v2026.2.3

Fixed

• Fixed USDT payment flow: the USDT balance check now correctly targets the wallet linked to the Fragment account (transaction["from"]), not the signing seed wallet. These are two distinct addresses — the seed wallet only signs the transaction and covers TON gas fees, while USDT is withdrawn from the Fragment-linked wallet.
• Fixed clean_decode() incorrectly treating binary TON cell payloads (e.g. jetton transfer messages with non-zero op codes) as text comments. Only cells with op code 0x00000000 are now decoded as snake-encoded UTF-8 strings; all other op codes return the raw Cell as-is.
• Restored and correctly wired USDT balance validation so WalletError is raised before broadcasting when the Fragment-linked wallet has insufficient USDT.

Note

• USDT (usdt_ton) payments require USDT to be held in the TON wallet that is linked to your Fragment account profile. The seed wallet configured in FragmentClient is only used to sign transactions and pay TON network fees.
