# Introduction

**Programmable Capital for AI Agents.**

ASPAN is building a programmable account that combines agent payments and AI-managed yield under the owner's spending, investment, and liquidity rules.

Fund an ASPAN Account, define what your agents may do, and coordinate everyday payments with the management of funds that are not needed immediately. The initial focus is teams with stablecoin balances and recurring compute, data, or API expenses.

### One account, two kinds of permission

**Spending rules** define who an agent may pay, how much it may spend, and when approval is required. **Investment rules** define which strategies may receive funds, exposure limits, and the liquidity that must remain available. Payment authorization does not automatically authorize investing.

The planned account accepts supported stablecoins independently of strategy selection. Buying apUSD, s-apUSD, or Vault shares is an optional investment decision, not a prerequisite for using payments. Supported assets and funding routes will be specified for each release.

### Fund → Set rules → Pay and manage → Review

* **Fund:** add an asset supported by the account's release and payment route.
* **Set rules:** approve spending, investment, and liquidity requirements separately.
* **Pay and manage:** maintain payment liquidity while allocating eligible funds within approved strategies.
* **Review:** inspect payments, allocation decisions, fees, realized returns, and withdrawal outcomes.

AI is intended to help decide how much to reserve, where eligible funds can be allocated, and when to adjust or exit. Independent execution rules must enforce the owner's limits. Investment value and pending withdrawals are not the same as available payment funds.

### Two optional yield paths

[Native ASPAN DeFi](https://docs.aspanfi.com/core-concepts/the-dual-token-model) retains the BNB collateral and apUSD / s-apUSD / xBNB structure. [ASPAN Vaults](https://docs.aspanfi.com/yield-options/aspan-vaults) are a planned, separate option for managing allocations to approved external yield protocols. Both must be evaluated by their underlying risks, net returns, and exit conditions; neither receives an automatic allocation. See [Yield Options](https://docs.aspanfi.com/yield-options/yield-options) for the comparison framework.

### Current status

The programmable account, AI capital management, and external-strategy Vaults are the product direction as of 18 September 2026. The existing prototype demonstrates DeFi and payment flows using sample balances and simulated approvals. It does not establish production account functionality. The initial audit covers the existing DeFi source scope only; see [Smart Contract Security](https://docs.aspanfi.com/risk-management/smart-contract-security).
