Reading Buyer Quality
The first 20–50 buyers determine the holder base that will either sustain or collapse the token. High-quality early buyers look like:
- Wallets aged more than 30 days
- Trading history across multiple tokens (diversified, not single-token concentration)
- Mix of trade sizes (not uniformly $100 or uniformly $1,000 — human variation)
- Transaction failure rate below 15%
- Entry timing spread across 1–5 minutes (not all in the same block)
Low-quality early buyers look like:
- Wallets created in the last 72 hours
- Single-token or two-token trading history
- Identical trade sizes across multiple wallets
- Sub-second entry timing on multiple wallets (same-block execution)
- High transaction failure rates
The buyer quality score aggregates these signals into a single metric per token. A token with an average buyer quality score of 0.3 (low) in its first 20 buyers is dominated by bots and coordinated wallets. A token scoring 0.7+ across its first 20 buyers has a human-dominated holder base with a meaningfully better survival profile.
Holder Concentration and Bundling
Two additional signals to check before entering:
Top 10 holder concentration: On high-risk pump.fun tokens, the top 10 holders typically control 30–50% of supply, and the first 10–20 buyers hold 17–19 percentage points more supply than holders in lower-risk tokens. High concentration = a small group controls whether the price moves up or down. When they exit, the price collapses.
Bundling: Bundled launches involve a single operator controlling multiple wallets that buy simultaneously on token creation, often within the same Jito bundle. This gives the operator a large, cheap position before any retail buyer can enter. Bundle checker tools surface these within seconds of launch. A token that was bundled at launch almost never survives long — the bundler's entire profit model depends on dumping into incoming retail.
The 60-Second Checklist
Before buying any new pump.fun token, these five checks take under 60 seconds:
-
Deployer history — search the deployer wallet on Solscan. How many prior token launches? What was their fate?
-
Bundle check — run the token through a bundle checker. Was the launch bundled? What percentage of supply did the bundler take?
-
First buyer list — look at the first 10–20 buyers on the token's DexScreener page. Are the wallets aged and diverse, or fresh and similar-sized?
-
Top holder concentration — what do the top 10 holders control? Above 40% is a red flag.
-
Bonding curve shape — is the chart showing organic accumulation (multiple price discovery cycles, consistent buy pressure) or a single spike (manufactured pump)?
If 3 of these 5 checks fail, the token is in the failure category. If all 5 pass, you have a token with the on-chain fingerprint of a survivor — not a guarantee, but a meaningfully better base rate. We turn this exact workflow into a repeatable scoring routine in how to score a new pump.fun token in 60 seconds.
Where Buyer Quality Score Comes From
Manual checking works for individual tokens. For traders watching dozens of new launches simultaneously, manual checks do not scale.
The MadeOnSol token API provides a pre-calculated buyer_quality_score for any token mint address — a 0–1 score based on automated analysis of the first 50 buyers across the dimensions above: wallet age, trading history, entry timing patterns, transaction failure rate, and single-token concentration. The score is available via REST and updates in real time as new buyers enter.
The /v1/tokens/{mint}/buyer-quality endpoint returns the score plus the underlying signals, so you can build your own filtering logic on top.
Combined with the deployer score (also available in the API) and our KOL first-touch data for the same token, you get a complete picture of whether a new pump.fun launch has the profile of a survivor or a rug before you commit capital.
Both endpoints are available on the free tier (no card required). API docs and pricing →
FAQ
What percentage of pump.fun tokens actually make it to Raydium?
Roughly 1–2% of pump.fun tokens graduate to Raydium (reaching the ~$90K market cap threshold). The majority die on the bonding curve within the first hour.
Is bundling illegal?
No. Bundling — coordinating multiple wallets to buy simultaneously via Jito — is a transaction strategy, not a legal violation. It is widely considered manipulative by the community, and bundled launches have much higher failure rates for retail buyers, but it is not prohibited.
What is a good buyer quality score?
Scores above 0.6 indicate a majority of early buyers show human trading patterns. Scores below 0.3 indicate bot or coordinated wallet dominance. Most pump.fun launches score between 0.2 and 0.4 on launch.
Does deployer history matter if the token looks good otherwise?
Yes, significantly. A deployer with 30+ prior dumps has demonstrated a consistent pattern regardless of how the current token looks on surface metrics. Deployer history is one of the highest-weight signals.
How do I check if a token was bundled?
Several free bundle checkers exist for Solana — search "Solana bundle checker" for current options. Our token API also includes a bundled supply flag. Bundle detection is immediate after launch.
Can KOL wallets entering a token override bad deployer signals?
Sometimes, but not reliably. If 5+ tracked KOL wallets with strong track records enter a token with a serial-dumper deployer, the KOLs may be acting on inside information that the deployer is genuine this time — or the KOLs themselves are coordinating the pump. Either way, the risk profile is elevated and position sizing should reflect that.
Is there a faster way to screen for these signals?
Yes — see our 60-second pump.fun scoring checklist for a condensed version of these checks, and finding pump.fun tokens before KOLs tweet for the entry-timing side of this.
