Platform
Build a market from modules that run themselves.
The services your market needs run as smart contracts on one EVM chain: order books and matching, prices and outcomes, automation, settlement and credit. Your venue composes a market instead of operating one.

Live RPC reading
Replace the offchain services you can't audit.
Offchain matching engines, oracles and keepers can't be checked onchain. Somnia runs each of those services as a contract on the same chain that settles the market, so your venue can check every step.
An offchain matching engine (replaced)
Somnia Markets
Order books and matching run as contract code, so the state a venue reads is the state that settles, in the same block.
A separate oracle network (replaced)
Somnia Oracle and Somnia Price Feeds
Outcomes and prices arrive onchain and are read by the same contracts that settle.
Keepers and bots (replaced)
Somnia Reactivity
Handlers run when an event fires, in the same block, so settlement and liquidation never wait on an operator.
Offchain middleware (replaced)
Somnia Agents
Contracts call APIs, read websites and run deterministic AI models as part of consensus, with a signed receipt for every result.
Five layers.Twelve modules.
Each module is a set of contracts on the same chain. Use one on its own, or compose several into a venue.

Blockchain
One chain made of the Global L1 and low-latency Regional Subchains, plus bridging and dedicated RPC access.
02
Markets
Order books, matching and settlement that run as smart contracts, shared by every venue.
03
Data and truth
Prices and real-world outcomes, delivered onchain with provenance.
04
Agents and automation
Consensus-validated compute, AI inference and event-driven contracts built for automated flow.
05
Settlement and liquidity
The stablecoin and credit layer that markets on Somnia settle and borrow against.
One event.Every layer, one block.
When an outcome resolves, the answer, the handler, the settlement and the balance change land together. Nothing waits on an operator in between.

Built to be checked,not taken on trust.
The chain, its execution and the token behind it are reviewed, cross-checked and held by names venues already work with.
Read the audit reportsAudited
The Somnia L1 and its consensus were audited by Hacken. The market contracts carry their own audit.
Shadow-verified execution
Every validator runs Cuthbert, an independent unoptimised implementation, alongside the fast path. Nodes halt on any divergence.
Institutional custody
Somnia and SOMI are supported by custody and wallet providers such as BitGo, Fireblocks and Ledger.
