ERC-404

The ERC-404 is a hybrid token standard that combines the functionalities of the ERC-721 standard (non-fungible tokens) and the ERC-20 standard (fungible tokens).

---

Endpoints

The Xyxyx API provides ERC-404 functionality through dedicated endpoints, categorized into two subsections, which are based on Xyxyx's two foundational tokenization models:

• Deploy Contract 1x1

• Deploy Contract A4

Each subsection contains specific API endpoints tailored for deploying and interacting with ERC-404 smart contracts using the respective tokenization model.

Endpoint Structure

All ERC-404 endpoints follow the format:

/api/v1/ERC404/{network}/deploy-contract-{model}

Where:

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

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

Example Endpoints

• Deploy an ERC-404 contract using the 1x1 tokenization model on the Ethereum Mainnet:

  /api/v1/ERC404/mainnet/deploy-contract-1x1

• Deploy an ERC-404 contract using the A4 tokenization model on the Ethereum Sepolia:

  /api/v1/ERC404/sepolia/deploy-contract-A4
