The problem DefiChain Transaction Bundler solves

DefiChain Transaction Bundler reduces the number of separate JSON RPC requests that need to be sent (especially useful if using remote nodes like Infura), while also providing the guarantee that all values returned are from the same block (like an atomic read) and returning the block number the values are from (giving them important context so that results from old blocks can be ignored if they're from an out-of-date node).
