The Problem

$3.4 billion sitting idle, earning nothing for renters

When Australians rent, they hand over 4 weeks of rent as a bond — held by a state government board for the entire tenancy. That money earns zero yield for the tenant.

When they move out, the bond takes 2–6 weeks to return. Disputes drag through bureaucratic processes stretching to months. In Australia's rental crisis, where tenants are already financially stretched, this is a real, daily pain.

How It Works

Six steps, zero middlemen

1
Connect walletsTenant and landlord both connect Phantom / Backpack to the RentBond dApp
2
Deposit bondTenant deposits bond in AUDC → locked in escrow smart contract with lease end date
3
Earn yield during tenancyBond deployed to low-risk Solana yield protocol (4–6% APY) — tenant earns, landlord retains full security
4
Vacate + mutual sign-offBoth parties sign digital checkout — mutual approval triggers instant release + accrued yield to tenant
5
Dispute resolutionEither party triggers a licensed inspector oracle (2-of-3 multisig) — reviews photos, signs resolution
6
Fees from yieldProtocol fee covered by a small % of yield earned — tenants pay nothing upfront

Why Now

Four tailwinds converging

💸
AUDC is live

AUD stablecoin exists and is liquid — the rails are ready.

Solana economics

Sub-cent transactions make this viable at tenant scale.

🏚️
Rental crisis

Australia's rental crisis is front-page news. Political will for reform is real.

Execution Potential

MVP scope: one weekend on devnet

Two wallets. USDC proxy for AUDC. Mock oracle for disputes. Fully functional end-to-end in a hackathon window — then iterate to mainnet with a property manager pilot partner in Sydney.

Early distribution: Partner with 1–2 Sydney property managers for a pilot. Superteam AU members who rent → first 100 users. Media angle writes itself: "Aussie builders give renters their money back in seconds."

Built for Australia.
Ready for the world.

Real problem. Every judge in the room has rented. Instantly understandable, technically justified, credible path from hackathon to global protocol.
