The usage of the staked_conn interface is similar to the RPC interface, primarily providing the sendTransaction method, which directly connects to our validator node.

When calling the sendTransaction method of staked_conn, please note the following:

• A maximum of 5 calls per second is allowed.
• You need to transfer an amount greater than or equal to 0.001 SOL to any of the following accounts:
