Non-custodial services are platforms or tools that enable users to retain control over their digital assets, such as cryptocurrencies. Unlike custodial services, where a third party holds and manages assets on behalf of the user, non-custodial solutions empower users to maintain full ownership and responsibility for their assets. These services often utilize wallets, decentralized exchanges (DEXs), or protocols that do not require trust in an external entity, thus enhancing security and autonomy.
