El Salvador has become the first country to adopt bitcoin as legal tender.

Lawmakers in the Central American country’s Congress voted by a “supermajority” in favor of the Bitcoin Law, receiving 62 out of 84 of the legislature’s vote.

The price of bitcoin was up 5% to $34,239.17 shortly after the vote.

Earlier on Wednesday, President Nayib Bukele sent the law to to the country’s Congress for a vote.

“The purpose of this law is to regulate bitcoin as unrestricted legal tender with liberating power, unlimited in any transaction, and to any title that public or private natural or legal persons require carrying out,” the law reads.

Prices can now be shown in bitcoin, tax contributions can be paid with the digital currency, and exchanges in bitcoin will not be subject to capital gains tax.

Bitcoin is known for wild price swings that have prompted critics to suggest it is not suitable to be an effective currency. It’s still unclear how El Salvador will ultimately roll out bitcoin as legal tender.

The exchange rate with the U.S. dollar “will be freely established by the market,” according to the proposed law. El Salvador’s current official currency is the U.S. dollar.

The law also says that the state will “promote the necessary training and mechanisms so that the population can access bitcoin transactions.”

Approximately 70% of El Salvador does not have access to traditional financial services, according to the Bitcoin Law. The cryptocurrency is seen as a way to increase financial inclusion.

The proposal will need to go through El Salvador’s legislative process before being passed as law.

Bukele’s move to submit the law to Congress comes after he announced last week that El Salvador has struck a partnership with digital wallet company Strike, to build the country’s modern financial infrastructure using bitcoin technology.

In April, bitcoin hit a record high of $64,829.14, but has since dropped by nearly half, according to CoinDesk data. It is still up over 230% over the last 12 months. That rise has been attributed to a number of factors including rising interest from institutional investors and large companies such as Tesla and Square buying bitcoin.
