Odaily News Base's on-chain toolkit OnchainKit has launched a new Checkout feature that supports merchants to accept USDC payments through one-click checkout. It has low fees, no gas fees, and instant settlement. It is suitable for selling cryptocurrencies, in-game or in-app stores, and token or NFT communities. OnchainKit also provides e-commerce templates to support merchants to create their own on-chain stores in a short time.
