class CCTPDeployment

Bases: object

CCTP V2 deployment configuration for guard whitelisting.

All CCTP V2 contracts share the same address across EVM chains (CREATE2), so this mainly configures which destination domains are allowed.

Attributes summary

`token_messenger`	TokenMessengerV2 contract address
`message_transmitter`	MessageTransmitterV2 contract address
`token_minter`	TokenMinterV2 contract address
`allowed_destination_domains`	CCTP domain IDs of allowed destination chains.

Methods summary

`__init__`([token_messenger, ...])
`create_for_chain`(chain_id[, ...])	Create a CCTP deployment configuration for a given chain.

token_messenger: eth_typing.evm.HexAddress: TokenMessengerV2 contract address

message_transmitter: eth_typing.evm.HexAddress: MessageTransmitterV2 contract address

allowed_destination_domains: list[int]: CCTP domain IDs of allowed destination chains. Use eth_defi.cctp.constants.CHAIN_ID_TO_CCTP_DOMAIN to convert chain IDs to domain IDs.

classmethod create_for_chain(chain_id, allowed_destinations=None)

Create a CCTP deployment configuration for a given chain.

Parameters

chain_id (int) – EVM chain ID of the source chain (e.g. 1 for Ethereum).
allowed_destinations (list[int] | None) – List of EVM chain IDs for allowed destination chains. Automatically converted to CCTP domain IDs. If None, no destinations are allowed (add them separately).

Returns

Configured CCTPDeployment instance.

Raises

ValueError – If the source chain or a destination chain is not supported.
