Each weekday leading up to devcon2, Nexus will highlight a dapp, library, or package (something with a dappfile) as a promotion of our toolchain and as case studies for other developers. Yesterday's Post.
The Ether token wrapper wraps "native" Ether into an ERC20-compliant address. Using .send or .call to transfer Ether both have their own unintuitive edge cases and is a common cause of vulnerabilities.

An example app using the ETH token wrapper is https://mkr.market, which will get its own dapp-a-day later.
Between this package and ds-actor, most of the gotchas related to native direct calls are now non-issues.
We are almost ready to start looking at interesting dapps. There are a just a few more building blocks to cover. Stay tuned!
