Portus

Portus is an intent-solver protocol in the Ethereum ecosystem, aimed at users who want better execution prices on chain. It takes a user's intent (for example, selling an asset within a price range) rather than a fixed transaction path and hands it to an open solver network that competes to deliver the optimal fill, drawing on batch auctions and intent-filling designs of CoW-style protocols.

The protocol addresses high slippage, fragmented routing and MEV erosion in decentralized trading: by consolidating orders and running a competitive auction, solvers find the best cross-pool execution and return savings to users. Its narrative positions it as intent-execution infrastructure. Since launch, cumulative intent volume processed by the protocol has reached roughly 11 billion US dollars, reflecting growing demand for verifiable best execution.
