Get a Temporary Phone Number for Alchemy
Alchemy is one of the most widely used blockchain development platforms, powering thousands of decentralized applications across Ethereum, Polygon, Arbitrum, Optimism, Solana, and more. As a next-generation Web3 infrastructure provider, Alchemy enables developers to build scalable, reliable, and high-performance blockchain applications without running their own nodes.
With a suite of tools including enhanced APIs, real-time WebSockets, NFT endpoints, debugging dashboards, analytics, rate monitoring, and developer-friendly SDKs, Alchemy simplifies blockchain development for wallets, marketplaces, DeFi protocols, gaming apps, data indexers, enterprise solutions, and experimental projects. Its robust infrastructure powers millions of daily requests with high availability, making it essential for Web3 builders seeking stability and efficiency.
Because Alchemy grants access to high-value API keys, developer accounts, billing dashboards, organization settings, and sensitive project data, the platform enforces strong security practices. One of these measures is phone number verification. This helps prevent unauthorized access, API abuse, spam account creation, and malicious bot activity.
