Simulation, Funding, and Sending
These steps happen after the transaction is built.
TX Simulator
Simulation checks whether the transaction can execute. The button that starts it reads Run Simulation.
It can help detect:
- Wrong address
- Wrong network
- Missing balance
- Contract revert
- Gas issue
- Unsupported flow
If Simulation Succeeds
If simulation succeeds:
- Check the summary.
- Make sure the action looks expected.
- Press Proceed to Fund Donor.
If Simulation Fails
Do Not Send
Do not send blindly.
Check:
- Selected network
- RPC
- Donor address
- Recipient address
- Balances
- Private keys entered
- Whether the selected action is supported
Sometimes a manual override may be used, but only if you understand the error.
Fund Donor
The Fund Donor step shows how much funding is required.
The donor usually needs funds for:
- Estimated Gas Cost
- Native Value to Send, if the flow sends native currency
- Native Service Fee, if there is one
- A buffer for gas price changes
The panel adds these up as Total to Fund.
TX Sender
The TX Sender step broadcasts the transaction.
Before pressing Send Transaction, check:
- Network
- Transaction type
- Donor address
- Recipient address
- Expected action
- Gas/funding summary
- Simulation result
After sending, wait for the tx hash and final status.
Once the transaction is confirmed, the send controls also offer Erase donor wallet, which retires the donor and reloads the page — see How to Erase the Donor Wallet.
If Sending Fails
Save the error and tx hash if there is one.
Check whether the transaction was actually broadcast. Sometimes a UI error does not mean nothing happened on-chain.
