USD Coin jUSDC

jUSDC comes from the token bridge that the TON Foundation announced in a press release in April 2023. The bridge moves ERC-20 tokens from Ethereum into natively wrapped fungible tokens, jettons, on TON, and press coverage at the time described it as a two-way bridge. Justin Hyun, the foundation's Head of Incubation, called it the first unlimited bridge to go live on TON. According to press reports, the bridge's smart contracts were audited by three blockchain security firms: CertiK, Quantstamp and Hexens. The articles describe audits of the bridge and do not single out jUSDC.

A KuCoin news report says the TON team announced on May 23, 2026 that its Token Bridge (Bridge-v3) would shut down permanently on September 1, 2026. According to the same report, j-tokens such as jUSDT and jUSDC should be moved back to Ethereum before that date. Other reports name the affected jettons as jUSDT, jUSDC, jDAI and jWBTC. Bitget and Cryptopolitan report that the bridge oracles would withdraw their stake in June 2026 but keep processing transfers until the final date. Bitget adds that percentage-based transfer fees were waived for the remaining withdrawal period and that assets left in bridged form after September 1 would become inaccessible.

In April 2025, TON announced that from May 10, 2025 users could no longer bridge Gram, the native coin of the TON network, from TON to Ethereum or BNB Smart Chain. That step concerned the bridge for wrapped versions of the native coin, launched in 2021; transfers into TON and claims for past transfers stayed open. jUSDC belongs to Token Bridge v3, launched in April 2023 for j-tokens such as jUSDT, jUSDC, jDAI and jWBTC. The May 2025 reports describe only transfers of the native coin. The 2026 announcement closes the whole bridge on September 1, 2026, and jUSDC holders were told to bridge back to Ethereum before then.
