chaintool / DEUTSCH
FAQ
Clear answers about the local-first tools, supported networks and data handling.
Are seed phrases and private keys uploaded?
No. Generation runs in the browser with Web Crypto. chaintool does not provide a server endpoint for seed phrases or private keys.
Can I use generated keys for valuable funds?
Do not treat a normal browser as a hardware security boundary. For material funds, use a reputable hardware wallet and verify its recovery flow offline.
Why does a tool contact an RPC?
Fee Window, Approval Radar and some developer tools need live public chain data. Those requests go directly from your browser to the selected RPC provider.
Which chains are supported?
The seed generator covers common BIP-39-style network recipes. Live tools cover selected EVM networks. Bitcoin is supported in the seed and unit tools; its Signet listing describes a self-hosted Bitcoin Core RPC rather than an EVM endpoint.
Does chaintool connect to my wallet?
No wallet connection is required for the current tools. Never share a recovery phrase with a website, person or support account.
Why are language-specific URLs used?
Each supported language has its own stable URL so visitors, links and search engines can identify the intended language. The language switcher preserves the page where possible.
Can I rely on public RPC endpoints in production?
Public endpoints can be rate-limited or change without notice. Use your own provider and monitoring for production software.
