Okyline is an Executable Data Design (EDD) platform focused on executable validation contracts and operational data quality control.
Rather than managing separate specifications, validation code, tests, and monitoring dashboards, Okyline centralizes validation and quality supervision around a single readable executable contract acting as the operational reference for enterprise data flows.
The same contract powers deterministic validation, advanced business invariant checks, multi-format execution, data quality gates, and historical quality analytics across APIs, events, files, LLM structured outputs, and distributed operational systems.
Contracts are designed directly from annotated sample data, making validation rules immediately understandable for developers, architects, QA teams, and business analysts.
The Community Edition includes the public specification, a free Java runtime engine, a Claude AI assistant for contract generation, and an online studio supporting executable JSON validation contracts and JSON Schema transpilation.
The Enterprise Edition adds native validation for JSONL, XML, CSV, FIXED, and EDI flows together with operational quality dashboards and data quality gates, without requiring databases or centralized infrastructure.erprise Edition supports direct validation of JSON, JSONL, XML, CSV, FIXED, and EDI flows with operational quality dashboards and analytics, without databases.

ContractSafe is AI-enabled contract management software that actually does what it promises, without the six-month implementation, per-seat charges, or admin overhead that makes most CLM tools their own kind of problem.
If you've been through that cycle before (a tool that takes months to deploy, requires a dedicated admin, hides pricing behind a sales call, and still leaves contracts expiring without warning), ContractSafe is the way out.
Search is Google-fast across every contract and attachment, including full OCR on scanned PDFs. The AI assistant automatically extracts key metadata, categorizes contracts by type, and answers plain-language questions about contract content. Smart Search understands your intent rather than requiring exact keywords. None of it needs configuration or a dedicated admin. It works out of the box.
Pricing is published publicly. No "contact sales for a quote," no per-seat charges that penalize you for adding users, no implementation fees. Every plan includes unlimited users, automated renewal and key-date alerts, a dedicated Customer Success Manager, and free onboarding assistance. Higher-tier plans add approval workflows, redlining, and built-in e-signature.
Security: hosted on AWS, SOC 2 Type II and ISO 27001 certified, HIPAA and GDPR compliant, with data residency options across the US, Canada, EU, and Australia.
Most teams are fully operational within hours of signing up. Free trial, no credit card required.

Shiden
Shiden Network operates as a multi-chain decentralized application layer built on the Kusama Network. Since the Kusama Relaychain inherently lacks support for smart contracts, there arises a necessity for a dedicated smart contract layer, which Shiden Network effectively fulfills. From its inception, Shiden has been compatible with the Ethereum Virtual Machine, WebAssembly, and Layer2 solutions, allowing for extensive versatility. The platform facilitates a range of applications, including DeFi, NFTs, and beyond. Token holders of SDN are granted the opportunity to stake their tokens on preferred decentralized applications, enabling both nominators and developers to earn SDN tokens. For those looking to deploy Solidity smart contracts, there are two primary methods available for compilation: utilizing Ethereum tools or employing Solang, a compiler that translates Solidity into WASM. Upon successfully compiling your contract, you are then able to deploy it on the testnet known as Dusty Network, which serves as an excellent environment for testing and development. This flexibility and range of options contribute to Shiden Network's appeal in the broader blockchain ecosystem.

Clarinet
Clarinet offers a command-line interface package that incorporates a Clarity runtime, a Read-Eval-Print Loop (REPL), and a testing framework. Additionally, it provides a JavaScript library, a testing environment, and a web-based Sandbox for development. By using Clarinet, developers can thoroughly test and refine their smart contracts in a local setting prior to deploying them into the live environment. The Clarity programming language enables the development of smart contracts on the Bitcoin network, focusing on security and predictability. It is specifically crafted to ensure that developers can create intricate smart contracts with confidence, as it is tailored for scenarios where errors are unacceptable. This makes Clarity an essential tool for creating reliable and robust blockchain applications.
