Trustless Deals, Guaranteed Results.
The problem Etharis solves
Etharis is a smart contract escrow infrastructure for Indonesia's sponsorship marketplace, eliminating fraud risks and payment delays between Brands (especially SMEs) and Content Creators.
-
The Problem
The Indonesian creator economy faces a critical trust crisis:
-> Creators experience rampant payment delays and ghosting, working without effective contract guarantees
-> Brands bear financial risk if content doesn't match the brief or gets deleted after payment
-> Micro-deals (< Rp 5 Million) are underserved by existing agency/platform solutions due to high costs -
The Solution
Etharis functions as an "Automatic Notary" using smart contracts as a trustless escrow mechanism:
-> Guaranteed Funds: Brand funds are converted to IDRX stablecoin and locked on-chain immediately after Rupiah payment
-> Assured Results: Funds only release when contract conditions are verified, ensuring creators get paid and brands get content
-> Zero Crypto Friction: Users interact with email/password login - blockchain complexity is completely hidden
Challenges I ran into
