Mantle’s October 2026 restaking boom and EigenLayer myths

ether.fi will sever its final structural ties to EigenLayer this quarter. less than 1% of its assets still participate in restaking. Mike Silagadze, the ether.fi CEO, stated that no meaningful yield opportunities exist in the restaking sector. In August, the project decoupled restaking functionality from weETH. weETH now functions as a standard liquid staking token. In 2024, user deposits of ETH were automatically restaked on EigenLayer. DefiLlama data from September 8 shows the restaking sector held $10.02 billion in TVL. This sector generated only $99,977 in fees over the previous week. In contrast, the liquid staking sector held $51.87 billion in TVL and generated $27.35 million in weekly fees. Standard staking generates 53 times more yield than restaking for assets of equal size. The top five liquid restaking protocols – Renzo, Kelp, Swell, Puffer Finance, and Bedrock – generated a combined gross profit of only $953,300 in Q2 2026. This figure reflects a significant drop from the $2.18 million they earned three quarters prior. Puffer Finance reported a quarterly gross profit of just $21,590 despite raising $23 million. Swell reported a similar figure of $22,370 for the same period. The profitability of these protocols depends entirely on basic staking fees.

The technology is not the problem

The technology behind EigenLayer does not fail. EigenDA achieves mainnet throughput of 100MB/s. The service maintains the largest secured asset footprint in the industry. The Kelp DAO cross-chain bridge exploit in April 2026 allowed attackers to mint 116,500 rsETH worth approximately $293 million without any underlying ETH backing, and these counterfeit tokens enabled withdrawals of roughly $6 billion from Aave within days. This event was a failure of the bridge, not the core EigenLayer protocol. EigenLayer itself experienced no slashing events through May 2026. The core restaking mechanism remains intact.

Slashing and concentrated risk

Slashing turned theoretical risk into tangible losses in April 2025. EigenLayer activated slashing to penalize validators for infractions. Liquid restaking token holders face even more complexity. They assume additional layers of smart contract risk. EigenLayer holds 94% of the restaking market. This concentration means an exploit there causes a systemic event. You should realize that LRTs do not protect you from the slashing of the underlying validators.

The risk in liquid restaking tokens grows with every added service. Each Actively Validated Service adds its own slashing conditions to the same stake. If an operator fails to meet its obligations, the protocol confiscates a portion of the staked ETH. This penalty can wipe out years of extra yield in a single event. Puffer Finance and Swell follow a model where EIGEN token rewards are fully distributed to depositors. This leaves zero profit for the protocols.

Capital shifts to USD and curated vaults

Capital withdrawn from the restaking sector did not leave the crypto lending market. It shifted from ETH assets to USD-denominated assets. Curated vaults like Morpho hold $5.8 billion in TVL. On November 4, 2025, Stream Finance disclosed losses of approximately $930 million. Its yield-bearing USD stablecoin, xUSD, dropped 77% in one day. The market priced xUSD at a fixed $1 instead of its true market value. Why did the market price xUSD at a fixed $1 despite the obvious divergence in value?

The migration to stablecoin-based products and curated lending pools suggests a search for stability. In 2024, the mainstream strategy involved leveraging ETH-denominated liquid restaking tokens. By 2026, users prefer vaults where third-party managers set the risk parameters. Mantle provides a different market context as users look for Layer-2 alternatives. MNT trades in a constructive trend but remains 78.74% below its October 2025 high of $2.86. The market shows no sign of returning to the massive restaking volumes of 2024.

ether.fi redirected its focus to neobanking to offset these losses. Its consumer card revenue rose from 17% in January to 46% in July. The company expects annualized revenue to increase by 38% this year. This growth comes as staking and restaking income declined by 70%. The shift to tokenized stocks and metal assets via Aave shows the direction of the industry. The restaking era ended not because the technology failed, but because the math stopped working.
