# Arbiter > Policy-first multi-client wallet daemon, allowing permissioned transactions across blockchains ## Security warning Arbiter can't meaningfully protect against host compromise. Potential attack flow: - Attacker steals TLS keys from database - Pretends to be server; just accepts user agent challenge solutions - Pretend to be in sealed state and performing DH with client - Steals user password and derives seal key While this attack is highly targetive, it's still possible. > This software is experimental. Do not use with funds you cannot afford to lose.
