How to get all tokenIDs in an NFT contract
The code snippet below looks for the startTokenId of the contract (which is usually 0) and the current largest tokenId (maxId). You will get all the tokenIds of the given contract by getting all the bigint from startTokenId to maxId
Note: If you’re sure the contract’s startTokenId is always 0, you can skip using startTokenId(). For thirdweb’s ERC1155 contract, the tokenId starts from 0
// Example for an ERC-721 contract
const options = {
contract: theNftContract,
};
const [startTokenId_, maxSupply] = await Promise.allSettled([
startTokenId(options),
nextTokenIdToMint(options),
totalSupply(options),
]).then(([_startTokenId, _next, _total]) => {
// default to 0 if startTokenId is not available
const startTokenId__ =
_startTokenId.status === "fulfilled" ? _startTokenId.value : 0n;
let maxSupply_: bigint;
// prioritize nextTokenIdToMint
if (_next.status === "fulfilled") {
// because we always default the startTokenId to 0 we can safely just always subtract here
maxSupply_ = _next.value - startTokenId__;
}
// otherwise use totalSupply
else if (_total.status === "fulfilled") {
maxSupply_ = _total.value;
} else {
throw new Error(
"Contract requires either `nextTokenIdToMint` or `totalSupply` function available to determine the next token ID to mint",
);
}
return [startTokenId__, maxSupply_] as const;
});
const maxId = maxSupply + startTokenId_;
const allTokenIds:bigint[] = [];
for (let i = startTokenId_; i < maxId; i++) {
allTokenIds.push(i);
}
console.log(allTokenIds); // [startTokenId_, 1n, 2n, ... maxId]
