Definition
Ujrah (أجرة) is the Arabic term for a fee, wage, or compensation paid for genuine work, service, or labour. It is structurally different from riba: riba is a fixed increase paid for the use of money over time; ujrah is paid for a real service provided by the recipient. The ujrah category is the basis for the entire ijarah (leasing) contract structure in Islamic finance — itself one of the most-used contracts in modern halal banking.
Why ujrah matters for crypto
The crypto-relevant case is proof-of-stake (PoS) validation rewards. When a token holder commits their stake to a validator (or runs a validator themselves) and receives newly minted tokens plus transaction fees in return, the question is: are those rewards riba (fixed return on locked capital) or ujrah (compensation for validation work)?
The dominant scholarly position — including positions consistent with AAOIFI's general guidance — distinguishes:
- Pure proof-of-stake validation where rewards represent payment for actual work (signing blocks, validating transactions, providing finality) is treated as ujrah. The validator is providing a network service; the network compensates them. Permissible.
- Lending-style "yield" that pays a fixed interest-like return on locked tokens with no validation work performed by the depositor is not ujrah. The "lock-up" in this case is just a debt structure with the issuer; the return is riba.
- Liquid staking derivatives that hide a riba-like fixed return inside a re-issued token wrapper are typically excluded under the substance-over-form principle.
Why HalalCrypto does not stake on customers' behalf
Even where a particular PoS token's reward structure passes the ujrah analysis, HalalCrypto does not engage in staking on customers' behalf. Reasons:
- Custody risk. Staking typically requires either delegating to a validator (a custody risk) or running validator infrastructure (operational risk we do not take on for customers).
- Lock-up risk. Many staking structures impose unbonding periods that conflict with our ability to execute timely exits per tier risk parameters.
- Classification ambiguity. The ujrah-vs-riba analysis varies per protocol and changes when protocols update their reward formulas. We focus on what we can audit deterministically.
Customers who want to stake their assets after holding them in our system can do so independently after withdrawing to self-custody or a regulated staking service of their choice. We make the analytical framework transparent so that they (or their scholar) can decide.
