1.What is the current problem
With the advancement of Filecoin Onchain Cloud (FOC), PDP and Filecoin Pay are gradually becoming important on-chain service and payment infrastructure components within the Filecoin ecosystem. However, at present, the on-chain activities related to these protocols are still presented in a fragmented manner within general-purpose blockchain explorers and lack sufficient semantic expression, making it difficult for users to clearly understand their operational status, invocation relationships, and execution results from a single unified entry point.
On one hand, at the FEVM transaction level, there are cases where a parent call is displayed as successful while its subcalls actually fail, and the explorer fails to accurately present the real execution state, which can easily lead to misjudgments by exchanges, developers, or integrators. On the other hand, at the PDP and Filecoin Pay level, relevant data is scattered across different tools or low-level data interfaces, and general-purpose explorers such as Filfox lack structured and traceable runtime views and service-level representations.
2.Why this problem matters
Blockchain explorers are the most fundamental and most widely used trust entry points within the ecosystem. For developers, service providers, exchanges, and ecosystem observers, whether they can accurately judge transaction execution results, verify whether services are actually running, and understand the relationship between payment behaviors and service behaviors directly affects system integration, security assessment, and ecosystem collaboration efficiency.
As FOC-related services move toward broader adoption, if these on-chain activities remain in a state of being “hard to see” and “hard to verify” within explorers for a long time, this will not only increase usage and integration costs, but also weaken the ecosystem’s overall understanding of new on-chain markets and services, thereby affecting adoption speed and trust foundations.
3.Why it has not been well addressed so far
At present, visualization and data presentation for PDP and Filecoin Pay mainly rely on specialized tools or Subgraph-based dashboards. While these tools are very effective in specific usage scenarios, they cannot fully replace the role of general-purpose blockchain explorers in providing a unified entry point, contextual linkage, and expressive execution semantics.
At the same time, existing explorers focus more on basic transaction and Actor information display, and still lack targeted parsing and presentation capabilities for FEVM subcall execution states, FOC service-level behaviors, and the on-chain operational relationships of PDP and Filecoin Pay. These issues cannot be resolved at the level of a single protocol alone, but instead require systematic supplementation and optimization of data structures, execution semantics, and presentation methods at the explorer level, which is why they have remained insufficiently addressed for a long time.
