About the Product
Solution: Offer-Hub provides modular infrastructure that allows new and existing marketplaces to integrate non-custodial escrow and crypto payments without building financial logic from scratch.
How the flow works: When a buyer confirms an order on a marketplace, Offer-Hub creates an escrow transaction on the Stellar network. The buyer pays in supported stablecoins, and the funds are locked according to predefined rules such as milestones, time conditions, or approval requirements.
The funds are not held by Offer-Hub or the marketplace. Instead, they remain secured on Stellar under programmable conditions. This removes the need for centralized custody and reduces fraud risk.
Once the agreed conditions are met, the payment is automatically released to the seller. The execution happens directly on the Stellar network, ensuring transparency and finality.
After receiving the funds, the seller can keep the stablecoins or convert them into local fiat currency through integrated on/off ramps, leveraging Stellar’s fast and low-cost settlement layer.
Role of Stellar: Stellar is the core settlement infrastructure of Offer-Hub. It enables near-instant transactions with minimal fees, supports stablecoins to reduce volatility, and facilitates efficient crypto-to-fiat conversion. All escrow logic, fund locking, and release mechanisms are executed on Stellar, making it the foundational layer that guarantees security, transparency, and cost efficiency.
Offer-Hub builds the modular marketplace layer on top of Stellar, while Stellar provides the financial execution layer that powers secure and scalable transactions.
Problem & Solutions
Problem
Marketplaces often struggle with lack of trust between buyers and sellers, high costs and fees from traditional payment and escrow providers, and friction in managing secure transactions; additionally, there is no standard modular infrastructure that allows launching a marketplace with held payments and clear rules without building from scratch or relying on costly centralized systems.
