Summary

  • TON rebrand to GRAM effective July 2 2026 coincides with Toncoin Token Bridge closure on September 1.
  • Cross-chain interoperability market growth from $492 million in 2023 to projected $2.56 billion by 2030 underscores demand for native solutions.
  • Security incidents such as the Kelp DAO exploit of a LayerZero bridge highlight persistent risks in blockchain bridges 2026.

TON projects and exchanges will run a coordinated update at 12:00 PM UTC on June 15 2026. They prepare for the GRAM rebrand. The Toncoin Token Bridge shuts down for good on September 1.

Users get fee waivers. They must meet the withdrawal deadline or lose access.

These moves arrive as the interoperability sector expands rapidly. They force renewed attention on TON bridges and the broader need for secure cross-chain interoperability beyond simple wrapped assets.

Context

The interoperability market grew from $492 million in 2023 to $619 million in 2024. Projections now place it at $2.56 billion by 2030. This expansion makes 2026 a key year for infrastructure upgrades.

TON bridges currently allow asset movement to other chains such as Ethereum. The upcoming GRAM rebrand and bridge shutdowns push the ecosystem to strengthen native interoperability.

Details

Nexo confirmed support for the GRAM rebrand. It noted that all ecosystem participants including exchanges must align on the June 15 update. The Toncoin Token Bridge closure requires users to withdraw assets before September 1 2026 or risk loss.

The largest DeFi hack of 2026 involved the Kelp DAO exploit that exposed a fatal flaw in a LayerZero bridge. This incident reinforces counterpoints about ongoing security risks even as market size increases.

"Bridge exploits like LayerZero highlight ongoing security risks despite market growth."

Projects listed on ton.app continue to offer bridge apps that connect TON to other blockchains. Yet the combination of the GRAM rebrand and bridge closure accelerates the shift toward solutions that move beyond wrapped tokens.

Outlook

Ecosystem participants should monitor security upgrades to TON bridges and prepare for further GRAM-related updates through the second half of 2026.
