A practical checklist for MegaETH: KYC on Echo, USDT deposit, bid sizing, lock math, and post‑sale moves that actually matter!

Most sale posts repeat the facts. Useful, but thin. This walkthrough adds:

• Decision trees for different bankrolls.

• Bid-sizing recipes (with simple numbers you can copy).

• Failure mode playbook when KYC or deposits stall.

• Lock-or-not rules of thumb with breakeven math.

• Checklist you can finish in 15 minutes before the auction opens.

Use the official MegaETH Public Sale page for actions.

• Format: 72‑hour English auction; one clearing price for all fills.

• Currency/chain: USDT on Ethereum.

• Band & caps: price band is tight; per‑user min and max exist; KYC is required.

• Lock option: 1‑year lock grants 10% discount on your executed price.

• Post‑sale: there’s a withdrawal right window; TGE happens ≥40 days after the sale ends.

This isn’t a “fastest finger” mint. It’s a sizing, patience, and discipline test.

1. Documents: ID + proof of address (≤90 days). Clean scans; full edges visible.

2. Wallet: one EVM wallet you control. No last‑minute switching.

3. Funds: USDT (ETH mainnet) + gas cushion. Send a tiny test tx today.

4. Registration: run the Echo/Sonar KYC flow to a Qualified status.

5. Alerts: create start/end reminders; add a 3‑hour-before nudge to re‑check your bid.

If any of these feel shaky, fix them now. Auction windows feel long until the last 30 minutes.

• POA rejections usually come from cropped edges, glare, or missing issue date. Re‑scan, don’t resubmit the same file.

• Name mismatch between ID and platform profile can trigger manual review. Match the formats.

• Liveness fails increase with low light and front‑camera smudges. Clean lens, neutral background.

• Address changes in the past 60–90 days? Use a bank/utility statement with your current address.

• VPN/proxy during KYC can add friction. If possible, avoid it.

Goal is Qualified before the sale goes live. Anything pending at T‑0 is stress you don’t need.

Pick one that matches your bankroll and risk tolerance. Adjust numbers to your limits.

1) The Baseline Participant

• Objective: get an allocation without overpaying.

• Action: place a mid‑band price and the amount you’re comfortable with at T‑0+1h.

• Maintenance: add funds or nudge price once in the last 6–12 hours if demand looks heavy.

• Why: keeps gas costs low and avoids emotional edits.

2) The Price‑Sensitive Bidder

• Objective: prioritize effective entry price.

• Action: set a conservative price early, monitor the book, and be ready to step up only once near the end if fill looks borderline.

• Maintenance: strictly avoid chasing in the last 5 minutes (fees spike; mistakes happen).

• Why: protects you from top‑tick edits.

3) The Lock‑Enabled Accumulator

• Objective: long‑term size with better cost basis.

• Action: set your target amount, then toggle 1‑year lock for some or all of it.

• Maintenance: you can split 70/30 unlocked/locked and update later if conviction increases.

• Why: the 10% discount compounds if your horizon is 12+ months.

Keep it simple. Here’s a minimal toolkit.

• Executed price is the clearing price (not your bid).

• Tokens received = your_USDT / clearing_price.

• Locked discount = clearing_price × 0.9 effective price for the locked portion.

• Breakeven for lock: you must believe your opportunity cost < 10% of principle over one year to justify the lock.

Example: clearing price ends at $0.045.

• You deposited $5,000 → 111,111.11 MEGA.

• If you lock 100%, effective price is $0.0405 → you “save” $555.55 versus unlocked.

• If you lock 50%, blended effective price ≈ $0.04275.

• Batch edits beat drip edits. Every change costs gas and attention.

• Don’t edit in the final minutes unless you’ve rehearsed fees and contracts. Congestion is a thing.

• Respect your cap. If you hit the cap, you can’t add more; don’t burn time wrestling with it.

• Sanity check the USDT token contract and network each time.

• Yes, if: you’re here for the product, can park capital 12 months, and value the –10% effective price.

• Maybe, if: your thesis is strong but you want partial liquidity. Split the order (e.g., 60/40).

• No, if: you need flexibility around TGE or you’re trading around early liquidity.

Remember: lock starts at TGE, not today.

1. Review allocation at settlement. Screenshot it.

2. Decide on withdrawal during the withdrawal right window (full refund vs keep allocation).

3. Track TGE (≥40 days post‑sale). Add a reminder.

4. Post‑TGE ops: manage lock schedule (if enabled) and security hygiene (hardware wallet, allowlist management).

• KYC stuck: resubmit with a different, higher‑quality file; ensure metadata (name/address) matches exactly.

• Deposit missing: confirm you sent USDT on Ethereum mainnet to the correct address; check block explorer; wait for confirmations.

• Wrong wallet: if you bid from a non‑registered wallet, contact support immediately; expect limited options.

• Price below band: re‑enter within the allowed range; don’t fight the form.

• Cap hit early: consider leaving the price where it is; incessant price chasing near the end is error‑prone.

• Open the official MegaETH sale dashboard; verify balances and bid.

• Re‑read the price band and your cap.

• Decide whether to toggle or expand the lock portion.

• Check gas conditions; don’t do last‑second heroics.

• Take a final screenshot of status and tx links.

No. Everyone who qualifies pays the clearing price.

No platform subscription or offer fee; standard gas only.

There’s a withdrawal right window (full refund; tokens forfeited).

At TGE, which is at least 40 days after the sale ends.

No. Optional. It’s just a pricing lever.
