your launch carries a metadata blob: name, symbol, description, image, optional socials. the platform uploads this to IPFS and pins the CID. that CID becomes part of your token’s NewTokenV6 params on-chain, so it lives forever.

​
fields

  • name the token’s full name. shows in wallets and explorers. e.g. “WAIFU”.
  • symbol the ticker. uppercase, three to six letters typical. e.g. “WAIFU”.
  • description short pitch, one to three paragraphs. shown on the launch page and in the IPFS metadata.
  • image main thumbnail. PNG or JPG. 512x512 minimum, square preferred. the platform uploads to IPFS and includes the image CID in the metadata.
  • banner optional wide image for the launch hero. 1500x500 recommended.
  • twitter / telegram / website optional links. plain URLs.

metadata JSON shape

what the platform pins to IPFS looks like this:
the resulting metadata CID is what goes into the FLAP meta field of NewTokenV6Params. once pinned, it is immutable.

​
practical tips

  • double-check the symbol. wallets show the symbol everywhere. typos are permanent.
  • own the social handles. if your twitter does not exist yet, claim it before the launch goes live. presalers will check.
  • image quality matters. the thumbnail is the first impression. compressed blurry images hurt your launch.
  • description is short and direct. TPOT lowercase works fine. no formatting, no markdown.

​
what you cannot change

once createLaunch() is called, the metadata CID is locked into the launch config. there is no admin function to update it. if you need to change anything material (image, description), you would need to refund the launch and create a new one.

third-party storage notes

waifu.fun pins to its own IPFS gateway. we replicate to public pinning services where possible. if you want belt-and-suspenders durability, you can pin the same CID to your own pinata or filebase account. CIDs are content-addressed, so the same content always produces the same CID.

​
image guidelines

  • format PNG or JPG
  • size up to 5 MB
  • aspect ratio square for the thumbnail, 3:1 for the banner
  • no embedded fonts or metadata you do not want public
