 You can use the ['Token Bridge Dapp'](https://tokenbridge.rsk.co/) together with [Nifty Wallet](https://chrome.google.com/webstore/detail/nifty-wallet/jbdaocneiiinmjbjlgalhcelgbejmnid) or [Metamask with custom network](https://github.com/rsksmart/rskj/wiki/Configure-Metamask-to-connect-with-RSK) to move tokens between networks. This is the [Dapp guide](https://developers.rsk.co/tools/tokenbridge/dappguide/) if you don't know how to use it.
 Or you can use a wallet with the abi of the contracts. See the ['interaction guide using MyCrypto'](https://developers.rsk.co/tools/tokenbridge/usingmycrypto/) for more information on how to use the bridge.

 **OpenZeppelin Contracts is a library for secure smart contract development.** It provides implementations of standards like ERC20 and ERC721 which you can deploy as-is or extend to suit your needs, as well as Solidity components to build custom contracts and more complex decentralized systems.
 
-This fork of OpenZeppelin is set up as a **reusable Ethereum Package**. It is deployed to the kovan, rinkeby, and ropsten test networks, as well as to the main Ethereum network. You can reuse any of the pre-deployed on-chain contracts by simply linking to them using the [OpenZeppelin SDK](https://github.com/openzeppelin/openzeppelin-sdk), or reuse their Solidity source code as with the [vanilla version of OpenZeppelin Contracts](https://github.com/OpenZeppelin/openzeppelin-contracts).

-You can easily create upgradeable instances of any of the logic contracts listed above using the OpenZeppelin CLI. This will rely on the pre-deployed instances in mainnet, kovan, ropsten, or rinkeby, greatly reducing your gas deployment costs. To do this, just [create a new OpenZeppelin SDK project](https://docs.zeppelinos.org/docs/deploying.html) and [link to this package](https://docs.zeppelinos.org/docs/linking.html).

To avoid https://medium.com/nomic-labs-blog/malicious-backdoors-in-ethereum-proxies-62629adf3357[proxy selector clashing], which can potentially be used in an attack, this contract uses the https://blog.openzeppelin.com/the-transparent-proxy-pattern/[transparent proxy pattern]. This pattern implies two things that go hand in hand: 1. If any account other than the admin calls the proxy, the call will be forwarded to the implementation, even if that call matches one of the admin functions exposed by the proxy itself. 2. If the admin calls the proxy, it can access the admin functions, but its calls will never be forwarded to the implementation. If the admin tries to call a function on the implementation it will fail with an error that says \"admin cannot fallback to proxy target\". These properties mean that the admin account can only be used for admin actions like upgrading the proxy or changing the admin, so it's best if it's a dedicated account that is not used for anything else. This will avoid headaches due to sudden errors when trying to call a function from the proxy implementation. Our recommendation is for the dedicated account to be an instance of the {ProxyAdmin} contract. If set up this way, you should think of the `ProxyAdmin` instance as the real administrative interface of your proxy.",

To avoid https://medium.com/nomic-labs-blog/malicious-backdoors-in-ethereum-proxies-62629adf3357[proxy selector clashing], which can potentially be used in an attack, this contract uses the https://blog.openzeppelin.com/the-transparent-proxy-pattern/[transparent proxy pattern]. This pattern implies two things that go hand in hand: 1. If any account other than the admin calls the proxy, the call will be forwarded to the implementation, even if that call matches one of the admin functions exposed by the proxy itself. 2. If the admin calls the proxy, it can access the admin functions, but its calls will never be forwarded to the implementation. If the admin tries to call a function on the implementation it will fail with an error that says \"admin cannot fallback to proxy target\". These properties mean that the admin account can only be used for admin actions like upgrading the proxy or changing the admin, so it's best if it's a dedicated account that is not used for anything else. This will avoid headaches due to sudden errors when trying to call a function from the proxy implementation. Our recommendation is for the dedicated account to be an instance of the {ProxyAdmin} contract. If set up this way, you should think of the `ProxyAdmin` instance as the real administrative interface of your proxy.",

-Go to /federator/config copy `config.sample.js` file and rename it to `config.js` set mainchain and sidechain to point to the json files of the networks you are using, for example rsktestnet-kovan.json and kovan.json, `make sure to set the host parameter of those files`. Add a value to the key `FEDERATOR_KEY` in the .env file, and add the private key of the member of the Federation contract. The members of the federation are controled by the MultiSig contract, same that is owner of the Bridge and AllowedTokens contracts.
