Wrap FIO Tokens

This action wraps FIO Tokens to another chain.

Currently, only Ethereum chain is supported (chain_code: ETH). When FIO Tokens are wrapped, they are first sent to an escrow contract on the FIO Chain. Next, a set of oracles run by FIO Block Producers detect the wrapped tokens and mint the equivalent amount of WFIO to the supplied Ethereum public_address.

See Wrapped FIO Token Guide for more information.
