Class: SetSiloRebalancer

Defined in: cct/evm/token-pool/operations/set-silo-rebalancer.ts:76

Appoints one lane's silo rebalancer on a siloed pool (v1.6.0–v1.6.1). Owner-only.

Constructor

new SetSiloRebalancer(): SetSiloRebalancer

Returns

SetSiloRebalancer

Properties

name

readonly name: "setSiloRebalancer" = 'setSiloRebalancer'

Defined in: cct/evm/token-pool/operations/set-silo-rebalancer.ts:77

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

EVMOperation.name

Methods

buildUnsigned()

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

Defined in: cct/evm/token-pool/operations/set-silo-rebalancer.ts:120

Resolves the pool's type/version, floor-matches the encoder, rejects a zero rebalancer on a v1.6.0 pool, confirms the lane is siloed, then that sender (when given) is the pool owner.

Parameters

Parameter	Type
chain	EVMChain
params	SetSiloRebalancerParams

Returns

Promise<UnsignedEVMTx>

Remarks

The zero-address check needs only the version, so it costs no RPC. The lane check is a property of the pool and runs with or without sender. Both live here, not in execute, so the offline / multisig path gets them too.

Throws

CCTContractTypeInvalidError if the pool is not a SiloedLockReleaseTokenPool

Throws

CCTOperationUnsupportedError on a v2.0.0 pool

Throws

CCTParamsInvalidError if rebalancer is zero on a v1.6.0 pool, the lane is not siloed, or sender is given and is not the pool owner

Throws

CCTContractVersionUnsupportedError if the pool reports an unknown version

execute()

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

Defined in: cct/evm/token-pool/operations/set-silo-rebalancer.ts:151

Signs and submits as the pool owner, defaulting sender to the signing wallet: the only address that can satisfy buildUnsigned's owner check for a broadcast tx. See EVMOperation.resolveWalletSender for why a divergent sender is rejected rather than signed.

Parameters

Parameter	Type
chain	EVMChain
params	EVMExecuteParams<SetSiloRebalancerParams>

Returns

Promise<TransactionResult>

Throws

CCIPWalletInvalidError if wallet is not a valid signer

Throws

CCTParamsInvalidError if sender is given and is not the wallet's address, or the wallet is not the pool owner

Throws

CCIPExecTxRevertedError if the tx reverts on-chain

Overrides

EVMOperation.execute

generate()

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

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

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

Parameters

Parameter	Type
chain	EVMChain
params	SetSiloRebalancerParams

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: SetSiloRebalancerParams): SetSiloRebalancerParams

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	SetSiloRebalancerParams

Returns

SetSiloRebalancerParams

Inherited from

EVMOperation.parse

---

prepare()

protected prepare(params: SetSiloRebalancerParams): SetSiloRebalancerParams

Defined in: cct/operation.ts:48

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

Parameters

Parameter	Type
params	SetSiloRebalancerParams

Returns

SetSiloRebalancerParams

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

EVMOperation.resolveWalletSender

validate()

protected validate(__namedParameters: SetSiloRebalancerParams): void

Defined in: cct/evm/token-pool/operations/set-silo-rebalancer.ts:92

Validates the pool, lane and rebalancer before any RPC. A zero rebalancer passes here: only the pool's version decides whether it is allowed.

Parameters

Parameter	Type
__namedParameters	SetSiloRebalancerParams

Returns

void

Overrides

EVMOperation.validate
