Voucher NFT Collection

Overview

Each Voucher consists of two parts: an NFT (representing ownership) and an ERC6551Account (representing data). The Voucher NFT must belong to a Vemo Voucher NFT Collection, which is associated with a specific token address (locked asset) and must be pre-deployed before minting vouchers.

Types of Voucher NFT Collections

1. Manual TokenURI Provision: TokenURI must be provided (selfhost tokenURI) but the collection's name and symbol can be customized according.

2. Auto-Generating TokenURI (Coming Soon): Vemo will offer an algorithm to automatically generate TokenURIs based on a provided template. The collection's name and symbol will be automatically generated based on Vemo's standard.

How to create a collection

The VoucherFactory provides interfaces for creating VoucherCollection,

The deployment contract addresses of VoucherCollection.sol on different chains:

Chain	Address
Avalanche Fuji Testnet	0x65B903D7903d277bE600B8524a759aBEa3CC7e1A
Avalanche Mainnet	0xbB740E17f3c177172CaAcCef2F472DB41b9b1d19
Bnb Mainnet	0x9869524fd160fe3adDA6218883B6526c0977D3a5

1. Manual TokenURI Provision

• createVoucherCollection: Create a Collection that associated with a token address, name and symbol need to provide

function createVoucherCollection(
        address token,
        string calldata name,
        string calldata symbol,
        IFactory.CollectionSettings calldata settings
    ) public nonReentrant returns (address) {}

struct CollectionSettings {
    uint96 royaltyRate;
    bool isSoulBound;
    FreeMintableType isFreeMintable;
    bool isSemiTransferable;
}

enum FreeMintableType {
    NON_FREE_MINTABLE,
    FREE_MINT_COMMUNITY,
    FREE_MINT_WHITELIST
}

1. Auto-Generating TokenURI (Coming Soon)

• createAutoURIVoucherCollection: Create a Collection that associated with a token address, all tokenURI of tokens will be automatically generated.

function createAutoURIVoucherCollection(
        address token,
        address descriptor
    ) public nonReentrant returns (address) {}
