SecuritizeVault

Documentation for eth_defi.tokenised_fund.securitize.vault.SecuritizeVault Python class.

class SecuritizeVault

Bases: eth_defi.vault.base.VaultBase

Scan-only adapter for Securitize DS Protocol tokenised securities.

The adapter reads share supply from the ERC-20-compatible token. BUIDL has an explicit one-USD NAV estimate; recognised variable-NAV funds read a reviewed RedStone on-chain push feed at the same archive block.

Create a Securitize DSToken adapter.

Parameters
  • web3 – Web3 connection.

  • spec – Chain and DSToken address.

  • token_cache – ERC-20 token metadata cache.

  • features – Shared pipeline feature flags.

  • default_block_identifier – Default metadata block, retained for adapter compatibility.

  • require_denomination_token – Whether a missing ERC-20 denomination is an error.

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

fetch_available_liquidity(block_identifier='latest')

Get the amount of denomination token available for immediate withdrawal.

Only applicable to lending protocol vaults (IPOR, Euler, Morpho, Gearbox, etc.). Non-lending protocols should leave this method unimplemented.

Note: maxRedeem(address(0)) does NOT work as a proxy for available liquidity because it requires a specific address that has already deposited shares. For address(0), balanceOf is always 0, so maxRedeem returns 0 regardless of actual liquidity.

Parameters

block_identifier (Union[Literal['latest', 'earliest', 'pending', 'safe', 'finalized'], eth_typing.evm.BlockNumber, eth_typing.evm.Hash32, eth_typing.encoding.HexStr, int]) – Block to query. Defaults to “latest”.

Raises

NotImplementedError – For non-lending protocol vaults.

Returns

Amount in denomination token units (human-readable Decimal).

Return type

Optional[decimal.Decimal]

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_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_utilisation_percent(block_identifier='latest')

Get the percentage of assets currently lent out.

Only applicable to lending protocol vaults (IPOR, Euler, Morpho, Gearbox, etc.). Non-lending protocols should leave this method unimplemented.

Parameters

block_identifier (Union[Literal['latest', 'earliest', 'pending', 'safe', 'finalized'], eth_typing.evm.BlockNumber, eth_typing.evm.Hash32, eth_typing.encoding.HexStr, int]) – Block to query. Defaults to “latest”.

Return type

Optional[float]

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_capability()

Return static public transaction-adapter support, if any.

This method deliberately does not attempt to construct a manager or query live pause, cap, epoch, balance, allow-list, or liquidity state. Adapters opt in only after their complete deposit and redemption lifecycles have focused coverage. None is therefore the safe default for unknown and protocol-specific vaults.

Returns

Adapter-specific capability object, or None when unsupported.

Return type

Optional[eth_defi.vault.deposit_redeem.VaultDepositManagerCapability]

get_fee_mode()

Get how this vault accounts its fees.

Return type

Optional[eth_defi.vault.fee.VaultFeeMode]

get_flags()

Get various vault state flags from the smart contract.

Returns

Flag set.

Do not modify in place.

Return type

set[eth_defi.vault.flag.VaultFlag]

get_notes()

Get a human readable message if we know somethign special is going on with this vault.

Return type

Optional[str]

str

get_risk()

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_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

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

property share_token: eth_defi.token.TokenDetails

ERC-20 that presents vault shares.

  • User gets shares on deposit and burns them on redemption

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.
