Classes

ShiftVaultProduct

One published ShiftVault deployment.

class ShiftVaultProduct

Bases: object

One published ShiftVault deployment.

Shift publishes its current vault addresses in its public address registry. The contracts are custom ERC-20 share vaults, so the registry is deliberately chain-aware instead of relying on an ERC-4626 interface probe.

Parameters

chain_id – EVM chain identifier hosting the vault.
vault_address – ShiftVault ERC-20 share-token contract address.
product_name – Public Shift product name.
first_seen_at_block – First EVM block with vault bytecode.
first_seen_at – Naive UTC timestamp of first_seen_at_block.

__init__(chain_id, vault_address, product_name, first_seen_at_block, first_seen_at)

Parameters

chain_id (int) –
vault_address (eth_typing.evm.HexAddress) –
product_name (str) –
first_seen_at_block (int) –
first_seen_at (datetime.datetime) –

Return type

None
