# ✏️ Flow and Design

BlockBolt is **live on the Sui Network**, utilizing **Move-based smart contracts** to power transaction execution, token transfers, and secure payment verification. The protocol is architected for **modularity, scalability, and full decentralization**, enabling seamless interactions between merchants, wallets, and the blockchain — with **no intermediaries involved**.

***

**📦 Merchant SDK Architecture**

Visualizes how merchants interact with the protocol through a streamlined SDK that handles transaction requests, QR generation, and blockchain communication.

***

**🔐 Wallet SDK Architecture**

Details how wallet applications independently validate and interact with the protocol, signing transactions without ever connecting directly to the merchant.

**🛍️ Merchant Website User Flow**

Outlines the entire payment journey from the merchant side — from QR generation to transaction status monitoring.

**👤 Customer User Flow**

Depicts the customer journey from scanning a QR code to transaction completion — all without connecting a wallet to a website.
