Eco’s New Sauce Developer Kit Keeps AI Agents’ Transactions Within Operator-Set Limits

Stablecoin infrastructure company Eco on Wednesday launched Sauce SDK , a toolkit that gives outside developers access to the transaction engine it already runs behind its own Routes API. With Sauce, a developer attaches conditions to a single onchain transaction, such as a minimum amount received , a price limit , a list of approved destinations or a trading algorithm. If the transaction cannot satisfy all of them when it runs, it does not execute and no funds move. The logic is written in TypeScript and checked against live market data inside the transaction itself, so developers do not have to write and deploy a custom smart contract for each use.
