Sale contract & multi sale contracts

the contracts in contracts/flat are the final ones because they will be verified

Private Sales

private sales implement royalty splits

• between flexible numbers of recipients
• with initial sale and resale having different splits
• defined by pool
• where each specific token being assigned to a pool

So token#1 can have a different token split from token#2

Token Deployment

Assuming

• locking1, locking2 - subscribing to either of these contracts lets you in
• "You need..." the revert error message if nothing locked for first sale
• [creator1,patron1] the initial share (see above)
• [creator1R,patron1R] resale share
• "C+P" - name of this Pool

m1155 = await M1155.deploy(
        artistAddress,
        saleContractAddress,
        [locking1.address,locking2.address],
        "You need to be a MINTY patron or TEST PROJECT patron",
        100,
        [creator1,patron1],
        [creator1R,patron1R],
        "C+P"
)

Adding another pool

await m1155.connect(addr1).addPools([creator2,musician2,patron2],[creator2R,musician2R,patron2R],"C+P+M")

Sale Contract

Putting a new item for sale

sale.offerNew(
    m1155.address,                    // token contract
    11,                               // tokenId
    "hash",                           // URI hash
    180,                              // quantity
    ethers.utils.parseEther("0.205"), // unit price
    1                                 // poolID
)

Resale does not need to know the poolID

sale.offerResale(
     m1155.address,                    // token contract
     11,                               // tokenId
     5,                                // quantity
     ethers.utils.parseEther("0.205")  // unit price
)

window.ethereum.request({ 
    method: 'wallet_addEthereumChain', 
    params: [
        { 
            chainId: '0x38', 
            chainName: 'Binance Smart Chain', 
            nativeCurrency: { name: 'BNB', symbol: 'BNB', decimals: 18 }, 
            rpcUrls: ['https://bsc-dataseed.binance.org/'], 
            blockExplorerUrls: ['https://bscscan.com/'] 
        }
    ]
