Raydium Liquidity Locking decoder

carbon-raydium-liquidity-locking-decoder decodes the instructions, accounts and events of the Raydium Liquidity Locking program (LockrWmn6K5twhz3y9w1dQERbmgSaRkfnTeTKbpofwE): 4 instructions, 2 account types, 1 event. It is generated with Codama from the program's IDL; see decoders for how decoders plug into a pipeline.

More program decoders without a category: Jupiter DCA, Kamino Farms, Pump Fees, Swig. To decode several in one pipeline, see other program decoders.

The serde feature derives Serialize/Deserialize on every type, postgres adds tables and processors for Postgres, and graphql adds a schema for the GraphQL server.

Usage#

This program crawls recent Raydium Liquidity Locking transactions from the public RPC and prints every decoded CollectClmmFeesAndRewards instruction. Add the dependencies:

cargo add carbon-core@2.0.0 carbon-raydium-liquidity-locking-decoder@2.0.0 carbon-rpc-transaction-crawler-datasource@2.0.0 carbon-log-metrics@2.0.0 env_logger tokio --features tokio/full

use {
    carbon_core::{
        error::CarbonResult, instruction::InstructionProcessorInputType, pipeline::Pipeline,
        processor::Processor,
    },
    carbon_log_metrics::LogMetrics,
    carbon_raydium_liquidity_locking_decoder::{
        instructions::RaydiumLiquidityLockingInstruction, RaydiumLiquidityLockingDecoder,
        PROGRAM_ID,
    },
    carbon_rpc_transaction_crawler_datasource::{ConnectionConfig, Filters, RpcTransactionCrawler},
    std::sync::Arc,
};

#[tokio::main]
async fn main() -> CarbonResult<()> {
    env_logger::init();

    // Fetches the program's recent transactions over JSON-RPC, newest first.
    let datasource = RpcTransactionCrawler::new(
        "https://api.mainnet-beta.solana.com".to_string(),
        PROGRAM_ID,
        ConnectionConfig::default(),
        Filters::new(None, None, None),
        None,
    );

    Pipeline::builder()
        .datasource(datasource)
        .metrics(Arc::new(LogMetrics::new()))
        .instruction(RaydiumLiquidityLockingDecoder, InstructionLogger)
        .build()?
        .run()
        .await
}

struct InstructionLogger;

impl Processor<InstructionProcessorInputType<'_, RaydiumLiquidityLockingInstruction>> for InstructionLogger {
    async fn process(
        &mut self,
        input: &InstructionProcessorInputType<'_, RaydiumLiquidityLockingInstruction>,
    ) -> CarbonResult<()> {
        let signature = input.metadata.transaction_metadata.signature;
        if let RaydiumLiquidityLockingInstruction::CollectClmmFeesAndRewards { data, accounts, .. } = input.decoded_instruction {
            println!("collect_clmm_fees_and_rewards {signature}: {data:?} authority={}", accounts.authority);
        }
        Ok(())
    }
}

RUST_LOG=info cargo run

Each CollectClmmFeesAndRewards instruction prints one line with the transaction signature and the decoded CollectClmmFeesAndRewards data. The public endpoint rate-limits requests, so the first lines can take a while; use your own RPC URL for anything beyond a test. See stream with RPC for the crawler options.

Events published with Anchor's emit_cpi! arrive as the CpiEvent instruction. Match them with RaydiumLiquidityLockingInstruction::CpiEvent { data: CpiEvent::SettleCpFeeEvent(event), .. } (import instructions::CpiEvent); see Events. If CpiEvent never arrives, the program logs its events with emit! instead: decode them with decode_log_events.

Decode accounts#

The transaction crawler emits transactions only. To decode accounts, use a datasource that emits account updates. This program subscribes to the program's accounts with programSubscribe on the public WebSocket endpoint and prints every decoded LockedClmmPositionState account as it changes. Add the datasource and the Solana RPC types it takes:

cargo add carbon-rpc-program-subscribe-datasource@2.0.0 solana-client@4.2.2

use {
    carbon_core::{
        account::AccountProcessorInputType, error::CarbonResult, pipeline::Pipeline,
        processor::Processor,
    },
    carbon_log_metrics::LogMetrics,
    carbon_raydium_liquidity_locking_decoder::{
        accounts::RaydiumLiquidityLockingAccount, RaydiumLiquidityLockingDecoder, PROGRAM_ID,
    },
    carbon_rpc_program_subscribe_datasource::{Filters, RpcProgramSubscribe},
    solana_client::rpc_config::{RpcAccountInfoConfig, RpcProgramAccountsConfig, UiAccountEncoding},
    std::sync::Arc,
};

#[tokio::main]
async fn main() -> CarbonResult<()> {
    env_logger::init();

    // Streams every change to an account owned by the program (programSubscribe).
    let config = RpcProgramAccountsConfig {
        account_config: RpcAccountInfoConfig {
            encoding: Some(UiAccountEncoding::Base64),
            ..Default::default()
        },
        ..Default::default()
    };
    let datasource = RpcProgramSubscribe::new(
        "wss://api.mainnet-beta.solana.com".to_string(),
        Filters::new(PROGRAM_ID, Some(config)),
    );

    Pipeline::builder()
        .datasource(datasource)
        .metrics(Arc::new(LogMetrics::new()))
        .account(RaydiumLiquidityLockingDecoder, AccountLogger)
        .build()?
        .run()
        .await
}

struct AccountLogger;

impl Processor<AccountProcessorInputType<'_, RaydiumLiquidityLockingAccount>> for AccountLogger {
    async fn process(
        &mut self,
        input: &AccountProcessorInputType<'_, RaydiumLiquidityLockingAccount>,
    ) -> CarbonResult<()> {
        if let RaydiumLiquidityLockingAccount::LockedClmmPositionState(locked_clmm_position_state) = &input.decoded_account.data {
            println!("locked_clmm_position_state {}: {locked_clmm_position_state:?}", input.metadata.pubkey);
        }
        Ok(())
    }
}

RUST_LOG=info cargo run

Each update to a LockedClmmPositionState account prints its address and decoded fields; the program runs until you stop it. Cargo resolves solana-client to 4.2.2, the exact version the datasource pins, so both use the same RpcProgramAccountsConfig type. To load every existing account once instead of streaming changes, see load account state.

Instructions#

Variants of RaydiumLiquidityLockingInstruction. Each is RaydiumLiquidityLockingInstruction::<Variant> { program_id, data, accounts }, where data and accounts are the types listed under the variant, exported from carbon_raydium_liquidity_locking_decoder::instructions. Discriminators are the leading bytes of the instruction data, in hex.

How an instruction decodes. The decoder returns a variant only when all of these hold; otherwise the instruction is skipped and no processor is called:

1. The instruction's program ID is LockrWmn6K5twhz3y9w1dQERbmgSaRkfnTeTKbpofwE.
2. The data starts with the variant's discriminator, and the rest deserializes into its data type.
3. The instruction has at least as many accounts as the variant requires (the "Required accounts" count under each variant).

Accounts. They are matched by position, in the order listed. An account marked optional is None only when the instruction ends before it; Anchor programs pass the program ID as a placeholder for an omitted optional account, so check for Some(PROGRAM_ID) too. Accounts after the listed ones are in accounts.remaining as AccountMetas. The decoder doesn't record whether an account signed or was writable: read that from input.raw_instruction.accounts[i].is_signer and .is_writable, which follow the same order. It doesn't check signer, writable, owner or PDA constraints either; the program enforced those when the transaction executed, so a decoded instruction from a successful transaction already satisfied them.
