d4ta docs

Build on the network.

d4ta combines wallet-authenticated users, distributed Qwen inference, browser/native GPU workers, an OpenAI-compatible API and an EVM reward layer on blockchain.

DOCS

Wallet login

MetaMask connects to Robinhood Chain (chain 4663), signs an EIP-4361-style login message, and receives an HttpOnly d4ta session. Signing costs no gas.

DOCS

Browser worker

Visit /earn. Qwen3.5 loads through WebLLM/WebGPU, attempts 9B first and falls back to 4B. The worker is tied to the signed wallet.

DOCS

API

Create a wallet-linked key in Dashboard, then call `/api/v1/chat/completions`. API callers use network GPUs; they do not need to contribute their own.

DOCS

$D4TA contract

The repo includes an ERC-20 on blockchain with a fixed 3% transfer tax. 1.5% routes to a user Merkle vault and 1.5% to a contributor Merkle vault.

DOCS

Reward epochs

Completed user jobs and worker jobs accumulate separate reward weights. `npm run build:reward-epoch` builds a Merkle allocation; `npm run publish:reward-epoch` publishes it on-chain and stores wallet proofs for the claim UI.
