Environment

Name	Required	Notes
SOLANA_RPC_URL	No	Solana mainnet RPC endpoint. Defaults to https://api.mainnet-beta.solana.com — bring your own (Helius / Quicknode / Triton) for production traffic.
ETH_RPC_URL	No	Ethereum mainnet RPC for ENS resolution. Optional — falls back to ethers' default public providers.
HELIUS_API_KEY	No	Optional Helius API key — enables exact supply + DAS data in pump_snapshot. Secret.
NVIDIA_API_KEY	No	NVIDIA NIM key (nvapi-…) — leads the speak tool's TTS provider chain with the free Magpie TTS lane. Secret.
OPENAI_API_KEY	No	OpenAI TTS — the speak tool's paid backstop when the free NVIDIA lane is unavailable. Secret.
REPLICATE_API_TOKEN	No	Required for the generate_avatar tool (Replicate text/image-to-3D). Secret.
REPLICATE_TEXT_TO_AVATAR_MODEL	No	Replicate version hash pinned for text-to-3D — recommended: latest tencent/hunyuan-3d-3.1.
SOLANA_SECRET_KEY	No	Optional default base58 Solana secret for wallet_send / pump_buy. Per-call secret args override this. Treat like cash. Secret.
THREE_MINT	No	Optional pump.fun mint address for $three so tools accept target="three" as shorthand.
MAX_SOL_PER_TX	No	Per-transaction spend cap in SOL for the execution tools (wallet_send, pump_buy, pump_launch, pump_collect_fees).
REQUIRE_CONFIRM	No	When on (default), execution tools refuse until re-issued with confirm:true. Set 0/false to disable the gate.
