Class: ApplyChainUpdates

Defined in: cct/solana/token-pool/operations/apply-chain-updates.ts:212

Applies the EVM applyChainUpdates equivalent as Solana instructions.

Remarks

Chain selectors to add and remove must not contain duplicates. This preserves EVM ordering: all removals run first, then each added chain is initialized, configured with remote pools, and assigned both rate-limit configs. EVM-style replacement is supported by listing a selector in both remoteChainSelectorsToRemove and chainsToAdd; adding an existing selector without removing it fails. Updates are packed into one or more transactions, keeping each chain's initialization, configuration, and rate-limit instructions together. Batches are submitted sequentially; a later failure leaves earlier batches committed.

Constructors

Constructor

new ApplyChainUpdates(): ApplyChainUpdates

Returns

ApplyChainUpdates

Inherited from

SolanaOperation< ApplyChainUpdatesParams, UnsignedSolanaTx, ParsedApplyChainUpdatesParams >.constructor

Properties

name

readonly name: "applyChainUpdates" = 'applyChainUpdates'

Defined in: cct/solana/token-pool/operations/apply-chain-updates.ts:217

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, params: ParsedApplyChainUpdatesParams): Promise<UnsignedSolanaTx>

Defined in: cct/solana/token-pool/operations/apply-chain-updates.ts:320

Builds all instructions in contract-equivalent order as one unsigned transaction.

Parameters

Parameter	Type
chain	SolanaChain
params	ParsedApplyChainUpdatesParams

Returns

Promise<UnsignedSolanaTx>

Overrides

SolanaOperation.buildUnsigned

---

execute()

execute(_chain: SolanaChain, _params: ExecuteApplyChainUpdatesParams): Promise<TransactionResult>

Defined in: cct/solana/token-pool/operations/apply-chain-updates.ts:361

Unsupported because this operation may require multiple transactions.

Parameters

Parameter	Type
_chain	SolanaChain
_params	ExecuteApplyChainUpdatesParams

Returns

Promise<TransactionResult>

See

executeBatch.

Overrides

SolanaOperation.execute

---

executeBatch()

executeBatch(chain: SolanaChain, params: ExecuteApplyChainUpdatesParams): Promise<ExecuteApplyChainUpdatesResult>

Defined in: cct/solana/token-pool/operations/apply-chain-updates.ts:369

Signs, submits, and confirms each packed transaction, returning every transaction hash.

Parameters

Parameter	Type
chain	SolanaChain
params	ExecuteApplyChainUpdatesParams

Returns

Promise<ExecuteApplyChainUpdatesResult>

---

generate()

generate(_chain: SolanaChain, _params: GenerateApplyChainUpdatesParams): Promise<UnsignedSolanaTx>

Defined in: cct/solana/token-pool/operations/apply-chain-updates.ts:337

Unsupported because this operation may require multiple transactions.

Parameters

Parameter	Type
_chain	SolanaChain
_params	GenerateApplyChainUpdatesParams

Returns

Promise<UnsignedSolanaTx>

See

generateBatch.

Overrides

SolanaOperation.generate

---

generateBatch()

generateBatch(chain: SolanaChain, params: GenerateApplyChainUpdatesParams): Promise<GenerateApplyChainUpdatesResult>

Defined in: cct/solana/token-pool/operations/apply-chain-updates.ts:345

Builds one or more ordered transactions without splitting a per-chain update group.

Parameters

Parameter	Type
chain	SolanaChain
params	GenerateApplyChainUpdatesParams

Returns

Promise<GenerateApplyChainUpdatesResult>

---

parse()

protected parse(params: GenerateApplyChainUpdatesParams): ParsedApplyChainUpdatesParams

Defined in: cct/solana/token-pool/operations/apply-chain-updates.ts:220

Validates the batch envelope; component operations validate each chain update.

Parameters

Parameter	Type
params	GenerateApplyChainUpdatesParams

Returns

ParsedApplyChainUpdatesParams

Overrides

SolanaOperation.parse

---

prepare()

protected prepare(params: SolanaGenerateParams): ParsedApplyChainUpdatesParams

Defined in: cct/operation.ts:48

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

Parameters

Parameter	Type
params	SolanaGenerateParams

Returns

ParsedApplyChainUpdatesParams

Inherited from

SolanaOperation.prepare

---

prepareWalletExecution()

protected prepareWalletExecution(params: SolanaExecuteParams<ApplyChainUpdatesParams>): { computeUnits: number | undefined; parsed: ParsedApplyChainUpdatesParams; 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<ApplyChainUpdatesParams>

Returns

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

computeUnits

computeUnits: number | undefined

parsed

parsed: ParsedApplyChainUpdatesParams

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
