What is Mad Mints?

Improves the speed of minting transactions. With this approach, you'll be able to handle high demand and experience incredible UX. Armani found this approach and named "Mad Mints".

Detailed Explanation by ChatGPT-3.5

3 STEPs to Implement Mad Mints.

STEP1

Allocate Durable Nonces

STEP2

Buffer transactions into queue

STEP3

Async process

Allocate 10,000 durable nonces: Nonces are integer values used to differentiate transactions with the same key. By allocating 10,000 durable nonces, you ensure that transactions can be easily tracked and duplicates can be avoided. These nonces are stored in persistent memory and won't be deleted even during reboots or upgrades.

Docs: https://solanacookbook.com/references/offline-transactions.html

Use web2 infrastructure to buffer transactions into a queue: Employ web2 infrastructure, which refers to traditional web infrastructure, to buffer incoming transactions into a queue. Instead of sending transactions directly to the chain, you add them to the queue for processing. This helps handle sudden bursts of transactions and enhances scalability.

Asynchronously process the queue one by one: Process the transaction queue asynchronously, meaning you handle each transaction one by one. This allows you to manage the order in which transactions are processed. You won't move on to the next transaction until the current one has completed all its processing steps.

Conclusion of Mad Mints

If you need fine-tuning speed, you should use Mad Mints.

256hax

5

Pros

(Value)

  • Mad Mints is 16 to 27 times faster than the standard.
  • The more NFTs you mint, faster it tends to become.
  • Easy to implement Mad Mints.

Example Case

  • It is useful when fine-tuning speed is required in milliseconds.�e.g. Minting Site, DEX and Fully On-chain site.
  • If speed is not a priority, standard transaction method is sufficient.

Cons

  • Create and store Durable Nonce Account in advance.
  • Total fees are higher, ranging 0.0014 - 0.02 SOL per transaction.�e.g. 10K mints are up to 200 SOL
  • (Option) You may need to build a queueing system for transactions.

This conclusion is unofficial, in my opinion.
