Self-Custody

Self-custody is the practice of maintaining direct control over one's digital assets by managing the private keys required to authorize transactions on a blockchain. Unlike custodial arrangements where a third party holds funds on a user's behalf, self-custody ensures that the user is the sole entity capable of initiating transfers or interacting with smart contracts.

This is achieved through hardware wallets, cold storage, or software applications that keep keys offline and secure from external hacks. The primary benefit is the elimination of counterparty risk, as the user does not rely on the solvency or operational integrity of an exchange.

However, this also places the full burden of security and recovery on the individual, as lost keys result in the permanent loss of assets. It is a foundational requirement for true financial independence within the cryptocurrency ecosystem.
