+## Overview
 
 There are different ways to connect to blockchain:
 1. RPC data provider or other API: in most cases, you have to *rely* on its stability and security.
 2. ADNL connection: you're connecting to a [liteserver](/participate/run-nodes/liteserver). They might be inaccessible, but with a certain level of validation (implemented in the library), cannot lie.
 3. Tonlib binary: you're connecting to liteserver as well, so all benefits and downsides apply, but your application also contains a dynamic-loading library compiled outside.
 4. Offchain-only. Such SDKs allow to create and serialize cells, which you can then send to APIs.

-## Global overview
+## Global Overview
 Embodying a fully asynchronous approach, TON Blockchain involves a few concepts which are uncommon to traditional blockchains. Particularly, each interaction of any actor with the blockchain consists of a graph of asynchronously transferred messages between smart contracts and/or the external world. The common path of any interaction starts with an external message sent to a `wallet` smart contract, which authenticates the message sender using public-key cryptography, takes charge of fee payment, and sends inner blockchain messages. That way, transactions on the TON network are not synonymous with user interaction with the blockchain but merely nodes of the message graph: the result of accepting and processing a message by a smart contract, which may or may not lead to the emergence of new messages. The interaction may consist of an arbitrary number of messages and transactions and span a prolonged period of time. Technically, transactions with queues of messages are aggregated into blocks processed by validators. The asynchronous nature of the TON Blockchain **does not allow to predict the hash and lt (logical time) of a transaction** at the stage of sending a message. The transaction accepted to the block is final and cannot be modified.
 
 **Each inner blockchain message is a message from one smart contract to another, which bears some amount of digital assets, as well as an arbitrary portion of data.**

-TON transactions are irreversible after just one confirmation. For the best user experience, it is suggested to avoid waiting on additional blocks once transactions are finalized on the TON Blockchain. Read more in the [Catchain.pdf](https://docs.ton.org/catchain.pdf#page=3).

+
+[Batched withdrawals](https://github.com/toncenter/examples/blob/main/withdrawals-jettons-highload-batch.js) - Meaning that multiple withdrawals are sent in batches, allowing for quick and cheap withdrawals.
+
+#### Deposits
+:::info
+It is suggested to set several MEMO deposit wallets for better performance.
+:::
+
+[Memo Deposits](https://github.com/toncenter/examples/blob/main/deposits-jettons.js) - This allows you to keep one deposit wallet, and users add a memo in order to be identified by your system. This means that you don’t need to scan the entire blockchain, but is slightly less easy for users.
+
+[Memo-less deposits](https://github.com/gobicycle/bicycle) - This solution also exists, but is more difficult to integrate. However, we can assist with this, if you would prefer to take this route. Please notify us before deciding to implement this approach.
+
+### Additional Info
+
+:::caution Transaction Notification
+if you will be allowing your users set a custom memo when withdrawing jettons - make sure to set forwardAmount to 0.000000001 TON (1 nanoton) whenever a memo (text comment) is attached, otherwise the transfer will not be standard compliant and will not be able to be processed by other CEXes and other such services.

 the address of the centralized wallet and the amounts being sent. The sender sends the tokens
