-# Cosmos-SDK x/TokenFactory
+# Token Factory
+
+The `tokenfactory` module allows any account to create a new token with the name `factory/{creator address}/{subdenom}`. Because tokens are namespaced by creator address, this allows token minting to be permissionless, due to not needing to resolve name collisions. A single account can create multiple denoms, by providing a unique subdenom for each created denom. Once a denom is created, the original creator is given "admin" privileges over the asset. This allows them to:
+
+- Mint their denom to any account
+- Burn their denom from any account
+- Create a transfer of their denom between any two accounts
+- Change the admin. The `ChangeAdmin` functionality allows changing the master admin account, or even setting it to "", meaning no account has admin privileges of the asset.

+
+## Installation
+
+This repository provides the `tokend` application, a simple command-line application that demonstrates the functionality of the `tokenfactory` module. To build and install the `tokend` application, run:
+
+```bash
+make install
+```
+
+The application can be run with the following command:
+
+```bash
+tokend
+```
+
+## Test Node
+
+To run a test node with the `tokenfactory` module, run:
+
+```bash
+make install
+CHAIN_ID="local-1" HOME_DIR="~/.tokenfactory" TIMEOUT_COMMIT="500ms" CLEAN=true sh scripts/test_node.sh
+```
+
+## Usage
+
+The `tokend` application provides the following `tokenfactory` transactions:
+
+- `create-denom`: Create a new denom with the name `factory/{creator address}/{subdenom}`.
+- `mint`: Mint tokens to your address. You must be the admin of the denom to mint tokens.
+- `mint-to`: Mint tokens to another address. You must be the admin of the denom to mint tokens.
+- `burn`: Burn tokens from your address. You must be the admin of the denom to burn tokens.
+- `burn-from`: Burn tokens from another address. You must be the admin of the denom to burn tokens.
+- `force-transfer`: Transfer tokens between two addresses. You must be the admin of the denom to transfer tokens.
+- `change-admin`: Change the admin of the denom. You must be the admin of the denom to change the admin.
+- `modify-metadata`: Modify the metadata of the denom. You must be the admin of the denom to modify the metadata.
+
+and the following queries:
+
+- `params`: Get the tokenfactory module parameters.
+- `denom-authority-metadata`: Get the authority metadata of a denom.
+- `denoms-from-creator`: Returns a list of all denoms created by a given creator.
+
+## Testing
+
+To test the `tokenfactory` module, run:
+
+```bash
+make test
+```
+
+To run the `tokenfactory` module's end-to-end tests, run:
+```bash
+make local-image
+make ictest-tokenfactory
+```
+
+## Coverage
+
+To generate the coverage report of the `tokenfactory` module, run:
+
+```bash
+make local-image
+make coverage
+```
+
+## Simulation
+
+To run the `tokenfactory` module's full application simulation tests, run:
+
+```bash
+make sim-full-app
+```
+
+To run the `tokenfactory` simulation after state import test, run:
+
+```bash
+make sim-after-import
+```
+
+To run the `tokenfactory` application determinism simulation, run:
+
+```bash
+make sim-app-determinism
+```
+
+Append `-random` to the end of the commands above to run the simulation with a random seed, e.g., `make sim-full-app-random`.

+### Create Denom
+
+```bash
+# Usage:
+#   tokend tx tokenfactory create-denom [subdenom] [flags]
+tokend tx tokenfactory create-denom utest --from alice
+
+# Query the newly created token
+# cosmos1... is the creator address of the denom (alice) 
+tokend q tokenfactory denoms-from-creator cosmos1...
+denoms:
+- factory/cosmos1.../utest
+
+```
+
+### Modify Metadata
+
+```bash
+# Usage:

+
+# Modify the metadata of the utest denom
+# cosmos1... is the creator address of the denom (alice)
+# The ticker symbol is TST and the description is "My token description"
+# The denom exponent is 6
+tokend tx tokenfactory modify-metadata factory/cosmos1.../utest TST "My token description" 6 --from alice
+
+# Query the authority metadata of the factory/cosmos1.../utest denom
+tokend q tokenfactory denom-authority-metadata factory/cosmos1.../utest
