Documentation for eth_defi.mellow.flow Python module.

Mellow Core Vault flow manager stubs.

Mellow deposits and redemptions are asynchronous and queue based. The initial adapter intentionally does not expose flow accounting until the queue event ABI and queue-to-vault mapping tests are pinned.

Returns

Never returns until queue scanning is implemented.

Return type

decimal.Decimal

fetch_pending_deposit(block_identifier)

Fetch pending deposit amount.
