Defined in: cct/evm/token/operations/grant-mint-and-burn-roles.ts:34

Grants both mint and burn roles on a supported CCT token.

Constructors

Constructor

new GrantMintAndBurnRoles(): GrantMintAndBurnRoles

Returns

GrantMintAndBurnRoles

Inherited from

EVMOperation<GrantMintAndBurnRolesParams>.constructor

Properties

name

readonly name: "grantMintAndBurnRoles" = 'grantMintAndBurnRoles'

Defined in: cct/evm/token/operations/grant-mint-and-burn-roles.ts:35

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

Overrides

EVMOperation.name

Methods

buildUnsigned()

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

Defined in: cct/evm/token/operations/grant-mint-and-burn-roles.ts:65

Reads both role states, then — when sender is known — confirms it owns the token. Rejected only when the account holds both roles already: holding one still builds, since completing the pair is what this call is for.

The role reads run first because they are also the family check (resolveTokenRoleHandler), which owner() cannot make: a token pool and a v2.0.0 CrossChainToken declare owner() too, and v2.0.0 declares grantMintAndBurnRoles itself. Both checks run here rather than in execute, so the offline / multisig path gets them.

Parameters

Parameter	Type
chain	EVMChain
params	GrantMintAndBurnRolesParams

Returns

Promise<UnsignedEVMTx>

Throws

CCTContractTypeInvalidError if tokenAddress is neither a BurnMintERC677 token nor a supported CrossChainToken

Throws

CCTContractVersionUnsupportedError if CrossChainToken reports an unsupported version

Throws

CCTParamsInvalidError if burnAndMinter already holds both roles, or sender lacks the version's role-admin permission

Overrides

execute()

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

Returns

Promise<TransactionResult>

Inherited from

EVMOperation.execute

---

generate()

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

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

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

Parameters

Parameter	Type
chain	EVMChain
params	GrantMintAndBurnRolesParams

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

---

parse()

protected parse(params: GrantMintAndBurnRolesParams): GrantMintAndBurnRolesParams

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	GrantMintAndBurnRolesParams

Returns

GrantMintAndBurnRolesParams

Inherited from

EVMOperation.parse

---

prepare()

protected prepare(params: GrantMintAndBurnRolesParams): GrantMintAndBurnRolesParams

Defined in: cct/operation.ts:48

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

Parameters

Parameter	Type
params	GrantMintAndBurnRolesParams

Returns

GrantMintAndBurnRolesParams

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: GrantMintAndBurnRolesParams): void

Defined in: cct/evm/token/operations/grant-mint-and-burn-roles.ts:44

Validates both addresses before any RPC. Neither may be zero: a tx to 0x0 hits no code, and granting roles to 0x0 mines as a no-op nobody can use.

Parameters

Parameter	Type
__namedParameters	GrantMintAndBurnRolesParams

Returns

void
