ERC-721F

The ERC-721F standard is a variant of the ERC-721 standard conceived by Xyxyx.

ERC-721F is designed to provide highly customizable token issuance by assigning each token an individualized SVG output (svgString) at the time of minting.

Endpoints

The Xyxyx API provides dedicated ERC-721F endpoints that allow developers to deploy contracts and mint text-based tokens dynamically using Xyxyx's two foundational tokenization models:

Deployment & Minting Process

  1. Deploy an ERC-721F contract using the API’s deployment endpoints.

  2. Mint tokens by calling the mint-token endpoint, specifying:

    • The recipient address

    • The token ID

    • The custom SVG (svgString) to be used for the text-based token

Endpoint Structure

All ERC-721F endpoints follow the format:

/api/v1/ERC721F/{network}/{action}{model}

Where:

  • {network} is the target blockchain (e.g., mainnet, sepolia, optimism, etc.).

  • {action} defines the specific operation (e.g., deploy-contract, mint-nft).

  • {model} is either 1x1 or A4, depending on the tokenization model used.

Example Endpoints

  • Deploy an ERC-721F contract on Ethereum Mainnet:

    /api/v1/ERC721F/mainnet/deploy-contract

  • Mint a token using the 1x1 model on Arbitrum:

    /api/v1/ERC721F/arbitrum/mint-nft-1x1

  • Mint a token using the A4 model on Base Sepolia Testnet:

    /api/v1/ERC721F/base-sepolia/mint-nft-A4

Constructor Arguments

The ERC-721F contract supports constructor arguments to customize contract behavior at deployment:

Argument
Description
Example Value

name

Defines the token's name

Token Name

ticker

Defines the token's ticker

TN

supply

Defines the max supply. If set to 0, the collection has infinite supply.

0 or e.g., 10000

mintPrice

Determines the minting cost per token. If set to 0, the minting is free.

0 or e.g., 0.05 ETH

restrictToOwner

If set to true, only the contract owner can mint tokens. If false, minting is public.

true or false
