The Dencun improve in March 2024 was a major milestone for Ethereum, nevertheless it additionally caused unexpected challenges, significantly for Layer 2 networks.

Christine Kim, a researcher at Galaxy, highlighted that this improve inadvertently led to a rise in transaction failures throughout these networks.

Ethereum’s Layer 2 Networks Face Challenges

Kim’s August 21 analysistitled “150 Days After Dencun,” revealed that for the reason that fee-reducing improve, there was a notable rise in failed transactions and bot exercise on Layer 2 networks.

The report highlighted that after the activation of EIP-4844, Ethereum L2’s day by day transactions greater than doubled, rising by 6.65 million inside 150 days. Nonetheless, this improve in transaction exercise has additionally been accompanied by the next charge of failures, which Kim attributes to bot exercise pushed by the diminished charges.

A lot of the transaction failures are linked to extremely lively addresses, that are possible bots. The low charges on L2s could also be encouraging this spike in bot exercise. For common customers with regular transaction volumes, the failure charges are solely barely increased than they had been earlier than the Dencun improve.

Analysis confirmed that Arbitrum, Base, and OP Mainnet have encountered notable will increase within the proportion of failed transactions. Base noticed its failure charge climb to 21%, Arbitrum to fifteen.4%, and OP Mainnet to 10.4% inside 150 days following Dencun. However, the low-activity addresses with 5 or fewer day by day transactions noticed a most failure charge of 4.02% throughout all networks.

OP Mainnet’s failure charge for these addresses decreased since March 13, 2024, whereas Base’s charge has solely barely elevated. Curiously, Arbitrum’s failure charge for low-activity addresses surged by 545% post-Dencun.

The discount in rollup transaction prices and the rise in failures amongst high-activity addresses recommend that bot exercise is probably going driving the elevated failure charges on these rollups, as per the researcher.

Solana Faces Comparable Woes

Transaction failure charges should not solely restricted to Layer 2 networks. Actually, the favored Layer 1 community, Solana, additionally has a excessive charge of transaction failure.

In its latest reportCoinbase acknowledged that of all Solana non-vote transaction charges, between 25% and 45% are spent on failed transactions.
