Exchange or self-custody wallet: who must do what?
An exchange normally controls an account and hosted keys. A self-custody wallet gives the user signing control. Moving between them changes responsibility, not the existence of risk.
What is an exchange account?
A company provides a custodial service under terms. It may verify identity, restrict the account and control withdrawals. Check the exact company, asset path and complaints route.
What is a self-custody wallet?
Software lets the user control signing credentials. Recovery, permissions, malicious transactions and software distribution become central responsibilities.
Which one is safer?
There is no universal answer. An exchange can fail or restrict access; a wallet user can lose recovery material, approve a harmful request or install compromised software.
Why are there two comparison tables?
Exchange questions concern companies, custody and exit. Wallet questions concern keys, recovery, signing and software. Combining them would hide the real failure paths.
What should I decide first?
Write down the job, amount at risk, holding time, recovery plan and what failure you can handle. Then choose the category before choosing the brand.
