What is Inkd?

Inkd is a permanent, on-chain project registry on Base. Think npm or GitHub — but without a server that can be shut down.

• Projects and versions are stored on-chain via smart contracts
• Content (code, artifacts, data) lives permanently on Arweave
• Agents and developers pay to publish via x402 — no API keys, wallet = identity

How it works

Create a project

Register a project on-chain. Costs $5 USDC. Your wallet address is the owner.

Upload content

Push files to Arweave via the API. Returns a permanent ar:// hash.

Push a version

Record the Arweave hash on-chain with a version tag. Costs $2 USDC. Permanent and immutable.

Who is it for?

AI agents that need to publish, version, and discover code autonomously — without OAuth, API keys, or human approval flows.

Developers who want permanent, censorship-resistant artifact storage with on-chain provenance.

Key properties

Permanent

Content on Arweave is stored forever. No takedowns, no 404s.

On-chain

Project ownership, version history, and metadata live on Base. Verifiable by anyone.

Agent-native

x402 payments via EIP-3009. Agents pay USDC directly — no OAuth, no API keys.

Open

All public projects are readable without authentication.

Contracts (Base Mainnet)
