somnia was built by Improbable together with the Somnia Foundation and reached mainnet with its SOMI token in September 2025, following a testnet period that processed billions of transactions. The chain markets itself in seven figures of TPS for simple transfers, which matters mainly for applications — games, agent economies, high-frequency consumer apps — where per-transaction cost has to be near zero.

Contracts are standard Solidity against an EVM, so porting is usually a configuration change. SOMI pays gas and secures the network through staking. The engineering trade-off to be aware of is that throughput claims of this size generally assume simple transaction shapes; complex contract calls cost proportionally more, so measure your own workload rather than the headline number.

Common Use Cases on Somnia

• On-chain games
• AI agent transactions
• Consumer social apps
• High-frequency micro-payments
