10 Major Crypto Events, From Stablecoin Rules to Wallet Security

October 2026 brought two competing developments: banks and regulators advanced digital asset infrastructure, while security incidents exposed weaknesses in exchanges and wallets. These ten events show why the industry deserves attention beyond token prices. This review covers October 1–31 and groups events by theme.

1. Binance faces a major security breach

Between October 29 and 31, the Binance breach dominated crypto headlines. Forbes reported an estimated $6.3 billion impact, with roughly $3 billion frozen through partners. Binance pledged to cover losses with SAFU and company funds. Frozen assets are not necessarily recovered assets, and compensation promises should be distinguished from completed payments. Users have reason to review how they separate trading balances from long-term holdings.

2. The OCC finalizes stablecoin implementation rules

On October 23, the Federal Register published the OCC’s final GENIUS Act rule covering payment stablecoin issuance and related activities within its jurisdiction. It takes effect on January 18, 2027. Reserve management, redemption, risk controls and licensing receive clearer requirements. For stablecoin users, identifying the issuer and understanding redemption rights become increasingly important.

3. JPM Coin expands to Ethereum

On October 19, Kinexys announced that JPM Coin, ticker JPMD, had reached Ethereum after its earlier deployment on Base. The dollar deposit token remains available to approved institutional clients rather than ordinary retail buyers. Its expansion illustrates growing bank use of public blockchains, but a tokenized bank deposit should not be confused with a retail stablecoin or investment token.

4. Standard Chartered signs a Zodia Custody acquisition agreement

On October 21, Standard Chartered signed definitive agreements to acquire Zodia Custody, with plans to integrate its regulated custody operations into Securities Services. Regulatory approvals and closing conditions still apply. The deal advances bank participation in crypto safekeeping. Users should nevertheless examine asset segregation, withdrawal rights and contractual responsibility rather than relying on a banking brand alone.

5. Solana activates Alpenglow

On October 21, Solana’s mainnet-beta activated Alpenglow, replacing TowerBFT and moving validator votes off-chain. Anza targets finality of roughly 150 milliseconds. That protocol target is not a guarantee that every wallet transfer will appear or settle that quickly. Wallet software, RPC services and application processing still shape the experience users see.

6. Switzerland approves its first domestic retail Bitcoin ETF

On October 20, FINMA announced approval of Switzerland’s first retail ETF investing directly in Bitcoin. It emphasized custody safeguards, operational controls and clear sales disclosures. Approval broadens regulated access without removing Bitcoin’s market risk. Owning fund shares also differs from holding on-chain bitcoin that can be withdrawn to a personal wallet.

7. BlackRock files for a managed-protection Bitcoin ETF

An October 19 filing proposed the iShares Bitcoin Managed Protection ETF, with expected ticker PBIT. Its options strategy seeks limited upside exposure and a degree of downside protection. A filing is not approval or a trading launch. Return caps, purchase timing and fees affect outcomes, and the protection language does not guarantee preservation of capital.

8. France advances a stablecoin tax amendment

On October 7, the French National Assembly’s Finance Committee adopted amendment I-CF1826. It proposes changing tax deferral for swaps into electronic-money tokens as defined by MiCA, with application from January 1, 2027. Committee adoption is not final enactment. The proposal reinforces why users should retain acquisition costs and transaction histories even when they exchange crypto for stablecoins rather than cash.

9. Bitcoin Core discloses a non-Linux node vulnerability

On October 28, Bitcoin Core disclosed CVE-2026-117350. Malicious peers could use TCP urgent data to exhaust memory on affected non-Linux nodes. The advisory lists fixes in versions 29.5, 30.4, 31.2 and 32.1. This is a node availability issue; it should not be described as a theft of Bitcoin private keys or network-wide holdings.

10. Fearless Wallet extension users receive a key-leak warning

On October 21, the Polkadot Community Foundation warned that Fearless extension versions 3.0.1, 3.0.3, 3.0.4 and 3.0.5 contained code that transmitted private keys. Affected users were instructed to generate new keys in another well-maintained wallet and move funds. Switching apps, reinstalling or changing a password cannot make an exposed key safe again.
