This simple browser-based messaging application illustrates how to integrate TACo's encrypt/decrypt API and predicate access to private data on prespecified on-chain conditions – all while storing the encrypted data on ComposeDB.
Note that this demo is based on a fork of ceramicstudio’s lit-composedb repo, with the TACo library replacing LIT. This demonstrates that developers who have already integrated LIT’s permissioned service can easily substitute it for TACo’s decentralized access control plugin.
This demo requires:
- A Metamask wallet with Polygon Amoy testnet added, and multiple accounts to mimic a real-world decryption flow.
- A positive balance of Polygon Amoy testnet tokens (> 0.00 MATIC) held in one of the accounts, in order to satisfy the default access conditions.
- Node
v16running in your terminal.
- Install your dependencies:
npm install- Generate your admin seed, admin did, and ComposeDB configuration file:
npm run generate- Run your application (for subsequent runs, only this step is required):
npm run devThe application will run on http://localhost:3000.
