WHAT IT DOES

This tool scans any webpage to detect every address-like string including cryptocurrency addresses (Bitcoin, Ethereum, Solana, and others), IP addresses (IPv4 and IPv6), email addresses, URLs, blockchain transaction hashes, and token IDs. For each address found, it displays the detected type, the full address string with a shortened preview, the element containing it, and surrounding context text. Each address is validated using format-specific rules—Ethereum addresses are validated for length and hexadecimal format, Bitcoin addresses for length and character set, IP addresses for correct octet ranges, and emails for proper domain structure. A powerful search filter lets you find addresses by type (e.g., "Ethereum", "Bitcoin", "IPv4"), by partial address value, or by the containing element. You can copy individual addresses or all detected addresses to your clipboard with one click. The inspector mode lets you click any address-like text on the page to see its detected type, validation status, and surrounding context in a detailed alert dialog.

WHERE IT RUNS

The script runs on every website and web application you visit. It works with plain text content, code blocks, and dynamically rendered content regardless of framework—React, Vue, Angular, Svelte, or plain HTML. It captures addresses rendered server-side or client-side, and accurately identifies them using comprehensive regex patterns.

HOW TO USE

Upon installation, a floating panel appears with the tool interface. Click "Scan" to analyze the current page for all addresses and hashes. Use the search box to filter results by address type (e.g., "Ethereum", "Bitcoin", "IPv4"), by partial address value, or by element selector. Notice that each entry shows a colored type badge, a shortened address preview, and validation status (valid/invalid). Hover over any entry in the panel to highlight that element on the page with a colored outline matching its type. Click "Copy" on any entry to copy the full address to your clipboard. Click "Copy All" to copy all filtered addresses as a newline-separated list. Click "Inspect" to enter inspector mode, then click any address-like text on the page to see a detailed report including its type, full address, validation result, and surrounding context. Click "Inspect" again or press Escape to exit inspector mode.

TECHNICAL MECHANISM: MULTI-PATTERN ADDRESS DETECTION WITH VALIDATION

This tool uses a comprehensive set of regular expressions to detect nine different address types across page content. It employs a two-stage detection process: first, it extracts potential address strings using type-specific regex patterns; second, it validates each match using format-specific validation functions. Ethereum addresses are validated for the 0x prefix and 40-character hexadecimal format with optional checksum validation. Bitcoin addresses are validated for the correct starting character (1 or 3) and length range (25-34 characters) using Base58 character set. Solana addresses are validated for length (32-44 characters) and character set, with exclusion of 0x-prefixed strings. IPv4 addresses are validated by parsing each octet and ensuring values are in the 0-255 range. IPv6 addresses are validated for proper colon-delimited format. Email addresses are validated using the standard RFC-friendly regex pattern. URLs are validated for proper protocol and domain structure. Token IDs are validated as numeric strings, and transaction hashes as 0x-prefixed 64-character hexadecimal strings. The tool processes all text nodes, extracts matches, and deduplicates results by address and type to prevent duplicate entries.

THE PANEL

The panel is fully draggable and remembers its position per website using GM_setValue. It automatically snaps to the nearest screen edge when released for a clean workspace. Click the collapse button to minimize it to a small floating bubble that takes minimal space. Click the bubble to expand the panel back. The panel can be resized by dragging any edge or corner. Press the Escape key to close the panel temporarily, and click the extension icon to reopen it.

PLEASE NOTE

This script requires the free BotGentz extension to function. As websites frequently update their structure and content delivery methods, scripts may need occasional updates to maintain compatibility. All data processing happens locally in your browser—no information about your pages, addresses, or browsing habits is ever transmitted or stored externally. The tool accesses page content solely for the purpose of address detection and analysis, and does not modify or persist any page data. Address detection is based on pattern matching and validation may not catch all edge cases; always verify critical addresses through trusted sources.
