CLASS / BOUNDARY
Map the responsibility shift before choosing a platform.
An exchange account and a self-custody wallet answer different tasks and fail through different control paths; they never share one proof board.
Custodial exchange
The rig follows product, contracting entity, custody, account controls, funding, execution and withdrawal. The operator can usually intervene in account access.
The panel text states the applicable control and output boundary.
Self-custody wallet
The rig follows key creation, recovery, signing, service dependencies and software distribution. User error or key loss can be irreversible.
The panel text states the applicable control and output boundary.
Risk transfer
Moving assets changes the party and mechanism that can fail; it does not remove risk.
The panel text states the applicable control and output boundary.
Board separation
Exchange documentary axes and wallet boundary axes remain separate, with no cross-category winner or score.
The panel text states the applicable control and output boundary.
Task definition
Record intended action, amount at risk, holding period, recovery plan and tolerable failure before selecting a category.
The panel text states the applicable control and output boundary.
