Highlights

Until now, Tangany Custody Suite was mainly focused on write access to blockchains. That included the creation of new wallets and the execution of transactions and smart contract interactions. With the release of 1.5, we add the complementary read functionality to it.

The Read API allows all clients and partners to easily read the transaction and event history of wallets and smart contracts on Ethereum. With that, the solution supports all major types of interaction with blockchain using one unified API solution.

Please note, although demo account users can test-drive the Read endpoints without restrictions, due to its limited release status for productive workload paid-accounts are required to opt-in to this Beta feature by contacting the Tangany Support Team
