README shows base-mainnet withdrawal commands without required --fault-proofs flag

[mssystem1]

The README contains a “Without Fault Proofs” flow that uses --network base-mainnet without the --fault-proofs flag.

However, the current CLI configuration marks base-mainnet as a fault-proofs network. In main.go, base-mainnet has faultProofs: true, and the CLI exits with “Fault proofs are required on this network, please provide the --fault-proofs flag” when --fault-proofs is not provided.

As a result, users who copy the README command for base-mainnet will get an error instead of proving or finalizing a withdrawal.

Steps to reproduce:

1. Open README.md

2. Go to the “Without Fault Proofs” section

3. Notice the command shown for proving a withdrawal:

   withdrawer --network base-mainnet --withdrawal --rpc --private-key

4. Run the command as written

5. Open main.go

6. Notice that the networks map sets base-mainnet with faultProofs: true

7. Notice that if --fault-proofs is not provided for a network where faultProofs is true, the CLI exits with:

   Fault proofs are required on this network, please provide the --fault-proofs flag

8. The README command therefore fails for base-mainnet

[mssystem1]

Expected behavior:

The README should not show base-mainnet commands without --fault-proofs.

Expected behavior should be one of:

1. Remove or clearly mark the “Without Fault Proofs” flow as legacy / only for custom networks that do not use fault proofs
2. Update the base-mainnet examples to include --fault-proofs
3. Use a non-fault-proof custom-network example in the “Without Fault Proofs” section instead of base-mainnet

[mssystem1]

Suggested fix:

Update the README commands in the base-mainnet flow from:

withdrawer --network base-mainnet --withdrawal --rpc --private-key

to:

withdrawer --network base-mainnet --withdrawal --rpc --private-key --fault-proofs

And for Ledger:

withdrawer --network base-mainnet --withdrawal --rpc --ledger --fault-proofs

Alternatively, move base-mainnet entirely out of the “Without Fault Proofs” section, because the current code requires fault proofs for base-mainnet.
