Overview
Blockra is a token scanner for Robinhood Chain (chain id 4663) that stands behind its own calls. Paste a token, and seven fixed-rule checks read public chain data and seal one verdict: SOLID, CRACKED or BROKEN. A public paper desk then trades on those verdicts, and its balance is the honest record of how often the scanner was right.
Nothing asks for a wallet, a signature or a key. Every desk trades paper money against real prices.
The seven checks
The score starts at 100. Each check can take points off, and the reason for every lost point is shown next to it.
| # | Check | Reads | Costs points when |
|---|---|---|---|
| 01 | Pool | The pool, price, age and volume | No pool and no live curve exist |
| 02 | Depth | Liquidity behind the price, pool age | Under $1,000 (−25), $3,000 (−12) or $10,000 (−5); under 10 minutes old (−10) |
| 03 | Holders | Holder count, share of the ten largest real wallets | Under 25 holders (−15); top ten over 50% (−20) or 25% (−10); creator over 10% (−8) |
| 04 | Trail | Who funded the largest wallets; the creator's record | Top wallets funded by the creator (−10 each); mostly brand-new wallets (−8); creator flagged (−25) |
| 05 | Cluster | Wallets sharing a funder; launch-block bundles and snipers | A funded group over 5% or 15%; bundles over 10% or 25%; snipers over 15% |
| 06 | Contract | Bytecode and a simulated sell | Honeypot (−60); sell tax over 5% or 10%; minting, pausing, blacklists, balance changes, upgradeable code, a live owner with powers |
| 07 | Seal | The six checks above | Never: it only adds them up |
The curve, the pools, the pool manager, the burn address and locked or LP holders are never counted as whales.
The score
- SOLID at 75 and above. CRACKED from 45 to 74. BROKEN under 45.
- A pool under 1 hour old, a token with under 50 holders, or a check that could not be read is capped at 70. It cannot be called SOLID.
- Depth sets the zone: over $250,000 is zone 1 (up to 100x), over $40,000 zone 2 (up to 25x), anything else zone 3 (up to 5x).
A SOLID verdict is not a reason to buy, and a BROKEN verdict is not proof of fraud. It is a reading, with its reasons listed.
The paper desks
Both desks, the crew's and yours, fill orders by the same rules.
| Rule | Value |
|---|---|
| Starting balance | 10,000 paper USDG |
| Price | The last trade in the deepest pool, or the Pons curve when it is deeper; Binance for majors |
| Price impact | 2 × size ÷ depth; an order moving the pool more than 8% is refused |
| Fee | 0.1% of size, in and out |
| Borrow | 0.02% an hour on the borrowed part |
| Liquidation | When 90% of the collateral is gone, fees included |
Your desk is kept in your browser. Clearing site data clears it. You may post its weekly result to the board; only the handle you choose is stored.
The crew
- Validator files each verdict and acts only on calls made in the last 30 minutes.
- Allocator puts 4% of equity on each position, shrunk so the order moves the pool at most 4%; at most 8 positions, one per token.
- Executor goes long on SOLID and short on BROKEN with a failed check, only when the pool holds $20,000 or more; 4x, 2x or 1x by zone. It never trades CRACKED.
- Sentinel marks every position each minute and closes it at liquidation, a stop (health under 0.5), a target (over 1.6) or after one day.
Tools
- Radar: every new token with 25+ holders, scanned 30 to 90 minutes after launch, then priced again an hour and a day later.
- Bond Watch: every Pons curve, read every ten minutes.
- Will it bond?: 5 curves between 20% and 80%, calls close at 12:00 UTC.
- Contract Scan, Exit Sim, Dev Record, Wallet X-ray and Reports.

FAQ
Is any real money involved?
No. Prices are real; every desk is paper.
Can a verdict be wrong?
Yes, and the misses stay on the record: the Radar's Missed tab and the crew desk's losses are public.
Why can a token not be SOLID right after launch?
Under an hour old or under 50 holders, there is too little history to hold weight, so the score is capped at 70.
