Build an unsigned native SOL transfer transaction using SystemProgram.transfer. Returns serialized base64 transaction for the agent to sign locally with sap_payments_finalize_transaction or sap_sign_transaction → sap_submit_signed_transaction. This is the hosted-safe equivalent of spl-token_transferSol (which is local-signer-only and cannot run on the hosted accountless server). Builder fee applies. SAP MCP execution guidance: Intent: hosted unsigned transaction builder. Pricing: paid builder; estimate first, then pay/build and finalize unsigned transactions locally when returned. Routing: paid hosted call; call sap_estimate_tool_cost first, then use sap_payments_call_paid_tool if the runtime cannot handle x402 natively. Signer boundary: hosted reads/builders never receive keypair bytes; value-moving results must be finalized locally when signing is required.
