According to ChainCatcher, Electric Capital's latest research report reviewed 501 real-world revenue sources and found that only 34 of them have on-chain scales exceeding $50 million, mainly concentrated in US Treasury bonds, private credit, and corporate bonds.

The report pointed out that distribution channels are the biggest bottleneck. Among the 35 non-stablecoin RWAs with on-chain revenue, only two have more than 2,000 holders, and the top assets are highly concentrated. For example, in BlackRock's BUIDL, the top ten holders control 98% of the supply.

NYSE completes rule change to remove trading limits on crypto ETF options

According to ChainCatcher, as reported by The Block, NYSE Arca and NYSE American have submitted a rule change to the SEC to remove the 25,000 contract holding and exercise limits on spot Bitcoin and Ethereum ETF options.

The US Securities and Exchange Commission (SEC) waived the standard 30-day waiting period for these two documents, allowing the changes to take effect immediately after submission, marking that all major options exchanges in the US have completed this adjustment. The rule change covers 11 crypto ETF products, including BlackRock IBIT, Fidelity FBTC, ARK 21Shares ARKB, Grayscale Bitcoin and Ethereum Trusts, and Bitwise's Bitcoin and Ethereum ETFs. These products can now determine position limits according to the standard framework of each exchange, with large liquidity ETFs eligible for limits of 250,000 contracts or higher.

This move helps institutional investors implement hedging strategies and basis trading more efficiently. In addition, the Nasdaq ISE exchange has submitted a proposal to increase the exclusive options position limit for IBIT to 1 million contracts, which is still under review by the US SEC. If approved, this proposal will bring IBIT's position size closer to that of the largest stock ETFs. The comment period for related documents will end on April 13.

Polymarket updates market integrity rules, explicitly prohibits three types of insider trading behaviors

According to ChainCatcher, Polymarket announced today that it has updated its market integrity rules for its DeFi platform and the US exchange regulated by the Commodity Futures Trading Commission (CFTC).

The updated rules clarify three core prohibited insider trading behaviors:

Trading using stolen confidential information - Participants may not trade any contracts if they possess confidential information about the outcome or potential outcome of the underlying event and using that information would violate a pre-existing trust or confidentiality obligation owed to others or entities.

Prohibition on trading using illegal insider information - Participants may not trade using confidential information provided to them by others if that information was provided by someone who owes a prior trust or confidentiality obligation to others, and the participant knows or has reason to know that the person providing that information would be prohibited from trading on that information.

Trading by those who can influence the outcome - Participants may not engage in any contract trading if they have the authority or influence sufficient to affect the outcome of the underlying event.

SIREN's actual control ratio may reach 88.5%, controlled by DWF Labs

According to ChainCatcher, monitoring by Yu Jin shows that among the top 54 addresses holding SIREN tokens, except for the burn wallet and Binance Web3 wallet, the remaining 52 addresses are suspected to be owned by the same controlling party, with 48 of them being addresses that previously concentrated SIREN, and the other 4 addresses' SIREN can be traced back to purchases made from late June to early July last year. This controlling party holds a total of 644 million SIREN, accounting for 88.5% of the total, valued at $1.44 billion.

Yu Jin pointed out that the controlling party profits by controlling almost all spot and using contracts, which is the reason for SIREN's 30-fold increase in a month and a half.

Paul Frambot advised users to continue to pay attention to communications and updates from Resolv Labs and related Curators for the latest developments on specific vault risk exposures. Katana, incubated by Polygon, acquires IDEX and launches new Perps product

Electric Capital: Tracking 501 revenue-generating RWA assets, we discovered these patterns

From private credit to GPU leasing, from catastrophe bonds to music royalties, tokenizable assets are far richer than the market recognizes. However, the biggest challenge is not technology, but distribution—existing RWAs heavily rely on a few large deployers, and concentrated risks cannot be ignored. Controlling distribution channels may become an irreplaceable infrastructure for the distribution layer, representing the two most competitive entrepreneurial paths currently.

The stablecoin yield battle: How has it stalled US crypto regulatory legislation?

This legislation, supported by the president and aimed at establishing more comprehensive regulatory rules for the US cryptocurrency market, is approaching a political deadline at the congressional level. Meanwhile, the banking industry is pressuring lawmakers and regulators to prohibit stablecoin companies from offering yields similar to bank deposit interest.

This game has become one of the most core unresolved issues in Washington's crypto agenda. The focus of the controversy is: should stablecoins pegged to the dollar focus on payment and settlement functions, or can they increase their financial attributes to compete with bank accounts and money market funds?

The Senate's market structure bill, named the "CLARITY Act," has stalled due to a breakdown in negotiations surrounding the so-called "stablecoin yield."

Industry insiders and lobbyists indicate that if the bill is to have a realistic chance of passing before the election year's schedule tightens, the actual window for advancing the bill will be from late April to early May.
