Blockchain as a Service (BaaS) for Web3 teams. Multi-chain RPC endpoints, AI-powered smart contract IDE, and managed node infrastructure built for reliability, scale, and lower ops overhead.
No RPC calls, no JSON payloads, no infrastructure to configure. Query any EVM chain with a single function call.

}Connect to 30+ chains out of the box. Compatible with every major Web3 library and toolchain.
Write, test, deploy, and monitor — all from one environment. No glue code required.
Integrated development tools for writing, testing, and deploying smart contracts. Built-in compiler, debugger, and deployment pipeline.
Browser-based workspaces with full LSP, integrated terminal, and local chain validators. No local setup required.
Deploy to Solana, Ethereum, Polygon, Base, Arbitrum, Optimism, Avalanche, and BSC from a single pipeline.
Tenant isolation, RBAC with 40+ permissions, full audit trail, and data portability. Built for teams shipping production protocols.
AI layer
Not a third-party plugin. An AI engine that understands your chain, your contracts, and your deployment context — running alongside every request.
Turn a plain-English spec into audited, gas-optimized Solidity in seconds. The AI writes, tests, and security-scans before you see the output.

From intent to production. No local setup, no DevOps, no infrastructure management.
Tell the AI what you want to build in plain language. Specify your target chain, architecture constraints, and security requirements.
kn ai "token vesting contract with 6-month cliff on Solana"The orchestrator routes to specialized agents that plan file structure, dependency graph, security model, and test strategy. You review before anything executes.
kn ai plan --reviewA fully configured workspace boots in under 5 seconds — IDE, local validator, debugger, and AI assistant. Edit, test, and iterate in the browser.
kn workspace create --chain solana --template anchorOne command deploys to devnet, testnet, or mainnet. Gas estimation, verification, and post-deploy checks are handled automatically.
kn deploy --chain solana --network mainnet-betaReal-time dashboards for transaction volume, error rates, and contract health. Alerts, audit logs, and scaling controls built in.
kn monitor --dashboardMost Web3 teams juggle 6+ services just to ship. One platform replaces your entire infrastructure stack.
Production-grade guarantees backed by real infrastructure.
Multi-region redundancy with automatic failover ensures your RPC calls always reach a healthy node. Built for production workloads.
Geo-intelligent routing sends every request to the nearest healthy node. Sub-50ms P50 latency across all 5 regions worldwide.
First-class clients for JavaScript/TypeScript, Python, Go, Java, Ruby, Rust, and .NET. All generated from a shared OpenAPI spec.
Ethereum, Polygon, Arbitrum, Base, Optimism, Solana, Avalanche, BNB Chain, zkSync, Linea, Fantom, Gnosis, Celo, Scroll, and more.
Per-tenant rate limiting, API key scoping, audit trails, and data isolation enforced at the gateway layer. No shared-state leaks.
CLI tools, SDK libraries, and example apps are open source. Inspect the code you depend on — no black boxes.
Your code stays yours, your data stays isolated, and your deploys stay auditable. Here's what that looks like in practice.
Open-source SDKs, CLI, and client libraries. Inspect the code you depend on — no proprietary black boxes.
Every workspace runs in its own container with network policies and resource limits. No shared runtimes.
Every API call, AI action, deployment, and configuration change is logged with actor, timestamp, and diff.
Export everything — code, configs, deployment scripts, CI/CD pipelines — in standard formats. No vendor lock-in.
Run workspaces in US, EU, or APAC. Data residency controls for compliance. Edge-cached static assets.
Comprehensive automated testing across every layer. Every release verified before deployment.
Recent product updates and improvements.
