Compressed NFT Example Code

Compressed NFT Example Code is a public TypeScript repository demonstrating Solana state compression and workflows for creating, retrieving and transferring compressed NFTs. Its examples use hashes to fingerprint off-chain data and store those fingerprints in an on-chain Concurrent Merkle Tree.

Practical overview

When it fits

Use it when you want concrete TypeScript examples of Solana compressed NFT workflows and can configure a local Node.js, Yarn and RPC environment.

Who it is for

  • Solana developers learning or prototyping compressed NFT workflows.
  • Developers exploring state compression, NFT asset lookups, proof verification or transfers.

Documented uses

  • Create a Merkle tree and NFT collection, then mint compressed NFTs.
  • Fetch compressed NFT assets by owner or collection.
  • Study proof retrieval, client-side verification and compressed NFT transfer flows.
  • Explore Metaplex SDK examples for reading, minting and transferring compressed NFTs.
Before you choose

Requirements & limits

The repository is public. Its README specifies a local Node.js and Yarn setup and a supporting RPC provider URL; no pricing information is provided.

  • The documented stack is TypeScript, Node.js and Yarn.
  • A supporting RPC provider’s cluster URL is required in the setup instructions.
  • Some examples depend on data saved by earlier scripts, making the recommended sequence important.
  • Metaplex SDK examples require an existing tree and collection for the documented mint-to-collection workflow.
  • The repository’s illustrative one-million-NFT cost comparison is an estimate in the README, not a current cost quote.

Check current requirements in the official documentation. Source-based guidance does not mean OpenViST has run or independently tested this project.

Source-based practical guide

Set up the repository for local exploration

Prepare the documented local environment and RPC configuration for the included examples.

Before you start

  • Node.js
  • Yarn
  • A supporting RPC provider’s cluster URL
  • For the documented local-wallet configuration, the Solana CLI and a local testing-wallet keypair JSON file

Steps

  1. Clone the repository and install its packages with yarn install.

  2. Rename example.env to .env.

  3. Set RPC_URL to the cluster URL of a supporting RPC provider.

  4. If using the Solana CLI, set LOCAL_PAYER_JSON_ABSPATH to the absolute path of the local testing-wallet keypair JSON file.

Expected outcome

The repository is configured for the documented script workflow.

Guide limitations

  • This covers setup only; it does not establish that a script was executed successfully.
  • The README recommends running verbose create-and-mint, owner lookup, and transfer scripts in that order because earlier steps save data in .local_keys for later scripts.
