What is dual-signature minting?

Both the buyer's wallet and your server-side policy wallet must sign the minting transaction. This prevents unauthorized minting while keeping the process trustless for the buyer.

How are private keys stored?

Policy wallet keys are encrypted at rest using AES-256-CBC with your WordPress salt keys. They never leave the server.

Does this support mystery box / random minting?

Yes. You can configure weighted rarity pools and mystery box reveals with configurable odds per trait.

Cardano Minting and Payments Easy is a WordPress plugin that brings full-featured NFT minting directly into your WordPress site. Designed for creators, project teams, and businesses building on Cardano, this plugin lets you launch multi-variant NFT collections with weighted rarity, mystery box blind reveals, and per-wallet mint limits — all managed from your WordPress admin dashboard. Transactions are secured through dual-signature architecture, requiring both the customer’s connected wallet and your encrypted policy wallet to sign every mint, ensuring no unauthorized tokens ever hit the blockchain.

The plugin supports the Cardano NFT standards that matter most: CIP-25 metadata with unlimited custom attributes, CIP-27 royalty tokens that are automatically minted alongside your first NFT in each policy, and CIP-30 wallet connectivity for Eternl, Lace, Vespr, Nami, and other popular Cardano wallets. Policy wallet credentials are protected with AES-256-CBC encryption derived from your WordPress security salts, and seed phrases are displayed only once during generation — giving you full custody without exposing keys in your database. Prices are set in USD and auto-converted to ADA at the time of purchase, removing the guesswork from pricing your drop.

Whether you are running a PFP collection with tiered rarity, a mystery box campaign where artwork stays hidden until reveal, or a whitelist-gated VIP mint with CSV-managed access lists, the workflow is the same: create your collection and variants in the Mint Manager, set quantities and rarity weights, upload artwork or pin images to IPFS through the built-in Pinata integration, and embed the shortcode on any page or post. Per-wallet tracking, mint history exports, and unique minter analytics give you full visibility into your drop’s performance without leaving WordPress.

Built to work alongside CardanoPress for wallet connections and powered by ADA Anvil for transaction building and blockchain submission, this plugin handles the entire minting pipeline — from policy ID generation with time-locked expiration to on-chain metadata formatting and royalty enforcement. It supports both mainnet and preprod testnet environments, so you can validate your complete flow before going live.

Trust Model

Hybrid

This plugin uses a hybrid custody model. The server holds an encrypted policy wallet for co-signing, while the user’s browser wallet provides the second signature. Neither party can act alone.
