Circle Launches Arc: What the Stablecoin-Specific Chain Means for the Market
What Is Arc? Why USDC as a Native Gas Token Is Worth Attention
Circle has launched its stablecoin-specific blockchain Arc, which uses USDC as the native gas token. According to Decrypt, using USDC as a gas token could change the transaction cost structure for users interacting with on-chain applications, but the report did not provide specific parameters such as fees, throughput, or supported wallets; these must be confirmed with Circle's official technical documentation.
Our independent assessment: If Arc receives sustained investment from major stablecoin issuers, it could strengthen USDC's infrastructure position in on-chain payment and settlement scenarios, but it is still in an early ecosystem stage, with both technical and regulatory risks.
How OKX Users Can Verify Whether USDC Deposits and Withdrawals Are Affected
As an independent third-party media outlet, OKX Radar does not pre-fill OKX's support status for the Arc chain. Users should check OKX's official announcements to confirm whether USDC deposit and withdrawal channels on the Arc network are open and whether there are additional tag or contract address requirements.

Clarity Act Fails: Senate Vote Results and Crypto Stock Reactions
Vote Details: 50 For, 49 Against, Below the 60-Vote Threshold
The US Senate cloture vote on the Clarity Act ended with 50 votes in favor and 49 against, falling short of the 60 votes needed to advance. According to Yahoo Finance on September 16, 2026, this means the bill failed to move forward in this procedural vote, but it does not mean the legislative path is over; it may still be amended or reintroduced later.
Crypto Stocks Rise in Early Trading: Coinbase, Strategy, Robinhood Performance and Interpretation
In early trading after the vote failed, Coinbase shares rose 1% to $174, Strategy rose 1% to $130.66, and Robinhood rose 0.57% to $111.08. The same Yahoo Finance report showed this performance.
| Stock | Early Price | Change |
|---|---|---|
| Coinbase | $174 | +1% |
| Strategy | $130.66 | +1% |
| Robinhood | $111.08 | +0.57% |
Independent researcher perspective: The rise in crypto stocks may be related to the temporary removal of regulatory uncertainty, but it should be interpreted in conjunction with the day's overall market and sector performance, and cannot be simply attributed to a single event. We recommend reading Before the Key Procedural Vote on the CLARITY Act: Democratic Counter-Proposal, 18 State Attorneys General Opposition, and SEC/CFTC Regulatory Division Interpretation for background on the vote.
Fed Expected to Raise Rates by 25 Basis Points: Decision Probability and Crypto Market Volatility
CME FedWatch Shows 92% Probability of Rate Hike to 3.75%-4.00%
CME FedWatch showed a 92% probability that the Federal Reserve would raise rates by 25 basis points that day, potentially moving the target range from 3.50%-3.75% to 3.75%-4.00%. According to a Yahoo Finance report on September 16, 2026, before the decision, this was pre-decision data; the final outcome must be confirmed with the FOMC's official policy statement.
Pre-Decision BTC, ETH, XRP Price Performance and Macro Transmission Logic
Before the Federal Reserve's interest rate decision, Bitcoin was around $75,903, down 1.44% over 24 hours; Ethereum was around $2,404, down 3.18%; XRP was around $1.29, down 7.98%. Data from the same Yahoo Finance report.
| Asset | Pre-Decision Price (approx.) | 24h Change |
|---|---|---|
| BTC | $75,903 | -1.44% |
| ETH | $2,404 | -3.18% |
| XRP | $1.29 | -7.98% |
Rate hike expectations typically increase the attractiveness of dollar-denominated assets and may put pressure on risk asset valuations, but the crypto market is also influenced by other factors.

How OKX Users Can Comprehensively Assess the Three Developments and Prepare
Impact of Overlapping Events on Crypto Asset Risk Appetite
Circle Arc could affect stablecoin infrastructure, the Clarity Act's failure temporarily eases regulatory pressure, and the Fed's rate hike tightens liquidity; the three developments point in different directions and need to be assessed comprehensively. Our independent assessment: The three developments have not yet formed a single-direction market trend, and short-term volatility is more likely to come from shifts in liquidity expectations and risk appetite.
Verification Checklist and Risk Control Before Taking Action
We recommend OKX users verify the following steps to avoid making decisions based on a single event:
- Verify Circle's official announcements and Arc technical documentation to confirm the USDC native gas mechanism, contract addresses, and cross-chain risks.
- Check OKX's official announcements to confirm whether the Arc network and USDC deposit/withdrawal channels are open and whether there are new address tag requirements.
- Record time series of crypto stock and crypto asset prices, compare with the broader market and sector performance, and avoid attributing stock price fluctuations solely to a single vote result.
- Monitor the original FOMC policy statement and CME FedWatch updates to check the final interest rate range against market expectations.
- Check price volatility, market depth, compliance announcements, and risk warnings in the trading interface, and manage position size and leverage.
Note that USDF stablecoin is a different stablecoin concept from Arc and must be distinguished in writing and reader understanding; specific details about USDF require further verification and are not expanded upon in this article.

Frequently Asked Questions
After Circle Arc goes live, will USDC deposits and withdrawals on OKX change?
Currently, the input materials do not include an official statement from OKX on Arc chain support status, so it cannot be confirmed. Users should search for "Arc" or "USDC deposit/withdrawal" keywords on the OKX official announcements page to check whether there are new networks, tag addresses, or suspension notices; do not act solely based on third-party news.
Does the Clarity Act's failure mean US crypto regulation will become stricter or looser?
This failure only means the procedural vote did not reach 60 votes; it does not mean the bill has permanently failed or that the regulatory direction is set. According to Yahoo Finance on September 16, 2026, the vote was 50 in favor and 49 against; the bill may still be amended or reintroduced later, and the regulatory direction needs continued monitoring.
