The Taipei Ethereum Meetup (TEM) continues to serve as a vibrant hub for blockchain developers, researchers, and enthusiasts in Taiwan and beyond. With a growing collection of technical deep dives, community experiments, and forward-looking analyses, TEM has become a go-to source for understanding emerging trends in Ethereum, Layer 2 solutions, decentralized applications (dApps), and cryptographic advancements.
This curated overview synthesizes key insights from recent TEM contributions, offering readers a comprehensive look into pivotal developments shaping the future of Web3 — from EIP upgrades and zero-knowledge proofs to wallet security and cross-chain interoperability.
Ethereum Pectra Hard Fork: What You Need to Know
Scheduled for deployment on the Ethereum mainnet in early 2025, the Pectra hard fork introduces a suite of 11 Ethereum Improvement Proposals (EIPs) designed to enhance scalability, usability, and security. Among the most impactful are:
- EIP-2537: Adds precompiles for BLS12-381 elliptic curve operations, enabling more efficient signature aggregation and paving the way for advanced zk-cryptography.
- EIP-7702: Introduces
AUTHandAUTHCALLopcodes that allow account abstraction by temporarily delegating control of an externally owned account (EOA) to a smart contract. This upgrade aims to streamline user onboarding and improve dApp interaction experiences.
These changes are part of Ethereum’s long-term vision to become a more modular, user-friendly, and scalable platform. The Pectra upgrade is expected to lay critical groundwork for further innovations in account abstraction and Layer 2 integration.

L2Beat: Your Guide to Ethereum’s Layer 2 Ecosystem
For anyone navigating the complex landscape of Ethereum Layer 2 (L2) networks, L2Beat has emerged as an indispensable resource. It offers detailed, transparent tracking of nearly all major L2 solutions, including:
- Total Value Locked (TVL)
- Architecture breakdowns (e.g., Optimistic vs. ZK Rollups)
- Contract addresses and admin key permissions
- Data availability layers
- Security levels and risk factors
L2Beat doesn’t just aggregate data — it empowers users to make informed decisions about where to deploy capital or build applications. With rising concerns around centralization and trust assumptions in some rollups, this level of transparency is crucial for maintaining ecosystem health.
As Ethereum scales through rollups, tools like L2Beat will play an increasingly vital role in ensuring accountability and fostering trustless innovation.
ERC-4337 and Account Abstraction: Building Gasless dApps
One of the most exciting developments in user experience is ERC-4337, which enables account abstraction without requiring consensus-level changes. Johnson’s recent experiment at TEM demonstrates how developers can implement gasless transactions in dApps using this standard.
By leveraging smart contract wallets, users no longer need ETH in their wallet to pay gas fees. Instead, relayers or sponsors can cover transaction costs, making onboarding seamless for newcomers.
Key components of the implementation include:
- Bundler service: Aggregates user operations into a single transaction.
- Paymaster contracts: Sponsor gas fees on behalf of users.
- Frontend integration: Enables smooth UX with MetaMask or other wallets via libraries like
ethers.js.
This approach was tested in a decentralized stipend distribution system, proving its viability for real-world applications such as DAO payouts, airdrops, and community rewards.
CoW AMM: A MEV-Resistant Liquidity Solution
CowSwap’s innovative CoW AMM (or FM-AMM) reimagines automated market makers by eliminating swap fees and mitigating Miner Extractable Value (MEV). Unlike traditional AMMs that rely on constant liquidity pools, CoW AMM uses order book semantics combined with batch auctions and peer-to-peer settlements.
Key advantages:
- Zero swap fees for traders
- MEV resistance through time-locked order batching
- Improved price execution via solver competition
This model aligns incentives across traders, liquidity providers, and solvers, creating a fairer trading environment. For liquidity providers, returns come from arbitrage opportunities captured during batch settlements rather than fees.

EIP-1153: Transient Storage Opcodes Explained
A lesser-known but highly efficient upgrade, EIP-1153, introduces transient storage to the Ethereum Virtual Machine (EVM). Unlike persistent storage (sstore/sload), transient storage is cleared after each transaction, making it ideal for temporary data caching.
Two new opcodes are introduced:
tstore(key, value)tload(key)
Because transient storage doesn’t affect the state root, it avoids the high gas costs associated with sstore. This makes it perfect for use cases like:
- Tracking loop iterations
- Storing intermediate calculation results
- Preventing reentrancy without using locks
Developers building gas-efficient smart contracts should consider integrating EIP-1153 patterns where applicable.
Cross-Chain Interoperability: Current State and Challenges
Despite rapid growth in multi-chain ecosystems, cross-chain interoperability remains fraught with risks. Queenie C.’s analysis highlights three primary models:
- Lock-and-Mint Bridges: Assets are locked on the source chain and minted as wrapped versions on the destination chain.
- Liquidity Networks: Use local liquidity pools for fast swaps (e.g., Hop Protocol).
- General Message Passing Protocols: Enable arbitrary data transfer between chains (e.g., LayerZero).
Each model faces trade-offs between speed, security, and decentralization. Common challenges include:
- Oracle centralization
- Smart contract vulnerabilities
- Liquidity fragmentation
- MEV across bridges
The future likely lies in zk-based bridges, which use zero-knowledge proofs to verify cross-chain state transitions trustlessly. Projects like Polymer and TeleportDAO are already exploring this path.
Wallet Security: The Critical Role of Seed Phrases
Albert Cheng shares a cautionary tale about digital asset security after a browser update broke his MetaMask extension — prompting him to reinstall and nearly lose access to funds due to poor seed phrase management.
His experience underscores a fundamental truth: your seed phrase is your ultimate backup. Without it, recovery is impossible.
Best practices:
- Never store seed phrases digitally (no screenshots, cloud notes, or emails)
- Use hardware wallets for large holdings
- Test recovery before funding a new wallet
- Consider social recovery options (e.g., Safe{Wallet})
As self-custody becomes standard in Web3, personal responsibility for security must follow.

Frequently Asked Questions
What is the Pectra hard fork?
Pectra is an upcoming Ethereum upgrade expected in 2025 that includes EIPs like 2537 and 7702 to enhance cryptography support and enable advanced account abstraction features.
How does ERC-4337 enable gasless transactions?
ERC-4337 allows third parties (paymasters) to sponsor gas fees for users via smart contract wallets, removing the need for users to hold ETH for transactions.
Is L2Beat safe to rely on for investment decisions?
While L2Beat provides accurate and transparent data, it should be used alongside independent research. Always verify contract addresses and understand risk scores before interacting with any L2.
Why is CoW AMM considered MEV-resistant?
CoW AMM batches orders and settles them off-market via solvers, reducing opportunities for front-running and sandwich attacks common in traditional DEXs.
Can transient storage be used for permanent data?
No. Transient storage is cleared at the end of every transaction. It's only suitable for temporary variables during execution.
What’s the safest way to back up a crypto wallet?
The safest method is writing your 12–24 word seed phrase on paper or metal and storing it offline in a secure location. Avoid any digital storage.
