What is Self-Custody in Decentralized Finance?
Self-custody means that the user alone holds the private keys to their digital assets, thus having full control without an intermediary. In the Islamic context, this aligns with Sharia principles of ownership, where no third party holds or controls someone else's wealth without permission.
Difference Between Self-Custody and Third-Party Custody
In third-party custody (e.g., centralized exchanges), users entrust their keys to another entity, risking bankruptcy or hacks. Self-custody makes the user solely responsible, ensuring transparency and avoiding reliance on potentially non-Sharia-compliant institutions.
Sharia Benefits of Self-Custody
Sharia-wise, self-custody fulfills several principles: (1) actual ownership of the asset, (2) absence of riba (interest) and gharar (excessive uncertainty) as transactions are direct, (3) ability to return surplus in financing deals. It also aligns with the rule 'al-kharaj bi al-daman' (profit accompanies liability).
Application of Self-Custody in Islamic DeFi
On platforms like Qist, self-custody means the buyer fully owns the asset (e.g., NFT or token) until the value is paid. The seller cannot reclaim the asset unless the buyer defaults after the grace period. This ensures fairness and reduces risk.
How Qist Implements This
Qist adopts self-custody via immutable smart contracts on Base. The user retains their private keys, and the contract transfers ownership only when conditions are met. No central authority controls assets, enhancing transparency and Sharia compliance.
