Four synced replays. One tape. One survivor.
Load two to four rehearsals from this session and watch them synchronized against the identical trade tape — same buyers, same blocks, different configs. Designate the one that endured.
Open ComparisonThe Fork Is Not a Guess
Arc-Anvil replays every Swap event and EIP-7708 log exactly as it occurred in the first sixty minutes of each reference launch. Your bonding curve or v4 pool contract runs on-chain inside the fork; the only variable is the config you supply.
2. arc-anvil fork (real chain id)
3. Uniswap v4 pool / curve executes
4. price trace + sniper share
Ten recorded first hours, block by block
Each reference tape is rebuilt from Uniswap v4 Swap events and Arc Transfer logs — not a third-party trades API. New tapes are added weekly as more Arc launches complete their first hour.
Recent Rehearsals
Every run is stored under your session. Return any time to load a prior config as baseline and test incremental changes against the same tape.
Two honest limits
Arc is a new chain. Ten past launches today means ten small, young first hours — a config tuned against a near-empty tape teaches less than a mature one.
Sniper concentration shown in a run is computed directly from the real, already-recorded buyers of that historical hour. o1 launches on Arc currently carry no anti-snipe surcharge — so on a hypothetical future launch that number would be a guess, and ECHO never shows one.
Stamp a survivor. Export a reproducible config.
Designating a survivor exports a signed JSON payload containing the exact config and the reference tape id — so anyone can reproduce your rehearsal with the same tool.
