+
+Test utility for [TestStableToken](https://github.com/logos-messaging/logos-messaging-rlnv2-contract/blob/main/test/TestStableToken.sol) used in the Logos Messaging RLN v2 contract tests.
+
+Given the token contract address and an Ethereum JSON-RPC endpoint, it allows minting and transferring TestStableToken tokens.
+Given the contract address, it can also query allowances.
+
+Details about the use of TestStableToken can be found in the [TST README](https://github.com/logos-messaging/logos-messaging-rlnv2-contract/blob/main/test/README.md)
+
+## Configuration
+
+Set the following environment variables (or use a `.env` file):
+
+- `TOKEN_CONTRACT_ADDRESS`: The token contract proxy address
+- `RLN_CONTRACT_ADDRESS`: The RLN contract proxy address
+- `RLN_RELAY_ETH_CLIENT_ADDRESS`: The Ethereum JSON-RPC endpoint
+- `ETH_FROM`: The default user account address
+- `PRIVATE_KEY`: Private key for write operations (transfer, mint)
+
+## Usage
+
+The `interactions.py` script provides a CLI interface for all token operations.
+
+### Read-Only Commands (no PRIVATE_KEY required)
+
+Get total supply:
+```bash
+python3 tools/token_management/interactions.py total-supply
+```
+
+Get max supply:
+```bash
+python3 tools/token_management/interactions.py max-supply
+```
+
+Get contract owner:
+```bash
+python3 tools/token_management/interactions.py owner
+```
+
+Get implementation address:
+```bash
+python3 tools/token_management/interactions.py implementation
+```
+
+Get balance (defaults to USER_ACCOUNT_ADDRESS from env):
+```bash
+python3 tools/token_management/interactions.py balance
+python3 tools/token_management/interactions.py balance 0xYourAddress
+```
+
+Get allowance (defaults to USER_ACCOUNT_ADDRESS and RLN_CONTRACT_PROXY_ADDRESS):
+```bash
+python3 tools/token_management/interactions.py allowance
+python3 tools/token_management/interactions.py allowance 0xOwner 0xSpender
+```
+
+Check if address is a minter (defaults to USER_ACCOUNT_ADDRESS):
+```bash
+python3 tools/token_management/interactions.py is-minter
+python3 tools/token_management/interactions.py is-minter 0xAddress
+```
+
+### Write Commands (PRIVATE_KEY required)
+
+All write commands accept an optional `--private-key` flag to specify a custom private key. If not provided, the `PRIVATE_KEY` environment variable will be used.
+
+Transfer tokens:
+```bash
+python3 tools/token_management/interactions.py transfer 0xRecipient 100.5
+python3 tools/token_management/interactions.py transfer 0xRecipient 100.5 --private-key 0xYourPrivateKey
+```
+
+Mint tokens:
+```bash
+python3 tools/token_management/interactions.py mint 0xRecipient 1000
+python3 tools/token_management/interactions.py mint 0xRecipient 1000 --private-key 0xYourPrivateKey
+```
+
+Approve spender to use tokens:
+```bash
+python3 tools/token_management/interactions.py approve 0xSpender 500
+python3 tools/token_management/interactions.py approve 0xSpender 500 --private-key 0xYourPrivateKey
+```
+
+### Help
+
+View all available commands:
+```bash
+python3 tools/token_management/interactions.py --help
+```
