# Keep Network > Keep Network is a privacy-focused blockchain infrastructure project that merged with NuCypher to form the Threshold Network. Its flagship product is tBTC, a decentralized, trust-minimized bridge that tokenizes Bitcoin (as the TBTC ERC-20 token) for use in Ethereum DeFi without centralized custodians. The developer surface is on-chain smart contracts plus first-party JavaScript/TypeScript libraries — there is no hosted REST API. ## About - Keep Network / Threshold Network: https://keep.network - Successor network (Threshold): https://threshold.network - tBTC dashboard: https://dashboard.threshold.network/tBTC - Blog: https://blog.keep.network ## Code and SDKs - GitHub organization (106 repos): https://github.com/keep-network - tBTC v2 (Solidity contracts): https://www.npmjs.com/package/@keep-network/tbtc-v2 - tBTC v2 TypeScript SDK: https://www.npmjs.com/package/@keep-network/tbtc-v2.ts - tbtc.js (JavaScript bindings): https://www.npmjs.com/package/@keep-network/tbtc.js - keep-core contracts: https://www.npmjs.com/package/@keep-network/keep-core - ECDSA wallet contracts: https://www.npmjs.com/package/@keep-network/ecdsa - Random Beacon contracts: https://www.npmjs.com/package/@keep-network/random-beacon - All @keep-network npm packages: https://www.npmjs.com/org/keep-network ## Security - security.txt: https://keep.network/.well-known/security.txt - Security policy: https://github.com/threshold-network/solidity-contracts/blob/main/SECURITY.md - Disclosed vulnerabilities: https://threshold.network/disclosed-vulnerabilities - Security contact: security@threshold.network ## Community - Discord: https://discord.gg/Threshold - X / Twitter: https://twitter.com/keep_project
