Frequently Asked Questions

Good Friend Solution Co., Ltd. is an IT company built on the philosophy of "connecting people and businesses like good friends." Since its incorporation in November 2016, the company started with automated-trading coding tools and has expanded into blockchain, commerce, and AI, building a connected ecosystem where AI, Commerce, and Web3 meet.

It refers to a structure in which every platform shares a single SSO, settlement, and AI core. This is why product names such as HubLink, ShopLink, ActsLink, and IncomeLink all end in "Link" — the members, content, and revenue created in one place carry over as assets for other services, amplifying network effects.

They are organized into three layers. Layer A — Link Commerce (HubLink, ShopLink, GOOD_SHOP, 100Seller Shop, SNS_AUTO), Layer B — Relation & Content (ActsLink, Relation, IncomeLink), and Layer C — Web3 & Finance (Intrai Copilot, Web3 digital assets, EA/Easy Maker). You can find more details on the Services page.

Currently, SNS_AUTO is actively in operation, and ShopLink is running as a core service. HubLink, GOOD_SHOP, ActsLink, IncomeLink, Intrai Copilot, and others are in development (In Dev); we can share their launch schedules and beta participation details upon inquiry.

AI agents handle product listing, customer service (CS), settlement, and content creation on your behalf. The core idea is that multi-agent systems automate repetitive tasks so that even small organizations can operate at the speed of a large platform.

EA Maker (based on MetaTrader) and Easy Maker (based on YesTrader) are the company's founding technology assets. Today they are being carried forward and further developed as the core engine of our next-generation AI trading solution Intrai Copilot and as the foundation of our educational assets. We provide guidance on related adoption inquiries individually.

It covers the design and consulting of RWA (real-world assets), STO (security token offerings), and NFT tokenization, as well as building on-chain trust infrastructure based on our experience in coin development and exchange setup.
