This Week's Infra News: Base surpasses Arbitrum, Helius Webhooks Enables Real-Time Solana Event Monitoring

Monthly DeFi Ecosystem Update by Today in DeFi

Among Large Caps, Solana showed  growth across most metrics in October, though recent declines in token prices have dampened some of its momentum. 

Layer 2s saw a shift as Base surpassed Arbitrum in both TVL and trading activity, now leading among all rollups with robust fees and revenue.

Scroll experienced changes post-TGE due to the drop in activity, while Linea gained traction, likely benefiting from an ongoing airdrop program that has drawn increased interest from traders and farmers.

Ethereum

Ethereum All Core Developers Consensus Call #145 Summary

Pectra Devnet 4 and Testnet Mekong

Pectra Devnet 4 launched successfully, with recent fixes enabling all clients to propose blocks. The public testnet, Mekong, launched on October 31 with 110 nodes and 100,000 validators, running for a few months to showcase Pectra features.

Pectra Devnet 5 Preparations

For Devnet 5, developers are finalizing updates, including validator attestation types (PR #3900), peer request rate-limiting (PR #3767), and execution layer tweaks. Incremental gas fee adjustments under EIP 7742 will be included, with larger changes deferred.

PeerDAS Devnet and Fusaka Upgrade

PeerDAS Devnet 3 was shut down due to a large reorganization. Developers are focused on rebasing PeerDAS on Pectra and likely integrating it into the upcoming Fusaka upgrade, prioritizing PeerDAS as a core feature.

New EIP 7800: Withdrawal Credential Update

EIP 7800, proposed by Lucas Saldanha, would allow validators to update withdrawal credentials without exiting, supporting future smart contract operations. Supported by developers, it may be included in an upgrade after Pectra.

New 3-Slot Finality Protocol Speeds Up Block Finalization

Researchers have introduced 3-Slot Finality (3SF), a protocol that finalizes blocks in three slots with only one voting phase per slot, reducing overhead and slot time. This method shortens confirmation times, making it ideal for financial applications by minimizing risks from arbitrage.

3SF can also be adapted to finalize in two slots with an added voting phase, while modified slashing rules maintain security by preventing conflicting validator votes.

Full DAS Sampling Analysis for Enhanced Data Availability

Leobago’s study on Ethereum’s DAS shows the network can efficiently manage data, ensuring high decentralization and resilience even during major node failures. Validator-proportional custody helps balance data distribution, though coordinated attacks by a 90% dishonest majority remain challenging. Increased data replication and lossy sampling offer some protection but have limitations against large-scale malicious attacks.

Layer 2

Optimism supports ERC-7683 for Crosschain Intents

Optimism has announced support for ERC-7683, the cross-chain intent messaging standard designed to unify liquidity across Ethereum Layer 2s. By standardizing cross-chain interactions as intents, ERC-7683 bridges the Superchain with the broader Ethereum ecosystem, promoting a cohesive and interoperable network. This initiative aligns with Optimism’s vision to reduce cross-chain friction and help Ethereum achieve internet-level scale.

Conduit Account Abstraction for Rollups

Conduit Account Abstraction is designed to enhance user experience on rollups by simplifying onchain interactions. This solution, priced at $500/month, combines Conduit Bundler for handling complex transactions with ZeroDev Smart Accounts for gasless transactions, session keys, and social recovery, following the ERC-4337 standard. Rollups can choose to implement both components or use them individually.

Key features include seamless onboarding via email or social accounts, session keys for uninterrupted usage, flexible gas payments with a Paymaster, and simplified multi-transaction operations. Conduit Account Abstraction makes crypto accessible by reducing onchain friction, helping rollups attract and retain more users with a user-friendly experience.

Solana

Syndica Cloud: our V2 RPC Implementation

Syndica Cloud’s V2 RPC infrastructure for Solana enhances speed, reliability, and control. It includes multi-region support, optimized node hardware, and a reengineered API gateway in Rust. Features like WebSocket Subscription Multiplexing reduce latency by reusing identical subscriptions, and node affinity allows consistent network views by routing sequential requests to the same node. Enhanced real-time metrics provide detailed insights into performance and usage.

The platform offers developer-friendly pricing, with a free tier allowing 10 million RPC calls per month, scalable to options like Scale Mode with 200 million calls and 1TB of data transfer. For enterprises, Hyperscale Mode includes custom infrastructure and dedicated support, unifying Solana infrastructure needs on one platform and enabling developers to scale seamlessly.

Helius: Real-Time Solana Event Monitoring with Webhooks

Helius webhooks enable real-time tracking of on-chain Solana events, supporting up to 100,000 addresses and over 80 transaction types per webhook. Users can adjust monitored addresses dynamically via the API or UI. Rather than managing complex infrastructure, Helius webhooks notify users of specific events such as sales, listings, and swaps by sending updates directly to a designated URL.

Helius offers multiple webhook types, including enhanced transaction webhooks for specific events (like NFT sales), raw transaction webhooks for any transaction, and Discord webhooks for direct channel updates. Automatic event detection covers NFT sales, DeFi swaps, DAO votes, and more, eliminating the need for custom parsers and simplifying event tracking for developers.

Sui

sSUI: Liquid Staking on SUI

Suilend has launched sSUI, the first Liquid Staking Token (LST) on Sui, built using the open-source SpringSui Standard. SpringSui enables instant unstaking for continuous liquidity and reduced depegging risks, a major improvement for liquid staking on Sui, which currently has low adoption compared to other blockchains.

sSUI allows staked assets to be instantly redeemable, mitigating depegging risks even during volatility, as defined by SIP-33. Initial partners AftermathFi and Studio Mirai will leverage SpringSui for their own LSTs. SpringSui has completed an audit by Ottersec, with another from Zellic in progress, ensuring user safety and smart contract reliability.

Aptos

USDT has officially arrived on Aptos Mainnet

Tether is launching USDT on the Aptos Network, making it the first major stablecoin on a Move-powered blockchain. This integration will expand USDT’s availability, with Aptos offering low gas fees and fast transaction processing, potentially supporting both small and large-scale transactions.

Aptos’ DeFi ecosystem, transaction capacity, and low fees may provide a foundation for USDT’s broader reach. By joining the Aptos network, USDT aims to enhance accessibility in digital finance, especially in emerging markets, with performance suited for varied transaction needs.
