svm venue: perps-jlp

Solana venue integration perps-jlp, exported from @eco-incorp/sauce/svm. Generated from the type declarations of @eco-incorp/sauce.

`bakedDecimalScale`

Function · @eco-incorp/sauce/svm Baked scale for floor(c1 * c2 * 10^(e1+e2-te)) - the shared shape of every checkedDecimalMul(c1, e1, c2, e2, te) call this venue’s math uses (both the exchange-rate conversion and every USD conversion). Because decimals/exponents are all baked (governance/feed constants), the SIGN of targetPower is known off-chain, so the fragment never needs a runtime branch: exactly one of scaleUp/scaleDown is ever != 1, so floor(c1 * c2 * scaleUp / scaleDown) reproduces the reference’s two-way branch with ONE unconditional expression.

export declare function bakedDecimalScale(e1: number, e2: number, targetExponent: number): {
    scaleUp: bigint;
    scaleDown: bigint;
};

`custodyPda`

Function · @eco-incorp/sauce/svm findProgramAddress(["custody", pool, mint], PERPS_JLP_PROGRAM_ID) - verified against real SOL custody.

export declare function custodyPda(pool: Address, mint: Address): Promise<Address>;

`transferAuthorityPda`

Function · @eco-incorp/sauce/svm findProgramAddress(["transfer_authority"], PERPS_JLP_PROGRAM_ID) - a program-wide constant.

export declare function transferAuthorityPda(): Promise<Address>;

`perpetualsPda`

Function · @eco-incorp/sauce/svm findProgramAddress(["perpetuals"], PERPS_JLP_PROGRAM_ID) - a program-wide constant.

export declare function perpetualsPda(): Promise<Address>;

`eventAuthorityPda`

Function · @eco-incorp/sauce/svm findProgramAddress(["__event_authority"], PERPS_JLP_PROGRAM_ID) - matches the published constant.

export declare function eventAuthorityPda(): Promise<Address>;

`fetchPerpsJlpConfig`

Function · @eco-incorp/sauce/svm custodyIn is the account to decode DIRECTLY (its mint field IS mintIn - self-discovered, never taken on faith from a caller) - the address-source derives it deterministically from pair.inMint (see ladder discovery wiring), so this function never needs the input mint as a separate argument. mintOut is the ONE piece of information genuinely external: a basket has no single account embedding both sides, so SOMETHING must name which of the OTHER custodies this trade targets.

export declare function fetchPerpsJlpConfig(owned: OwnedAccountLoader, custodyIn: Address, mintOut: Address, now?: bigint): Promise<PerpsJlpPoolConfig>;

`PERPS_JLP_PROGRAM_ID`

Variable · @eco-incorp/sauce/svm

PERPS_JLP_PROGRAM_ID: Address<"PERPHjGBqRHArX4DySjwM6UJHiR3sWAatqfdBS2qQJu">

`JLP_POOL_ADDRESS`

Variable · @eco-incorp/sauce/svm The single production JLP pool (name “Pool”, 6 custodies as of 2026-07-31).

JLP_POOL_ADDRESS: Address<"5BUwFW4nRbftYTDMbgxykoFWqWHPzahFSNAaaaJtVKsq">

`SWAP2_DISCRIMINATOR`

Variable · @eco-incorp/sauce/svm sha256(‘global:swap2’)[0..8].

SWAP2_DISCRIMINATOR: number[]

`CUSTODY_ACCOUNT_SIZE`

Variable · @eco-incorp/sauce/svm The full occupied Custody struct length (confirmed all-zero padding past this on 6 real mainnet custodies).

CUSTODY_ACCOUNT_SIZE = 1117

`DOVES_PRICE_OFFSET`

Variable · @eco-incorp/sauce/svm

DOVES_PRICE_OFFSET = 73

`DOVES_EXPO_OFFSET`

Variable · @eco-incorp/sauce/svm

DOVES_EXPO_OFFSET = 81

`DOVES_TIMESTAMP_OFFSET`

Variable · @eco-incorp/sauce/svm

DOVES_TIMESTAMP_OFFSET = 82

`DOVES_FEED_SIZE`

Variable · @eco-incorp/sauce/svm

DOVES_FEED_SIZE = 91

`DOVES_MAX_AGE_SEC`

Variable · @eco-incorp/sauce/svm A “the feed is dead, not just latent” sanity ceiling (seconds) - the real on-chain custody enforces its OWN much tighter oracle.maxPriceAgeSec (observed 5s on the real mainnet SOL/USDC custodies 2026-07-31) at swap2 execution time; that live, on-chain check is the authoritative freshness backstop and reverts the whole cook for this slot if violated, exactly like every other venue’s runtime-failure self-drop. Trying to replicate a 5s bound OFF-CHAIN at prepare time would self-drop this venue almost unconditionally (any nonzero prepare-to-cook latency exceeds it) - a “NO PREMATURE GATING” violation, not a safety measure. This constant only catches a feed that has stopped updating entirely (an abandoned/broken Doves keeper), not ordinary staleness.

DOVES_MAX_AGE_SEC = 3600n

`PerpsJlpPoolConfig`

    fetchPoolConfig: typeof fetchPerpsJlpConfig;
}

`perpsJlpConfig`

Function · @eco-incorp/sauce/svm

declare function perpsJlpConfig(cfg: PoolConfig): PerpsJlpPoolConfig;

`ORACLE_PRICE_SCALE`
