First, identify which type of product you are using.
A single branded application may provide access to both an exchange account and a Web3 wallet. The former is typically managed by a platform’s account system, while the control and recovery mechanisms for the latter depend on the specific wallet implementation. Similar user interfaces do not imply identical asset custody, responsible parties, or recovery paths. Before taking any action, verify the product name, account type, and terms of service; do not make assumptions simply because balances appear within the same mobile application.
Control depends on the specific implementation
Wallets may utilize mnemonic phrases (seed phrases), private keys, smart accounts, or other recovery arrangements; you should verify based on the method you originally used to set up your wallet. A login password for an exchange is not equivalent to a blockchain private key, and a wallet address is not the same as a platform account ID. Customer support cannot guarantee the recovery of all wallets, nor should one assume that all products labeled "Web3" employ the same custody model; always refer to the official documentation provided by the specific product.
Transfers involve different types of evidence
When withdrawing funds from an exchange to a wallet, you should verify the status of the withdrawal request on the platform, the transaction on the blockchain, and the asset balance displayed in your wallet. Internal transfers may not generate the same type of on-chain proof. Keep records of the network, address, amount, transaction fees, and transaction identifiers (TXIDs), and distinguish between the platform having processed the transaction and the wallet having received the funds. Issues such as using the wrong network, omitting a required memo, or service suspensions cannot be resolved simply by switching between different user interfaces.
Fees originate from different sources
Exchange trading fees, platform withdrawal fees, on-chain gas fees for wallets, and charges from third-party applications are distinct costs. Seeing a token balance in a wallet does not guarantee that you have sufficient native assets to cover network (gas) fees; conversely, holding an asset in a platform account does not necessarily mean it is directly available for use in a wallet. If you encounter an "insufficient gas" error, do not purchase so-called "activation packages" from strangers—always check the specific rules for the network in question.
Use the designated channels for recovery and support.
Account recovery for exchanges should follow verified official procedures, while wallet recovery is handled according to the specific type of wallet. Be highly cautious of anyone claiming to be customer support who asks for your seed phrase or private key, or instructs you to import your wallet into one they provide. While identity verification may be part of the account recovery process on a platform, it should not be mistaken as a means to reverse on-chain transactions or reconstruct lost, independent private keys.
Compile a table defining the scope of each product.
Document the product name, contracting entity, control mechanism, required recovery materials, fee structure, support channels, and regional eligibility. Note that interface labels may change following software updates; always refer back to the terms and conditions rather than relying solely on screenshots. This document does not confirm that any specific product is available in all regions, nor does it constitute an endorsement by the platform. Both on-chain operations and custodial accounts carry their own inherent technical and service-related risks.
