103tools discovered
Showing 25 of 103 from the live probe.
Create Basic Transaction
Returns a serialized basic transaction.
Create Basic Transaction With Data
Returns a serialized basic transaction with an arbitrary data field.
Create Deactivate Validator Transaction
Returns a serialized `deactivate_validator` transaction. You need to provide the address of a basic account (the sender wallet) to pay the transaction fee.
Create Delete Validator Transaction
Returns a serialized `delete_validator` transaction. The transaction fee will be paid from the validator deposit that is being returned. Note in order for this transaction to be accepted fee + value should be equal to the validator deposit, which is not a fixed value: Failed delete validator transactions can diminish the validator deposit
Create New Htlc Transaction
Returns a serialized transaction creating a new HTLC contract.
Create New Staker Transaction
Returns a serialized `new_staker` transaction. You need to provide the address of a basic account (the sender wallet) to pay the transaction fee.
Create New Validator Transaction
Returns a serialized `new_validator` transaction. You need to provide the address of a basic account (the sender wallet) to pay the transaction fee and the validator deposit. Since JSON doesn't have a primitive for Option (it just has the null primitive), we can't have a double Option. So we use the following work-around for the signal data: \"\" = Set the signal data field to None. \"0x29a4b...\" = Set the signal data field to Some(0x29a4b...).
Create New Vesting Transaction
Returns a serialized transaction creating a new vesting contract.
Create Reactivate Validator Transaction
Returns a serialized `reactivate_validator` transaction. You need to provide the address of a basic account (the sender wallet) to pay the transaction fee.
Create Redeem Early Htlc Transaction
Returns a serialized transaction redeeming a HTLC contract using the `EarlyResolve` method.
Create Redeem Regular Htlc Transaction
Returns a serialized transaction redeeming a HTLC contract using the `RegularTransfer` method.
Create Redeem Timeout Htlc Transaction
Returns a serialized transaction redeeming a HTLC contract using the `TimeoutResolve` method.
Create Redeem Vesting Transaction
Returns a serialized transaction redeeming a vesting contract.
Create Remove Stake Transaction
Returns a serialized `remove_stake` transaction. The transaction fee will be paid from the funds being removed.
Create Retire Stake Transaction
Returns a serialized `retire_stake` transaction. You can pay the transaction fee from a basic account (by providing the sender wallet) or from the staker account's balance (by not providing a sender wallet).
Create Retire Validator Transaction
Returns a serialized `retire_validator` transaction. You need to provide the address of a basic account (the sender wallet) to pay the transaction fee.
Create Set Active Stake Transaction
Returns a serialized `set_active_stake` transaction. You can pay the transaction fee from a basic account (by providing the sender wallet) or from the staker account's balance (by not providing a sender wallet).
Create Stake Transaction
Returns a serialized `stake` transaction. The funds to be staked and the transaction fee will be paid from the `sender_wallet`.
Create Update Staker Transaction
Returns a serialized `update_staker` transaction. You can pay the transaction fee from a basic account (by providing the sender wallet) or from the staker account's balance (by not providing a sender wallet).
Create Update Validator Transaction
Returns a serialized `update_validator` transaction. You need to provide the address of a basic account (the sender wallet) to pay the transaction fee. Since JSON doesn't have a primitive for Option (it just has the null primitive), we can't have a double Option. So we use the following work-around for the signal data: null = No change in the signal data field. \"\" = Change the signal data field to None. \"0x29a4b...\" = Change the signal data field to Some(0x29a4b...).
Get Account By Address
Tries to fetch the account at the given address.
Get Accounts
Fetches all accounts in the accounts tree. IMPORTANT: This operation iterates over all accounts in the accounts tree and thus is extremely computationally expensive.
Get Active Validators
Returns a collection of the currently active validator's addresses and balances.
Get Address Book
Returns the address book
Get Batch At
Returns the batch number at a given `block_number` (height).
