Constructors

Constructor

new ApproveToken(): ApproveToken

Returns

ApproveToken

Inherited from

SolanaOperation< ApproveTokenParams, UnsignedSolanaTx, ParsedApproveTokenParams >.constructor

Properties

name

readonly name: "approveToken" = 'approveToken'

Defined in: cct/solana/token/operations/approve-token.ts:68

camelCase id; matches the token-manager facade method and error context.

Overrides

SolanaOperation.name

---

splitMode

protected readonly splitMode: SolanaSplitMode = 'atomic'

Defined in: cct/solana/operation.ts:36

Multi-transaction safety policy; resource splitting requires an operation-specific audit.

Inherited from

SolanaOperation.splitMode

Methods

buildUnsigned()

protected buildUnsigned(chain: SolanaChain, opts: ParsedApproveTokenParams): Promise<UnsignedSolanaTx>

Defined in: cct/solana/token/operations/approve-token.ts:97

Builds an SPL Token Approve instruction.

Parameters

Parameter	Type
chain	SolanaChain
opts	ParsedApproveTokenParams

Returns

Promise<UnsignedSolanaTx>

Overrides

SolanaOperation.buildUnsigned

---

execute()

execute(chain: SolanaChain, params: ExecuteApproveTokenParams): Promise<TransactionResult>

Defined in: cct/solana/token/operations/approve-token.ts:126

Generate, sign, simulate, send, and confirm with the token account owner wallet.

Parameters

Parameter	Type
chain	SolanaChain
params	ExecuteApproveTokenParams

Returns

Promise<TransactionResult>

Overrides

SolanaOperation.execute

---

generate()

generate(chain: SolanaChain, params: SolanaGenerateParams<ApproveTokenParams>): Promise<UnsignedSolanaTx>

Defined in: cct/solana/operation.ts:42

Run prepare and buildUnsigned; no signing.

Parameters

Parameter	Type
chain	SolanaChain
params	SolanaGenerateParams<ApproveTokenParams>

Returns

Promise<UnsignedSolanaTx>

Inherited from

SolanaOperation.generate

---

parse()

protected parse(params: GenerateApproveTokenParams): ParsedApproveTokenParams

Defined in: cct/solana/token/operations/approve-token.ts:71

Parses public keys, allowance, and optional SPL Token multisig signers.

Parameters

Parameter	Type
params	GenerateApproveTokenParams

Returns

ParsedApproveTokenParams

Overrides

SolanaOperation.parse

---

prepare()

protected prepare(params: SolanaGenerateParams): ParsedApproveTokenParams

Defined in: cct/operation.ts:48

validate then parse — the single pre-RPC step, before any chain access.

Parameters

Parameter	Type
params	SolanaGenerateParams

Returns

ParsedApproveTokenParams

Inherited from

SolanaOperation.prepare

---

prepareWalletExecution()

protected prepareWalletExecution(params: SolanaExecuteParams<ApproveTokenParams>): { computeUnits: number | undefined; parsed: ParsedApproveTokenParams; payer: PublicKey; wallet: Wallet; }

Defined in: cct/solana/operation.ts:47

Validates the wallet and prepares signed execution parameters with it as payer.

Parameters

Parameter	Type
params	SolanaExecuteParams<ApproveTokenParams>

Returns

{ computeUnits: number | undefined; parsed: ParsedApproveTokenParams; payer: PublicKey; wallet: Wallet; }

computeUnits

computeUnits: number | undefined

parsed

parsed: ParsedApproveTokenParams

payer

payer: PublicKey

wallet

wallet: Wallet

Inherited from

SolanaOperation.prepareWalletExecution

---

validate()

protected validate(_params: SolanaGenerateParams): void

Defined in: cct/operation.ts:36

Reject invalid params before any chain RPC. No-op by default: an op that normalizes as it checks does that work in parse instead, and needs no empty stub here.

Parameters

Parameter	Type
_params	SolanaGenerateParams

Returns

void

Inherited from

SolanaOperation.validate
