zQuoter:
buildEthArbMulticallExactOut/In(),
buildTokenArbMulticallExactIn(), or single-leg
buildBestSwap(). Use Bootstrap… if the zAMM pool
is missing.
multicall() on zRouter: swap half your ETH
via best of UniV2/Sushi for tokens → addLiquidity() on
zAMM 30 bps with the other half + tokens → sweep dust back to you.
