metsumi-chan docs

metsumi-chan is a community launchpad on Solana. Tokens launch on a Meteora Dynamic Bonding Curve (DBC), are quoted in SOL, priced live by Jupiter, and graduate automatically to a permanent DAMM v2 pool when the curve fills.

How it works

Every launch follows the same on-chain path — no manual migration step:

  1. Bonding curve. A new token opens on a DBC. Buyers trade against the curve, quoted in SOL.
  2. Graduation. When the curve reaches its migration threshold, liquidity moves to a DAMM v2 pool on-chain.
  3. Open trading. From there the token trades like any DAMM v2 pair, fed by Jupiter routing.

metsumi-chan co-signs a freshly generated mint for each launch. Your wallet pays the network rent and signs the transaction — nothing custodial.

Launch a token

Open /launch, connect a Solana wallet, and fill the form:

  • Name & Ticker — the token name and symbol (≤ 10 characters). Must be unique on metsumi-chan.
  • Description — a short blurb shown on the token page.
  • Website & X — optional links surfaced on Discover and the token page.
  • Quote — all launches are quoted in SOL.
  • Initial buy — optional first dev-buy (in SOL) bundled into the same transaction.
  • Logo — an image (≤ 5MB). It is hosted by metsumi-chan and referenced from the token metadata.

What happens on submit

  1. The logo uploads, then the server builds the DBC create transaction and co-signs the mint.
  2. Your wallet signs; the transaction is broadcast and confirmed.
  3. The token is saved and appears on Discover with a page at /token/<mint>.

An optional platform fee (set by the operator) may be charged in SOL and sent to the project treasury.

Vanity addresses

Token mint addresses on metsumi-chan end with MET (for example …SgMET). The server keeps a pre-ground pool of matching keypairs so launches are instant, and a background grinder keeps the pool stocked.

Operators can pre-seed or top up the pool:

node scripts/grind-vanity.mjs --suffix MET --count 10

Discover & trade

Discover lists every token launched on metsumi-chan — logo, description, price, market cap, liquidity and holders — paginated 10 per page, with live data from the Jupiter data API. Each token has its own page with full stats, links, the contract address, and an embedded swap so anyone can buy in a couple of clicks.

Portfolio & fees

The Portfolio page shows the metsumi-chan tokens your connected wallet holds (balance and value), and any fees you can claim — built so you only ever sign with your own wallet; nothing is custodial.

Creator fees (deployers)

Token creators earn a share of trading fees. If you launched a token, your unclaimed fee balance shows next to it with a Claim fees button — it appears only when there is something to claim. The claim transaction is built for your wallet, you sign, and the fees land in your wallet.

Partner & migration fees

The project’s partner wallet (the config feeClaimer) sees an extra Partner earningssection to claim partner trading fees and, for graduated pools, withdraw migration fees. This section is only visible to the partner wallet. Because every launch happens here, the mint and pool addresses are known, so fee balances are read directly from on-chain pool state.

FAQ

Do I need SOL to launch?

Yes — your wallet pays Solana network rent for the new accounts, plus any optional initial buy and platform fee.

Is metsumi-chan custodial?

No. metsumi-chan only co-signs the token mint. Your wallet holds your funds and signs every transaction.

What pool does it graduate to?

A Meteora DAMM v2 pool — liquidity migrates there automatically, on-chain, once the bonding curve fills.

Is this financial advice?

No. metsumi-chan is software for launching and trading tokens. See the Terms and Privacy Policy.
