Microtransactions
16/04/2026
Microtransactions are payments of very small value — ranging from fractions of a cent to a few dollars. Traditional payment systems (credit cards, bank transfers) make microtransactions impractical because fixed fees often exceed the transaction value itself.
Why traditional payments fail for microtransactions
A credit card transaction typically carries a ~2–3% fee plus a fixed ~$0.30 charge. For a $0.05 payment, the fee is 6x the transaction amount. This makes micropayments economically unviable through legacy financial rails.
How crypto enables microtransactions
- On-chain (Layer 1) — Bitcoin and Ethereum base layer fees fluctuate and can be high, making them unsuitable for small payments during congested periods
- Layer 2 solutions — the Lightning Network (Bitcoin L2) enables payments of any size with fees measured in fractions of a cent, settled nearly instantly
- Low-fee blockchains — some chains (Litecoin, Nano, etc.) have very low base fees suitable for small payments
Relevance to miners
Mining pools pay out miners frequently — often multiple times per day for small operations. These payouts are essentially microtransactions. High on-chain fees can make small payouts uneconomical. Kryptex Pool handles this by batching payouts and optimizing fee timing. Miners with very small hashrates benefit most from pools with low minimum payout thresholds.
