Polkadot Asset Hub Deposits: Match the Receiving Network

For a DOT exchange deposit, match the wallet’s actual sending chain with the network in the recipient’s current instructions. Do not infer acceptance from a familiar Polkadot address, an old Relay Chain guide or the fact that the platform lists DOT for trading. If the receiving side requires Polkadot Asset Hub, the transfer must follow its supported Asset Hub workflow.

Treat the migration as history, not a new claim request

The current Polkadot migration guide records the Polkadot Asset Hub migration as completed on November 4, 2025. It describes the movement of balances and functions without requiring ordinary users to send their funds to a new claimant. Do not confuse this completed network change with a stranger’s demand for a fresh migration deposit.

The Asset Hub overview explains its expanded role beyond asset issuance. That helps explain why older screenshots can point to a chain that is no longer the right place for your everyday DOT operation. It does not remove the need to read the receiving platform’s deposit page at the time of transfer.

A service can use “Polkadot” as a short interface label while its detailed instruction names Asset Hub. Another screen may expose several network choices. Before relying on either, establish what the label means in that product. A matching logo and currency ticker are useful for navigation, but they do not answer the network acceptance question.

Address compatibility is not a deposit agreement

The Polkadot accounts documentation describes multiple address representations and the move toward a unified format. It also notes that some exchange interfaces may still require legacy formats during their transition. That is a reason to use the recipient’s supported format, not a reason to identify the transfer network from the first character alone.

Do not paste an address into an online converter merely to make a rejected withdrawal form accept it. First determine whether the rejection concerns formatting, the selected network or the underlying account. Reformatting an account identifier does not instruct a service to monitor a different chain. If the form and deposit instructions disagree, ask the sending or receiving service to resolve that mismatch.

Use an exchange’s own policy as evidence for that exchange

For example, Bitfinex’s DOT support page states that it supports Asset Hub deposits after the migration and treats Relay Chain deposits as incorrect deposits subject to its recovery process. This is a concrete policy for that platform. It is not a promise that another exchange has the same detection, recovery availability or terms.

Historical announcements also need their dates read carefully. Binance’s Asset Hub integration announcement is dated July 11, 2024. Finding it does not establish that deposits are open for your account today. A later migration announcement and a live maintenance state answer different questions from an older integration notice.

In a fictional example, Nina has a saved screenshot from a previous deposit and a current receiving page with different network wording. The current instruction deserves a fresh check rather than being overruled by the screenshot. She should ask which sending option matches the present deposit, keeping the old record only as evidence of what she did earlier.

Check the proposed payment before signing

1. Open the receiving service’s current DOT deposit page and record its network, address and restrictions.
2. Locate the wallet balance on the actual chain, rather than relying only on an aggregated DOT total.
3. Confirm that the intended transfer uses the receiving service’s supported network and account format.
4. Review the destination, asset and amount in the signing flow; distinguish a transfer from a conversion or other action.
5. If a cross-chain step is required, verify that step separately and establish the final received balance before the exchange deposit.
6. Keep the submitted transaction identifier and verify its result on the corresponding chain.

A small trial is meaningful only after support and any deposit minimum are understood. It cannot turn an unsupported chain into a supported one. Do not send repeated tests while the first outcome remains unexplained. If a service’s wording is ambiguous, the useful answer is a specific chain and supported flow, not another assurance that “DOT is listed.”

Inspect the chain that actually received the transfer

Use the Subscan guide for the mechanics of finding extrinsics, events and account activity. Search in the right chain context and inspect the intended asset movement. A missing result in a Relay Chain view is not evidence that an Asset Hub transfer vanished, and the reverse inference is equally unreliable.

The Polkadot transaction reference explains extrinsics as the network’s transaction mechanism. Keep the actual call and its result with your payment record. For a cross-chain workflow, do not replace the destination evidence with a screenshot showing only that the initial instruction was submitted.

In Nina’s case, the investigation should produce one of several explicit findings: the payment never reached the intended chain, it reached the wrong account, it reached the correct account on an unsupported network, or it reached the supported destination and still needs service-side reconciliation. Those findings require different assistance. Label an unknown result as unknown instead of guessing which case applies.

An incorrect-chain deposit needs an assessment, not another deposit

Give the receiving service the chain, transaction identifier, destination, amount, time and the instruction you followed. Ask whether it controls that account on the actual chain and whether it can assess credit or recovery. If it describes a recovery process, request its conditions for your specific transaction. Do not infer a guaranteed result from the presence of a recovery link.

If the funds are still in a wallet you control, investigate the supported route using your authorized wallet and the destination requirements. If they are already under a service’s control, your original sending key does not authorize that service’s return. A public explorer can clarify where the funds are; it cannot grant control of an exchange account.

The DOT asset page provides coin context. Before starting a simple swap, inspect the live order’s network rather than carrying over a label from another platform. This article does not independently establish KOT.CASH’s present DOT routing. The practical rule is to preserve the complete combination: asset, actual chain, supported recipient and verified result.
