One install and your agent speaks Solana

We all want @x402 to win.

Our first major release from @TektonicCompany, with support from @GoogleCloudTech & @solana, brings us a step closer to institutional adoption & monitoring of x402.

We created the first high-throughput real time x402 BigQuery table for Solana and Base

who did this

[Project Hollow @ProjectHollow0]

GENUINE means less than 10% hollow holders
SUSPICIOUS means 10 to 30%
INFLATED means 30 to 60%
SYBIL FARM means over 60%

most tokens on https://t.co/YSfLz6yf9t sit somewhere between SUSPICIOUS and INFLATED. you just cant tell without scanning the wallets directly

What Hollow Does

Complete toolkit for detecting fake holders and sybil activity on Solana tokens

[Project Hollow @ProjectHollow0]

$ hollow scan TokenkegQfeZyiNwAJbNbGKPFXCWuBvf9Ss623VQ5DA

Verdict : SYBIL_FARM Grade F
Hollow : 38/50 (76.0%)
Genuine : 12
Clusters : 4
Signal : SYBIL_ALERT (HIGH)
- 76.0% of sampled holders are hollow wallets
- 4 sybil clusters (batch-created wallets)

The hardest part of building hollow was figuring out what genuine looks like

Not just what hollow looks like. any wallet with history, real SOL balance, multiple transaction types, older than a week — that is what passes. the scoring rewards organic on-chain behavior not just the absence of red flags.

that distinction matters

[Project Hollow @ProjectHollow0]

Hollow does not tell you what to buy

it tells you when the holder count is fake. that is a different and more useful thing.

CLEAN means the wallets look real
WATCH means something is off
AVOID means its inflated
SYBIL ALERT means do not touch it

[Project Hollow @ProjectHollow0]

Four things that make a wallet hollow

less than 0.002 SOL balance
fewer than 3 lifetime transactions
account created under 24 hours ago
only token buys, zero organic history

any wallet hitting 50 points across those four gets flagged. hollow does this automatically for every holder in the sample

[Project Hollow @ProjectHollow0]

a token showing 2000 holders can have 200 real ones

the rest are hollow. dust balance. one transaction. created two hours ago. never used for anything except buying that token.

hollow scores every wallet and tells you exactly how many are genuine
