Sell pressure over time
Cumulative inventory liquidated, in WETH, by simulation step.
The slope reflects the aggregate selling intensity across all recipients.
Realized USDC per step
Per-step revenue summed across all recipients. Gaps indicate steps where
no recipient sold (small rounding amounts below the dust threshold).
Effective realized price
USDC received per WETH sold, per step.
A declining line indicates accumulating slippage from sustained selling.

Methodology
Execution: All token operations execute against actual Solidity bytecode
deployed at the pinned mainnet block via revm (Rust EVM). No Python re-implementation
of pool math — slippage and routing match what would have happened on-chain at that block.
Fork pinning: Mainnet state is fetched once at block
19,000,000. The fork captures token balances, pool reserves, oracle
states, and contract code as they were at that block.
Agent population: 10 heterogeneous recipients with urgency
parameters sampled via seeded RNG (seed=0). Same seed + same fork block produce
byte-identical results.
Pool: WETH/USDC 5.00% pool (Uniswap V3, fee tier 500bps).
What is NOT modeled: external arbitrageurs restoring price between
recipient sells; cross-pool routing through aggregators (1inch / CoW); sandwich attacks
from other MEV searchers; off-chain venues (CEX hedging); recipient behavior changing
in response to observed price impact.
Engine validation: Mayavi’s execution kernel has been validated
bit-exact against the on-chain Uniswap V3 Quoter at the pinned block.
Every swap our engine produces matches what the official Uniswap simulation contract
produces — zero delta. Reproduce locally with mayavi validate.
