rsETH/wstETH: 72.7% price impact in 108 seconds — what the pool data shows

The Kelp DAO bridge event on April 18, 2026 raised a straightforward question: what did the rsETH/wstETH Uniswap v3 pool actually do during and after it?

We pulled block-by-block pool event data to find out.

Block 24909082 at 20:15:47 UTC is where it shows up. One transaction consumed 3,532,244 gas. The BtoAPrice moved from a stable 1.157 to 4.240. That is rsETH priced at 0.236 wstETH instead of its normal 0.864. A 72.7% price impact in a single block.

Two blocks later, an arb corrected it. Total duration: 108 seconds.

The pool held roughly 952 rsETH and 0.44 wstETH. Total liquidity: about $1.9M. That thinness is what made the move so large. Concentrated Uniswap v3 liquidity is capital efficient under normal flow. Under a large directional transaction, crossing all active ticks moves price non-linearly. The same transaction in a $200M pool would barely register.

The data also shows two high-gas transactions at 19:03 and 20:10 UTC, each consuming over 3.1M gas, visible in the pool event log before the shift.
