Hello, in the ongoing crypto winter ethereum & co. programming series I put together some more gems. The new abigen gem lets you generate ready-to-use (blockchain) contract services / function calls for ethereum & co. via application binary inferfaces (abis). Bonus: Via the new natspec gem you can even “auto-include” nat(ural) spec(ification) comments / documentation in the generated ruby code. See the pre-packaged auto-generated ruby classes in the ethlite-contracts gem, for some first real-world samples.
