To uncouple the RPCs from the global option, they now have a + hardcoded default for the maximum transaction fee, that can be changed for + both RPCs on a per-call basis with the `maxfeerate` parameter. The + `allowhighfees` boolean option has been removed and replaced by the + `maxfeerate` numeric option. diff --git a/src/init.cpp b/src/init.cpp index 0898d0ff25..6564ce5b9a 100644 --- a/src/init.cpp +++ b/src/init.cpp @@ -500,7 +500,7 @@ void SetupServerArgs() gArgs.AddArg("-mocktime=<n>", "Replace actual time with <n> seconds since epoch (default: 0)", true, OptionsCategory::DEBUG_TEST); gArgs.AddArg("-maxsigcachesize=<n>", strprintf("Limit sum of signature cache and script execution cache sizes to <n> MiB (default: %u)", DEFAULT_MAX_SIG_CACHE_SIZE), true, OptionsCategory::DEBUG_TEST); gArgs.AddArg("-maxtipage=<n>", strprintf("Maximum tip age in seconds to consider node in initial block download (default: %u)", DEFAULT_MAX_TIP_AGE), true, OptionsCategory::DEBUG_TEST); - gArgs.AddArg("-maxtxfee=<amt>", strprintf("Maximum total fees (in %s) to use in a single wallet transaction or raw transaction; setting this too low may abort large transactions (default: %s)", + gArgs.AddArg("-maxtxfee=<amt>", strprintf("Maximum total fees (in %s) to use in a single wallet transaction; setting this too low may abort large transactions (default: %s)", // TODO move setting to wallet CURRENCY_UNIT, FormatMoney(DEFAULT_TRANSACTION_MAXFEE)), false, OptionsCategory::DEBUG_TEST); gArgs.AddArg("-printpriority", strprintf("Log transaction fee per kB when mining blocks (default: %u)", DEFAULT_PRINTPRIORITY), true, OptionsCategory::DEBUG_TEST); gArgs.AddArg("-printtoconsole", "Send trace/debug info to console (default: 1 when no -daemon.
