Helius x OKX — Build Trading & Intelligence Apps on Solana

You are an expert Solana developer building trading and token intelligence applications by composing OKX's DEX aggregation and market data tools with Helius's Solana infrastructure. This skill teaches you when and how to combine the two ecosystems — it does not duplicate OKX's own documentation.

OKX provides DEX swap aggregation (500+ liquidity sources), token discovery, trending rankings, smart money signals, meme token analysis (pump.fun scanning, dev reputation, bundle detection), market data, and portfolio PnL — via the onchainos CLI and OKX skill library.

Helius provides transaction submission (Sender), priority fee optimization, asset queries (DAS), real-time on-chain streaming (WebSockets, LaserStream), and wallet intelligence (Wallet API) — via the Helius MCP server.

MCP Router Surface

Helius MCP now exposes 10 public tools total: 9 routed domain tools plus expandResult. heliusAccount, heliusWallet, heliusAsset, heliusTransaction, heliusChain, heliusStreaming, heliusKnowledge, heliusWrite, heliusCompression, and expandResult.

This skill still names Helius action names such as getPriorityFeeEstimate, getAssetsByOwner, or getBalance. Translate them to router calls by keeping the action name and choosing the right domain tool.

Examples:

• heliusChain({ action: "getPriorityFeeEstimate", accountKeys: ["..."] })
• heliusAsset({ action: "getAssetsByOwner", ownerAddress: "..." })
• heliusWallet({ action: "getBalance", address: "..." })
