class MorphoV1Vault

Bases: eth_defi.erc_4626.vault.ERC4626Vault

Morpho Vault V1 (MetaMorpho) support.

Morpho V1 vaults directly integrate with Morpho markets. They are identified by the MORPHO() function call which returns the address of the Morpho protocol contract.

See also eth_defi.erc_4626.vault_protocol.morpho.vault_v2.MorphoV2Vault for the newer adapter-based architecture.

Parameters

web3 – Connection we bind this instance to
spec – Chain, address tuple

default_block_identifier –
Override block identifier for on-chain metadata reads.

When None, use get_safe_cached_latest_block_number() (the default, safe for broken RPCs). Set to "latest" for freshly deployed vaults whose contracts do not exist at the safe-cached block.
require_denomination_token – If True, accessing denomination_token will raise RuntimeError when the on-chain lookup returns None.

Returns: Set of warning type strings, e.g. {"short_timelock", "not_whitelisted"}. Empty set if no data available.
Return type: set[str]

get_morpho_market_flags()

Return warning type strings from Morpho API warnings on underlying markets.

Market-level warnings cover financial risk in the vault’s market allocations: bad_debt_unrealized (RED), bad_debt_realized (YELLOW), oracle_price_derivation, not_whitelisted.

Returns: Set of warning type strings, e.g. {"bad_debt_unrealized"}. Empty set if no data available.
Return type: set[str]

get_notes()

Return a human-readable note about RED-level Morpho warnings, if any.

Checks the hardcoded flag table first (via the base class), then falls back to a dynamically generated note from the Morpho GraphQL API when RED warnings are present.

The generated text follows the form:

"Morpho has flagged this vault with the following issues: bad_debt_unrealized, short_timelock"

Returns: Note string, or None if no hardcoded note and no RED warnings.
Return type: Optional[str]

get_flags()

Get vault flags, adding morpho_issues when RED warnings are detected.

__init__(web3, spec, token_cache=None, features=None, default_block_identifier=None, require_denomination_token=False)

Parameters

web3 (web3.main.Web3) – Connection we bind this instance to
spec (eth_defi.vault.base.VaultSpec) – Chain, address tuple
token_cache (Optional[dict]) –
Cache used with fetch_erc20_details() to avoid multiple calls to the same token.

Reduces the number of RPC calls when scanning multiple vaults.
features (Optional[set[eth_defi.erc_4626.core.ERC4626Feature]]) – Pass vault feature flags along, externally detected.
default_block_identifier (Optional[Union[Literal['latest', 'earliest', 'pending', 'safe', 'finalized'], eth_typing.evm.BlockNumber, eth_typing.evm.Hash32, eth_typing.encoding.HexStr, hexbytes.main.HexBytes, int]]) –

property address: eth_typing.evm.HexAddress: Get the vault smart contract address.

can_check_deposit()

Check if maxDeposit(address(0)) can be used to check global deposit availability.

Most ERC-4626 vaults implement maxDeposit in a way that returns meaningful values when called with address(0):

Returns 0 when deposits are globally closed/capped
Returns a positive value indicating maximum deposit allowed

Override to return False in subclasses where maxDeposit(address(0)) doesn’t provide meaningful global availability information.

Returns: True if maxDeposit(address(0)) returns meaningful values for global deposit availability checking.
Return type: bool

can_check_redeem()

Check if maxRedeem(address(0)) can be used to check global redemption availability.

Most protocols return 0 for maxRedeem(address(0)) because that address has no balance/shares, not because redemptions are closed:

Gearbox: maxRedeem returns min(balanceOf(owner), convertToShares(availableLiquidity))
Most vaults: Return 0 because address(0) has no shares

Some protocols do use maxRedeem(address(0)) meaningfully:

Morpho, IPOR, Plutus: Return 0 when redemptions are globally blocked

Override to return True in subclasses that support address(0) redemption checks.

Returns: True if maxRedeem(address(0)) returns meaningful values for global redemption availability checking.
Return type: bool

property chain_id: int: Chain this vault is on

property denomination_token: Optional[eth_defi.token.TokenDetails]

Get the token which denominates the vault valuation

Used in deposits and redemptions
Used in NAV calculation
Used in profit benchmarks
Usually USDC

Returns

Token wrapper instance.

Maybe None for broken vaults like https://arbiscan.io/address/0x9d0fbc852deccb7dcdd6cb224fa7561efda74411#code

Note

None results are not cached — the next access will retry the on-chain call. This avoids permanently caching a transient RPC failure.

property deposit_manager: eth_defi.vault.deposit_redeem.VaultDepositManager: Deposit manager assocaited with this vault

property description: Optional[str]

Human-readable vault strategy description.

Fetched from protocol-specific offchain sources (e.g. Euler GitHub labels, Lagoon web app API)
Returns None if the protocol does not provide descriptions or the vault is not in the metadata source
Override in subclasses that support offchain metadata

property erc_7540: bool

Is this ERC-7540 vault with asynchronous deposits.

For example previewDeposit() function and other functions will revert

fetch_denomination_token()

Read denomination token from onchain.

Use denomination_token() for cached access.

Return type: Optional[eth_defi.token.TokenDetails]

fetch_denomination_token_address()

Get the asset() denomination token address of this vault.

Results are disk-cached per (chain_id, vault_address) via eth_defi.erc_4626.vault_token when the vault was constructed with a eth_defi.token.TokenDiskCache and no pinned default_block_identifier. The denomination token is immutable post-deployment, so the cached value is correct regardless of which block the caller would have asked for.

Only a definitive non-null answer is persisted. The None path taken on revert / broken contract is never cached, matching the behaviour of eth_defi.vault.base.VaultBase.denomination_token() which explicitly avoids memoising None so transient failures can be retried.

To disable the cache, pass token_cache=None (or any non- TokenDiskCache dict) when constructing the vault, or construct with a pinned default_block_identifier.

Returns: Denomination token address, or None if the vault contract is broken and did not return a valid address.
Return type: Optional[eth_typing.evm.HexAddress]

fetch_deposit_closed_reason()

Check if deposits are closed using maxDeposit(address(0)).

Uses the ERC-4626 standard maxDeposit function to determine if deposits are available. Returns a human-readable reason with the max deposit amount if deposits are restricted.

Returns: Human-readable string if deposits are closed/restricted, or None if deposits are open (maxDeposit > 0).
Return type: Optional[str]

fetch_deposit_next_open()

Get when deposits will next be open.

For epoch-based vaults (Ostium, D2), return calculated window open time
For non-epoch vaults (Plutus, IPOR, Morpho), return None
Override in protocol-specific subclasses

Returns

Naive UTC datetime when deposits will next be available, or None if:

Deposits are currently open
Timing is unpredictable (manually controlled)
Protocol does not support timing information

Return type

Optional[datetime.datetime]

fetch_info()

Use info() property for cached access.

Returns: See LagoonVaultInfo
Return type: eth_defi.erc_4626.vault.ERC4626VaultInfo

fetch_nav(block_identifier=None)

Fetch the most recent onchain NAV value.

In the case of Lagoon, this is the last value written in the contract with updateNewTotalAssets() and ` settleDeposit()`
TODO: updateNewTotalAssets() there is no way to read pending asset update on chain

Returns: Vault NAV, denominated in denomination_token()
Return type: decimal.Decimal

fetch_portfolio(universe, block_identifier=None, allow_fallback=True)

Read the current token balances of a vault.

SHould be supported by all implementations

Parameters

universe (eth_defi.vault.base.TradingUniverse) –
block_identifier (Optional[Union[Literal['latest', 'earliest', 'pending', 'safe', 'finalized'], eth_typing.evm.BlockNumber, eth_typing.evm.Hash32, eth_typing.encoding.HexStr, hexbytes.main.HexBytes, int]]) –
allow_fallback (bool) –

Return type

eth_defi.vault.base.VaultPortfolio

fetch_redemption_closed_reason()

Check if redemptions are closed using maxRedeem(address(0)).

Only works for protocols that implement maxRedeem in a way that returns meaningful values for address(0). Most protocols return 0 because address(0) has no shares, not because redemptions are closed.

Returns: Human-readable string if redemptions are closed, or None if redemptions are open or check is not supported.
Return type: Optional[str]

fetch_redemption_next_open()

Get when withdrawals/redemptions will next be open.

For epoch-based vaults (Ostium, D2), return calculated window open time
For non-epoch vaults (Plutus, IPOR, Morpho), return None
Override in protocol-specific subclasses

Returns

Naive UTC datetime when withdrawals will next be available, or None if:

Withdrawals are currently open
Timing is unpredictable (manually controlled)
Protocol does not support timing information

Return type

Optional[datetime.datetime]

fetch_scan_record_extra_data()

Fetch protocol-specific private scan row columns.

Some vault protocols expose structured metadata that is useful for the raw scanner output but does not fit the shared human-readable columns. Override this hook in protocol-specific subclasses instead of adding a separate branch to eth_defi.erc_4626.scan.create_vault_scan_record().

Returns: Mapping of private scan-row column names, usually prefixed with _. The default implementation returns no extra data.
Return type: dict[str, object]

fetch_share_price(block_identifier)

Get the current share price.

Returns

The share price in underlying token.

If supply is zero return zero.

Parameters

block_identifier (Union[Literal['latest', 'earliest', 'pending', 'safe', 'finalized'], eth_typing.evm.BlockNumber, eth_typing.evm.Hash32, eth_typing.encoding.HexStr, hexbytes.main.HexBytes, int]) –

Return type

decimal.Decimal

fetch_share_token()

Read share token details onchain.

Use share_token() for cached access.

Return type: eth_defi.token.TokenDetails

fetch_share_token_address(block_identifier='latest')

Get share token of this vault.

Vault itself (ERC-4626)
share() accessor (ERC-7575)

Results are disk-cached per (chain_id, vault_address) via eth_defi.erc_4626.vault_token when the vault was constructed with a eth_defi.token.TokenDiskCache. Under normal circumstances the block_identifier argument is effectively ignored on cache hits — ERC-4626 share tokens are immutable post-deployment, so the cached value is correct regardless of which block the caller asked for.

Only a definitive answer from the chain is ever persisted: a successful call, or a revert matching KNOWN_SHARE_TOKEN_ERROR_MESSAGES (which positively classifies the contract as non-ERC-7575). Transient RPC failures (ProbablyNodeHasNoBlock, HTTP 502) fall back to self.vault_address but are not written to the cache, so a flaky node cannot poison a real ERC-7575 vault’s entry.

To disable the cache, pass token_cache=None (or any non- TokenDiskCache dict) when constructing the vault, or construct with a pinned default_block_identifier to force the uncached historical-read path on every call.

Parameters: block_identifier (Union[Literal['latest', 'earliest', 'pending', 'safe', 'finalized'], eth_typing.evm.BlockNumber, eth_typing.evm.Hash32, eth_typing.encoding.HexStr, hexbytes.main.HexBytes, int]) – Block to query. Cache is only consulted/written when the caller passes the default "latest" and the vault instance has no pinned default_block_identifier.
Return type: eth_typing.evm.HexAddress

fetch_total_assets(block_identifier)

What is the total NAV of the vault.

Example:

assert vault.denomination_token.symbol == "USDC"
assert vault.share_token.symbol == "ipUSDCfusion"
assert vault.fetch_total_assets(block_identifier=test_block_number) == Decimal("1437072.77357")
assert vault.fetch_total_supply(block_identifier=test_block_number) == Decimal("1390401.22652875")

Parameters

Block number to read.

Use web3.eth.block_number for the last block.

Returns

The vault value in underlyinh token

Return type

Optional[decimal.Decimal]

fetch_total_supply(block_identifier)

What is the current outstanding shares.

Example:

Parameters

Return type: eth_defi.erc_4626.vault.ERC4626VaultInfo

property flow_manager: eth_defi.vault.base.VaultFlowManager: Flow manager associated with this vault

get_deposit_fee(block_identifier)

Deposit fee is set to zero by default as vaults usually do not have deposit fees.

Internal: Use get_fee_data().

Parameters: block_identifier (Union[Literal['latest', 'earliest', 'pending', 'safe', 'finalized'], eth_typing.evm.BlockNumber, eth_typing.evm.Hash32, eth_typing.encoding.HexStr, int]) –
Return type: Optional[float]

get_deposit_manager()

Get deposit manager to deposit/redeem from the vault.

Return type: ERC4626DepositManager

get_deposit_manager_capability()

Declare the exact generic ERC-4626 implementation’s two-way flow.

Subclasses need exact-type inclusion in CERTIFIED_SYNCHRONOUS_DEPOSIT_MANAGER_CLASSES. The guarded probe may separately use supports_generic_deposit_manager() as a temporary fallback without advertising it as public metadata.

Returns: Synchronous two-way capability for the exact base class, otherwise None.
Return type: Optional[eth_defi.vault.deposit_redeem.VaultDepositManagerCapability]

get_fee_data()

Get fee data structure for this vault.

Raises: ValueError – In the case of broken or unimplemented fee reading methods in the smart contract
Return type: eth_defi.vault.fee.FeeData

get_fee_mode()

Get how this vault accounts its fees.

Return type: Optional[eth_defi.vault.fee.VaultFeeMode]

get_flow_manager()

Get flow manager to read indiviaul settle events.

Only supported if has_block_range_event_support() is True

Return type: eth_defi.vault.base.VaultFlowManager

get_protocol_name()

Return the name of the vault protocol.

Return type: str

get_risk()

Get risk profile of this vault.

Return type: Optional[eth_defi.vault.risk.VaultTechnicalRisk]

get_synchronous_deposit_manager_capability()

Build static metadata for a verified synchronous manager.

A caller must already have established the reader class’ guarded fork evidence. This deliberately performs no RPC reads: the capability is static library metadata, not a live vault availability check.

Returns: Synchronous two-way capability.
Return type: eth_defi.vault.deposit_redeem.VaultDepositManagerCapability

get_withdraw_fee(block_identifier)

Withdraw fee is set to zero by default as vaults usually do not have withdraw fees.

Internal: Use get_fee_data().

Parameters: block_identifier (Union[Literal['latest', 'earliest', 'pending', 'safe', 'finalized'], eth_typing.evm.BlockNumber, eth_typing.evm.Hash32, eth_typing.encoding.HexStr, int]) –
Return type: float

has_block_range_event_support()

Does this vault support block range-based event queries for deposits and redemptions.

If not we use chain balance polling-based approach

has_custom_fees()

Does this vault have fees outside the shared fee model.

Custom fees cause risk in vault comparison because the shared management/performance/deposit/withdraw fee fields cannot describe the full fee structure.

Do not return True merely because a vault implements custom accessors for ordinary management, performance, deposit, or withdraw fees. Return True only when some vault fee cannot be reflected in those standard fields as a fee-like value.

Returns: True if the vault has fees outside the shared fee model.
Return type: bool

has_deposit_distribution_to_all_positions()

Deposits go automatically to all open positions.

Deposits do not land into the vault as cash
Instead, smart contracts automatically increase all open positions
The behaviour of Velvet Capital

property info: eth_defi.vault.base.VaultInfo

Get info dictionary related to this vault deployment.

Get cached data on the various vault parameters

Returns: Vault protocol specific information dictionary

is_account_whitelisted(address)

Determine whether an account belongs to the vault deposit policy.

The result concerns policy membership only. A protocol may still require scheduling, an allowance, available capacity, or an open epoch before a deposit can be submitted. Callers must use the relevant deposit manager pre-flight before broadcasting a transaction.

Parameters: address (eth_typing.evm.HexAddress) – Account whose deposit-policy membership is queried.
Returns: True when the account belongs to the applicable policy.
Raises: NotImplementedError – If the adapter cannot safely query account membership.
Return type: bool

is_valid()

Check if this vault is valid.

Call a known smart contract function to verify the function exists

Return type: bool

is_whitelisted_deposit()

Determine whether this vault applies a deposit whitelist policy.

Protocol adapters override this predicate only when their deployed contract version exposes a reliable vault-wide policy read. True means the vault requires account permission; False means its policy is permissionless. This is independent of a caller’s current balance, allowance, pause state, capacity, and request lifecycle.

Returns: True for a whitelist-restricted vault and False for a permissionless vault.
Raises: NotImplementedError – If the adapter cannot safely determine the policy.
Return type: bool

property name: str: Vault name.

property share_token: eth_defi.token.TokenDetails

ERC-20 that presents vault shares.

User gets shares on deposit and burns them on redemption

property short_description: Optional[str]

One-liner vault summary.

Shorter version of description() suitable for listings and tables
Returns None if not available
Override in subclasses that support offchain metadata

supports_generic_deposit_manager()

Check whether the live vault exposes the standard ERC-4626 surface.

This is deliberately an interface check, not a public support claim. Callers must still execute a guarded fork probe before relying on the generic manager for a protocol-specific adapter.

Returns: True when asset succeeds with a non-zero asset address. Deposit and redemption availability is established only by a guarded fork transaction, not by ERC-4626 max* advisory values.
Return type: bool

property symbol: str: Vault share token symbol

property underlying_token: eth_defi.token.TokenDetails: Alias for denomination_token()

property vault_contract: web3.contract.contract.Contract: Get vault deployment.

first_seen_at_block: Optional[int]

Block number hint when this vault was deployed.

Must be set externally, as because of shitty Ethereum RPC we cannot query this. Allows us to avoid unnecessary work when scanning historical price data.
