- The archive rebuilds first-hour tapes from Uniswap v4 Swap events and Arc Transfer logs rather than a third-party trades API.
Field notes
ECHO loads a historical first-hour tape and executes a supplied bonding-curve or Uniswap v4 configuration inside an Arc-Anvil fork. The page says the replay uses recorded Swap events, Arc Transfer logs, and the real chain ID rather than synthetic volume or assumed slippage. Its current archive contains ten young reference hours, and the site warns that results from such a small archive may teach little about mature launch conditions.
