Check Mate

Check Mate allows to compose and setup a suite of multiple on-chain transaction checks in your smart contract account.

The Safe (formerly Gnosis Safe) allows to setup a transaction guard that performs some checks before and after the state changes when executing a transaction. Check Mate allows to set up a transaction guard that manages multiple guards, composing and ordering by priority all the on-chain transaction checks that are performed. This adds some benefits to the initial solution: Only devs who can write smart contracts can use a one-guard solution that is customized to fit their needs. Having all the transaction checks in just one guard implies that it has to be updated every time the checked conditions change increasing the risk of introducing new bugs. A modular solution allows to easily add and remove specific checks and build a customized check suite for your smart contract account in a no-code way for the user. Creating small and specific checks as public goods that can be easily reused and composed by the community will increase the adoption of transaction guards, allowing a lot more people to benefit from them.

SignerData

Data-driven growth with onchain profiles.

SignerData: Real-time onchain profiles for dApp growth SignerData provides real-time, on-chain profiles for dApps whenever users log in, offering deep insights into user activity, transaction history, and behavioral patterns. It empowers dApp developers with actionable intelligence, enabling personalized user experiences, targeted notifications, and data-driven product decisions. The SignerData Dashboard delivers a comprehensive overview of dApp usage, presenting key metrics like active users, session counts, and address segmentation. Advanced filtering allows developers to drill down into specific user cohorts, such as whales, frequent traders, or dormant addresses. This enables a more precise understanding of user behavior, including insights like average transaction frequency, long-term retention, and high-value user identification. Backend Built with Node.js, Express, and PostgreSQL, the SignerData API provides real-time profiles for any Ethereum address on login, while simultaneously logging user sessions for detailed analytics. Swagger UI documentation ensures seamless integration for developers. Frontend The frontend, built with Vite and React, acts as a SaaS platform. Users can register, manage subscriptions, and create projects, each with its own dedicated dashboard. As users log into the registered dApp domains, these dashboards populate with real-time data, providing immediate value to developers. The landing page also includes a simple demo for quick profile lookups. Additional context Source: https://x.com/pet3rpan_/status/1919709492679475360
