Protocol Toolkit

Auxiliary Tools for Nostr Creators

Decentralized protocols deserve master-class tooling. Analyze Bech32 parameters, backup lists, validate identities, find pristine relays, and run client simulations directly on the web.

Live Playgrounds & Sandbox Consoles

Perform instant operations with our built-in offline Nostr simulators. Secure and client-side processing guaranteed.

Bech32 Live Converter

Tool Sandbox

Input any structured Nostr string starting with npub, nsec, or note to instantly trace its hex value and checksum validity.

Target Key / Input String

Interactive Prefix Miner

Client Simulation

Estimate calculations for customized addresses. Enter your target prefix below to simulate client-side generation statistics.

Desired Prefix

Mining Speed (H/s)

Contact List (Kind 3) Visualizer

Visualizer

Paste a typical Nostr event tags JSON array (kind 3 contacts block containing list array pointers) to parse it into an auditable follow grid.

Tags Array JSON Input

NIP-05 Handle Verifier

DNS Resolution

Query /.well-known/nostr.json for any internet identifier (e.g. bob@example.com) to verify its mapped public key and relay pointers.

NIP-05 Identifier

NIP-13 Nonce & PoW Verifier

SHA-256 Audit

Audit any raw Nostr event JSON or 64-character hex Event ID to inspect committed nonce tags and measure leading zero-bit Proof-of-Work difficulty.
