BitGo, Polygon Among Industry Giants Pushing Rate Limits After The Largest DeFi Exploit of 2026

A wave of protocol-level security responses followed the $292 million KelpDAO rsETH exploit on April 19, with BitGo, Polygon, and Katana moving swiftly to isolate potential contagion.

The attack drained 116,500 rsETH from Kelp DAO’s LayerZero-powered cross-chain bridge through a forged message that bypassed its Decentralized Verifier Network (DVN) configuration.

Protocols Move to Contain Fallout

BitGo, alongside BiT Global Trust, took down the LayerZero OFT DVNs for Wrapped Bitcoin (WBTC) as a precaution. The firm confirmed that user funds remain secure and pledged to share updates as more information becomes available.

Polygon stated that its chain, Agglayer, and broader ecosystem remain unaffected by the incident. The network noted it has safely processed over $2 trillion to date.

Katana paused the OFT path on Vaultbridge, which relied on a 2/3 DVN setup. Bridging through Agglayer, which verifies with zero-knowledge proofs rather than proof-of-authority multisigs, remained fully available.

Meanwhile, Cyvers CTO and co-founder Meir Dolev revealed that KelpDAO was just three minutes away from losing an additional $100 million. A rapid-response blacklist blocked the attacker before a second attempt could succeed.

Industry Leaders Call for Structural Rate Limits

The exploit has reignited calls for built-in rate limits across DeFi protocols. Ethena contributor Guy Young argued that asset issuers should implement throttled cross-chain transfers on top of standard LayerZero OFTs.

“We built a solution on top of the standard OFT to throttle cross chain transfers at $10m per hour for every DVN, in addition to the $10m per block rate limit on the mint contract. The former would have prevented Kelp, the latter Resolv,” he wrote.

Ethena’s configuration caps potential damage at $10 million per chain per hour even if a DVN is fully compromised. Young called the slight inconvenience for users a worthwhile tradeoff to avoid catastrophic losses.

Keone Hon, CEO and co-founder of Monad, proposed that pooled lending protocols adopt “smart caps” that limit how quickly collateral supply can grow.

He pointed to the Resolv hack in March, where the attacker minted infinite tokens but could only extract $24 million because exit pathways were small.

Hon argued that high supply caps should be seen as a liability, not a sign of stature. A supply limit slightly above current utilization, adjusting over hours to the true cap, would have saved rsETH depositors $200 million, he estimated.

The KelpDAO breach is now the largest DeFi exploit of 2026. Whether protocols adopt the rate-limiting measures these leaders are proposing may determine how large the next one gets.

Stablecoins Do Not Threaten Banking Just Yet: Analyst

Stablecoins Do Not Threaten Banking Just Yet: Analyst

The impact of stablecoins on the banking sector appears “limited” at the current phase of the adoption cycle, but banks could face increasing competition and an erosion of market share as the stablecoin sector and tokenized real-world assets (RWAs) grow in market capitalization. 

“So far, the use of stablecoins remains limited, but their market capitalization exceeded $300 billion at the end of last year,” Abhi Srivastava, associate vice president of Moody’s Investors Service Digital Economy Group, told Cointelegraph.

The role of stablecoins in payments, cross-border commerce and onchain finance is “expanding,” despite their currently limited role, Srivastava said, adding that existing payment systems in the US are already “fast, low-cost and trusted.” He said:

“For the banking sector, at this stage, disruption risk appears limited. In the near term, US rules that prohibit stablecoins from paying yield mean they are unlikely to replace traditional deposits at scale domestically.”

However, over time, growing adoption of stablecoins and tokenized RWAs, traditional or physical financial assets represented on a blockchain by a token, could place “pressure” on the banking sector, leading to deposit outflows and reduced lending capacity, he said.

Stablecoin regulatory policy has become a hot-button issue among crypto industry executives and those in the banking sector, with fears that yield-bearing stablecoins could erode banking market share proving to be a stumbling block for the CLARITY crypto market structure bill in Congress.

CLARITY Act stalled, as banks fight yield-bearing stablecoins

The Digital Asset Market Clarity Act of 2025, also known as the CLARITY Act, is a comprehensive crypto market regulatory framework that establishes an asset taxonomy, regulatory jurisdiction and oversight over the crypto markets.

It is now stalled in Congress after a group of crypto industry companies, led by cryptocurrency exchange Coinbase, publicly stated opposition to earlier drafts of the bill.

A lack of legal protections for open-source software developers and a prohibition on yield-bearing stablecoins were among some of the most contentious issues cited by crypto industry opponents of the legislation.

Several attempts have been made by US lawmakers and the White House to negotiate a bill acceptable to both the crypto industry and the bank lobby.

Earlier this month, North Carolina Senator Thom Tillis said he plans to release an updated draft bill proposal that would be acceptable to both sides; however, the bill has reportedly received pushback, according to Politico, and has yet to be publicly released. 

However, other crypto industry executives and market analysts have warned that if the CLARITY Act fails to pass, it could open the crypto industry up to future regulatory crackdowns by hostile lawmakers and officials.
