Show HN: I built a stablecoin marketplace for digital goods

https://www.stablecoins.club/
1•jameshih•1h ago
Hi HN, I’m James and I built Stablecoins Club, a Craigslist-style marketplace to buy and sell digital goods directly, wallet-to-wallet, on Polkadot Asset Hub. All payments and transaction fees are handled in USDC or USDT, so users never need another token just to cover blockchain fees. The platform is free to use, with no listing fees, no escrow, and no middlemen, providing a simple, direct, peer-to-peer way for creators and buyers to transact.

I’d love to hear your feedback and ideas for features that would make the marketplace even more useful.
