nullsink: anonymous LLM proxy

Nullsink is a privacy-focused service that lets you mint anonymous gift cards using Monero (XMR) or Bitcoin (BTC). The service allows you to either enter an existing key to check its balance or leave the key field blank to generate a fresh key directly in your browser. Gift card amounts range from a minimum of $2 to a maximum of $100, with quick-select options of $10, $25, $50, and $100. Payments are processed privately on-chain, with confirmations typically taking 20-45 minutes. The service applies a ~10% markup on top of the credit amount (e.g., a $10.00 credit costs approximately $11.00).
