ppc default fee rate update
What changed, and why it matters
This commit increases the default Peercoin transaction fee rate from 5000 to 10000 satoshis per kilobyte and adds a test to verify the new value. It is a routine fee policy adjustment, not a security fix. The only code change besides the fee value is a minor formatting/indentation cleanup in an unrelated address derivation block.
No security action required. Review as a normal fee policy update; ensure the new rate aligns with current Peercoin network conditions and user expectations.
Security signals we found
No strong security signals were identified.
Evidence from the diff
The change updates defaultFeeRate in lib/wallets/crypto_currency/coins/peercoin.dart from BigInt.from(5000) to BigInt.from(10000). A new unit test test/wallets/peercoin_policy_test.dart asserts the new default. The diff also reformats a P2WPKHAddress.fromPublicKey call by removing unnecessary line breaks. There is no evidence of a vulnerability, bug fix, or security-relevant behavior change.
