We formalise routing and arbitrage = on such networks as convex optimisation problems. We provide bounds with cl= osed formulas in the specific case of =93constant product=94 automated mark= ets and a restricted form of cyclic arbitrage. We compute the associated lo= wer bounds on actual data derived from the Ethereum blockchain.
