-## Example environment variables for Soroban configuration
-## Safe for publishing: do NOT add real secrets here.
-
-# Choose which profile to use from `soroban.toml`. Set to one of the profile
-# names (e.g. `testnet`, `mainnet`, `sandbox`). If unset, the loader will
-# prefer a `testnet` profile in `soroban.toml` or fail if ambiguous.
 SOROBAN_NETWORK=testnet
-
-# Optional: Fully override the RPC URL. When set, this value takes precedence
-# over the `rpc_url` defined in the chosen profile inside `soroban.toml`.
-# SOROBAN_RPC_URL=https://soroban-testnet.stellar.org
-
-# Optional: Fully override the network passphrase. When set, this value takes
-# precedence over the `network_passphrase` defined in the chosen profile.
-# SOROBAN_NETWORK_PASSPHRASE=Test SDF Network ; September 2015
-
-# Admin key for contract deployment. Use 'soroban keys generate <name>' to create
-# a new key, then export it here. Required for contract initialization.
-# Example: SOROBAN_ADMIN_KEY=GDGQVOKHW4VEJRU2TETD6DBRKEO5ERCNF353LW5WBFW3JJWQ2BRQ6KDD
-
-# Behavior summary:
-# - If `SOROBAN_NETWORK` is set it selects a profile (or a well-known network
-#   name like `testnet`/`mainnet`/`sandbox`).
-# - `SOROBAN_RPC_URL` and `SOROBAN_NETWORK_PASSPHRASE` override the values from
-#   the selected profile when present.
-# - If neither environment variables nor an unambiguous profile exists, the
-#   loader fails with a clear message.
