Former US president Donald Trump along with his sons and entrepreneurs late Monday launched a cryptocurrency platform but provided few details.

Little was revealed about the Trump family crypto project during a two-hour online presentation other than an offer to let people buy digital "tokens" giving them a vote in platform decisions.

The event went ahead as planned despite an apparent assassination attempt against Trump on Sunday at his golf club in West Palm Beach, Florida.

World Liberty Financial intends to offer services based on so-called decentralized finance, a mechanism that eliminates the need for an intermediary such as a bank to carry out transactions with a third party, the politics-laced discussion indicated.

Decentralized finance, or DeFi, is based on so-called blockchain technology, which keeps a theoretically open but tamper-proof record of transactions.

World Liberty Financial will enable users to lend or borrow cryptocurrencies to or from one another, a service already offered by many platforms, one of the best-known of which is Aave.

The former president's son Donald Trump Jr. touted this as "the start of a financial revolution," during a session streamed on X, formerly Twitter.

Zachary Folkman and Chase Herro, the linchpins of the project and established cryptocurrency entrepreneurs, said the platform would primarily use "stablecoins", which are backed by a traditional currency, most often the dollar.

As a result, they are free from the sometimes brutal fluctuations experienced by digital currencies untethered to real-world money.

World Liberty Financial wants to attract the masses to cryptocurrencies, creating a platform easily accessible to people, Folkman said.

Project leaders said they would sell tokens that give owners the right to take part in governance of the platform, with 63 percent of them offered to the public, 20 percent going to the founding team and the rest set aside as rewards for users.

No timetable for the project was disclosed.

During his presidency Trump referred to cryptocurrencies as a scam, but has since radically changed his position, presenting himself as a "pro-bitcoin president" if elected in November.

In so doing, he is standing in opposition to the Biden administration, which is seen as a proponent of regulating the sector.
