Story Protocol SDK Documentation

Overview

The Story Protocol SDK is a TypeScript library that provides an interface to interact with the Story Protocol smart contracts. It includes classes for managing NFTs, handling various workflows, and dealing with errors specific to the protocol.

Installation

npm install story-protocol-sdk

Main Components

SPGNFT

The SPGNFT class provides methods to interact with the SPGNFT (Story Protocol Generative NFT) contract.

Usage

import { SPGNFT, ethers } from 'story-protocol-sdk';

const provider = new ethers.providers.JsonRpcProvider('YOUR_RPC_URL');
const signer = new ethers.Wallet('YOUR_PRIVATE_KEY', provider);
const spgnft = new SPGNFT('SPGNFT_CONTRACT_ADDRESS', signer);

// Example: Minting an NFT
try {
  const tx = await spgnft.mint('RECIPIENT_ADDRESS', 'NFT_METADATA_URI');
  console.log('NFT minted:', tx.hash);
} catch (error) {
  if (error instanceof SPGNFTError.MintingDenied) {
    console.error('Minting denied. You may not have the minter role.');
  }
  // Handle other errors...
}

Workflows

The SDK provides classes for different workflows in the Story Protocol:

  • RegistrationWorkflows
  • LicenseAttachmentWorkflows
  • GroupingWorkflows
  • DerivativeWorkflows (not fully implemented yet)

Usage Example: RegistrationWorkflows

import { RegistrationWorkflows, WorkflowStructs, ethers } from 'story-protocol-sdk';

const registrationWorkflows = new RegistrationWorkflows('REGISTRATION_WORKFLOWS_ADDRESS', signer);

// Example: Creating a new collection
const collectionAddress = await registrationWorkflows.createCollection(
  'My Collection',
  'MC',
  1000,
  ethers.utils.parseEther('0.1'),
  'MINT_FEE_TOKEN_ADDRESS',
  'MINT_FEE_RECIPIENT_ADDRESS',
  await signer.getAddress(),
  true,
  true
);

console.log('New collection created at:', collectionAddress);

// Example: Minting and registering an IP
const ipMetadata: WorkflowStructs.IPMetadata = {
  ipMetadataURI: 'https://example.com/ip-metadata',
  ipMetadataHash: ethers.utils.keccak256(ethers.utils.toUtf8Bytes('IP Metadata')),
  nftMetadataURI: 'https://example.com/nft-metadata',
  nftMetadataHash: ethers.utils.keccak256(ethers.utils.toUtf8Bytes('NFT Metadata'))
};

const { ipId, tokenId } = await registrationWorkflows.mintAndRegisterIp(
  collectionAddress,
  await signer.getAddress(),
  ipMetadata
);

console.log('Minted and registered IP:', { ipId, tokenId });

Error Handling

The SDK provides custom error classes for different types of errors that may occur during interactions with the Story Protocol contracts. These include:

  • SPGError
  • RegistrationWorkflowsError
  • LicenseAttachmentWorkflowsError
  • DerivativeWorkflowsError
  • GroupingWorkflowsError
  • SPGNFTError

You can catch and handle these errors to provide more specific error messages or take appropriate actions in your application.

Types and Interfaces

The SDK includes several TypeScript interfaces and types to help with type checking and autocompletion:

  • SPGNFTConfig
  • WorkflowConfig
  • WorkflowStructs.IPMetadata
  • WorkflowStructs.SignatureData
  • WorkflowStructs.MakeDerivative
  • PILTerms

Constants

  • ADMIN_ROLE: The default admin role (0x1)
  • MINTER_ROLE: The default minter role (0x1)
