💧 Spraay — Give your Flowise agents crypto payment superpowers (no code, 5 min setup)

[plagtech]

Hey Flowise community! 👋

I built a set of tools that let your Flowise agents send USDC crypto payments across 16+ blockchains. No code required — you can set it up in about 5 minutes using MCP.

What it does

Your agent gets the ability to:

• Send payments — pay one person or a hundred at once
• Check balances — "how much USDC is in this wallet?"
• Get token prices — "what's ETH worth right now?"
• Works on Base, Ethereum, Solana, Stellar, XRP Ledger, and 11 more chains

Think of it like giving your AI agent a Venmo account, but for crypto.

Easiest setup (MCP, no code)

1. Open your chatflow with an Agent node
2. Add a Custom MCP tool
3. Set transport to Streamable HTTP
4. URL: grab it from Spraay MCP on Smithery
5. Click Refresh Available Actions — 60+ tools load automatically

That's it. Ask your agent "Send 10 USDC to 0x1234..." and it just works.

Also works as Custom Tools

If you prefer adding individual tools manually, the repo has copy-paste Custom Tool configs with the input schemas and JavaScript functions ready to go.

Would love any feedback. If there's interest I'm happy to submit a PR to add these as built-in Flowise tool nodes too.
