Fireblocks Kusama staking

This script allows to stake KSM via the Fireblocks system using the RAW signing API feature.

⚠️ Breaking Change in 2.0.0 ⚠️

Version 2.0.0 introduces a breaking change; as per this forum post on Polkadot - the controller is being deprecated.
As a result the following breaking changes were introduced:

• The function setController will no longer work and will results in an error
• The function bond no longer accepts 4 arguments, instead only 3 arguments - vaultAccountId: string, amount?: number, rewardDestination?: string (the controller argument was removed)

Prerequisites:

1. Run npm i from the project's directory to install all needed dependencies.

2. Create a vault account with KSM wallet which will act as a stash and controller account

3. Enable RAW signing feature by contacting Fireblocks's support team

4. Set transaction authorization policy rule that governs the RAW signing operation, the policy should include the following parameters:

   a. Initiator

   b. Designated Signer

   c. Asset - KSM

   d. Source (vault accounts) - Optional

   e. Authorizers - Optional

How to stake KSM

1. addProxy(<stake_account_vault_account_id>, <proxy_ksm_address>);

2. bond(<stash_account_vault_account_id>, <amount_to_stake>, optional - <reward_destination>);

reward_destination - Can be one of the following:

1. Stash (Default)

2. Staked - the rewards are sent back to the Stash and automatically bonded

How to stake extra KSM

1. bondExtra(<stash_account_vault_account_id>, <amount_to_bond>)

How to stop staking

1. chill(<stake_account_vault_account_id>);

2. unbond(<stake_account_vault_account_id>, <amount_to_unbond>);

3. 7 days after unbond() - withdrawUnbonded(<stake_account_vault_account_id>);

4. Optional - removeProxy(<stake_account_vault_account_id>, <proxy_ksm_address>);

How to change controller

1. setController(<stash_vault_account_id>, <controller_address>)
