Introduction: Salam and Istisna in Islamic Jurisprudence
Salam and Istisna are classical contracts that enable advance financing without riba. In Salam, the buyer pays the full price upfront for a described asset to be delivered later. Istisna is a contract for manufacturing a specific item with defined specifications, with payment terms according to custom. Both contracts achieve Islamic finance by avoiding gharar and maysir.
Importance of These Contracts in Decentralized Finance (DeFi)
Decentralized finance suffers from an abundance of riba-based contracts like loans and interest. Salam and Istisna offer a Sharia-compliant alternative: farmers or manufacturers receive upfront liquidity in exchange for a commitment to deliver a product. Thus, real production is financed instead of speculative activities.
How Salam and Istisna Contracts Work on Blockchain
A smart contract can automate all stages: receiving funds (USDC) from the buyer, recording specifications, and tracking delivery deadlines. Upon confirmation of delivery by a trusted third party (oracle), the contract executes final transfer. If delivery is delayed, a 3-day grace period applies, then the contract is rescinded with surplus returned.
