The token
Every token created on Launch uses the same contract: a plain ERC-20 with nothing hidden in it.
The contract
Section titled “The contract”- Standard ERC-20 with 18 decimals.
- Fixed supply of 1,000,000,000, minted once at creation.
- No owner. Nobody can mint more, burn others’ tokens, add a tax, or pause transfers. There are no transfer hooks.
Names and tickers
Section titled “Names and tickers”| Field | Rule |
|---|---|
| Name | 1 to 32 bytes |
| Ticker | 2 to 6 characters, A to Z and 0 to 9 |
The ticker rule matches Hyperliquid’s spot token names, so any Colysium ticker is a valid Hyperliquid spot name.
Image and links
Section titled “Image and links”A token’s image, description and links are stored off-chain, and the token contract points to them:
- The metadata is pinned to IPFS, and the token returns its address from
contractURI(), the ERC-7572 standard that explorers and trading terminals read. - The image is served from Colysium for fast display and pinned to IPFS. The image’s hash is recorded at creation, so anyone can check that the file has not been swapped.
- No uploaded file is stored on-chain. A token without an image shows a pattern generated from its address.
- Images only. Video is not supported.
This record holds confirmed rules only. Contract addresses appear after deployment and verification.
