Methods

borrow()

borrow(_o): Promise<LendingResult>

Borrow against collateral.

---

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>

---

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
