• BLOCKRUN_WALLET_KEY secret — Optional: EVM private key (0x-prefixed hex) for USDC payments on Base; also the Polymarket signer. If not set, a wallet is auto-generated.
• SOLANA_WALLET_KEY secret — Optional: Solana private key (bs58) for USDC payments on Solana. Setting it selects the Solana chain. If not set, a wallet is auto-generated.
• BLOCKRUN_API_KEY secret — Optional: BlockRun account API key; bills your prepaid balance instead of a wallet (no per-call network fee). Takes priority over a wallet when set.
