# txFusion > All-in-one platform for using and building on ZKsync txFusion is a blockchain infrastructure company focused on Zero-Knowledge technology for Ethereum and Bitcoin. It builds the txSync platform, offering tools and SDKs for managing digital assets and developing applications on ZKsync. txFusion is a company that builds Zero-Knowledge infrastructure and developer tooling for the Ethereum and Bitcoin ecosystems. It designs products and provides engineering services that simplify the integration of ZK technology for both end users and development teams. Its work spans asset management interfaces, cross-network bridges, transaction automation, and developer SDKs. The company addresses the complexity of building on ZK rollups by packaging common integration tasks into ready-made tools rather than requiring teams to build them from scratch. Its flagship offering, txSync, is a modular platform for using and building on ZKsync, combining a web portal, a bridge for moving funds between Ethereum and ZKsync, a paymaster configuration tool, and software development kits. txFusion also takes on direct engineering work for other protocols, such as maintaining SDKs and relayer infrastructure on their behalf. txSync groups its offerings into asset management, fund transfers, and paymaster and automation tooling, alongside developer SDKs for integrating ZKsync functionality into third-party projects. The company also explores extending Zero-Knowledge technology to the Bitcoin ecosystem. It serves individual users managing assets on ZKsync as well as development teams and protocols that rely on its tooling and engineering support to operate on ZK rollups. - Type: Company - Sector: Infrastructure - Status: Active - Founded: 2023-10-01 - Profile: https://thegrid.id/profiles/txfusion ## Products - [txPortal](https://thegrid.id/profiles/txfusion): txPortal is the Web interface for viewing and managing digital assets across ZKsync networks. (Wallet, Live, Main Product) - [txBridge](https://thegrid.id/profiles/txfusion): txBridge is a bridge for transferring funds between Ethereum and ZKsync Era. It locks assets on the source network and issues equivalent assets on the destination network, using a rollup-based execution environment to reduce fees and settlement time compared to direct Ethereum transactions. The product is aimed at users and developers who need to move funds between the two networks while retaining Ethereum-level security. (Bridge, Inactive/Support Ended) - [Tsuko](https://thegrid.id/profiles/txfusion): Tsuko is a developer tooling product providing paymaster-as-a-service functionality on ZKsync Era. It lets projects create, customize, and manage paymasters, the smart contracts that cover transaction fees on behalf of end users, without writing custom code. Software development kits extend this functionality, letting developers integrate paymaster support directly into their own applications. Development teams use Tsuko to offer gasless or sponsored transactions within their applications on ZKsync. (Developer Tooling, Live) - [Visor](https://thegrid.id/profiles/txfusion): Visor is a developer tooling product that automates recurring blockchain transactions on ZKsync Era. It is designed to schedule and execute tasks such as paying dividends, managing expenses, or triggering contract interactions on a set schedule, while keeping funds under the user's control. The product is intended for developers and businesses needing recurring on-chain operations without manual intervention. (Developer Tooling, In Development) - [Playground](https://thegrid.id/profiles/txfusion): Playground is a sandbox environment for testing txSync products on ZKsync Era without using mainnet funds. It lets developers and users try features of the portal, bridge, and paymaster tooling in a risk-free setting before committing real assets. The product supports evaluation and learning for those exploring the broader product suite.
