The TON Foundation has set September 1 as the date when its legacy bridge will be permanently decommissioned, creating a clear deadline for users who still hold assets tied to that route. The affected service is bridge-v3.ton.org, according to TON materials.

The notice applies to users holding Wrapped TON as an ERC-20 token on Ethereum or BNB Chain, as well as holders of j-tokens on TON such as jUSDT. Those users need to bridge assets back to their native form before the shutdown, or they may lose practical access through the legacy path.

Which assets are affected

The retirement covers wrapped and bridged assets that still rely on TON’s older bridge infrastructure. In practical terms, that includes Wrapped TON circulating on Ethereum or BNB Chain and certain TON-based j-tokens created through the same legacy setup.

The distinction matters because wrapped assets are representations rather than the native asset itself. Their usability depends on the supporting bridge remaining available to handle the conversion back to the original form. Once that infrastructure is retired, the normal route for unwinding those positions disappears.

A planned transition, not a security incident

TON has described the move as a planned infrastructure transition rather than a hack or emergency event. That framing is important because bridge shutdowns can easily be misunderstood, especially in a market where bridge failures have often been associated with exploits or frozen funds.

Even so, a scheduled decommissioning still carries operational risk for users who miss the announcement or misunderstand whether their holdings are included. The immediate concern is not a reported technical failure but the need for holders to act before the old system goes offline.

Why the deadline matters

Bridges are among the more sensitive parts of crypto infrastructure because they sit between networks and maintain the accounting that supports wrapped assets. When a bridge is deprecated, the main risk can shift from technology to coordination: users must know what is changing, determine whether they are affected, and complete the required steps in time.

For TON users, the September 1 cutoff is the key milestone. The Foundation’s warning is that access through the legacy route may become limited or impossible after that date, which means delaying the conversion could leave affected holders without an easy way to return those assets to native form.

Next confirmed step for holders

The only confirmed next step in the transition is the September 1 shutdown of bridge-v3.ton.org. Until then, users holding Wrapped TON on Ethereum or BNB Chain, or j-tokens on TON such as jUSDT, need to verify whether their assets depend on the legacy bridge and, if so, bridge them back before the cutoff.

TON materials also indicate that users should rely on official instructions and the correct interface during the migration window. Transition periods around bridges can create confusion, and after the deadline the legacy option is expected to be retired permanently.
