IdleBatchedMint

The IdleBatchedMint contract allows to queue multiple deposits of underlying tokens and send them to its IdleToken contract to mint Idle tokens in batches, allowing multiple users to avoid paying high gas fees for the final mintIdleToken transaction.

Example:

  • User A calls IdleBatchedMint.deposit(uint256 amount)
  • User B calls IdleBatchedMint.deposit(uint256 amount)
  • User C calls IdleBatchedMint.deposit(uint256 amount)
  • Any user can call IdleBatchedMint.executeBatch(bool _skipRebalance)

After the last step, the IdleBatchedMint contract is the owner of the Idle tokens, but at any point in time, users A, B, and C can call IdleBatchedMint.withdraw(uint256 batchId) to withdraw their own Idle tokens.
