Intents

An intent is a signed message that says "this is what I want" without specifying how to make it happen. Pondora's dex is built around them.

The shift

Most dexes - on Cardano and elsewhere - work imperatively: you submit a transaction that performs a specific swap on a specific pool at a specific moment. If that path doesn't exist, the trade fails. If the pool moves before your tx confirms, you eat slippage.

An intent flips this around. You sign:

• what you have (e.g., 1,000 ADA),
• what you want (e.g., at least 480 USDM), and
• when it expires.

You don't specify the route, the pool, the venue, or the order of operations. The matcher figures that out, and the on-chain validator only accepts a transaction that satisfies the conditions you signed.

Why this matters

• Better prices. The matcher can search across every venue - Sailfish, AMM pools, external dexes - and pick the best execution per intent. You don't have to know in advance where the liquidity is.
• No locked funds. Until the moment of settlement, your assets stay in your Smart Account. The intent is a promise, not a deposit.
• Composability. A pending intent can be referenced by other Pondora actions (multi-leg routes, cross-protocol flows) without first being executed and unwound.
• Replay-safe. Every intent carries a unique nonce, validity window, and signature; settlement is atomic per intent.

What "satisfy the intent" means

The on-chain validator checks two things on settlement:

1. You signed the intent - verified via your Smart Account's account key.
2. The result honors what you signed - you got at least your minimum amount out, before the expiry.

It doesn't care which dex gave you the price, how many hops the matcher used, or whether the trade was matched off-chain or on-chain. As long as the math works and the signature is valid, the swap settles.

Where this leads

The next three sections walk through how the intent model reshapes each classical exchange primitive:

• Order Book - limit orders without locked funds.
• AMM - swap against pools without giving up custody.
• The DeFi Kernel - one intent, every venue, structurally better than peer-to-peer order book models.
