Mini Contract.Pro

🔥🔥🔥 As a free open-source product with independent intellectual property rights, Mini Contract Pro has always adhered to the principle of "making digital contract development simpler". Mini Contract.Pro is also an open-source electronic signature solution designed specifically for developers, innovatively adopting a "dual-mode engine" architecture. Through modular design, it meets the full-scenario requirements from judicial-level signing to lightweight collaboration. The first open-source electronic signature platform to support both evidence chain and non-evidence chain dual modes, we have helped 100+ enterprise customers achieve digital transformation of contract signing processes. #### Dual-Mode Engine (Flexibly Address Business Scenarios) **Judicial-Level Evidence Chain Mode** Based on the Ant Judicial Chain blockchain evidence storage system, it generates an evidence storage report including timestamps and digital fingerprints for each contract, ensuring contracts comply with the requirements of the "Electronic Signature Law". This mode has been certified by the National Industrial Information Security Development Research Center and is particularly suitable for high-value scenarios such as financial lending, human resources contracts, and intellectual property agreements, with evidence query response speeds reaching millisecond level. **Lightweight Non-Evidence Chain Mode** Adopting self-developed distributed storage technology, it reduces interface call costs by 60% through intelligent routing algorithms. Developers can implement full lifecycle contract management without connecting to third-party evidence storage institutions. It is particularly suitable for high-frequency scenarios such as internal approvals, supplier reconciliations, and quick signing, with a capacity to handle tens of millions of signing requests per day. #### Developer-Friendly **Plug-and-Play Toolkit** * Electronic signature/seal cloud hosting service * Multi-party contract collaborative editing (supports 50+ signing parties operating in parallel) * Intelligent riding seal generation engine (pixel-level positioning accuracy) * Full-channel signing pages (Web/H5/Mini Program/APP multi-platform adaptive) **Deep Open Capabilities** * Provides SDKs in multiple languages including Java/Python/Go * Opens rich API interfaces ### Why Choose Mini Contract Pro? **All-in-One Integration Solution** We integrate mainstream electronic contract service providers in the market (including but not limited to Fadada, e-SignBao, Junziqian, etc.), providing standardized API integration solutions. Developers don't need to integrate with different vendors individually; they can quickly access multiple services through a unified interface, saving more than 90% of integration time. The pre-configured vendor qualification certification system can help you quickly pass compliance audits. **Cost Optimization Advantage** Through the scale effect of centralized procurement, we provide developers with more favorable interface prices than official channels (average discount of 15%-30%). Supports vendor combination selection on demand, avoiding single vendor lock-in risks, truly achieving controllable costs. **Enterprise-Level Technical Architecture** Built on Vue3 + TypeScript + Pinia, adopting: - Modular design: Supports on-demand loading of service provider functions - Responsive layout: Perfectly adapts to PC/mobile dual platforms - Configuration-based development: 90% of common requirements can be implemented through configuration - Complete type support: Comprehensive TS type definitions and interface documentation **Rapid Implementation Capability (Providing Out-of-the-Box Solution)** - Standardized UI component library: Contains 30+ business-validated contract template components (MIT license for commercial use) - Full-link monitoring: Full-process tracking and evidence storage from contract creation to archiving ### Commercial Licensing 1. The commercial version is identical to the open-source version in code, with no distinction; 2. Commercial licensing is perpetual, supporting permanent upgrades; 3. Commercial use requires authorization, and you can contact the technical team below for the authorization method. ### Open Source Notice 1. Only allowed for personal learning and research use; 2. Prohibited from selling this open-source code and resources in any form or name. ### Business Scenarios * **Human Resources Companies:** Frequently signing contracts, high cost of paper contracts, batch contract signing business scenarios * **Financial Companies:** Complete contract signing online, retain timely and effective contract management * **Market Sales Companies:** When selling products through online sales, need to quickly reach cooperation and immediately sign contracts * **Rental Companies:** Need to quickly sign contracts for offline rental companies, online contract management, inquiry, and automatic contract expiration reminders Directory Structure ----------------------------------- ```json mini-contract-pro/ ├── App.uvue // Application configuration, global
