Buy()
Triggers the buy flow to purchase a token. Will only work during a public sale. This is equivalent to what web3 developers refer to as "mint".
If a user has not connected their wallet, buy() will automatically call connect()
| Name | Type | Required | Description |
|---|---|---|---|
| amount | Number | Y | # of tokens to mint/buy |
| tokenId | Number | N | A specific token to buy/mint. For 721 contracts this should be 0. For 1155 contracts this should be the tokenId. TokenIds can be found in the dashboard in the "Tokens" tab. |
| wait | Boolean | N | Blocks the return of this function until the transaction has completed on network by calling waitForTransaction(). Note that the transaction may take a while to resolve depending on network traffic. |
Response
{
"hash": "string"
}
Example Usage
const amount = 1;
const waitForTransaction = true;
// ERC721
const transaction = await contract.buy(amount, 0, waitForTransaction);
// ERC1155
const tokenId = 0;
const transaction = await contract.buy(amount, tokenId, waitForTransaction);
// Optional (if waitForTransaction is false)
const status = await contract.getTransactionStatus(transaction);
Returns a transaction with the network hash which can be used to poll for completion or in the waitForTransaction function.
On Polygon networks, an approve transaction is also triggered to give the contract access to the user's WETH.
