This one needs environment variables set before it will start: SOLANA_PRIVATE_KEY (base58 or JSON-array secret key of a DEDICATED Solana wallet holding USDC (pays per call). Configure this and/or EVM_PRIVATE_KEY; the x402 layer settles on whichever rail the 402 advertises. Paid tools return 402 without one; the free validate_mint tool still works.), EVM_PRIVATE_KEY (0x private key of a DEDICATED wallet holding USDC on Base (pays per call). Configure this and/or SOLANA_PRIVATE_KEY; the x402 layer settles on whichever rail the 402 advertises. Paid tools return 402 without one; the free validate_mint tool still works.), SOLANA_RPC_URL (Optional Solana RPC override used to build the payment (e.g. a Helius URL). Only read when SOLANA_PRIVATE_KEY is set.), SOLDEFI_BASE_URL (Base URL of a soldefi Worker. Defaults to the hosted production API (https://soldefi.thomenz.me).), X402_NETWORK (Set to 'base-sepolia' to pay on testnet, which switches BOTH rails (Solana devnet + Base Sepolia). Any other value, including unset, pays on mainnet.). The author declared them in the registry entry; get the values from the project itself.
