Adding & Removing Components

Components are the vaults and strategies where a Node deploys assets. Each component must be validated and whitelisted before being added to a Node. This section covers the complete lifecycle of component management, from addition and configuration to removal.

Adding Components

function addComponent(
    address component,
    uint64 targetWeight,
    uint64 maxDelta,
    address router
) external onlyOwner onlyWhenNotRebalancing

Security Checks

1. Component must:

   • Not be zero address

   • Not already be a component

   • Have same underlying asset as Node

   • Be whitelisted in specified Router

2. Router must:

   • Be whitelisted in Node

   • Be whitelisted in Registry

3. Timing:

   • Cannot add during rebalance window

Example Usage

// As Node owner
node.addComponent(
    vaultAddress,      // ERC4626 or ERC7540 vault
    0.4e18,           // 40% target allocation
    0.05e18,          // 5% maximum deviation
    router4626Address  // Router for this component type
);

Removing Components

function removeComponent(
    address component,
    bool force
) external onlyOwner onlyWhenNotRebalancing

Security Checks

1. Component must:

   • Be registered component

   • Have zero balance (unless force=true)

2. Timing:

   • Cannot remove during rebalance window

Best Practices

1. Update allocation to zero first:

node.updateComponentAllocation(
    component,
    0,              // zero target weight
    0,              // zero max delta
    routerAddress
);

1. Wait for rebalancer to exit position

2. Remove component:

node.removeComponent(component, false);

Component Validation

Components and their allocations must:

• Sum to 100% (1e18) with reserve ratio

• Use whitelisted routers

• Match Node's underlying asset

• Be whitelisted in their respective routers

These checks are enforced during:

• Component addition

• Allocation updates

• Rebalance initiation

Governance & Whitelisting

NashPoint implements a multi-tiered permissioning system to protect Nodes from misconfiguration or malicious components. Each router and component must be approved at protocol, router, and node levels before use.
