Common

Common is a privacy-focused DeFi suite on Aleph Zero, assembled from an AMM, shielded pools, and a bridge: once assets enter a shielded pool the link to the original address is cut, and withdrawing to a new address breaks on-chain tracing, with zero-knowledge proofs verified locally on the device so latency stays close to ordinary transactions. Amounts and identities stay hidden until execution through batched transactions and an MPC-based decryption oracle that exposes only aggregated values, mitigating front-running, with proof generation and verification costs shared between the client and the node network.

Pricing uses a Curve-style StableSwap curve for stable pairs to cut slippage and Dutch auctions to pull in external liquidity, with market making and swapping inside one account system. The product spans Ethereum, Base, Arbitrum, and Aleph Zero across mobile and web clients, with swaps and bridging sharing a single privacy channel, and pool composition and fee parameters adjusted by governance votes.
