Self-custody

The individual's holding of their own cryptographic keys, with no custodian, a founding trait of crypto that renders it uninsurable.

Definition

Self-custody is the individual's sovereign holding of their own cryptographic keys, with no custodian, one of crypto's two founding promises alongside irreversibility. Yet it is precisely this trait that renders the asset uninsurable, for it removes the professional guardian whose security the insurer could audit, its cold-storage ratios, its multi-signature schemes, its physical security. Faced with an individual holding their own keys, the insurer can verify neither the quality of the backup, nor the absence of negligence, nor even the reality of the declared loss. The truer the holder is to the decentralized ideal, the less insurable they are, and crypto is insurable only by de-crypting it.

Example

The market does not insure cryptoassets, it insures the guardians, and the self-custodied individual, the purest embodiment of the crypto ideal, remains outside the insurance market.
