# Security TokenTraxx data is stored on Arweave, which makes it completely immutable and transparent. Uploaded to the Arweave protocol, every digital collectible and its metadata is stored for at least 200 years. TokenTraxx does not store sensitive information and data on centralised databases i.e., data is secured on stable, matured, and scalable chains like Ethereum, Polygon and Zilliqa. TokenTraxx backend system & app is hosted on AWS cloud that automatically ensures infrastructure security. In addition, to further protect its backend system & app, TokenTraxx is adding a layer of third-party infrastructure management (e.g. Cloudflare). Finally, working with industry-leading smart contract auditors and custodians enables TokenTraxx to ensure enterprise-grade security for its smart contracts, systems, and assets. --- # 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.
