Dev Release-217

This release expands our Explorer’s market data capabilities, deepens token-level visibility, and hardens transaction flow resilience across the protocol. On the Explorer side, we’re integrated Active ERC20 Address tracking across States and Charts, and improved time-range filtering. On the protocol side, we’re introducing a Relay Node mechanism to keep transaction handling smooth during sync, and standing up a bundler service for ERC-4337 UserOperation flows aligned with Ethereum’s recommended design.

• Surface Active ERC20 Address metrics in both States and Charts.
• Implement relay-forwarding for transactions during node sync.
• Deploy and configure ERC-4337 bundler for UserOperation submission.

• Active ERC20 Addresses: Time-series charts in both States and Charts, with 24h/7d/30d/All filters, offering ecosystem-level visibility into token activity.
• Relay Node Mechanism: Ensures transactions submitted to a syncing node are forwarded to a fully synced peer, preserving continuity without user disruption.
• ERC-4337 Bundler: A backend service for UserOperations, handling validation, batching, and submission to EntryPoint, providing a key building block for account abstraction.

Active ERC20 Address Charts
A new chart series tracks active ERC20 addresses over time and will appear in both the States panel and the Charts section. Users can filter the dataset by 24h, 7d, 30d, or All-time windows. This addition helps developers, analysts, and community members assess network engagement and token adoption with clarity. The charts adapt responsively across screen sizes and align visually with the Explorer’s overall aesthetic.

Relay Node for Transaction Forwarding
Nodes no longer become bottlenecks during synchronization. If a node is behind the chain head, it will forward incoming transactions to its synced peer (the same source it is syncing from) and relay the response back to the origin sender. This design guarantees continuous participation, eliminating transaction failures caused by temporary sync lag and maintaining trust in network throughput.
 

ERC-4337 Bundler Integration
We’ve deployed a bundler service that listens for UserOperation objects in the mempool, validates them, and submits them to the EntryPoint contract. This bundler follows Ethereum’s reference flow, with support for batching and extensible policy layers. It sets the foundation for advanced account abstraction use cases, enabling developers to experiment with innovative wallet experiences and gas abstractions.

App Submission

We’ve submitted the proposed Figma designs for X1 to App Stores for review and acceptance. These updated flows aim to resolve UX and functional issues identified during onboarding and usage testing, covering referral code verification, OTP handling, password validation timing, BDAG display formats, and notification delivery. The refreshed design brings consistency to the user journey and aligns with store acceptance guidelines, positioning X1 for smoother onboarding and improved user experience upon release.

Text Alignment in Contract Data Graphs
On the Contract Data page, the titles “Daily Verified Contract” and “Daily Deployed Contracts” are misaligned. They should be left-aligned to match the approved Figma design. A styling fix is in progress to bring consistency across graph headers.
 

Graph Title Styling Mismatch with Figma
The font size, weight, and color of the graph titles do not align with the Figma specification. Updates are being made to ensure visual parity and maintain design consistency across the Explorer.
 

Graph Hover Tooltip Color
Hovering over data points in Contract Data graphs (and related pages) shows a black tooltip background, which conflicts with the Explorer’s theme. The tooltip style is being corrected to align with the current color scheme.
 

Incorrect Data in 1-Minute Filter of Contract Chart
When selecting the 1-minute filter on the Contract Chart, the displayed results incorrectly show aggregated monthly data instead of minute-level data. Backend queries are being adjusted to deliver the proper granularity.

• Extend market data charts with export and analytics overlays.
• Add per-token “Top Movers” rollups in ERC20 states.
• Benchmark relay-node throughput under heavy sync scenarios.
• Harden bundler monitoring with simulation endpoints and testnet runs.

We’re looking for feedback on chart usability, ERC20 data ranges, and bundler edge cases. Node operators: please report any relay-node anomalies during sync. Developers experimenting with ERC-4337, share test cases to help improve validation and batching performance.

This release is about smoothing the data experience, sharpening token activity insights, and ensuring the network never stalls under sync conditions. With scalable charts, continuous relay mechanics, and a live bundler, we’re paving the way for richer analytics and smarter account abstraction.
