Arkham unveils Transaction Explorer V2 with enhanced swap detection

Reading a complex DeFi transaction has always felt a bit like trying to decode a restaurant receipt written in a foreign language. One swap routed through three aggregators, four intermediate tokens, and six smart contracts later, you’re still not sure who paid for what. Arkham Intelligence’s Transaction Explorer V2, launched on September 21, 2026, is a direct attempt to fix that.

The upgrade rebuilds Arkham’s existing transaction pages from the ground up, adding detailed trade and swap data across all supported chains. Where earlier versions left users to piece together multi-hop routes manually, V2 collapses that complexity into something readable.

What actually changed

The headline feature is swap detection treated as a first-class data type. Arkham now identifies swaps executed across major decentralized exchanges and aggregators and surfaces them the same way a centralized exchange would display a trade: with the swapped tokens, pricing, size, and counterparty all in one place under a dedicated section.

The second major change is netting. Multi-hop aggregator transactions, the kind where a swap routes through several intermediate tokens before arriving at the final output, are collapsed into a single line item per token per address. Previously, each hop appeared as a separate event, making it genuinely difficult to understand the net economic outcome of a single user action.

Users can also input any transaction ID directly into Arkham’s platform and pull up the corresponding V2 view immediately. That’s a small quality-of-life addition, but it means anyone can test the new interface against their own transaction history without navigating through a wallet profile first.

The updated interface also surfaces net balance changes per address within a transaction, giving researchers a fast read on who ended up with more and who ended up with less after a given on-chain event.

Why this is harder than it sounds

Arkham’s approach, treating the swap as the atomic unit of analysis rather than the individual contract call, brings the user experience closer to what traders are used to on centralized platforms. The goal isn’t to hide the underlying complexity; it’s to make the economically meaningful summary immediately visible without burying it under raw event logs.

Arkham has been building toward this incrementally. The platform introduced a swaps panel in 2023, giving users an early version of swap-level visibility. In early 2025, it added AI-driven transaction summaries, which narrated what a transaction did in plain language. V2 synthesizes those two threads into a structured, data-rich interface rather than a narrative one.
