I recently found out about Insight API, https://github.com/bitpay/insight-api
Maybe someone could help/try this out to make work with peercoin?
It would make Trezor support a step closer. https://blog.trezor.io/multi-currency-support-bitcoin-dash-and-zcash-in-trezor-wallet-7377d812112a
it looks like this https://insight.bitpay.com/
from trezor blog:
TREZOR Wallet utilizes Insight/Bitcore in order to grab information about cryptocurrency/blockchain. A functioning Insight is therefore the main requirement for integration of any coin into TREZOR Wallet.
(Bitcore has already been ported to ppc by hrobeers.)
