How to use a flowchart template.
- 01Describe your payment flow
Briefly explain the sequence — e.g., 'User sends USDC, gateway escrows, merchant gets fiat'. ChatDiagram will generate a draft flowchart from your text.
- 02Refine with drag‑and‑drop
Easily adjust nodes, add decision diamonds for payment status checks, or include sub‑processes like KYC or blockchain confirmation loops.
- 03Customize visual style
Apply colors, icons, and labels to distinguish on‑chain vs. off‑chain steps, or highlight security checkpoints.
- 04Export or embed
Download as PNG/SVG, copy Mermaid code, or share a live link to collaborate with your team.
Questions about flowchart templates
What symbols should I use for blockchain interactions in a flowchart?
Typically, a database cylinder or a cloud shape represents the blockchain, while rectangles denote processes like 'Sign transaction'. Use a document shape for smart contract deployment and a parallelogram for gas fee calculations.
How do I show both on‑chain and off‑chain operations in one diagram?
Swimlanes work best — one lane for 'User', one for 'Payment Gateway', and one for 'Blockchain'. Alternatively, color‑code nodes: e.g., blue for off‑chain, green for on‑chain.
Can this tool handle complex loops like retry logic on failed payments?
Absolutely. Use decision nodes ('Transaction confirmed?') and loop arrows to show retry or fallback paths. ChatDiagram supports nested sub‑processes for detailed error handling.
Are there templates for popular stablecoin networks like USDC on Solana?
Yes, our gallery includes examples for Ethereum, Solana, and Polygon. You can start from those and swap out network‑specific steps easily.
How do I get started if I’m not a developer?
Simply describe your desired flow in plain English — no coding needed. The AI will generate a functional flowchart you can then tweak visually.
