Arithmic Network

Arithmic Network is an Ethereum Layer 2 project started in 2023, centered on native staking and restaking through Multichain Staking Pools. Users deposit ETH, BTC, liquid staking tokens, restaking tokens and selected Layer 2 assets into one pool; the differing return rates inside the pool are aggregated, and deposits are staked on Arithmic itself and restaked on EigenLayer up to the deposit cap, with staking and actively validated service rewards distributed pro rata. Execution runs on Soma, a zkVM built on the Lasso and Jolt lookup argument framework, with results posted to Ethereum mainnet as blob transactions.

The project published a technical paper in August 2024 describing a universal Layer 2 with native restaking, and in October 2024 announced a partnership with EigenLayer to extend restaking beyond Ethereum to other Layer 1 and Layer 2 networks while launching its own actively validated service. It is categorized as a modular Layer 2 pivoting on a zkVM and restaking, with discussion focused on whether yield and validation security can hold simultaneously once Bitcoin and Ethereum liquidity share one pool.
