# Strategy lifecycle

> Add, remove, and replace strategies in a Meta Vault by separating composition changes from capital movement.

A Meta Vault's strategy set is not fixed at deployment: strategies can be introduced, removed, or replaced as the opportunity set changes. Composition changes (which strategies are whitelisted) and capital movement (where deployed funds actually sit) are separate on-chain actions, gated by separate roles, so a strategy change is reviewable in two clearly distinct steps instead of one opaque transaction.

Steps below name the role whose purpose covers each action (see [Roles and signing models](/documentation/platform/vaults/meta-vaults/vault-mechanics/roles-signing-models)); yield.xyz performs them.

## Add a strategy

<Steps>
  <Step title="Whitelist the strategy">
    The strategist adds the strategy to the vault's set.
  </Step>

  <Step title="Assign a target weight">
    The rebalancer sets its target weight, adjusting other weights and the idle target as needed.
  </Step>

  <Step title="Fund it">
    A rebalance deploys capital into the new strategy to reach its target weight.
  </Step>
</Steps>

A strategy can be whitelisted with a zero weight; that is expected during rollout, before capital is committed to it.

## Remove a strategy

<Steps>
  <Step title="Exit funds">
    The rebalancer pulls capital from the strategy back to idle.
  </Step>

  <Step title="Remove it from the set">
    The strategist removes the strategy from the whitelist.
  </Step>

  <Step title="Redeploy">
    Remaining weights are updated and a rebalance realigns the rest of the portfolio.
  </Step>
</Steps>

<Warning>
  Exit a strategy's funds before removing it from the whitelist. Leaving a meaningful balance behind a removed strategy risks stranding it outside the vault's normal accounting.
</Warning>

## Replace a strategy

Replacement combines the two flows: exit the old strategy's funds, update the whitelist to drop the old strategy and add the new one, set weights that include the replacement, then rebalance to deploy into it. Each step is a separate, role-gated transaction, so a signer reviewing the change sees exactly what moved and when, and the sequence lines up with the audit trail any automated rebalance run also produces.
