ordered nonces are clutch because you can invalidate any malicious payloads you may have signed (increment it by a large pseudorandom number)

seaport has this with an incrementCounter() function but it doesn’t have bitpacking

just implemented one that uses bitpacking, 1 SSTORE & to a dirty slot 254/256 writes

oooh, just realized that by using an inverted bitmap for odd words you could reuse the dirty slots for all but the initial two increments

gonna have to file that optimization away for later or punt to @optimizoor
