Title: Solana: Getting Block Height Exceeded Errors When Mining NFTs Using Metaplex

Introduction

Mining non-fungible tokens (NFTs) on the Solana blockchain can be an exciting experience. However, I have encountered an error that is causing problems when trying to mine NFTs on the platform: “Block Height Exceeded”. This article will walk you through the troubleshooting steps and provide solutions to resolve this issue.

The Problem

When trying to mine NFTs using Metaplex, I noticed that I was getting the infamous “Block Height Exceeded” error. This occurs when my transaction exceeds the maximum allowed block height on Solana. As a result, the transaction is rejected by the blockchain and I have to restart from scratch.

The Solution

Fortunately, there are some workarounds to resolve this issue:

1. Add a Priority Fee to Tx

One approach to address this issue is to add a priority fee to your transaction using the --priority-fee option when sending the NFT mining transaction. Here is an example of how to do it:

solana mint --tx-priority-fee=1000 mymetaplex-nft.json

This sets the priority fee for the transaction to 1000 SPK (Solana Plasma Kintsugi). The–priority-feeoption is a new feature introduced in Solana 1.10, and allows you to set a custom transaction fee.

2. Use a different transaction structure

Alternatively, you can try using a different transaction structure that does not rely on the–priority-feeoption. One approach is to use thesolana mint –tx-type=script` command with a script that includes a function that adds the priority fee:

solana mint --tx-type=script mymetaplex-nft.json \
"function addPriorityFee(amount: u128) {
if (amount > 0) {
const fee = await solana.client.fee(1000);
return amount + fee;
} else {
return amount;
}
}"

This script adds the priority fee to the transaction amount before minting the NFT.

3. Check Solana Documentation and Forums

Before trying these solutions, I recommend checking the official Solana documentation and forums for updates or new information on this issue.

Conclusion

Mining NFTs on the Solana blockchain can sometimes be a bit of a challenge, but with the right approach, you should be able to resolve the “Block Height Exceeded” error. By adding priority fees to your transactions or using alternative transaction structures, you can overcome this issue and successfully mine your NFTs.

Recommendations

  • Be sure to check the latest Solana documentation for changes or updates to this issue.
  • If you are having issues with Metaplex, try updating to the latest version of the platform (1.10.x or later).
  • Consider using a different transaction structure that does not rely on priority fees.

I hope this article was helpful in resolving your “Block Height Exceeded” error when mining NFTs on Solana!
