Overview
Holdr is an AI agent that deploys meme coins on Solana directly from X comments. Tag @holdr_bot in any post and the agent parses your intent, generates token metadata, and deploys the contract on-chain — all within seconds. Tokens are powered by the Printr bonding curve.
Every token deployed through Holdr inherits the full Printr infrastructure: a bonding curve for price discovery, automatic graduation to a DEX at $50K market cap, GoPlus liquidity locking, and the Holdr reward mechanism that pays holders from creator fees.
Holdr runs on top of Printr — the bonding curve launchpad. All on-chain mechanics, fee routing, and graduation are handled by the Printr protocol.
How It Works
From a single X comment to a live tradeable token in four automated steps.
The agent polls for new @holdr_bot mentions every 30 seconds. Your token is typically live within 1–2 minutes of posting.
Quick Start
Launch a token in one comment. Use the format below.
Command tips
- Name — keep it under 32 characters. Spaces are allowed.
- Symbol — 2–8 characters, uppercase. No spaces or special characters.
- Description — a short sentence describing the coin's vibe. The AI uses this to generate metadata and artwork.
- Image — attach an image to your post and the agent will use it as the token logo. If none is provided, an AI-generated image is created automatically.
- One launch per comment — the agent processes the first valid launch command it finds per mention.
Quote-tweeting a viral post with @holdr_bot launch PepeRocket PRKT the fastest pepe in the galaxy will deploy PRKT and reply with the trade link directly under your quote-tweet.
AI Agent
The Holdr agent is an autonomous process running continuously on the Printr backend. It monitors X for mentions and takes action without any human in the loop.
What the agent does
- Polls @holdr_bot mentions on X every 30 seconds
- Parses the comment intent using a large language model
- Validates the token name, symbol, and description
- Generates AI artwork if no image is attached to the post
- Deploys the token contract to Solana via Printr
- Replies to the original X comment with the live trade link
- Records the deployment to the Holdr dashboard
What the agent does not do
- The agent does not buy or sell tokens on your behalf
- The agent does not hold private keys for user wallets
- The agent will not deploy if the ticker is under an active anti-vamp cooldown
- The agent will not process private or protected X accounts
The AI uses context from the post being replied to when generating metadata — so if you tag @holdr_bot in a reply to a viral meme, the token's identity will reflect that context.
Token Deployment
All tokens deployed by Holdr use the following default configuration on Printr.
| Parameter | Default Value | Notes |
|---|---|---|
| Starting Market Cap | $3,000 | Initial virtual liquidity on the bonding curve |
| Graduation Market Cap | $50,000 | Triggers automatic DEX migration |
| Total Supply | 1,000,000,000 | 1 billion tokens, fixed at deployment |
| Liquidity Allocation | 79% | Reserved for bonding curve and DEX pool |
| Chain | Solana | More chains coming soon |
| Initial Buy | 0.01 SOL | Seed purchase executed at deployment |
| Quote Token | SOL | All trades denominated in SOL |
Token contracts are deployed and verified on-chain via Printr. Metadata (name, symbol, description, image) is uploaded to IPFS and pinned before deployment completes.
Fee Model
Holdr uses a creator fee distribution model. Fees are collected on every trade and distributed back to token holders on a 24-hour cycle.
The creator fee is separate from the Printr platform fee. The X account that deployed the token accumulates this fee from trading volume, which is then distributed to holders as a reward — incentivising community building over quick sells.
Trading fees → Creator fee pool → 24h snapshot of holder balances → Proportional distribution weighted by hold duration multiplier → Holder wallets.
Holder Rewards
Holdr rewards long-term holders from trading fees. The longer you hold, the larger your share of the distribution pool.
Distribution mechanics
- Snapshots are taken every 24 hours
- A minimum hold period of 24 hours is required to qualify for rewards
- Your reward share is proportional to your token balance × hold duration multiplier
- Rewards are sent directly to the wallet that holds the tokens — no claiming required
- Unclaimed rewards from missed cycles do not roll over to the next cycle
Reward formula
Example — 3 holders, total pool = 100 SOL
| Holder | Balance | Hold Duration | Multiplier | Weighted | Reward |
|---|---|---|---|---|---|
| Holder A | 500,000 | 7 days | 1.30× | 650,000 | 63.41 SOL |
| Holder B | 200,000 | 1 day | 1.00× | 200,000 | 19.51 SOL |
| Holder C | 100,000 | 30 days | 1.75× | 175,000 | 17.07 SOL |
Bonding Curve
Every Holdr token uses the Printr Memecoin profile bonding curve for price discovery before graduating to a DEX.
How it works
A bonding curve is a smart contract that sets token price algorithmically based on supply. As more tokens are bought, the price increases. As tokens are sold, the price decreases. This removes the need for a traditional order book at launch.
- All buys and sells execute against the curve contract — no counterparty needed
- Price is fully deterministic and visible on-chain at all times
- 79% of the token supply is allocated to the bonding curve pool
- Virtual liquidity of $3,000 is seeded at launch to set the initial price floor
Memecoin profile default
Holdr uses the Memecoin bonding curve profile on Printr. This profile is optimised for high-volatility, community-driven tokens: a steeper early curve rewards early buyers with larger price appreciation, while the $50K graduation target keeps momentum achievable without requiring enormous volume.
The bonding curve contract holds all liquidity. The deployer cannot withdraw curve funds — liquidity only moves when tokens are traded or when the graduation threshold is reached.
Graduation
When a token's market cap reaches $50,000 on the bonding curve, it automatically graduates to a decentralised exchange.
What happens at $50K
- The bonding curve contract closes to new buys and sells
- All accumulated SOL from the curve is paired with the remaining token supply
- A liquidity pool is created on a Solana DEX (Raydium or equivalent)
- LP tokens are locked via GoPlus — the creator cannot withdraw liquidity post-graduation
- Post-graduation fee (0.20%) begins routing from DEX swap fees to the creator reward pool
- The token is now freely tradeable on the open market with full DEX depth
GoPlus enforces a time-locked LP position at graduation. This ensures the liquidity pool cannot be drained immediately after launch, protecting holders who bought on the bonding curve.
Anti-Vamp Protection
Holdr includes a 48-hour cooldown mechanism to prevent ticker and image squatting.
How it works
When a token is successfully deployed, its ticker symbol and uploaded image (if any) are locked for 48 hours. Any attempt to deploy a new token using the same ticker or the same image within that window will be blocked by the agent.
- Ticker cooldown — if
MCATwas deployed 12 hours ago, a newMCATlaunch will be rejected - Image cooldown — perceptual hash matching prevents the same artwork being reused across different tokens
- After 48 hours the ticker and image become available again on a first-come basis
- Cooldowns apply globally across all users, not just the original deployer
If someone launches PEPE at 09:00 UTC on Monday, no one can deploy another PEPE until 09:00 UTC on Wednesday. @holdr_bot will reply with a cooldown notice and the time remaining if you attempt it.
Supported Chains
Holdr currently deploys to Solana. Additional chains are on the roadmap.
Multi-chain support will allow the same @holdr_bot command syntax to target a specific chain using a flag in the comment (e.g. --base or --eth). Without a flag, the agent defaults to Solana.
Fee Breakdown
Complete fee tables for bonding curve trading and post-graduation DEX trades.
Bonding curve fees
| Fee Type | Rate | Recipient | Applies To |
|---|---|---|---|
| Creator Fee | 0.40% | Holder reward pool | Every buy and sell |
| Printr Platform Fee | 1.00% | Printr protocol | Every buy and sell |
| Total Curve Fee | 1.40% | — | Per trade |
Post-graduation DEX fees
| Fee Type | Rate | Recipient | Applies To |
|---|---|---|---|
| Creator Fee | 0.20% | Holder reward pool | Every DEX swap |
| Printr Platform Fee | 0.80% | Printr protocol | Every DEX swap |
| DEX LP Fee | 0.25% | LP providers | Every DEX swap |
| Total Post-Grad Fee | 1.25% | — | Per swap |
All fees above are indicative and subject to change by the Printr protocol. The creator fee split (0.40% bonding curve / 0.20% post-graduation) is fixed at deployment and cannot be altered per token.
Reward Calculation
How your individual reward is calculated each 24-hour distribution cycle.
Formula
Worked example
The biggest lever on your reward is the hold duration multiplier. Holding for 30 days gives you a 1.75× weight vs 1.0× for a fresh 24h hold — on the same balance, that is 75% more SOL per cycle.
Hold Duration Multipliers
The longer you hold, the greater your weight in the reward distribution snapshot.
| Hold Duration | Multiplier | Reward Weight vs 24h Baseline |
|---|---|---|
| 24 hours | 1.00× | Baseline |
| 3 days | 1.15× | +15% |
| 7 days | 1.30× | +30% |
| 14 days | 1.50× | +50% |
| 30 days | 1.75× | +75% |
| 60 days+ | 2.50× | +150% |
Hold duration is measured from the time tokens entered your wallet. Selling any portion of your position resets the duration clock for the sold amount only. The remaining balance retains its original entry timestamp.
A 60-day holder with 100,000 tokens has the same reward weight as a 24h holder with 250,000 tokens. Long-term commitment is rewarded more than raw balance size.
