Readme

Meteora Dynamic Bonding Curve SDK

A Typescript SDK for interacting with the Dynamic Bonding Curve on Meteora.

Overview

This SDK provides a set of tools and methods to interact with the Meteora Dynamic Bonding Curve. It enables developers to easily create and manage dynamic bonding curves, with support for custom configurations and fee structures.

Installation

npm install @meteora-ag/dynamic-bonding-curve-sdk
# or
pnpm install @meteora-ag/dynamic-bonding-curve-sdk
# or
yarn add @meteora-ag/dynamic-bonding-curve-sdk

Initialization

import { Connection } from '@solana/web3.js'
import { DynamicBondingCurveClient } from '@meteora-ag/dynamic-bonding-curve-sdk'

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

Usage

Refer to the docs for how to use the functions.

Flow

The generic flow of how Dynamic Bonding Curve works is as follows:

  1. The partner creates a config key for the pool.
  2. The creator creates a pool.
  3. The pool is tradeable on the Dynamic Bonding Curve.
  4. Meteora's migrator service migrates the pool to either DAMM V1 or DAMM V2 based on the config key once the migration quote threshold is met.
  5. The graduated pool is tradeable on either DAMM V1 or DAMM V2.

Flow of migration

DAMM V1

  1. createDammV1MigrationMetadata
  2. createLocker (if the token has locked vesting)
  3. migrateToDammV1
  4. lockDammV1LpToken (if creatorLockedLpPercentage or partnerLockedLpPercentage is >0)
  5. claimDammV1LpToken (if creatorLpPercentage or partnerLpPercentage is >0)

DAMM V2

  1. createLocker (if the token has locked vesting)
  2. migrateToDammV2

Test

bun install
bun test

Manual Migrator

We have created a Manual Migrator UI that allows you to manually migrate a pool to either DAMM V1 or DAMM V2. Compatible with both Mainnet and Devnet pools.
