According to a blog post Wednesday, the electrical Coin Company (ECC) has published an improved Android SDK and new iOS package to assist developers support shielded payments on mobile devices. The new software tools come alongside a light-weight server for backend processing of mobile shielded payments, meaning addresses, transaction amounts and memos within transactions are obfuscated.
While multiple zcash wallets exist already for laptop and desktop computers on the ZecWallet service, today's release may be a major step toward enabling shielded payments on mobile, the ECC said.
Due to the vast amount of knowledge needed to process shielded payments, facilitating them on mobile devices was technologically difficult. The ECC said it managed to trim data constraints down on mobile versions to implement its Sapling privacy tech.
“What previously required gigabytes of knowledge on a server is now accomplished with megabytes of knowledge and computation suitable for a phone,” the ECC said in an April 2019 blog concerning the Android lightclient release which predated today’s announcement.
