🛠️ What to Build

The short answer: anything on-chain using Tatum.

If your project uses Tatum APIs, MCP server, or our infra to connect with a blockchain, it qualifies.

Here are some ideas to spark inspiration:

• Wallets & Dashboards – build tools to track balances, transactions, and insights (Data insights)
• DeFi Bots & Automations – trading, arbitrage, compliance, or risk monitoring flows ( Satoshi Wallet Tracker or Malicious Address Check)
• NFT Apps – marketplaces, minting tools, reveal schedulers, or creative drop mechanics
• Explorers & Analytics Tools – surface indexed blockchain data in user-friendly ways
• Creative Experiments – games, bots, or automations that make on-chain data fun and useful
• AI + Blockchain– try our MCP server to let agents interact with blockchains.

You can even build your own MCP using ours as a base, or contribute new features through a pull request in our

open-source repo
