The Survival Challenge in L2

Layer 2 solutions are entering a phase where survival will depend less on speed or marketing and more on whether networks can responsibly manage liquidity, performance, and counterparty risk, according to Bitlayer co-founder Charlie Yechuan Hu.

On the margins of the Breakpoint event, Hu pointed out that recent months have shown that “it’s no longer about being the fastest L2.” Several partners with whom Bitlayer worked “could not manage their financial parts healthily,” leading to operational halts and unrecoverable liquidity.

Hu highlighted the October 11 liquidation event, when around $20 billion in market-level liquidity evaporated, as the moment many protocols were exposed. “Some protocols became insolvent. They cannot pay their debts, cannot pay yields,” he stated.

Risk Assessment as the New Benchmark

Hu emphasized that the growth of Bitcoin DeFi has been uneven, describing the ecosystem as “a zigzag journey.” The central challenge is not transaction performance but solvency: how L2s support performance, evaluate counterparts, and protect wrapped BTC collateral.

“We need to ensure we work with the right partner on performance. Otherwise, it becomes uncollectible debt,” he said. In his view, Bitcoin L2s must now adopt disciplines more akin to traditional credit markets than crypto experiments.

“It’s about being safe, sustainable, achieving real yields… and having the right system for risk assessment,” he explained.

Liquidity Fragmentation and Bridge Security

Liquidity fragmentation among dozens of emerging Bitcoin L2s is another risk that Hu believes the industry underestimates. Most Bitcoin remains inactive in cold storage, and responsibly activating it is far more important than multiplying new networks.

“We are still in the early stages of activating Bitcoin liquidity,” he noted, adding that several L2s have already shut down, indicating an early consolidation phase.

Hu also highlighted widespread misunderstandings around bridge security. WBTC, despite its popularity, relies on a custody multisig controlled by a small group of entities, a scheme Hu described as increasingly risky. In contrast, Bitlayer’s verifier model allows any operator to challenge a malicious transaction.

“Bitcoin security requires fees… miners need a new source of income,” he said, arguing that L2s should share value with miners rather than becoming isolated alternative ecosystems.

Sustainability as a Defining Factor

Hu stated that the central issue shaping the next wave of Bitcoin L2s will be that networks treating liquidity as a balance sheet responsibility rather than a marketing metric will be the ones to endure.

“The journey of Bitcoin DeFi has not been easy. But now it’s about sustainability.”
