wallet: sign_message: strip whitespaces in GUIs, do not strip in CLI

This commit tidies up how Electrum handles extra spaces around Bitcoin addresses, messages, and signatures when signing or verifying messages. Previously, different parts of the program (desktop GUI, mobile-style GUI, command line) behaved…

wallet.check_sighash: don't assume tx.add_info_from_wallet alrdy ran

This commit fixes a defensive check in the Electrum Bitcoin wallet. Before signing a transaction, Electrum checks whether the transaction uses unusual 'sighash' flags that could allow someone else to move coins unexpectedly. The bug was th…

lnpeer: on_ping: drain out-socket buffer

This change fixes a potential denial-of-service weakness in Electrum's Lightning network peer handling. Previously, when Electrum replied to a peer's 'ping' message, it would add the reply to the outgoing socket buffer without waiting to c…

verifier.py: fix CVE-2012-2459: reject left-sibling duplicates

This commit fixes a known Bitcoin weakness (CVE-2012-2459) in Electrum's light-client verification. Because Bitcoin's Merkle tree duplicates the last hash when a level has an odd number of items, an attacker can craft a block proof that ma…

in GUI mode, only start a limited minimal RPC server

This commit reduces the attack surface of Electrum's built-in remote-control server when running in normal GUI mode. Previously, the RPC server exposed many wallet-related commands; now, in GUI mode on mainnet, it only exposes two safe com…

locale: don't translate string "Electrum", "BIP39"

This commit removes translation markers from two proper names ('Electrum' and 'BIP39') in a wallet setup wizard dropdown. It is a localization/UI consistency fix with no security relevance.

wallet: rpc: manpage: fix example missing `fee_rate` argument

This commit fixes a typo in the documentation example for the `send` RPC command. The example was missing a placeholder for the `fee_rate` argument, which caused the example command to be interpreted incorrectly and produce an error if cop…

transaction: tx_from_any: rm all whitespaces from str, none from bytes

This commit fixes a bug in how Electrum reads transaction files. Previously, the program would strip whitespace from both text and raw binary transaction data. For binary data, this is dangerous because a byte that looks like a space or ne…

transaction: psbt.from_raw_psbt: clarify hex input must be str

This is a tiny code cleanup in Electrum's transaction handling. The change removes a check that accepted bytes for a hex-encoded PSBT, because Python's bytes.fromhex() only accepts strings anyway. The commit message explicitly says there i…
