NFT Tools
Build metadata, explore ABIs, calculate rarity, plan deployments. Tools for Ethereum NFT creators and developers.
NFT Metadata Generator
Build ERC-721/ERC-1155 metadata JSON with OpenSea standard support. Add traits, export files, generate batches.
Contract ABI Explorer
Parse and explore smart contract ABIs. Detect ERC standards, view function signatures, and get selectors.
IPFS Hash Converter
Convert between IPFS CID formats (v0/v1) and gateway URLs. Batch process multiple hashes.
On-Chain SVG Builder
Create fully on-chain SVG NFTs. Generate Base64 data URIs for images and metadata. Estimate gas costs.
Rarity Calculator
Calculate NFT rarity scores using statistical methods. Analyze trait distributions and rank your collection.
Royalty Calculator
Calculate EIP-2981 royalties, model revenue projections, and compare marketplace implementations.
Token URI Tester
Test and validate NFT token URIs. Resolve IPFS/HTTP/data URIs, preview metadata and media.
Collection Deployer Planner
Plan your NFT collection deployment. Choose options, estimate costs, get a step-by-step guide.
About Ethereum NFTs
Ethereum NFTs use standards like ERC-721 (unique tokens) and ERC-1155 (multi-token). Modern collections often use ERC-6551 token-bound accounts, on-chain metadata, and deploy to L2s like Base and Arbitrum for lower costs.
These tools help you create metadata, explore smart contracts, calculate rarity, estimate royalties, and plan deployments — all client-side, no data leaves your browser.
