Agoric Swingset Contract Explorer

Join the community of open-source builders at Agoric!


A publicly accessible Agoric chain explorer which exposes detail at the Agoric VM level, in particular:
  • Basic Transactions. Cosmos side + Swingset transactions (contract calls)
  • Contract viewer including interacting with the contract
  • List contract facets
  • List assets including ERTP assets
  • All Swingset based queries


The Agoric chain is supported by several Cosmos-level block explorers. However, these do not do a good job of providing detail on activity that occurs inside the Agoric VM (aka Swingset). This bounty is to provide an explorer that would detail Agoric VM activity. Note: if you need assistance with thinking through the design of this bounty, resources will be provided.

Acceptance Criteria

Bounty acceptance will be based on:
  • Functionality in description is provided
  • Plan reviewed with Agoric team
  • Demo of functionality in page that could be deployed as a webapp
  • Be thoroughly documented, including clear instructions on how to use it, its dependencies, and any configuration options.
  • Include a short video demonstrating basic usage scenarios
