👨💻 Developers

What can a developer build?

1. Token-gated dApps & REST APIs: monetize by making your dApp or its REST API token-gated. Here's how.
2. AI dApps: monetize your AI dApp by token-gating on AI training data, feature vectors, models, or predictions.
3. Data Markets: build a decentralized data market.
4. Private user profile data: storing user profile data on your centralized server exposes you to liability. Instead, have it on-chain encrypted by the user's wallet, and just-in-time decrypt for the app. Video, slides.

Example live dApps

• Acentrik Market - Enterprise data market, by Daimler
• Ocean Predictoor - Token-gated AI prediction feeds
• Autobot - Token-gated analytics on Data Farming
• Ocean Waves - Token-gated music market
• Ocean token-gating - Token-gated content
• Ocean Market - General data market

How do developers start using Ocean?

• Highest-level: Use an Ocean Template.
• Library level: Use ocean.js is a library built for the key environment of dApp developers: JavaScript. Import it & use it your frontend or NodeJS.
• Contracts level: Call Ocean contracts on Eth mainnet and several other chains.
