Decoding blockchain data for money-market protocols.

In my new Blockchain Decoding Series, I walk through exactly how to take raw, unreadable Ethereum event logs from AWS public datasets and transform them into clean, structured data for Aave V1/V2/V3 using Apache Spark!

@SrujanGowda_10 Try tiger data

@yulesa ok, good one

@sns @_christian_obi @len3_x @colosseum @ns @SuperteamMY Amazing

[Freeman🌼 @Freemandayly]

Just updated my EVM blockchain log decoder pipeline!

Added unified support for @compoundfinance (V1, V2, V3) alongside @Aave.

Refactored the core logic to be completely protocol-agnostic. Ready to scale and easily onboard more money markets!

@SpecterAnalyst @TesseraDao Crime

[Specter @SpecterAnalyst]

A project on BNB Chain, @TesseraDao , has been exploited. The attacker minted 99M $TSR and dumped the tokens for $2.4M.

As a result, $TSR plunged 99%.

The attacker has already has deposited them into Tornado Cash.

Theft address:
0x2201037A1755eC48eC5f00Fea21A10A9E56f2Dd8

Meanwhile, the UXLINK exploiter is also actively depositing funds into Tornado Cash. So far, approximately $7.1M has been deposited.

Stay smart.

@len3_x @solana Nice design

@sluongng Agent will always find a wat to have root access. Now its through docker .

@SpecterAnalyst @ChangeNOW_io @gravity_bridge Great job brother

[Freeman🌼 @Freemandayly]

@SrujanGowda_10 Thanks for this. It interesting

[Freeman🌼 @Freemandayly]

@SpecterAnalyst @gravity_bridge This is getting worse every day

what i covered:
🔹 Modular ABI mapping for Aave protocols (Borrow, Repay, Liquidations)
🔹 Low-level log decoding via eth-abi inside PySpark UDFs
🔹 High-performance batch processing pipelines on S3

[Freeman🌼 @Freemandayly]

@0xKofi @opencode @herd_eco This is interesting

[Freeman🌼 @Freemandayly]

@len3_x @sns @solana Congratulations

Data engineering is the backbone of every data-driven application, and the modeling approach is central to how the product performs.

At Tradeslens, I used dbt for data modeling, which enables efficient and reliable querying.

Kelp DAO exploit

I built ChainTrace Forensic, a reproducible forensic pipeline that

• Extracts the attacker's complete fund flow on-chain
• Visualizes the trace of every transfer
• Simulates fund movement step-by-step
