Mercado Bitcoin to Add SUI, USDC and USDsui in Brazil, Plans Tokenized Assets on Sui

Mercado Bitcoin, the Brazilian crypto exchange with 4.5 million clients, is adding SUI, USDC and USDsui, the Sui Foundation said Thursday. The foundation said the move makes Mercado Bitcoin the first exchange in Brazil to support Sui asset transfers, which would let clients buy, sell, send and receive assets on Sui.

The two sources differ on timing. The foundation's announcement says the exchange "will integrate" and "will offer" the three assets, while Sui's official account said Thursday that Mercado Bitcoin's clients "can now" buy, sell, send and receive them. SuiWire did not find an announcement from Mercado Bitcoin at publication and could not independently confirm that the listings are live.

USDsui as lending collateral

The foundation said USDsui, the Sui Dollar stablecoin, will be accepted as collateral in Mercado Bitcoin's lending product.

Hashi and tokenized assets

The companies are exploring how Hashi, Sui's native Bitcoin finance layer, could be incorporated into Mercado Bitcoin's existing lending products. The announcement says any product built on this integration would be subject to Mercado Bitcoin's internal governance and Brazilian regulation, and that no offering is available at this time.

Mercado Bitcoin will also bring its tokenized real-world asset platform onto Sui, according to the foundation. The platform has issued more than 800 tokenized assets since it began tokenization in 2019, covering instruments such as receivables, structured credit, consortium quotas and real estate. No date for the move was given.

Licenses and payment rails

The foundation said Mercado Bitcoin holds 10 regulatory licenses across Brazil and Europe, including authorization from the Central Bank of Brazil as a payment institution and from the Brazilian Securities and Exchange Commission (CVM) as a securities broker. As a payment institution, it is integrated with Pix, Brazil's instant payment system, which lets clients convert between Brazilian reais and dollar-denominated stablecoins in real time.

The exchange is also building cross-border rails into the US and Portugal. It is registered with the Banco de Portugal for exchange and custody services and operates a licensed business there, Mercado Bitcoin Portugal, which has a MiCA application in progress.

"Millions of people across Brazil now have access to Sui through Mercado Bitcoin," said Roberto Dagnoni, chairman of Mercado Bitcoin and CEO of 2TM, Mercado Bitcoin's parent company.

Adeniyi Abiodun, co-founder and chief product officer of Mysten Labs, called Brazil "key to Sui's next phase of sustained growth."

Why it matters

The deal would give Sui a regulated route between Brazilian reais and onchain assets through one of the country's largest crypto platforms. The lending collateral role for USDsui and the planned tokenized assets would extend Sui's use in Brazil beyond trading.
