Configuration

Variable	Required	Secret	Description
SOLANA_PRIVATE_KEY	—	yes	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	—	yes	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.
