Wallet Balance Filter

The wallet balance filter selects the native asset balance of the on-chain wallet as a constraint for transaction risk control, restricting outbound movements of the wallet’s native currency.

I. Filter Positioning​

The wallet balance filter is the most fundamental and core layer in the asset filtering system.

It directly operates on the wallet’s own native asset balance, limiting the most direct and visible asset outflows, and serves as the first line of defense in the overall asset security architecture.

II. Target Scope​

  • The native asset balance of the current on-chain wallet
  • For example: the SOL native currency

This filter focuses solely on changes to the wallet’s own balance and does not involve tokens or assets held by other accounts.

III. Parameters​

  • No additional parameters
  • By default, it monitors and constrains changes to the wallet’s native asset balance

IV. Typical Use Cases​

  • Limiting the maximum amount of native currency (e.g., SOL) that can be transferred in a single transaction
  • Preventing the wallet’s native assets from being drained in a single operation due to mistakes or malicious transactions
