# Transfer `TransferTaker` implementation of taker provides an ability to take available asset from pool *after* giving asset on another chains though. The give operation is performed via `TransferGiver` contract, that emits `TransferGive` event that is verified by the taker. > `TransferTaker` keep record of already `taken` operation so double-takes are not possible. The records are per take asset `receiver` (i.e. taker's `caller`) and `nonce`. > > Managing `nonce`s is `receiver`'s responsibility and should be done with *caution*. Sending asset via *two or more* `give` (or `giveHold`) functions with *the same* `takeChain`, `takeReceiver` and `takeNonce` params will result in only *one* take possible (since subsequent ones will be blocked after the record of a first one). ### Relief Giver There is another variant of `TransferGiver`: `TransferReliefGiver`. It works similarly to the original one, except it's aware of its `IExtraRelief`-capable tuner (such as `ElasticTuner`). After providing asset to pool, the giver collects *possible* surplus assets for the rebalance-beneficial action and sends them back to the caller. --- # Agent Instructions: Querying This Documentation If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.
