Staking

claim​

- Claim FRA Token Rewards This function enables users to claim rewards earned from staking FRA tokens.

Parameters:​

• <WalletKeypar> - Wallet keypair

• <string> - the amout of rewards which users wants to claim

Results:​

• Promise<TransactionBuilder> - TransactionBuilder which should be used in Transaction.submitTransaction.

Example:​

const walletInfo = await Keypair.restoreFromPrivateKey(pkey, password);

// First, we create a transaction builder
const assetBuilder = await Asset.defineAsset(walletInfo, assetCode);

// Then, we submit a transaction
const handle = await Transaction.submitTransaction(assetBuilder);

delegate​

- Delegates FRA tokens This function allows users to delegate FRA tokens to a validator. This functionality is nearly identical to Transaction.sendToAddress except it adds one additional operation (i.e. add_operation_delegate) to the transaction builder.

Parameters:​

• <WalletKeypar> - Wallet keypair

• <string> - Target address for delegation

• <string> - delegation amout

• <string> - Asset Code

• <string> - Target validator Address

• <AssetBlindRules> - (optional) Confidential options for blind rule

Results:​

• Promise<TransactionBuilder> - TransactionBuilder which should be used in Transaction.submitTransaction.

Example:​

const ledger = await getLedger();

// This is the address funds are sent to.
// Actual `transfer to validator` process would be handled via added `add_operation_delegate` operation

const delegationTargetPublicKey = Ledger.get_delegation_target_address();
const delegationTargetAddress = await Keypair.getAddressByPublicKey(
  delegationTargetPublicKey
);

const walletInfo = await Keypair.restoreFromPrivateKey(pkey, password);

const assetCode = await Asset.getFraAssetCode();

const assetBlindRules: Asset.AssetBlindRules = {
  isTypeBlind: false,
  isAmountBlind: false,
};

const transactionBuilder = await StakingApi.delegate(
  walletInfo,
  delegationTargetAddress,
  amount,
  assetCode,
  validatorAddress,
  assetBlindRules
);

const resultHandle = await Transaction.submitTransaction(transactionBuilder);

getDelegateInfo​

- Get the delegation information This method is used to get the delegation information

Parameters:​

• <string> - wallet address

Results:​

• Promise<DelegateInfoResponse> - An instance of DelegateInfoDataResult containing the response and error..

Example:​

const address = "fra123sxde";

// Get the delegation information
const delegateInfo = await StakingApi.getDelegateInfo(address);

getValidatorList​

- Get validator list This method is used to get the list of validators.

Results:​

• Promise<validatorListResponse> - An instance of validatorListResponse containing the response and error..

Example:​

// Get validator list
const validatorList = await StakingApi.getValidatorList();

unStake​

- Unstake FRA tokens This function allows users to unstake (aka unbond) FRA tokens.

Parameters:​

• <WalletKeypar> - Wallet keypair

• <string> - the amount users wants to unstake

• <string> - validator's address

• <boolean> - fully unstake option. Default is false

Results:​

• Promise<TransactionBuilder> - TransactionBuilder which should be used in Transaction.submitTransaction.

Example:​

const walletInfo = await Keypair.restoreFromPrivateKey(pkey, password);

// Define whether or not user desires to unstake all the tokens, or only part of the staked amount
const isFullUnstake = false;

const transactionBuilder = await StakingApi.unStake(
  walletInfo,
  amount,
  validator,
  isFullUnstake
);

const resultHandle = await Transaction.submitTransaction(transactionBuilder);y
