GetBlock x Tangem

As Tangem supports the widest possible range of blockchains, it’s crucial for them to be able to access all networks with a single RPC node provider.

With GetBlock, Tangem can retrieve and write blockchain data to all the blockchains it needs without having to run its own node infrastructure.
