Launch

Four fields and a tenth of a cent.

Fixr mints the token, claims a pre-ground address ending in agent, registers your .agent name and hands you the keys.
The launch rail is not live yet. Payment verification and minting are built but have not both been proven on mainnet, and until they have there is no button here that would do anything. The pool and the resolver below are real and running now.

Pool status

pool depth

unknown

the grinder has not reported yet

The grinder is not reporting, so this is genuinely unknown rather than zero. When ready reaches zero a launch has to wait for the grinder, and the wait is measured in minutes rather than seconds — which is the entire reason the pool exists. See the docs for the numbers.

What you send

A launch is one request. The x402 handshake happens first: the endpoint answers an unpaid request with 402 Payment Required and a price, your client pays 0.001 USDC and retries with proof.

  "name":      "Your Project",
  "symbol":    "YOURS",
  "uri":       "https://…/metadata.json",
  "agentName": "yourproject",         // becomes yourproject.agent
  "payer":     "<your wallet>"        // signs, pays rent, becomes creator
}

What comes back

{
  "mint":        "7xKq2mPvR4nT8wLbYc3ZfHjD5sQe1UgA9vagent",
  "name":        "yourproject.agent",
  "secretKey":   "…",      // base58. Shown ONCE. Fixr keeps no copy.
  "transaction": "…",      // base64, already signed by the mint key
  "blockhash":   "…",
  "estimatedCostLamports": "12685000"
}

You sign transaction with your payer wallet and submit it. That is the launch. Fixr never submits it and never holds your SOL.

You pay the network rent — about 0.0127 SOL. That is measured from a real launch, not estimated, and it is the same whoever creates the mint. It is also why Fixr can charge a tenth of a cent: if Fixr paid the rent, every launch would cost it roughly a thousand times its own fee, and a loop could drain the wallet.
The secret key is returned once and never stored. Lose it and it is gone — we cannot resend what we did not keep. It is also your fallback: the blockhash expires in about a minute, and if it does you can rebuild the transaction yourself from this key.

What Fixr does not do

He does not take a share of supply, hold your funds, or buy your token. He does not vet what you launch or have any view on what it is worth. The fee is the fee; there is nothing behind it.
