Stake

Creates a new stake account and returns a delegating transaction to sign.

Minimum stake amount is 1.1 SOL.

For devnet, use DaRwg7fkGs6Dnbh2cwPwmcsottXCuLBafCAJuQKySZq7 as the vote account.

Supports both standard recent blockhash nonces (default) and durable nonces (more information here):

For standard recent blockhash nonces, leave nonce_account and nonce_authority empty.
For durable nonces, define a nonce_account.
