Glossary

Cross-reference: each term links to the concept page that explains it in context.

A

Accrued fee. Node-operator fees accumulated against a vault, claimable via disburse-fee. API field: vaultData.accruedFee. See Fee model.

Allowlist. The set of addresses holding DEPOSIT_ROLE on a permissioned pool vault. See Staking pools → Allowlist.

allowList vs allowlistEnabled. Same underlying state, different field names by convention. The vault returns allowList: true on reads; pool creation accepts allowlistEnabled: true on writes. Both refer to whether the pool enforces DEPOSIT_ROLE membership for deposits.

Allowlist manager. The address holding ALLOW_LIST_MANAGER_ROLE: authorized to add and remove allowlist members.

B

Basis points (BP). Unit for fee rates. 1 BP = 0.01%. 100 BP = 1%. The nodeOperatorFeeBP field uses this unit.

D

Dashboard. The control-surface contract for a Lido v3 vault. Role administration, fee settlement, and validator triggers all go through the Dashboard. See Staking vaults.

Dedicated vault. A Lido v3 stVault with a single owner. The default vault shape. Available in both SVM and SVM Pro.

DEPOSIT_ROLE. Pool-contract role; holders can deposit into a permissioned pool. The allowlist is the set of addresses holding this role.

DEFAULT_ADMIN_ROLE. Top-level on-chain role on the Dashboard. Holders can grant and revoke all other roles.

F

feesToSettle. Outstanding Lido protocol fees owed to the treasury for a vault. API path: vaultData.obligations.feesToSettle. Settled via settle-lido-fees.

Finalize. Step in the withdrawal flow where the queue makes requested withdrawals claimable. See Withdrawals.

I

is_pro_svm_user. Account-level flag returned by GET /v1/account. When true, SVM Pro features are available. Provisioned by Northstake.

L

Lido v3 (stVaults). The smart-contract substrate Northstake builds on. See Lido v3 primer.

Linked wallet. An external wallet paired to a Northstake account, available for signing operations.

M

MFA step-up. Re-authentication required for sensitive API operations. Marked by x-mfaApiScope in the OpenAPI spec.

Myrmidon. One of the validator providers Northstake supports. See Supported staking providers.

N

Node operator. The provider running validator software for a vault. Holds NODE_OPERATOR_MANAGER_ROLE on the Dashboard. See Supported staking providers and Roles and permissions.

nodeOperatorFeeBP. The node-operator fee rate on a vault, in basis points. Set at creation; updated via set-fee-rate (Pro).

O

Operator grid. Northstake-managed mapping of which validator providers are available to which account. Determines what shows up in the Add Vault wizard.

Owner. The address that owns a vault, holding DEFAULT_ADMIN_ROLE.

P

PDG (Predeposit Guarantee). Lido v3 mechanism for safely reserving a validator slot before the full 32 ETH is committed. See Validator lifecycle.

pdgState. A validator's PDG state: predeposited, proven, or activated. Drives eligibility for the Activate flow.

Permissioned pool. A pool vault with allowList: true. Deposits gated by an allowlist.

Pool vault. A Lido v3 vault that mints an ERC-20 LP token to depositors. Two sub-types: stv and stvSteth. SVM Pro only.

Predeposited. PDG state where a 1 ETH predeposit has been made but not yet proven on-chain.

Proven. PDG state where the predeposit has been proven; the validator is eligible for activation.

R

Report (vault-hub report). Periodic snapshot of a vault's state published by the Lido vault hub. Updates fee obligations and validates reserve ratios.

report_update_available. Webhook event fired when a new vault-hub report is available.

S

Share limit. A vault's maximum stETH minting capacity, managed via tier settings.

Staking Vault. The Lido v3 contract that holds ETH and validator keys. One per vault.

Step-up MFA. See MFA step-up.

stv. Generic pool-vault sub-type (LP token).

stvSteth. Pool-vault sub-type with native stETH integration.

SVM. Staking Vault Manager: Northstake's control surface for Lido v3 vaults.

SVM Pro. The expanded version of SVM. Unlocks pool vaults, allowlist management, fee settlement, webhooks, and tier management. Gated by is_pro_svm_user.

T

Tier. A vault's slot on the Lido operator grid, controlling its share limit. Managed via the Tier Settings modal (Pro).

Timelock. Contract that enforces a delay between proposing and executing sensitive operations on a vault. Pro-typical.

V

Validator. A Lido v3 staking validator. Identified by index and BLS public key. Goes through pending → active → exited → withdrawn.

Vault hub. Lido v3 system component that publishes reports and tracks vault obligations.

W

Webhook. Push notification for vault events. Subscriptions managed at the account level (Pro).

Withdrawal queue. Per-vault contract handling withdrawal requests, claims, and finalization. See Withdrawals.
