KaminoMarketProtocolSolana

Defined in: protocol-lending-kamino-solana/src/market.ts:67

A Kamino Lend market as a LendingProtocol: supply deposits a reserve’s token as collateral on the wallet’s obligation, withdraw takes it back, borrow / repay take and return a reserve’s liquidity against it.

Tokens are named by mint. The first deposit creates the obligation (plus user metadata and a per-user lookup table) and costs their rent, which the guard allows once; every transaction is proven before signing: only the instructions the operation takes, on the wallet’s vanilla obligation, the resolved reserve and the wallet’s own token account. The reserve is checked on chain, and ‘max’ amounts and the first-deposit allowance come from the obligation’s on-chain state.

Methods

borrow()

borrow(o): Promise<LendingResult>

Defined in: protocol-lending-kamino-solana/src/market.ts:241

Borrow against collateral.

Parameters

o

BorrowOptions

Returns

Promise<LendingResult>

Overrides

KaminoBase.borrow

decimals()

protected decimals(mint): Promise<number>

Defined in: protocol-lending-kamino-solana/src/base.ts:104

Mint decimals: the account reads the mint when it can; well-known mints need no RPC.

Parameters

mint

string

Returns

Promise<number>

Inherited from

KaminoBase.decimals

describeActivity()

describeActivity(_tx, _ctx): ActivityItem | null

Defined in: core/dist/index-QWdcwE6y.d.ts:320

Recognize one of this protocol’s own transactions in an address’s history and describe it for the wallet’s activity feed (“Supplied 100 USDC · Aave v3”). Return null when the transaction is not this protocol’s: the kit then asks the next module and finally falls back to send / receive / approve / contract call. Must be pure and synchronous: no network, no account state. The conformance suite feeds every module its recorded fixtures through this method.

Parameters

_tx

ChainTx

_ctx

DescribeActivityContext

Returns

ActivityItem | null

Inherited from

KaminoBase.describeActivity
