TON legacy bridge to close Sept. 1, 2026; withdraw assets

The TON Foundation confirmed its legacy Token Bridge at bridge-v3.ton.org will permanently close on Sept. 1, 2026. Users holding Wrapped Toncoin (TON) on Ethereum or BNB Chain must bridge those tokens back to the TON network, and holders of j-tokens-jUSDT, jUSDC, jDAI and jWBTC-stored in TON wallets must return them to Ethereum through the same bridge before that date. The foundation said percentage-based transfer fees will be waived for withdrawals during the remaining window.

The foundation confirmed all previously submitted transfers have been processed and that the protocol covered fees for unclaimed transfers. Bridge oracles will begin withdrawing their staked TON in June 2026 but will continue processing transfers until the shutdown. That timetable gives users roughly three months from the oracles’ exit in June to complete withdrawals before access is cut off. Any bridged assets left after Sept. 1 will not be accessible through the legacy bridge.

Users must use bridge-v3.ton.org to move assets back to the native TON network or to Ethereum, depending on the asset. Wrapped TON on Ethereum or BNB Chain needs to be bridged back to TON; j-tokens held in TON wallets must be returned to Ethereum via the same bridge. The fee waiver applies only to percentage-based transfer fees during the withdrawal period; users remain responsible for network gas and any chain-specific fees.

The foundation advised account holders to check wallets now and start transfers well before the deadline to allow for transaction confirmations, potential network congestion and wallet-specific delays. It recommended confirming that transfers appear as completed on both source and destination chains and verifying the correct bridge URL to reduce phishing risk.

The bridge retirement follows governance and infrastructure changes within the TON ecosystem, including increased on-chain activity and DeFi usage after Telegram’s involvement and a recent protocol upgrade tied to Telegram’s leadership. The foundation described the shutdown as part of a transition away from the older bridge architecture toward newer cross-chain solutions and native DeFi infrastructure on TON.

Operators and integrators that use the legacy bridge for liquidity routing or custodial flows are expected to migrate to updated tooling before the September deadline. Affected users and service providers should monitor official TON channels for any further technical notices or schedule updates.
