ERC1155Drop

import "@thirdweb-dev/contracts/extension/Drop1155.sol";

The Drop1155 smart contract is an extension meant for distributing ERC1155 tokens. It allows setting up multiple claim phases unlike ERC1155DropSinglePhase. This series of claim phases is ordered by their respective startTimestamp.

This extension implements the 'Drop' distribution mechanism: set multiple claim phases with restrictions such as a price to charge, an allowlist etc. for the public / allowlisted mint of your tokens.

It is recommended to use this extension alongside the LazyMint extension.

The Drop1155 extension is an abstract contract, and expects you to implement the following functions by yourself:

This is an example smart contract demonstrating how to inherit from this extension and override the functions to add (optional) custom functionality.
