Jibse 🏠

Jibse helps tenants and owners make a worry-free lease contract without knowing each other.

🙋‍♀️ As an owner,

• I can post a place I want to rent out at any price and for any period I want using cryptocurrency.
• I can check the transaction histories of applicants to prevent fraud.
• I can easily check the payment status of current tenants.

🙋‍♂️ As a tenant,

• I can ensure if the owner is a trustworthy person by reading reviews of rooms.
• I can pay a deposit and rent using cryptocurrency.
• I can get evidence on the network without having to write a separate contract.
• I can set up auto-payment.

Inspiration ⚡️

We are foreigners who have recently settled in Toronto. It was unnecessarily difficult for us to find a place to rent because of :

• Uncertain identity of owners on existing platforms like Kijiji, Craigslist
• Shortage of local currency holdings
• Lack of proofs to prove identities such as credit scores, income, and reference in Canada

What this platfrom offers

• Transparency and reliability of both owner and tenant by publishing all transactions into the Ethereum network
• Convenience and practicality by using cryptocurrencies especially paying a deposit from overseas before moving into a country
• Equality by giving the "ownership" of payment history to the user on Jibse to determine reliability instead of relying on bank credit score, income proof, reference, etc
