deploy_multichain_lagoon_vault

Documentation for eth_defi.erc_4626.vault_protocol.lagoon.deployment.deploy_multichain_lagoon_vault function.

deploy_multichain_lagoon_vault(*, chain_web3, deployer, config, cctp_enabled=False, max_workers=None)

Deploy Lagoon vaults across multiple chains with a shared deterministic Safe.

Uses CREATE2 via the canonical Safe v1.4.1 ProxyFactory to produce the same Safe address on every chain. Each chain gets its own vault and guard deployment, but all vaults share the same Safe multisig address.

Deploys all chains in parallel using threads to minimise wall-clock time.

If cctp_enabled is True, CCTP whitelisting is automatically configured per chain. Chains without CCTP support (e.g. HyperEVM) are silently skipped.

Parameters

• chain_web3 (dict[str, web3.main.Web3]) – Mapping of chain names (lowercase, matching eth_defi.chain.CHAIN_NAMES) to Web3 instances. Example: {"ethereum": w3_eth, "arbitrum": w3_arb}.

• deployer (eth_account.signers.local.LocalAccount) – The deployer account. A separate HotWallet is created per chain for nonce management.

• config (eth_defi.erc_4626.vault_protocol.lagoon.deployment.LagoonConfig) – Shared LagoonConfig. Must have safe_salt_nonce set. The parameters.underlying field is auto-resolved per chain from eth_defi.token.USDC_NATIVE_TOKEN if set to a zero/empty address.

• cctp_enabled (bool) – If True, auto-create CCTPDeployment per chain using CCTPDeployment.create_for_chain(). Chains not in CHAIN_ID_TO_CCTP_DOMAIN are silently skipped.

• max_workers (int | None) – Maximum number of parallel deployment threads. Defaults to the number of chains.

Returns

LagoonMultichainDeployment with per-chain results.
