opBNB Low Fee Guide

Explore why opBNB fees are so low, how Layer 2 pricing works, and why small daily transactions can be much cheaper on opBNB than on many alternatives.

Why opBNB is cheaper

opBNB is a Layer 2 built for high throughput and low cost. Official FAQs say small daily transactions can cost around $0.005 per transaction, making it suitable for frequent onchain actions.

Two-part fee structure

opBNB fees include an L2 execution cost and an L1 data cost. This is different from a plain Layer 1 transfer because batches must still be settled back to BNB Smart Chain.

Speed and capacity

The network documentation highlights a 1 second block time and a 100M per block gas limit. That combination supports fast confirmations and stable fee behavior under load.

Best use cases

Small payments, gaming, social apps, and high-frequency user actions benefit most when fees stay near micro-payment territory.
