This skill still names Helius action names such as `getPriorityFeeEstimate`, `getAssetsByOwner`, or `parseTransactions`.

Examples: - `heliusChain({ action: "getPriorityFeeEstimate", accountKeys: ["..."] })` - `heliusAsset({ action: "getAssetsByOwner", ownerAddress: "..." })` - `heliusTransaction({ action: "parseTransactions", transactions: ["..."] })` ## Prerequisites Before doing anything, verify these: ### 1.
