Simulation Mode is a persistent “act-as-this-wallet” context. When it is active, Explorer pages render and simulate as the impersonated wallet: contract Read/Write pages auto-fill the From address, wallet pages expose one-click impersonation, and transaction pages let you re-simulate as that wallet. This page covers the Explorer surfaces wired into Simulation Mode. For the session model, balance overrides, state settings, and the Sim Mode panel itself, see the full Simulation Mode documentation.

​
Entering Simulation Mode from the Explorer

There are two entry points:
  • Top bar: click Enter Simulation Mode and pick a wallet and network. The button is available on every Explorer page.
  • Wallet detail pages: an Impersonate button sits between Create Alert and Simulate. It activates Simulation Mode pre-filled with that wallet, with no picker step.
Once active, the top-bar button is replaced with a SIMULATING pill showing the wallet’s identity icon, abbreviated address, and total USD balance. The context follows you across pages until you exit.

Explorer surfaces wired into Simulation Mode

SurfaceBehavior when Sim Mode is active
Contract Read/Write pagesA purple banner indicates Sim Mode is active. The Write button is hidden and Simulate becomes the primary action. The From field auto-fills with the impersonated wallet.
Transaction detailThe Re-Simulate dropdown gains a Re-simulate as [wallet] option, so you can replay any transaction as the impersonated wallet.
Wallet detail pagesThe Impersonate button activates Sim Mode for that wallet directly.
If you open a page on a network different from your active session, a banner offers a one-click Switch Sim Mode to [network]. Read and Write actions are disabled until you switch.

​
Relation to the Simulator

Simulation Mode and the Simulator are complementary:
  • Simulation Mode is a session: simulations accumulate, each run sees the state the previous ones produced, and the wallet context persists across Explorer pages.
  • The Simulator is where you build and run individual simulations and multi-step bundles. With Sim Mode active, the Simulator pre-fills the sender as the impersonated wallet and successful runs append to the session log.
