GM! Noticed anything different when transacting on Ethereum lately? Fees are now so cheap they're down to sub-cent levels, so we had to show more decimal places. Never been a better time to use Ethereum!

On Etherscan, we now link to the correct explorer when a pasted tx hash is from another chain. Token pages now feature transfer heatmaps and analytics. We've also introduced a Lite API Plan and updated the API Free Tier coverage.

In this issue, we explore how the Fusaka upgrade scales Ethereum, boosts blob capacity, and improves UX.

Pick of the Month

Transaction: Consuming ~59.6M Gas in a Block

The transaction occupies 99.3% of a block, which breaks the ZK provers. The Fusaka upgrade limits transactions to ~16.6M gas to prevent this.

Block 23937600: $1,235 of Blob Fees

Only 7 hours after Fusaka went live, blob congestion plus the newly introduced blob price floor upgrade sent blob fees spiking.

Apps to Try

As the world goes onchain, here are some apps you can explore:

Spark
A DeFi app that lets you earn yield on assets like ETH and stablecoins through Spark Savings. Yields are around 4% APY and may vary. There are no lockups, and you can withdraw anytime. Learn how.

SuperRare
A curated online marketplace that allows artists to issue, collect, and trade rare digital art backed by NFTs on Ethereum. Every piece of art is a single edition and unique without duplicates.

Note: We're highlighting apps by the community, please do your own research before using them!

Pro Tip

Decompile any closed-source contracts
On the contract page in Etherscan, open the Cards tab and look for EVM Decompiler. There, you can get insights into unverified contracts like top MEV bots and suspected phishing tokens with this LLM-enabled card.
