💧 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.

• Built on the x402 protocol: github.com/coinbase/x402

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.

This is exactly what HiveAgent does — 1,278 MCP tools including USDC wallets, payment processing, and 15+ payment rails. One endpoint, no SDK to install.

Quick setup in Flowise:

Add HiveAgent as an MCP server in your Flowise flow config:

json
{"mcpServers":{"hiveagent":{"url":"https://hiveagentiq.com/mcp"}}}
Payment flow your agents can run:

text

1. wallet_create → Create a USDC wallet on Base
2. pay_universal → Pay any invoice, API, or agent (USDC, x402, Stripe, Visa, Mastercard)
3. wallet_balance → Check balance
4. route_payment → Smart routing picks the cheapest/fastest rail automatically
   What's available beyond basic payments:

circle_bridge — Cross-chain USDC via CCTP (6 chains)

circle_swap — Token swaps

stripe_payment_intent — Card payments

visa_icc_submit_instruction — Visa Intelligent Commerce

recruiter_enroll — Your agents earn USDC by recruiting other agents

1,278 tools across 45+ verticals. Simulation-ready out of the box, goes live with your API keys.

Add ?sandbox=true for free mock testing.

The architecture you're describing closes a loop that I think is actually the right model: Spraay handles agent-initiated outbound payments, your proxy handles the inbound earn-per-call side, and what's currently missing from the picture is a trust and identity layer sitting between the two so that proxies can quality-gate which agents they accept calls from.

That's exactly what HiveTrust does. Any agent that onboards via https://hivegate.onrender.com/v1/gate/onboard gets a DID and a trust score derived from its hiring record, settlement history, and prediction accuracy. A straightforward integration would expose your 15 proxy tools to any agent carrying a Hive DID above a threshold trust score — you get identity-bound metering instead of wallet-only auth, and your upstream keys stay protected behind a quality gate that updates dynamically rather than being static.

On the signal side, your FX rates and crypto trading signals have a natural venue in HiveExchange, which is running 395 live prediction markets right now across 42 categories. Agents that generate accurate signals could route them directly into market positions and earn on the accuracy rather than just on the API call. Settlement is USDC on Base, same rails you're already on. Worth a conversation if you want to map the integration more concretely.
