# What comes with the API

* **Risk.** The Ground Risk Engine takes absolute or velocity-based rules on APY,
  liquidity and utilization, and what should happen when one triggers. Portfolio Wallets
  and MicroVaults carry it; gTokens do not.
* **Reporting.** Track yield and activity for individual wallets through the
  dashboard and API. Explore
  [accounting activity](https://docs.groundtech.co/api-reference/list-accounting-activity.md),
  [yield period summaries](https://docs.groundtech.co/api-reference/get-accounting-yield-period-summary.md) and
  [computed yield](https://docs.groundtech.co/api-reference/compute-yield.md).
* **Custody.** Every implementation is non-custodial. Signing keys stay with your
  organization or your users; Ground never holds them.
  [Security](https://docs.groundtech.co/docs/security/custody-model.md) covers the signing model, wallet types per
  chain and the independent review.
* **Chains.** Ground handles routing and bridging across
  [supported chains](https://docs.groundtech.co/docs/portfolio-wallets/supported-chains.md), so you do not need to
  move assets off the chain you are already on.
