Lido events

Rebase

Methods

getLastRebaseEvent

Output Parameters:

• Type: RebaseEvent

getFirstRebaseEvent

Input Parameters:

• props: { days, fromBlockNumber }
  • days (Type: number): The number of days ago from which to start searching for the first rebase event.
  • fromBlockNumber (Type: number | undefined): Block number from which to start the search.

Output Parameters:

• Type: RebaseEvent

getRebaseEvents

Input Parameters:

Warning: specifying timestamp/seconds/days will result in binary search for fitting block number which will negatively affect rpc request count and execution time

Sub types:

• blockType object that contains one of possible fields:

  • block block number(Type: BigInt) or Block Tag(excluding pending)
  • timestamp timestamp in seconds(type:BigInt) since epoch time

• backType object that contains one of possible fields:

  • seconds (Type: BigInt): seconds back
  • days (Type: BigInt): days back
  • blocks (Type: BigInt): block back

Props:

• to (Type: blockType optional) defaults to {block:"latests"} upper bound for events parsing

• maxCount (Type: number optional) maximum count of events to return, if omitted will return all events in range

• stepBlock: (Type: number optional) defaults to 50000, maximum block range per 1 request

• from (Type: blockType) lower bound for events parsing or

• back (Type: backType) alternative way to define lower bound relative to to

Output Parameters:

• Type: Array of RebaseEvent objects

getLastRebaseEvents

Input Parameters:

• props: { count, stepBlock? }
  • count (Type: number): how many last rebase events to return
  • stepBlock: (Type: number optional) defaults to 50000, maximum block range per 1 request

Output Parameters:

• Type: Array of RebaseEvent objects

Examples

import { LidoSDK } from '@lidofinance/lido-ethereum-sdk';

const lidoSDK = new LidoSDK({
  rpcUrls: ['https://rpc-url'],
  chainId: 5,
});

const lastRebaseEvent = await lidoSDK.events.stethEvents.getLastRebaseEvent();
const firstRebaseEvent = await lidoSDK.events.stethEvents.getFirstRebaseEvent({
  days: 3,
});
const lastRebaseEventsByCount =
  await lidoSDK.events.stethEvents.getLastRebaseEvents({ count: 7 });
const lastRebaseEventsByDays =
  await lidoSDK.events.stethEvents.getRebaseEventsByDays({ days: 7 });

console.log(lastRebaseEvent, 'last rebase event');
console.log(firstRebaseEvent, 'first rebase event');
console.log(lastRebaseEventsByCount, 'last rebase events by count');
console.log(lastRebaseEventsByDays, 'last rebase events by days');
