DropSinglePhase (ERC1155)

import "@thirdweb-dev/contracts/extension/DropSinglePhase1155.sol";

The DropSinglePhase1155 smart contract is an extension meant for distributing ERC1155 tokens.

This extension implements the 'Drop' distribution mechanism: set 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.

Usage

The DropSinglePhase1155 extension is an abstract contract, and expects you to implement the following functions by yourself:

NameTypeDescription
_afterClaiminternal virtualRuns after every claim function call.
_beforeClaiminternal virtualRuns before every claim function call.
_collectPriceOnClaiminternal virtualCollects and distributes the primary sale value of NFTs being claimed.
_transferTokensOnClaiminternal virtualTransfers the NFTs being claimed.
_canSetClaimConditionsinternal view virtualRuns on every attempt to set the claim condition on the contract. Returns whether the claim condition can be set in the given execution context.

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