【问题描述】：

当我尝试用 37 个 NFT 序列号调用TokenBurnTransaction() 时，出现返回错误BATCH_SIZE_LIMIT_EXCEEDED.因此，我想知道在单个函数调用中我可以燃烧的最大量是多少。

【解决方案1】：

您可以在单个交易调用中铸造或销毁的最大序列数为 10。

请参阅此代码示例：

// BURN 10 SERIALS IN THE NFT COLLECTION
let tokenBurnTx = await new TokenBurnTransaction()
    .setTokenId(tokenId)
    .setSerials([1, 2, 3, 4, 5, 6, 7, 8, 9, 10])
    .freezeWith(client)
    .sign(supplyKey);
let tokenBurnSubmit = await tokenBurnTx.execute(client);

如果您检查相应交易的镜像节点 REST API，您将看到所有 10 个铸币/销毁。
