dflow-trading

dflow-trading is a cursor rule for coding agents from helius-labs/core-ai. It costs 0 tokens per session (337 once invoked), scanned A, original, MIT.

A set of development rules for integrating the DFlow trading API with Solana applications. DFlow provides swaps and prediction-market trades on Solana, a blockchain network.

In plain words
What is it for?
Use it when implementing DFlow trades, backend proxies, atomic token amounts, order-status polling, prediction-market checks, maintenance handling, and transaction submission.
Why use it?
It prevents common integration errors such as sending browser requests without a backend, using the wrong token units, skipping market or identity checks, and mishandling asynchronous orders.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

dflow-trading scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 4d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

What it actually says

CORS & Backend Proxy

  • ALWAYS proxy DFlow Trade API calls through a backend for web apps — DFlow does not set CORS headers, so direct browser calls will silently fail
  • Dev endpoints are for testing only — do not ship to production without a DFlow API key from pond.dflow.net/build/api-key

Amounts

  • ALWAYS use atomic units for amount1_000_000_000 for 1 SOL, 1_000_000 for 1 USDC; passing decimal values will produce incorrect trades

Async Order Handling

  • ALWAYS poll /order-status for async trades — prediction markets and imperative trades with executionMode: "async" do not return a transaction synchronously
  • ALWAYS check market status === 'active' before submitting prediction market orders
  • Handle the Thursday 3–5 AM ET maintenance window for prediction markets

KYC

  • ALWAYS check Proof KYC status before prediction market trades — gate at trade time, not at browsing time

Transaction Submission

  • ALWAYS submit DFlow transactions via Helius Sender — never raw sendTransaction to standard RPC
  • DFlow /order with priorityLevel handles priority fees and Jito tips automatically — do not add duplicate compute budget instructions
  • For custom (non-DFlow) transactions, follow the standard Sender rules: setComputeUnitPrice + setComputeUnitLimit + Jito tip

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
