Title: Solana: Getting Block Height Exceed Errors when minting NFTs using Metaplex

Introduction

Minting non-fungible tokens (NFTs) on the Solana blockchain can be a thrilling experience. However, I’ve encountered an error that’s causing issues with my attempts to mint NFTs on the platform: “Block height exceeded”. This article will guide you through troubleshooting steps and provide solutions to resolve this issue.

The Issue

When attempting to mint an NFT using Metaplex, I’ve noticed that I’m 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 need to restart from the beginning.

The Solution

Fortunately, there are some workarounds available to resolve this issue:

1. Add 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 minting transaction. Here’s 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-fee option is a new feature introduced in Solana 1.10, and it allows you to set a custom fee per transaction.

2. Use a Different Transaction Structure

Alternatively, you can try using a different transaction structure that doesn’t rely on the --priority-fee option. One approach is to use the solana 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’s Documentation and Forums

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

Conclusion

Minting NFTs on the Solana blockchain can be a bit challenging at times, 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 mint your NFTs.

Recommendations

• Make sure to check the latest Solana documentation for any changes or updates on this issue.

• If you’re experiencing issues with Metaplex, try updating to the latest version of the platform (1.10.x or later).

• Consider using a different transaction structure that doesn’t rely on priority fees.

I hope this article has been helpful in resolving your “Block height exceeded” error when minting NFTs on Solana!
