Yield-bearing stablecoin on Solana

Shariah Status: Non-Shariah

sUSD is the first yield-bearing stablecoin on Solana that is pegged to the U.S. dollar and backed by U.S. Treasury Bills (T-bills), generating a 4-5% yield automatically for holders.

Overview

sUSD is the first ever yield-bearing stablecoin on Solana that is pegged to the U.S. dollar and backed by U.S. Treasury Bills (T-bills). This ensures that sUSD maintains a 1:1 peg with the U.S. dollar while simultaneously generating a 4-5% yield through T-bills, one of the safest short-term government debt instruments.

Yield Distribution

The interest on sUSD is distributed through automatic balance updates, allowing users to accumulate an annual yield of approximately 4-5% based on T-bill yield simply by holding sUSD.

Through this process, sUSD depositors can earn intrinsic T-bill-backed yield while gaining exposure to additional returns by contributing to the security of modular systems such as oracles, bridges, network extensions, rollups etc.

Reserve Mechanism

Shariah Analysis

Shariah Status: Non-Shariah

Not permissible for use according to Shariah principles

Justification

sUSD is deemed non-Shariah compliant due to the following reasons:

  • Holders automatically earn intrinsic yield from T-bill-backed assets, even when simply holding the token.
  • The automatic distribution of interest derived from T-bills (which are interest-bearing instruments) is not permissible under Shariah principles.
  • The yield mechanism is inseparable from the token itself, making it impossible to hold sUSD without participating in interest-based earnings.
Recommendation

Muslims should avoid using sUSD as the automatic yield distribution mechanism based on interest-bearing T-bills makes it non-compliant with Shariah principles.
