What you can build

Blockchain capabilities, exposed as simple APIs

Every OneChain product is backed by the same API surface. Call the services you need — no blockchain expertise required.

Documents

Create tamper-proof documents, attach files, sign them on-chain, and retrieve cryptographic proofs of authenticity.

7 endpoints

Digital Assets (NFT)

Mint NFT collections, transfer and trade tokens, and manage base URIs — gas-free on a permissioned chain.

10 endpoints

Products

Register and track products (e.g. timber, recycled materials) with full provenance, pagination, and on-chain transaction IDs.

9 endpoints

IdeaBlock

Upload and timestamp intellectual property or user files, then verify them later by content hash — proof of existence, on demand.

4 endpoints

IPFS Storage

Upload multiple files to decentralised IPFS storage and fetch them back by hash — durable, content-addressed data.
