Telegram CEO Pavel Durov announced Monday that The Open Network's native cryptocurrency will be renamed from Toncoin to Gram, reviving the original name proposed in the project's first white paper as part of his ongoing "Make TON Great Again" initiative.

"Gram was the original name of TON's currency in the first white paper," Durov wrote in a Telegram post. "We're returning to our roots and starting a new chapter."

The transition is expected to take approximately three weeks. TON will remain the name of the blockchain, while Gram becomes the name of the native currency.

The rebrand is the fourth of seven planned steps in Durov's MTONGA campaign, though the remaining three steps have not yet been publicly disclosed.

Durov first outlined the transition in April when he celebrated a network upgrade that made TON ten times faster and introduced sub-second transaction settling. The other two previously revealed steps included reducing transaction fees by roughly sixfold and announcing plans for Telegram to replace the TON Foundation as the ecosystem's primary steward and largest validator.

The Gram rebranding restores the name originally envisioned by Telegram's blockchain project, which referred to TON as an acronym for Telegram Open Network and its native Gram cryptocurrency.

Telegram launched the original TON project in 2018 but abandoned it in 2020 following a legal battle with the U.S. Securities and Exchange Commission, which forced the company to halt sales of its Gram tokens on the grounds that the offering violated securities laws.

Independent developers later revived the project under the name The Open Network. The blockchain has since become deeply integrated with Telegram's ecosystem of applications, primarily focused on payments and digital asset trading.

Following the announcement, TON surged more than 15% as market participants responded positively to the rebrand and the broader MTONGA roadmap. The token's rally reflects growing confidence in Telegram's renewed commitment to the network's long-term development.
