Colorado is now accepting tax payments in cryptocurrency, as Gov. Polis promised
Colorado is now the only state to accept tax payments in cryptocurrency, Gov. Jared Polis announced Monday at Denver Startup Week.

The American state of Colorado now accepts cryptocurrency for tax payments, Gov. Jared Polis announced on Monday. The option is already available on the state Department of Revenue website.

Colorado tax payments are accepted through the PayPal Cryptocurrency Hub with service fees of $1.00 plus 1.83% of the payment amount. Payments are accepted only from personal accounts in a single cryptocurrency. Businesses cannot pay their taxes via crypto yet. Payments will be effective on the day they are initiated, although it will take three to five days for the transfer to take place. Payments are immediately converted into fiat.

The Colorado governor said earlier this year that he expected the state to begin accepting payment in crypto. Speaking at the opening of Denver Startup Week, Polis said of the new payment option:

“We’re just showing again, from a customer service perspective, how Colorado is tech-forward in meeting the ever-changing needs of businesses and residents.”

Polis is a long-time crypto supporter and aadvocate for the tech industry in his state. As a member of the U.S. House of Representatives, Polis was active in cryptocurrency legislation and was a founding member of the Congressional Blockchain Caucus.

Other states have tried to institute tax payments in crypto. Ohio was the first to do so in 2018, but it suspended the service a year later due to legal complications. New Hampshire tried repeatedly to adopt crypto tax payments, but the bills did not make it out of the state legislature, and states such as Georgia, Illinois and Arizona have considered it.

U.S. cities have shown interest in accepting crypto payments as well. Denver, the capital city, was shown to be one of the leading U.S. cities for crypto hires in 2021.

Draft US stablecoin bill would ban new algo stablecoins for 2 years
The draft bill in the US House could see a two-year ban on creating and issuing new algorithmic stablecoins, and could be voted on as soon as next week.

Draft legislation in the United States House of Representatives would place a two-year ban on new algorithmic stablecoins such as TerraClassicUSD (USTC) which de-pegged from the US dollar earlier this year causing widespread crypto market contagion.

The bill would criminalize the creation or issuance of new “endogenously collateralized stablecoins,” according to a current draft of the legislation obtained by Bloomberg.

However the legislation includes a grace period of two-years for existing algorithmic stablecoin providers to change their models and collateralize their offering differently.

The definition would reportedly cover stablecoins which depend on the value of another virtual asset from the same creator to maintain its price and is marketed as having the ability to be converted, repurchased or otherwise redeemed for a fixed price.

The bill raises concerns over whether stablecoins such as Synthetix USD (SUSD) would be captured by the definition, as it is currently collateralized with the native asset of the same protocol in the SNX token. Other algo-stablecoins with a similar structure include BitUSD which is backed by BitShares (BTS).

The draft bill also mandates the U.S. Treasury to undertake a study on algorithmic stablecoins and consult with the Federal Reserve, the Securities and Exchange Commission, the Federal Deposit Insurance Corporation, and the Office of the Comptroller of the Currency.

It’s possible the panel could vote on the bill as early as next week, Bloomberg reports people familiar with the legislation state Democratic Representative Maxine Waters and Republican Patrick McHenry have been working to reach an agreement on the legislation, although it's unknown if McHenry approved the latest draft.

Waters Chairs the House Financial Services Committee, of which McHenry is a Ranking Member, both heard testimony at a hearing Tuesday that U.S. dollar-backed stablecoins could enhance national security due to the perceived prestige and reliability of the dollar.

TerraClassicUSD (USTC), formerly known as TerraUSD (UST) is an algorithmic stablecoin which lost its 1:1 peg with the U.S. dollar in early May hitting an all-time low of $0.006 in mid-June which resulted in tens of billions of dollars worth of losses.

White hat finds huge vulnerability in ETH to Arbitrum bridge: Wen max bounty?
An ethical, “white hat” hacker found a “multi-million dollar vulnerability” in the bridge between the Ethereum and Arbitrium networks.

A self-described white hat hacker has uncovered a “multi-million dollar vulnerability” in the bridge linking Ethereum and Arbitrum Nitro and received a 400 Ether (ETH) bounty for their find.

Known as riptide on Twitter, the hacker described the exploit as the use of an initializing function to set their own bridge address, which would hijack all incoming ETH deposits from those trying to bridge funds from Ethereum to Arbitrum Nitro.

Riptide explained the exploit in a Medium post on Sept. 20:

“We could either selectively target large ETH deposits to remain undetected for a longer period of time, siphon up every single deposit that comes through the bridge, or wait and just front-run the next massive ETH deposit.”

The hack could have potentially netted tens or even hundreds of millions worth of ETH, as the largest deposit riptide recorded in the inbox was 168,000 ETH worth over $225 million, and typical deposits ranged from 1000 to 5000 ETH in a 24-hour period, worth between $1.34 to $6.7 million.

Despite the earning potential from the ill-gotten gains, riptide was thankful that the “extremely based Arbitrum team” provided a 400 ETH bounty, worth over $536,500, however they added later on Twitter that such a find “should be eligible for a max bounty,” which is worth $2 million.

Neither Arbitrum nor its creator company OffChain Labs have publicly commented on the exploit, Cointelegraph contacted OffChain Labs for comment but did not immediately hear back.

Arbitrum is a layer-2 Optimistic Rollup solution for Ethereum, clustering batches of transactions before submitting it to the Ethereum network in an effort to minimize network congestion and save on fees. Arbitrum Nitro launched on Aug. 31st, an upgrade aimed to simplify communication between Arbitrum and Ethereum as well as increasing its transaction throughput at lower fees.

Similar style bridge hacks have been successful for exploiters this year, notably the $100 million stolen from the Horizon Bridge in June and the recent Nomad token bridge incident in August which saw $190 million drained by the original and “copycat” hackers repeating the exploit.
