Stablecoin Payments Glossary
Mempool
A mempool is the pool of pending blockchain transactions awaiting inclusion in a block.
Explanation
After a payment is submitted, it may remain in the mempool until validators include it in the ledger. Congestion or low fees can delay this process and affect payment timing.
Why it matters
Mempool dynamics influence confirmation speed, user experience, and operational reliability in stablecoin payments.
