Immutable Form 1-P rows on Robinhood Chain — hash + metadata, no rewrite.
Filing protocol · Robinhood Chain
EDGAR for memes.Launch starts with a prospectus.
pdf.fun is a registry-first launch layer: attach a PDF, commit its hash onchain, compete in a public queue. Bonding comes later — filings come first.
Catalog
EDGAR-lite feed: queue by upvotes, newest by time, hash-verified PDF viewer.
Signal
Offchain upvotes rank demand. Rank is a signal — never a launch promise.

Step 01 / 05
What is a filing?
A filing is Form 1-P: name, ticker, short thesis, and a PDF prospectus. The content hash is written on Robinhood Chain. The file itself lives on IPFS — permanent commitment, not a rewriteable website.

Today: submit filings, browse the queue, upvote with SIWE. $PDF is the protocol brand — fee sinks (filing → launch → migrate) arrive in later phases. We do not claim buyback is live.
