Honest question, since willing naman karamihan satin na ibalik yung funds especially if yung wallet or address na nasend ito matratrace sa account natin dito, bakit kailangan pa natin mag-require ng signed message kung isesend lang din naman sa same wallet address? ...bakit pa natin irerequire ng signed message unless sa ibang address ipapasend.
It's one of the options para ma verify na siya nga may ari ng address where the funds came from. Daming magaling mang uto online lalo na sa crypto space kaya na uso ang social engineering in crypto scams at nakapag result ng $ million of loses.
At bakit hindi agad i send back sa sending address ng transaction for refund kase hindi natin alam if own wallet address ang gamit pag send, minsan exchange ang gamit ng iba, at base sa exchanges system ng sending tx, its from exchange hot wallet address then send to withdrawal address ng users which is multiple sending ang nagaganap. If ise-send back natin dun sa sending address for refund ay malamang sa exchange ma si-send yung fund at hindi sa mismong owner.
One of the best identifiers or ownership yung signed message, pero, in this case, what if someone is claiming na sa kanila yung address na yun at pinapasend back lang. Especially, for example, may nagopen ng topic dito sa forum na nagkamali sya ng send ng crypto sa address at pinapabalik sa same address na pinanggalingan.
ie.I mistakenly sent my crypto on this address *your address*, kindly send it back on the same address it came from.
No social engineering or possible scams since return to sender lang. Hindi ko lang makita yung point ng signed message, on this scenario.
Usual, usecase kasi signed message dito sa forum ay ownership ng isang forum user sa isang address kaya gamit na gamit ito sa lending, escrow and account retrieval.
Gets ko yung sa exchange wallet address, which is dapat talaga hindi natin isend back sa same wallet address without notice.
