ECHO

$ECHO is an on-chain fee cycle powered by a Uniswap v4 hook. Every buy enters the active echo. When new buyers enter after you, their fees flow backward through earlier positions. The earlier you entered the current echo, the more future buys can reflect through your position. But the echo does not last forever. A sell clears the active cycle and resets the echo. After the reset, the next buy starts a fresh echo from zero. Buyers enter. Fees flow back. Earlier positions earn. A sell clears the cycle. Then the next echo begins. Every buy leaves an echo. Every sell resets it.
