Summary

This PR completes Milestone 3: Documentation of the CoW Grants Program RFP: CoW Protocol Playground Block Explorer Integration proposal by CoBuilders.

Documentation Strategy

Most of the technical documentation for this integration was delivered inline with the implementation in M1 and M2:

Milestone Documentation Delivered
M1 (#4000) README sections for Sourcify configuration, contract verification, component table updates
M2 (#4077, cowswap#6774) Environment variable documentation in .env files, JSDoc comments in source code

This PR adds the remaining user-facing documentation: a practical guide on how to use Otterscan for transaction inspection and debugging.

Changes

Adds a "Using Otterscan" section to the playground README covering:

  • How to access and use Otterscan (http://localhost:8003)
  • Inspecting transactions (overview, traces, logs, gas profiling)
  • Debugging failed transactions with trace analysis
  • Example workflow: Tracing a CoW Swap settlement
