prepare_probe_deposit_request

Documentation for eth_defi.erc_4626.deposit_probe.prepare_probe_deposit_request function.

prepare_probe_deposit_request(manager, owner, raw_amount, capability_data, max_deposit_guidance)

Prepare one manager request and convert expected refusal to probe data.

Protocol managers use VaultFlowError for known pre-broadcast denials such as a whitelist rejection. These are per-vault probe results, not pipeline failures, and must not abort the remaining candidate sweep.

Parameters

• manager (eth_defi.vault.deposit_redeem.VaultDepositManager) – Protocol deposit manager selected for the candidate.

• owner (eth_typing.evm.HexAddress) – Probe vault that will own and receive the deposit.

• raw_amount (int) – Deposit amount in denomination-token raw units.

• capability_data (dict[str, object]) – Scanner capability metadata copied to the probe result.

• max_deposit_guidance (str) – Informational ERC-4626 capacity response.

Returns

Prepared request and no failure, or no request and a persistent flow_unavailable/adapter_error result.

Return type

tuple[eth_defi.vault.deposit_redeem.DepositRequest | None, dict[str, object] | None]
