Who should sell on the Datalab

Portex welcomes a spectrum of contributors including but not limited to:

• Individuals & researchers with curated or hard‑to‑reproduce datasets.

• Startups & apps with product data, marketplace logs, or unique user‑generated data (properly aggregated/anonymized as applicable).

• Enterprises with premium alternative/industry-specific data or panels.

• DAOs & dePIN protocols monetizing usage, governance, or ecosystem-collected data.

1) Prerequisites

• Account created and seller access enabled (request if needed).

• Rights & provenance: you can attest that you have the rights to license the data under PSDLA.

• Payout setup: recipient address (EVM wallet) for USDC disbursements.

• Data readiness: schema documented; data quality checked and details articulated.

2) Prepare your dataset

• Format: Tabular → Parquet; multi‑file/multimodal → compressed gz archive file.

• Data Card: include motivation, composition, schema notes, QA metrics (coverage/missingness/de-dupe), update cadence, known limits, and intended/out‑of‑scope uses.

Example structure of a dataset card:

Motivation:
Intended uses / Out of scope:
Provenance & collection method:
Schema & field notes:
Quality (coverage %, missingness, dedup):
Update cadence & versioning:
Known limitations & ethics:

3) Choose a license (PSDLA)

Pick the PSDLA variant that matches your goal:

• NE (Non‑Exclusive) — maximize reach; multiple buyers.

• EX (Exclusive) — sell exclusivity at a premium to one buyer.

• Field‑limited — allow use only within defined domains.

• RS (Revenue Share) — align upside with buyer usage.

Rule of thumb Volume strategy → NE. Strategic partnership → EX. Regulated/sensitive verticals → Field‑limited. Co‑monetization → RS.

4) Price & pick a listing type

• Buy Now: you set a fixed price for immediate purchase.

• Sealed‑Bid Auction: discover market price; buyers submit best offers until expiration.

• Hybrid (Buy Now + Bidding): capture urgency while keeping price discovery open.

Pricing tips

• Start with Hybrid if unsure; tighten to Buy Now once value is clear.

• Use recent update cadence and quality signals to justify higher pricing.

• Consider exclusive licenses for strategic or scarce datasets.

5) Publish your listing

• Upload the dataset files or link to an external dataset.

• Fill in title, summary, long description (with Data Card), tags, and category.

• Select PSDLA variant, listing type, price/bid window, and recipient address.

• Review & publish; verify the listing page renders correctly.

6) Promote, answer Q&A, and update

• Promote: share the listing URL in your channels (site, forum, social).

• Q&A: reply to buyer questions quickly; clarify fields, recency, and license.

• Update cadence: publish new versions on a predictable schedule and note changes in the changelog.

7) Get paid

• Proceeds are paid to your recipient wallet in USDC after a successful sale.

• Keep internal records: listing URL, PSDLA, price, and version purchased.

Responding to buyer demand (RFPs)

If buyers need something bespoke, reply to RFPs with a brief proposal: scope, delivery timeline, PSDLA variant, and price.
