How has EIP-4844 impacted L2 costs?

1/ As the table below shows, most L2s experienced a 90%+ reduction in their L1 costs after adopting EIP-4844 blobs

L1 costs = Gas and Blob Fees for batch posting transactions + Gas Fees for proof verification transactionsImage
2/ Since their costs dropped by an order of magnitude, L2s could afford to reduce the gas fees they charged users.

As shown in the charts below, the cost of making common transactions like ETH transfers or Uniswap trades has dropped 90%+ on most L2s.

3/ I look forward to seeing all the new use cases that this low-fee environment enables!

For more insights into how EIP-4844 has transformed the L2 business model, and links to the code for all these charts, check out my blog post 👇

CORRECTION: Manta, Orderly, Lyra, Hypr and Aevo post their batches on Celestia instead of using EIP-4844 blobs. Credit to @emilianobonassi for the callout!

I often get asked the question, "What's happening onchain?"

The answer usually lies in incentives. Every new wave of onchain activity is driven by a new incentives playbook. For example 👇
[2020] Liquidity mining

- Compound, a lending protocol, kicked off the liquidity mining trend in June 2020 with a wildly successful token incentive program. Compound's TVL spikes from $100M to $600M in one week

- Every DeFi protocol under the sun copied this playbook and DeFi summer entered full swing.Image
[2021] Joint Liquidity Mining

In early 2021, the Polygon Foundation launched joint liquidity mining programs with popular DeFi protocols.

First was Aave. Polygon gave $40M worth of MATIC to lenders and borrowers on Polygon Aave. Users bridged to use Polygon Aave to earn these incentives -> Polygon Aave's TVL grew rapidly.

Polygon repeated this playbook with other protocols like Curve and Sushiswap. Polygon’s TVL jumped from ~$100M to high billions within two months.

The playbook was replicated by a host of other chains like Avalanche (see Avalanche rush) and this drove the alt-L1 rotation in 2021.Image

Learning crypto data science changed my life and was 100% free.

If you're looking for a change (I was a transport planner), start coding 1 hour a night. More on weekends.

Pick a simple @DuneAnalytics project. Learn just enough to build it. Pick a bigger project. Repeat.
It took me 3 years to get to my current level of crypto data proficiency (preceded by 3 years of writing coding in other fields). Here are some free resources you can use to get there 10X faster 👇
1. SQL and Blockchain data

Go to Headmaster Andrew's twitter account (@andrewhong5297) 🧙‍♂️✨

Click the link in his bio.

You'll find intro guides for Ethereum, Solana, and Bitcoin Dune data analysis.

Pick one and get it done.

Here is what rollups spent on posting data to Ethereum in November:

1. Arbitrum - $4.4M
2. Linea - $3.7M
3. Optimism - $2.508M
4. zkSync Era - $2.506M
5. Scroll - $1.43M
6. Base - $1.34M
7. Polygon zkEVM - $678k
8. Starknet - $500k
9. Zora - $211k
10. Aevo - $109k
11. Orderly - $101.2k
12. zkSync Lite - $101k
13. Public Goods Network - $95k
14. Mode - $31k
15. Lyra - $17kImage
You can query insights like this using the Rollup Economics Spell on @DuneAnalytics.

Huge thanks to Archwizard @LehmannLorenz for adding Scroll and Linea to the dataset last week! 🧙‍♂️✨

It's been 5 months since I started that Spell. Feels really exciting to see more wizards building it up 🥹

Here's an example of how to use the Spell 👇

The rollups I have revenue data for made more than enough to cover their costs.

Their gas fee systems are designed to cover the L1 cost + add a premium.

In November, revenue from gas fees was:

Arbitrum - $5.94M
zkSync Era - $5.48M
Optimism - $3.09M
Base - $1.6M

How to become a DeFi frontend engineer (starting from scratch):
Step 0: Learn basic JavaScript and HTML from a free resource of your choice (CodeAcademy, w3schools, freecodecamp .etc)

For JavaScript, if you understand variables, functions, if statements, and while loops then you're fine.
Step 1: Work through the reading and exercises in the 'Get Started' section of the React documentation (Quick start, Tic-tac-toe, Thinking in React .etc)

React is the most popular library for frontend engineering

I'm writing a guide to generating Dune queries with GPT.

It's a work in progress. Lots of new lessons in the pipeline, and I'll continuously update to include new Dune features.

If you want to read it, subscribe to 0xTrends Premium ($25/month).

0xtrends.com/gpt-crypto-dat…
Limitations:

GPT is not deterministic; there is an element of randomness in how it responds to prompts.

A good prompt will usually generate passable DuneSQL code, but not always.

I include examples of common mistakes GPT makes and tips on how to deal with those hallucinations
The guide currently covers:

- Analysing aggregated data with Dune Spells (eg. all NFT trades, all DEX swaps)

- Investigating specific protocols with Dune Decoded Projects

- Using raw transaction data to query contract usage stats and ETH transfers
