To get help about a specific command use tl-deploy COMMAND --help.

Deploy a Currency Network

A currency network contract handles all trustlines with the same denomination. It allows for transfers between the users of this network.

You can deploy a currency network with the name Testcoin and symbol TST by using the command

tl-deploy currencynetwork Testcoin TST

To find out more about the possible options, use

tl-deploy currencynetwork --help

The mandatory arguments are the NAME and the SYMBOL of the network. All other parameters are optional as they have either default values or are not needed in some cases.

Deploy an upgradeable currency network

Upgradeable currency networks are handled via a beacon, an implementation, and one or multiple proxies. The implementation contract contains the logic of the currency network code and is referred to by the beacon. The proxies refer to the beacon to find which implementation logic to use. This allows to update the implementation used by multiple proxies at the same with a single transaction to update the implementation referred to by the beacon.

Only the owner of the beacon / proxies are able to change the referred implementation / beacon. Make sure the owner key is safely stored and replicated, losing it will prevent upgrading currency networks in the future. Be aware that the owner of a proxy will not be able to interact with the logic of the implementation (here the currency network).

1. The first step is to deploy the desired implementation for example a currency network:

tl-deploy currencynetwork Implementation IMPL

You need to write down the address of the deployed implementation to use it when you deploy the beacon. It does not matter which argument you used for the name, symbol, decimals, etc of the contract, as its storage will not be used.

2. The second step is to deploy a beacon that points to the implementation.

tl-deploy beacon --implementation <implementation_address> --owner <owner_address> --gas-price <gas_price>

Similarly, you should write down the address of the deployed beacon.

3. The last step is to deploy one (or as many as you want) proxy.

tl-deploy currency-network-proxy --beacon <beacon_address> --owner <owner_address> --gas-price <gas_price> NAME SYMBOL

This will give you the address with which your users should interract as a currency network. The values for the name, symbol, fee-rates, and other are the ones that will be taken into account.

Deploy an Exchange

An exchange allows users of different currency networks to exchange 1. trustlines currencies, 2. trustlines currency for ERC 20 tokens and 3. trustlines currency for wrapped Ether. This exchange is an extension to the 0x protocol, adding support for Trustlines currencies.

You can deploy an exchange with

tl-deploy exchange

To get further information, use

tl-deploy exchange --help

The address of this exchange can be used as input for the --exchange-contract option when creating a currency network.

Deploy Identity Contracts

We use identity proxy contracts to enable the use of meta-transactions. Through that, new users can directly interact with the deployed currency network contracts without the need of coins to pay for transaction fees. Therefore two contracts need to be deployed.

1. Implementation of the identity contract
2. Identity proxy factory contract

Identity Implementation

This contract is the implementation of an identity contract. We need to deploy it to set the implementation of deployed identity proxies.

Run

tl-deploy identity-implementation

To get further information, run

tl-deploy identity-implementation --help

Proxy Factory

The proxy factory contract is used to create identity proxies, where the implementation need to be set.

Run

tl-deploy identity-proxy-factory

Same as above you can get further information on the usage by running

tl-deploy identity-proxy-factory --help
