​
Token Creation

Anyone can create a token on JustPump with zero upfront cost. There’s no need to provide liquidity or pay launch fees—your token starts trading immediately on a bonding curve.

​
Supply Allocation

When you create a token, 100% of the total supply goes into the liquidity pool and is available for trading through the bonding curve mechanism.
All tokens are held in the bonding curve smart contract initially. As the token graduates, liquidity is migrated to the permanent AMM pool with locked liquidity.

​
Immediate Trading

Once created, your token:
  • Starts trading immediately on the bonding curve
  • Has metadata stored via Solana token programs
  • Is fully on-chain and transparent
  • Requires no additional setup or configuration

​
Bonding Curve Trading

Tokens trade on a linear bonding curve during the initial phase. This provides fair and predictable price discovery.

​
How Bonding Curves Work

The bonding curve uses a simple mathematical formula:
  • Every buy increases the price based on how many tokens have been sold
  • Every sell decreases the price proportionally
  • Price is deterministic and transparent—no hidden mechanics
  • All trades execute instantly and on-chain
The price at any point is calculated as:
Price = base_price + (slope × tokens_sold)
For buying t tokens, the cost includes the area under the curve, accounting for the increasing price as more tokens are sold.

​
Anti-Rug Protection

JustPump includes built-in protection against rug pulls and market manipulation.
10% Maximum Sell Limit: You can only sell up to 10% of the circulating supply in a single transaction. This prevents large holders from dumping and crashing the price instantly.
This mechanism gives the community time to detect and respond to suspicious activity. Large holders must split sells across multiple transactions, making their actions visible.

​
Graduation Process

When a token reaches certain conditions, it graduates from the bonding curve to a permanent liquidity pool on JustSwap.

​
Graduation Threshold

A token graduates when 85 SOL in collected quotes is reached through bonding curve trading.

​
What Happens During Graduation

1

Status Update

The token status changes from OnCurve to ReadyToMigrate, indicating graduation is imminent.
2

Liquidity Transfer

The smart contract automatically transfers the remaining liquidity to create the permanent AMM pool:
  • Remaining token supply to the AMM base vault
  • 85 SOL collected from bonding curve trades to the AMM quote vault
3

Pool Creation

A canonical liquidity pool is created on JustSwap using a Cross-Program Invocation (CPI). Only the launchpad program can create these canonical pools.
4

LP Token Minting

Liquidity provider (LP) tokens are minted and locked permanently to the pool PDA (Program Derived Address). These cannot be withdrawn—ensuring permanent liquidity.
5

Mint Authority Revocation

The mint authority for the token is revoked, fixing the supply forever. No new tokens can be created.
6

Trading Begins

The token is now available for trading on JustSwap with the constant product AMM formula (x × y = k). All future trades happen on the AMM, not the bonding curve.

​
After Graduation

Once graduated:
  • Token has permanent locked liquidity (cannot be removed)
  • Supply is fixed (no more minting possible)
  • Trades execute on JustSwap AMM with market-driven pricing
  • Fees are typically lower than bonding curve fees
  • Token is eligible for external integrations and listing on other platforms
Graduation represents a major milestone for a token—it transitions from a speculative launch phase to a more mature, liquid trading environment with permanent guarantees.

​
Summary

Launch

Create tokens instantly with zero cost. 100% of supply goes into the liquidity pool for immediate trading.

Trade

Fair bonding curve pricing with 10% anti-rug protection. All trades on-chain and transparent.

Graduate

At 85 SOL, token migrates to permanent liquidity pool with fixed supply and locked liquidity.
