Create DBC Config Key

This script creates a DBC Config Key using the buildCurveWithMarketCap function (this function helps to abstract the math complexity of creating a DBC Config Key).

You can also use the buildCurve, buildCurveWithTwoSegments, and buildCurveWithLiquidityWeights functions to create a DBC Config Key.

buildCurve is a function that primarily uses migrationQuoteThreshold and percentageSupplyOnMigration to build the curve config. This function is useful when you want to create a curve config with a specific migration quote threshold and percentage of supply on migration.
buildCurveWithMarketCap is a function that primarily uses initialMarketCap and migrationMarketCap to build the curve config. This function is useful when you want to create a curve config that has a specific starting token price and an ending migration token price.
buildCurveWithTwoSegments is a function that uses initialMarketCap, migrationMarketCap and percentageSupplyOnMigration to build the curve config. This function is useful when you want to create a 2 constant product curve structure with a specific initial market cap, migration market cap and percentage of supply on migration.
buildCurveWithLiquidityWeights is a function that uses initialMarketCap, migrationMarketCap and liquidityWeights to build the curve config. This function is useful when you want to create a curve config with a unique price action (flat, exponential, etc.) with a specific initial market cap, migration market cap and liquidity weights.

Migrate to DAMM v2

This script migrates a DBC Token Pool to DAMM V2.

The migration process follows these steps:

Create Migration Metadata (skip if metadata exists)
Create Locker (checks if baseMint token has Locked Vesting, and if lockEscrow has been created)
Migrate to DAMM V2 (if isMigrated = 0)
