DAMM v2 Go Integration Reference

The public damm-v2-go repository provides Go examples for reading DAMM v2 state with solana-go. Treat it as example code for account reads, deserialization, and selected low-level instructions rather than a full transaction SDK.

Setup

git clone https://github.com/MeteoraAg/damm-v2-go.git
cd damm-v2-go
go mod tidy

Before running examples, set the RPC endpoint and addresses in the example file you are using. Some examples also require uncommenting the local main() function.

go run examples/get_pool.go

Available Examples

Example	Use
`get_pool.go`	Fetch and deserialize a pool account
`get_position.go`	Fetch and deserialize a position account
`get_positions_by_user.go`	Resolve position NFTs and fetch positions for a wallet
`get_user_position_by_pool.go`	Filter a user’s positions by pool
`get_all_position_nft_account_by_owner.go`	Read position NFT token accounts by owner
`get_unclaim_reward.go`	Calculate unclaimed reward information
`claim_position_fee.go`	Example transaction flow for claiming position fees

The Go constants include the public DAMM v2 program ID:

const DammV2ProgramID = "cpamdpZCGKUy5JxQXB4dcpGPiikHawvSWAd6mEn1sGG"

Helpers And Validation

Helper	Use
`DerivePoolAuthorityPDA()`	Derives the `pool_authority` PDA
`DeriveEventAuthorityPDA()`	Derives the `__event_authority` PDA used by event CPI instructions
`DerivePositionPDA(positionNft)`	Derives the `position` PDA from the position NFT mint
`GetPool(ctx, pool, rpcClient)`	Fetches and deserializes a pool after checking the Anchor discriminator
`GetPosition(ctx, position, rpcClient)`	Fetches and deserializes a position after checking the Anchor discriminator
`GetPositionsByUser(ctx, rpcClient, user)`	Resolves position NFTs, derives position PDAs, fetches positions, and sorts by total liquidity
`ClaimPositionFee(...)`	Builds a low-level claim-fee instruction including event CPI accounts

Integration Notes

Topic	Guidance
Account validation	Example readers check Anchor discriminators before deserializing pool and position data.
Position ownership	User-position lookup starts from Token 2022 position NFT accounts owned by the wallet.
Transaction builders	Prefer the TypeScript SDK unless you are comfortable maintaining low-level Go instruction builders from the IDL.
Module path	The local `go.mod` currently uses a different module path than the public repository name. Check upstream before importing it as a library.
State freshness	Fetch pool accounts directly for transaction-critical reads; use the API for discovery and chart data.
Event CPI accounts	Low-level instructions that emit events need `event_authority` and the program account in the expected account order.

For custom Go clients, generate from the public cp_amm IDL and cross-check account layouts against Accounts.
