# Integration & Development **Q: How quickly can we integrate Wallets-as-a-Service (WaaS)?**\ A: Our WaaS stack is designed as a "Black Box" implementation. Using our SDKs (iOS, Android, React Native), a developer can generate non-custodial wallets for users in under 15 minutes. We handle the complexity of sharding, storage, and cryptography; you simply make API calls to createWallet or signTransaction. **Q: Which blockchains does Keystone support?**\ A: We are chain-agnostic. Because MPC works at the cryptographic curve level (ECDSA and EdDSA), we natively support over 100+ blockchains (Bitcoin, Ethereum, Solana, Avalanche, Sui, Aptos, etc.). Furthermore, our Raw Signing API allows you to interact with any new chain or custom network immediately, without waiting for an official integration update. --- # Agent Instructions: Querying This Documentation If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.
