Full-Service is pointed at a network at startup via its peer and ledger/tx-source configuration, so the same JSON-RPC surface runs against either TestNet or MainNet. TestNet uses valueless test MOB, letting integrators exercise account creation, address assignment, and the build/submit transaction flow without real funds. environments: - name: TestNet live: false funds: valueless test MOB configured_via: full-service --peer / --tx-source-url pointed at TestNet nodes - name: MainNet live: true funds: real MOB / eUSD configured_via: full-service --peer / --tx-source-url pointed at MainNet nodes notes: >- No hosted test cards or magic test tokens are published (MobileCoin is a self-custodial blockchain wallet, not a card acquirer); the sandbox is the TestNet ledger itself. Exact TestNet node URLs are published in the full-service repository configuration - not reproduced here to avoid drift.
