Proof · How we stay honest

Every trade leaves a trace.

Every position Kabal opens or closes — paper or live — posts an SPL Memo to Solana mainnet. A cryptographic receipt that's public, timestamped, and impossible to rewrite. This is how an autonomous squad stays trust-minimized.

~200 bytes per trade. Memo-only transactions cost a few lamports. Paper trades are flagged mode: paper — the squad posts the decision without moving funds, so the audit trail is continuous across the V.0 → V.1 cutover.

Why memos, not a centralized log

✕ Trust-us logs

Most "AI trading bot" projects log trades to their own server. You see a dashboard. You don't see the database. Numbers can be rewritten overnight. Losses can disappear.

✓ Memo proofs

Solana's ledger is append-only. Once a Kabal memo is confirmed, it's there forever. We can't rewrite a trade that went bad. You can verify any claim independently of our dashboard.

How it works in five steps

Trader decides

Reaver or Ash or Myth or Ravage signals an entry / exit.

Sentinel clears

Three-tier risk check. Veto or pass. Recorded either way.

Transaction builds

Trade instruction (or paper stub) + SPL Memo bundled.

Signed & sent

Wallet signs. Sent to Solana. Confirmed ~400ms.

Librarian indexes

Memo hash + sig stored. Cross-referenced with outcome on exit.

The rule is simple: if there is no memo, there was no trade. The squad cannot execute without posting its reasoning on-chain first. It's the cheapest integrity mechanism we could design.

Questions people ask

Doesn't posting every trade leak strategy?

Memos post after the trade fires, not before. By the time you read one, the position is already open. Strategy surface (PUMP_PHASE, BREAKOUT, NARRATIVE, TRENDING) is public anyway — the edge is in execution timing and the ghost filters, which are parameter-hidden. We disclose the shape, not the weights.

What stops Kabal from posting a fake memo after the fact?

Blockchain timestamps. Every memo sits in a confirmed block with a network-level time. We can't backdate one. If a trade "appeared" at 14:32:07 UTC, the rest of Solana validators already saw it at that block — we can't rewrite the transaction log retroactively.

How do I verify one?

Copy the transaction signature from any trade card, paste into solscan.io or solana.fm, and expand the memo instruction. The JSON payload is exactly what our dashboard displays. If they diverge — we were lying.

Is this expensive at V.0 volume?

No. ~0.000005 SOL per memo transaction. 294 paper trades over 7 sessions cost less than 0.002 SOL in fees total. At live volume, the memo cost is a rounding error on the trade cost itself.

Why SPL Memo and not an account program?

Memos are universally indexable, don't require deploying a program, and are standard across Solana tooling. A custom program would let us enforce schemas, but locks users into our verification path. We picked the maximally-portable option on purpose.

Ghost filters · v1

Five pre-trade rug checks. Every signal passes through all five before Sentinel clears. Any hard-reject kills the trade before it builds.

Filter 1

Bundle detection

Same-block buyers ≥ 3 wallets at deploy. Hard reject at ≥ 3.

● active · threshold locked

Filter 2

Deployer age

Wallet age < 24h ? Warn. < 1h ? Hard reject.

● active · Helius lookup

Filter 3

Insider concentration

Top-10 non-LP wallet share. > 30% warn · > 50% hard reject.

● active · supply snapshot

Filter 4

LP lock

Liquidity must be burned or in a lock contract. Unlocked = veto.

● active · raydium/meteora

Filter 5

Sniper cluster

Known sniper cohort in first 3 blocks. Size > 10% supply = hard reject.

● active · cptn archive
