Forgot to post earlier, but here's last week's TWIL. Last week I learned about transaction types in Ethereum and @ZKsync. Ethereum ♦️ and ZKsync 🧬 use different transaction types to optimize for scalability, gas efficiency, and account abstraction. Let’s break it down! 👇

ZKsync Transaction Types 🧬 Type 113 (0x71): - Enables advanced features like account abstraction. - Required for deploying smart contracts on ZKsync. - Adds fields like:

+ gasPerPubData: Cost of L2 pubdata submitted to L1. + customSignature: For non-EOA accounts. + factoryDeps: Deployed smart contract bytecode.

Ethereum and ZKsync Transaction Types ♦️🧬 Type 0 (Legacy): - Used before EIP-1559. - Still supported via Foundry’s --legacy flag.

♦️🧬 Type 1 (0x01): - Introduced with EIP-2929. - Adds an accessList for predeclaring addresses and storage keys. - Saves gas on cross-contract calls by reducing state access costs.

♦️🧬 Type 2 (0x02): - EIP-1559, introduced in the London Fork. - Handles congestion with: * maxPriorityFeePerGas: User-defined priority fee. * maxFeePerGas: Total fee limit. (Notes: ZKsync supports Type 2 but currently ignores maxFee parameters.)

+ max_blob_fee_per_gas: Separate gas market for blob data. + blob_versioned_hashes: Tracks blobs associated with the transaction. 🔥 Blob fees are burned upfront, so failed transactions are not refundable.

That’s it for this week! These transaction types highlight how ZKsync can still provide a similar experience to that on Ethereum, while providing more functionality with new txn types Next time, I’ll cover Account Abstraction 😎
