Target SOL and Migration

One of the most important concepts in PrintFun's token ecosystem is the Target SOL - the amount of SOL required to trigger a token's migration from the Dynamic Bonding Curve (DBC) to Meteora's Dynamic AMM (DAMM).

Each token has its own specific Target SOL value, which is determined by the configuration parameters chosen when the token was created. This value represents the exact amount of SOL that needs to accumulate in the token's liquidity pool before migration is triggered.

This page explains how Target SOL works, how it's calculated, and why it's crucial for your token's journey.

Using the DBC SDK

The most accurate way to get the Target SOL for a specific token is to use the getPoolMigrationQuoteThreshold function from the Dynamic Bonding Curve SDK:

// Import the DBC SDK
import { DynamicBondingCurveClient } from '@meteora-ag/dynamic-bonding-curve-sdk'

// Initialize the client
const connection = new Connection('https://api.mainnet-beta.solana.com')
const client = new DynamicBondingCurveClient(connection, 'confirmed')

// Get the migration threshold for a specific pool
const poolAddress = new PublicKey('your_token_pool_address')
const threshold = await client.state.getPoolMigrationQuoteThreshold(poolAddress)

// Convert from lamports to SOL
const targetSol = threshold.toNumber() / 1e9
console.log(`Target SOL: ${targetSol} SOL`)

This function returns the exact amount of SOL (in lamports) required for the token to migrate. Divide by 10^9 to convert to SOL.

Finding a Token's Target SOL on PrintFun

You can easily find a token's Target SOL value on its detail page on PrintFun. Navigate to the token's page and look for the "Target SOL" value in the Token Stats section. This shows the exact amount of SOL needed to trigger migration for that specific token.

Checking Migration Progress

You can also check how close a token is to reaching its Target SOL using the getPoolCurveProgress function:

// Get the progress percentage (0-1)
const progress = await client.state.getPoolCurveProgress(poolAddress)
console.log(`Migration Progress: ${progress * 100}%`)

This returns a value between 0 and 1, representing the percentage of Target SOL that has been accumulated so far.

Fee Tiers After Migration

When configuring your token, you can choose from several fee tiers that will apply after migration:

Migration Options and Fee Distribution

PrintFun offers two migration options that affect how holders receive rewards after migration. Whether fees are paid in SOL or in the token depends on which DAMM pool they migrate to:
