Define and Mint Fungible Tokens


The CoCreate API provides functionality for ERC-20 contract deployment & management, including creating new ERC-20 contracts, minting, transferring, and managing token transfer restrictions.

ERC-20 Model

The CoCreate API uses a model that includes the following attributes:

  • name: The name of the ERC-20 contract.
  • symbol: The symbol of the ERC-20 contract.
  • contract_address: The contract address of the ERC-20 contract on the Polygon blockchain.


The CoCreate API provides the following methods for managing ERC-20:

  • Create ERC-20: Create and deploy a new ERC-20 contract
  • List ERC-20: Get a list of all ERC-20 contracts for an organization.
  • Mint ERC-20: Mint ERC-20 tokens to a specified wallet address.
  • Transfer ERC-20: Transfer ERC-20 tokens from one wallet address to another.
  • Update ERC-20: Manage any config on the ERC-20 contract, eg: transfer restrictions.
