Class: BeginDefaultAdminTransfer

Defined in: cct/evm/token/operations/begin-default-admin-transfer.ts:90

Proposes a new token admin: v2 beginDefaultAdminTransfer, v1 Ownable2Step transferOwnership.

Constructors

Constructor

new BeginDefaultAdminTransfer(): BeginDefaultAdminTransfer

Returns

BeginDefaultAdminTransfer

Inherited from

EVMOperation<BeginDefaultAdminTransferParams>.constructor

Properties

name

readonly name: "beginDefaultAdminTransfer" = 'beginDefaultAdminTransfer'

Defined in: cct/evm/token/operations/begin-default-admin-transfer.ts:91

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

Overrides

EVMOperation.name

Methods

buildUnsigned()

protected buildUnsigned(chain: EVMChain, params: BeginDefaultAdminTransferParams): Promise<UnsignedEVMTx>

Defined in: cct/evm/token/operations/begin-default-admin-transfer.ts:110

Confirms the current admin (v2 defaultAdmin(), v1 owner()) and, when known, that sender is it. v1 also rejects a zero newAdmin or the current owner. On v2, OpenZeppelin permits replacing an existing pending transfer and permits the zero-address proposal used for renunciation, so neither is rejected here.

Parameters

Parameter	Type
chain	EVMChain
params	BeginDefaultAdminTransferParams

Returns

Promise<UnsignedEVMTx>

Throws

CCTContractVersionUnsupportedError if a CrossChainToken reports an unknown version

Throws

CCTParamsInvalidError if a v2 token has no default admin, sender is not the current admin, or a v1 newAdmin is zero or the current owner

Overrides

EVMOperation.buildUnsigned

---

execute()

execute(chain: EVMChain, params: EVMExecuteParams<BeginDefaultAdminTransferParams>): Promise<TransactionResult>

Defined in: cct/evm/operation.ts:150

generate, then sign and submit; returns the confirmed tx hash.

Parameters

Parameter	Type
chain	EVMChain
params	EVMExecuteParams<BeginDefaultAdminTransferParams>

Returns

Promise<TransactionResult>

Inherited from

EVMOperation.execute

---

generate()

generate(chain: EVMChain, params: BeginDefaultAdminTransferParams): Promise<UnsignedEVMTx>

Defined in: cct/evm/operation.ts:110

Run prepare and buildUnsigned, applying optional sender; no signing.

Parameters

Parameter	Type
chain	EVMChain
params	BeginDefaultAdminTransferParams

Returns

Promise<UnsignedEVMTx>

Remarks

Also pins every built transaction to chain.network.chainId (no RPC, known at construction). This is the one point every CCT builder and both execute paths pass through; unpinned, ethers would infer the chain from the eventual signer's provider.

EVMOperation.generate

parse()

protected parse(params: BeginDefaultAdminTransferParams): BeginDefaultAdminTransferParams

Defined in: cct/operation.ts:42

Normalize validated params for the builder — defaults, conversions, derived values. Identity by default, so an op that needs no normalization declares nothing.

Parameters

Parameter	Type
params	BeginDefaultAdminTransferParams

Returns

BeginDefaultAdminTransferParams

Inherited from

EVMOperation.parse

---

prepare()

protected prepare(params: BeginDefaultAdminTransferParams): BeginDefaultAdminTransferParams

Defined in: cct/operation.ts:48

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

Parameters

Parameter	Type
params	BeginDefaultAdminTransferParams

Returns

BeginDefaultAdminTransferParams

Inherited from

EVMOperation.prepare

---

resolveWalletSender()

protected resolveWalletSender(wallet: unknown, sender?: string): Promise<string>

Defined in: cct/evm/operation.ts:130

Resolves the address a signed submission is authorized against: the signing wallet's own. The chain gates on msg.sender, and submit clears any builder-set tx.from before populating the tx (so ethers' own from/signer guard never fires) — an explicit sender that differs from the wallet would therefore let an op's pre-tx checks authorize one address while a different one actually signs, passing every local guard and reverting on-chain. Ops that gate on an on-chain role call this from execute; build with generateUnsigned* instead when the eventual signer isn't known yet, where sender is trusted as given.

Parameters

Parameter	Type
wallet	unknown
sender?	string

Returns

Promise<string>

Throws

CCIPWalletInvalidError if wallet is not a valid signer

Throws

CCTParamsInvalidError if sender is given and is not the wallet's address

Inherited from

EVMOperation.resolveWalletSender

---

validate()

protected validate(__namedParameters: BeginDefaultAdminTransferParams): void

Defined in: cct/evm/token/operations/begin-default-admin-transfer.ts:94

Validates addresses before any RPC. Zero newAdmin is version-dependent, so checked later.

Parameters

Parameter	Type
__namedParameters	BeginDefaultAdminTransferParams

Returns

void

Overrides

EVMOperation.validate
