Contributions welcome. Please check out the issues.

If you are adding a new coin type please try to follow the following rules:

use the existing ethereum.go and ethereum_test.go as templates
ensure you have 100% code coverage with your tests
try not to import large amounts of code; consider copying the relevant code rather than bringing in an entire project to use the address conversion functions
