Brazilian banks are expanding their cryptocurrency services for customers. According to Folha de S.Paulo, Brazil's largest asset management bank, Itaú, now offers 15 types of cryptocurrencies, including Bitcoin, Ethereum, and the US dollar stablecoin USDC, through its investment app. Brazil's largest fintech company, Nubank, has listed 28 types, and Banco do Brasil, the most profitable state-owned bank in Brazil, has seen transaction volumes exceed 11 million reais (approximately 2.1 million USD) since launching direct purchase services for Bitcoin and Ethereum in January of this year.However, customer cryptocurrency transactions have not entered the banks' balance sheets. A document from the central bank dated March 2026 shows that Brazilian banks hold zero virtual assets on their books. Over the past year, Itaú, Bradesco, Santander, Banco do Brasil, and Nubank have all expanded their cryptocurrency product lines, while the Brazilian cryptocurrency market has also reached record sizes. According to data from the Brazilian Federal Revenue Service, Receita Federal, Brazilians transferred 505.5 billion reais (approximately 98.7 billion USD) through cryptocurrencies in 2025, more than five times that of 2020, with corporate transactions accounting for 98.3%.This move by banks coincides with the implementation of regulations. In 2022, Brazil passed the "Virtual Asset Legal Framework," granting regulatory authority to the central bank. Three resolutions issued in November 2025 require any institution allowing customers to trade, hold, or send cryptocurrencies to obtain a license, meet minimum capital requirements, and segregate customer accounts, with a compliance deadline of October 30, 2026.

Self-proclaimed "white hat hackers" extracted about 4,000 BTC from Liquid Network and have returned 3,400 BTC (approximately $269.2 million) to the federal wallet of the sidechain on Monday, recovering about 85% of the funds. The incident began on Sunday when a customer sent 4,000 L-BTC to SideSwap's peg-out service. The attackers claimed to be "white hat hackers" through Bitcoin transaction messages and demanded that the vulnerability be fixed first. Blockstream then sent a signed message stating that "the bridging node has been patched and funds can be safely returned," after which the attackers transferred the funds. Nevertheless, about 598.5 BTC (approximately $47 million) remains in the related address. Ledger's Chief Technology Officer Charles Guillemet expressed skepticism about the "white hat" claim, stating that if this were a negotiated reward under on-chain crypto contracts, it looked more like extortion. Liquid has disabled the bridging nodes and requested exchanges to suspend L-BTC deposits and withdrawals, but has not yet announced a plan for handling the remaining funds or when normal operations will resume.

The Layer 1 blockchain Harmony, once a major competitor to Ethereum, proposed to shut down its mainnet on Sunday, citing threats from AI entities and nation-state actors as too severe. The Harmony team stated on X that since the mainnet launched in 2019, the community has experienced multiple attacks and transformations, and now it is time to completely discontinue the Harmony network. To mitigate the threats, the team proposed migrating the ONE token to Ethereum and redirecting the issuance of newly minted tokens to its new initiative "The Remix Economy for AI Video."According to the proposal, the migration will determine the allocation of alternative tokens received by each holder on Ethereum based on the ONE balance recorded at the final block of the network (i.e., a snapshot), covering wallets, staked tokens, validator rewards, smart contracts, and centralized exchanges. The alternative tokens will be airdropped to the same wallet address on Ethereum, and exchanges will also migrate to the new tokens. Although the proposal states that holders do not need to submit a claim, multi-signature vaults, liquidity pools, and on-chain applications cannot be migrated, and users are urged to exit all smart contracts by September 10, 2026. Harmony also proposed to pay eligible validators and their delegators in four installments from a pool of $1.372 million, provided that validators maintain their stakes, sign agreements, and serve governance roles.This migration proposal is the latest case of blockchain networks facing increased scrutiny due to attacks. In August of this year, Harmony confirmed it was attacked, with the attackers creating approximately 4 billion unauthorized ONE tokens, prompting the team to release a patch and consider a rollback.

Arkham stated that Wintermute appears to be gradually buying PONS through a time-weighted strategy and speculated that it may be preparing to market make for the token on-chain.PONS is the native token of Pons, a meme coin launch platform on the Robinhood Chain, which is responsible for routing completed fundraising tokens to the Uniswap pool. Arkham's data shows that this holding accounts for approximately 0.48% of the circulating supply of PONS (712.1 million tokens) and 0.34% of the total supply (1 billion tokens). Additionally, 6.46 million and 5.58 million PONS are held in the Uniswap V3 pool and the Uniswap PoolManager contract, respectively.Previously, Uniswap Labs had also purchased PONS tokens, and the Pons project team stated that this move aims to achieve "long-term alignment."
