 The POA TokenBridge provides four operational modes:
 
-- [x] `Native-to-ERC20` **Coins** on a Home network can be converted to ERC20-compatible **tokens** on a Foreign network. Coins are locked on the Home side and the corresponding amount of ERC20 tokens are minted on the Foreign side. When the operation is reversed, tokens are burnt on the Foreign side and unlocked in the Home network. **More Information: [POA-to-POA20 Bridge](https://medium.com/poa-network/introducing-poa-bridge-and-poa20-55d8b78058ac)**
-- [x] `ERC20-to-ERC20` ERC20-compatible tokens on the Foreign network are locked and minted as ERC20-compatible tokens (ERC677 tokens) on the Home network. When transferred from Home to Foreign, they are burnt on the Home side and unlocked in the Foreign network. This can be considered a form of atomic swap when a user swaps the token "X" in network "A" to the token "Y" in network "B". **More Information: [ERC20-to-ERC20](https://medium.com/poa-network/introducing-the-erc20-to-erc20-tokenbridge-ce266cc1a2d0)**
 - [x] `ERC20-to-Native`: Pre-existing **tokens** in the Foreign network are locked and **coins** are minted in the `Home` network. In this mode, the Home network consensus engine invokes [Parity's Block Reward contract](https://wiki.parity.io/Block-Reward-Contract.html) to mint coins per the bridge contract request. **More Information: [xDai Chain](https://medium.com/poa-network/poa-network-partners-with-makerdao-on-xdai-chain-the-first-ever-usd-stable-blockchain-65a078c41e6a)**
 - [x] `Arbitrary-Message`: Transfer arbitrary data between two networks as so the data could be interpreted as an arbitrary contract method invocation.
