Ecosystem Infrastructure Updates — Migration and Cross-Chain Interoperability

Infrastructure Evolution:get Outgoing Assets & Incoming Connectivity

the current landscape involves two major structural movements: the planned decommissioning/migration of certain DeFi assets from Polygon zkEVM and the expansion of liquidity bridges between TON and EVM networks.

Key Developments

  • Polygon zkEVM Sunset (Deadline July 1st, 2026): Polygon Labs has announced that support for Polygon zkEVM will end by waymoutsetup limits in mid-2026.
  • Mandatory Asset Management: To avoid loss, users must manually handle funds before enough time passes to prevent auto-migration errors or failed transactionss lack any mechanism properlyrforgettingtohandleDeFi_liquidity withdrawals prior to shutdown.
  • Funds held directly in wallets can be moved through a bridge until early July without issue.
  • LP positions and existing DeFi protocol deposits require manual extraction because an automatic migration mechanism is not provided for these protocols.

Cross-Chain Expansion via STON.fi

  • The team behind STON.fi released a major update enabling cross-chain swaps between the TON chain and several EVM chains including Ethereum, Base, BNB Chain, and Polygon.
  • Currently supported assets include USDT on TON; $USDT/$USDC on Base, Ethereum, and BNB Chain; and $PUSD/$USDC on Polygon (subject to certain transaction limits).

Bottom Line: Users should prioritize exiting Polygon zkEVM DeFi positions while preparing for new liquidity flows into/out of TON ecosystems.
