NadFun Token Creation

Guide users through uploading an image and metadata, mining a vanity salt, and deploying a token on-chain via BondingCurveRouter in a 4-step flow on Nad.fun.

Nad.fun Token Creation Flow

Prerequisite: monad-development Skill

Before proceeding, check if the monad-development skill is installed. If it is not available, install it using ClawHub:

bash

clawhub search "monad"

Find and install the monad-development skill from the results. This skill is required for wallet management and on-chain actions in Step 3 and Step 4.

Help the user create a token on Nad.fun by following the 4-step sequential process below. Each step depends on the output of the previous step.

API Base URL

Production: https://api.nadapp.net

Contract Addresses

Step 1: Upload Image

POST /agent/token/image

• Content-Type: image/png, image/jpeg, image/webp, or image/svg+xml
• Body: Raw binary image data (max 5MB)
• Returns: image_uri (CDN URL) and is_nsfw (boolean)

js

const imageResponse = await fetch("https://api.nadapp.net/agent/token/image", {
  method: "POST",
  headers: { "Content-Type": imageFile.type },
  body: imageFile,
});
const { image_uri, is_nsfw } = await imageResponse.json();

Error Codes

Status	Description
400	Invalid image format or missing image
413	Image exceeds 5MB limit
500	NSFW check failed or upload failed

---

Step 2: Upload Metadata

POST /agent/token/metadata

• Content-Type: application/json
• Requires: image_uri from Step 1

Request Body

Required fields:

Field	Type	Constraints
image_uri	string	Must be from https://storage.nadapp.net/
name	string	1-32 characters
symbol	string	1-10 characters, alphanumeric only (/^[a-zA-Z0-9]+$/)

Optional fields:

Field	Type	Constraints
description	string or null	Max 500 characters
website	string or null	Must start with https://
twitter	string or null	Must contain x.com and start with https://
telegram	string or null	Must contain t.me and start with https://

js

const metadataResponse = await fetch("https://api.nadapp.net/agent/token/metadata", {
  method: "POST",
  headers: { "Content-Type": "application/json" },
  body: JSON.stringify({
    image_uri,
    name: "My Token",
    symbol: "MTK",
    description: "An awesome token for the Nad.fun",
    website: "https://mytoken.com",
    twitter: "https://x.com/mytoken",
    telegram: "https://t.me/mytoken",
  }),
});
const { metadata_uri } = await metadataResponse.json();

Error Codes

Status	Description
400	NSFW status unknown, invalid data, or validation failed
500	Upload to storage or database failed

---

Step 3: Mine Salt

POST /agent/salt

• Content-Type: application/json
• Requires: metadata_uri from Step 2
• Produces a vanity token address ending in 7777

Request Body

Field	Type	Description
creator	string	Creator's wallet address (EVM format)
name	string	Token name (must match metadata)
symbol	string	Token symbol (must match metadata)
metadata_uri	string	Metadata URI from Step 2

js

const saltResponse = await fetch("https://api.nadapp.net/agent/salt", {
  method: "POST",
  headers: { "Content-Type": "application/json" },
  body: JSON.stringify({
    creator: walletAddress,
    name: "My Token",
    symbol: "MTK",
    metadata_uri: metadataUri,
  }),
});
const { salt, address } = await saltResponse.json();

• Returns: salt (bytes32 hex) and address (token address with 7777 suffix)

Error Codes

Status	Description
400	Invalid parameters
408	Timeout - max iterations reached
500	Internal server error

---

Step 4: Create Token On-Chain

Call BondingCurveRouter.create() with the data from previous steps.

TokenCreationParams

solidity

struct TokenCreationParams {
    string name;
    string symbol;
    string tokenURI;      // metadata_uri from Step 2
    uint256 amountOut;    // 0 for no initial buy, or use Lens.getInitialBuyAmountOut(amountIn)
    bytes32 salt;         // salt from Step 3
    uint8 actionId;       // always 1 (graduate to Capricorn V3)
}

solidity

function create(TokenCreationParams calldata params) external payable returns (address token, address pool);

Option A: Create Without Initial Buy

Send only the deploy fee as msg.value.

js

const curve = new ethers.Contract(BONDING_CURVE_ADDRESS, BONDING_CURVE_ABI, signer);
const [deployFee,,] = await curve.feeConfig();

const params = {
  name, symbol,
  tokenURI: metadata_uri,
  amountOut: 0,
  salt,
  actionId: 1,
};

const tx = await router.create(params, { value: deployFee });
await tx.wait();

Option B: Create With Initial Buy

Send deployFee + amountIn as msg.value. Use Lens.getInitialBuyAmountOut(amountIn) for amountOut.

js

const lens = new ethers.Contract(LENS_ADDRESS, LENS_ABI, signer);
const expectedAmountOut = await lens.getInitialBuyAmountOut(amountIn);

const [deployFee,,] = await curve.feeConfig();

const params = {
  name, symbol,
  tokenURI: metadata_uri,
  amountOut: expectedAmountOut,
  salt,
  actionId: 1,
};

const tx = await router.create(params, { value: deployFee + amountIn });
await tx.wait();

---

Wallet for On-Chain Actions

For Step 3 (salt mining) and Step 4 (on-chain deployment), use the wallet from the monad-development skill. That skill handles all wallet configuration, private key management, and RPC setup. Use the signer and wallet address it provides when calling the salt API (creator field) and when sending the BondingCurveRouter.create() transaction.

---

Important Rules

1. Sequential process - Each step depends on the previous step's output.
2. NSFW validation - Images are auto-checked in Step 1; the flag carries into metadata.
3. URL validation - All URLs must use HTTPS. Twitter must use x.com, Telegram must use t.me.
4. Image domain restriction - Only https://storage.nadapp.net/ image URIs are accepted in metadata.
5. Salt mining - May timeout if the vanity address pattern can't be found within iteration limits.
6. actionId - Always use 1 (graduate to Capricorn V3).

When Generating Code

• Use ethers v6 syntax by default unless the user specifies otherwise.
• Always handle errors for each API call before proceeding to the next step.
• The salt from Step 3 and metadata_uri from Step 2 are both needed for Step 4.
• For initial buy, always query Lens.getInitialBuyAmountOut() to get the correct amountOut.
