# IOTA

> Network-specific features, signature kinds, supported assets, and integration requirements for IOTA wallets on the Dfns custody platform.

IOTA is a DAG-based distributed ledger with an object-oriented model. This guide covers IOTA-specific features when using Dfns wallets.

## Object model

IOTA uses an **object-based model** where all entities (wallets, assets, UTXOs) are represented as objects. This is similar to Sui's architecture.

### Coins and merging

When you receive IOTA, it creates coin objects. To transfer, you may need to split or merge existing coin objects. Dfns handles this automatically - when you make a transfer, Dfns merges coin objects as needed.

## Staking

IOTA supports native staking with the following mechanics:

### Basic staking

When you stake IOTA:

1. Your IOTA is burned
2. You receive an equivalent amount of STAKED-IOTA
3. Minimum stake: 1 IOTA

### Time-locked staking

IOTA also supports time-locked staking:

1. Burn IOTA to mint LOCKED-IOTA (includes expiry date)
2. LOCKED-IOTA can be staked to create TIME-LOCKED-STAKED-IOTA
3. Must stake from oldest locked IOTA first
4. Cannot unstake before lock expiration

<Warning>
  When unstaking, you cannot unstake fractional amounts. It's recommended to stake whole IOTA amounts to avoid complications.
</Warning>

## Transfers

Use the [Transfer Asset](/api-reference/wallets/transfer-asset) endpoint for IOTA transfers:

* **Native IOTA**: Use `kind: Native`
