You cannot transfer tokens from an arbitrary account. Imagine I have a contract that can transfer tokens from your balance. That does not sound secure, right?

The approach you want to implement is the following: when account a.testnet calls a contract, it attaches some tokens with the call (create a transaction with non-zero deposit in FunctionCall action), and then, inside the contract, create a Transfer to the account b.testnet.

In AssemblyScript, you can use ContractPromiseBatch.create('b.testnet').transfer(context.attachedDeposit) to issue the transfer.

In Rust, Promise::new("b.testnet".to_string()).transfer(near_sdk::env::attached_deposit())
