`invalid_exact_evm_transaction_simulation_failed`

The facilitator simulated the transfer and it failed for a reason it could not identify.


Reported by	the facilitator, during verify
Usually fixed by	the buyer or the seller, depending on the cause

Cause

The simulated transferWithAuthorization call reverted, and the follow-up checks (balance, token name and version, nonce) did not explain why.

Fix

Retry once; a transient RPC problem can cause this.
Check the token is not paused and neither address is blocked by the token issuer.
Check the asset address and network in the quote are correct.
