Outcome-oriented execution

Intent-Based DeFi Execution

An intent describes the outcome a user authorizes instead of asking them to manually orchestrate each intermediate DeFi step. DZap's Fuse integration model separates intent authorization from settlement, with solver participation and explicit execution conditions.

What is a DeFi intent?

A transaction request typically prescribes specific calls. An intent instead expresses constraints around an authorized outcome, such as delivering an asset to a recipient on a destination chain. An executor or solver may choose how to fulfill those constraints.

This does not remove blockchain risk. The trust model depends on the intent format, on-chain verification, solver design, failure handling and refund or expiry semantics.

The lifecycle developers should understand

The application obtains a supported intent quote, reviews its route and fees, constructs the authorization payload, asks the user to inspect the terms and sign, then monitors the solver or execution layer for final status.

Bind the source token, amount, destination, recipient and slippage constraints.
Include fee, deadline and route conditions as required by the current contract/API schema.
Verify the exact signing payload and approval model before presenting it to the wallet.
Differentiate signed intent, submitted transaction and completed destination settlement.
Handle expiry, cancellation and failed fulfillment according to the specified route.

Comparing direct execution and solver settlement

Direct routing can offer applications more explicit control over each selected route and transaction payload. Intent-based execution can simplify the user-facing experience when the chosen product supports solver settlement and the associated guarantees.

The correct choice depends on destination coverage, custody requirements, user consent, settlement model and the recoverability of a failed route.

Operational and security considerations

A solver-based system should be evaluated for replay protection, signature domain separation, deadline enforcement, expected-output constraints, liquidity availability and fallback paths. Integrators should consult current deployed contracts and audits.

Avoid treating a gasless quote, single signature, or estimated settlement time as a universal property of every DZap route.

Frequently asked questions

Does an intent always mean one signature?

Signature and approval requirements depend on wallet state, chain, token and route capabilities. Use the current Fuse documentation rather than assuming every action fits one signature.

Who settles an intent?

The Fuse model involves executors or solvers according to the currently documented architecture. Their responsibilities and applicable trust conditions should be reviewed for the actual route.

Are intents the same as guaranteed execution?

No. Execution can depend on expiry, available liquidity, settlement conditions and solver participation. Surface the outcome and failure model to users.
