Class: AcceptLockboxOwnership

Defined in: cct/evm/lockbox/operations/accept-lockbox-ownership.ts:30

Completes a pending ERC20LockBox ownership transfer via Ownable2Step acceptOwnership.

Constructors

Constructor

new AcceptLockboxOwnership(): AcceptLockboxOwnership

Returns

AcceptLockboxOwnership

Inherited from

EVMOperation<AcceptLockboxOwnershipParams>.constructor

Properties

name

readonly name: "acceptLockboxOwnership" = 'acceptLockboxOwnership'

Defined in: cct/evm/lockbox/operations/accept-lockbox-ownership.ts:31

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

EVMOperation.name

Methods

buildUnsigned()

protected buildUnsigned(chain: EVMChain, __namedParameters: AcceptLockboxOwnershipParams): Promise<UnsignedEVMTx>

Defined in: cct/evm/lockbox/operations/accept-lockbox-ownership.ts:51

Confirms lockbox is a deployed, supported ERC20LockBox, then builds acceptOwnership calldata targeting it.

Parameters

Parameter	Type
chain	EVMChain
__namedParameters	AcceptLockboxOwnershipParams

Returns

Promise<UnsignedEVMTx>

Remarks

The calldata is one fixed selector, so assertLockbox is only there to name a wrong address: a pool or token would accept the same selector and complete its pending transfer instead.

Throws

CCTParamsInvalidError if nothing at lockbox answers typeAndVersion()

Throws

CCTContractTypeInvalidError if lockbox is some other contract, e.g. the pool

Throws

CCTContractVersionUnsupportedError if it reports an unsupported version

Throws

CCIPTypeVersionInvalidError if lockbox answers typeAndVersion() with a string that is not a type version pair

Overrides

EVMOperation.buildUnsigned

execute()

execute(chain: EVMChain, params: EVMExecuteParams<AcceptLockboxOwnershipParams>): 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<AcceptLockboxOwnershipParams>

Returns

Promise<TransactionResult>

Inherited from

EVMOperation.execute

---

generate()

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

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

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

Parameters

Parameter	Type
chain	EVMChain
params	AcceptLockboxOwnershipParams

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.

Inherited from

EVMOperation.generate

prepare()

protected prepare(params: AcceptLockboxOwnershipParams): AcceptLockboxOwnershipParams

Defined in: cct/evm/lockbox/operations/accept-lockbox-ownership.ts:34

Validates the lockbox address before any RPC; there is no other parameter to check.

Parameters

Parameter	Type
params	AcceptLockboxOwnershipParams

Returns

AcceptLockboxOwnershipParams

Overrides

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
