Coastal24 Wire Transfer - Is it a Scalable Solution or a Risky Gamble?

[MichaelEli]

I'm particularly fascinated in understanding how this service handles multi-signature wallets. If it's reliant on a one account to authorize transactions - is that a vulnerability that needs to be addressed or mitigated, taking into consideration the potential for fraud and manipulation? What safeguards are likely in place to shield from unauthorized access or misuse?
