Configuration

Variable	Required	Secret	Description
SOLANA_RPC_URL	—	—	Solana mainnet RPC endpoint. Defaults to https://api.mainnet-beta.solana.com — bring your own (Helius / Quicknode / Triton) for production traffic.
ETH_RPC_URL	—	—	Ethereum mainnet RPC for ENS resolution. Optional — falls back to ethers' default public providers.
HELIUS_API_KEY	—	yes	Optional Helius API key — enables exact supply + DAS data in pump_snapshot.
NVIDIA_API_KEY	—	yes	NVIDIA NIM key (nvapi-…) — leads the speak tool's TTS provider chain with the free Magpie TTS lane.
OPENAI_API_KEY	—	yes	OpenAI TTS — the speak tool's paid backstop when the free NVIDIA lane is unavailable.
REPLICATE_API_TOKEN	—	yes	Required for the generate_avatar tool (Replicate text/image-to-3D).
REPLICATE_TEXT_TO_AVATAR_MODEL	—	—	Replicate version hash pinned for text-to-3D — recommended: latest tencent/hunyuan-3d-3.1.
SOLANA_SECRET_KEY	—	yes	Optional default base58 Solana secret for wallet_send / pump_buy. Per-call secret args override this. Treat like cash.
THREE_MINT	—	—	Optional pump.fun mint address for $three so tools accept target="three" as shorthand.
MAX_SOL_PER_TX	—	—	Per-transaction spend cap in SOL for the execution tools (wallet_send, pump_buy, pump_launch, pump_collect_fees).
REQUIRE_CONFIRM	—	—	When on (default), execution tools refuse until re-issued with confirm:true. Set 0/false to disable the gate.
