Intent-based cryptocurrency trading: How the solver finds better transactions

On-chain Intention Trading: Principles, Advantages and Practical Guide

The trading experience of most on-chain redemption is like booking a ticket in the past: choose the route, pray that the price will remain the same, and if it changes, you have to endure slippage. The intention-based trading model completely changes that. All you have to do is tell the network what you want-not how to do it-and professional solvers will compete to complete the order for you under the best conditions.

This article will deeply analyze how this competitive mechanism can truly achieve better transactions, analyze its application scenarios and limitations, and teach you how to use it safely. We will also focus on the latest data and product releases, including incentive adjustments to the CoW Protocol and NEAR's confidential intent feature open to developers.

Quick overview of core points

What is the intention? A statement of the expected result (such as exchanging token A for token B, setting a minimum received quantity and deadline) that allows the solver to freely choose the execution path.

Why may the price be better? Competitive solvers comprehensively search through DEX, aggregator, off-chain inquiry, and batch matching internal order flows.

Privacy options: Some protocols support confidential execution to avoid exposing paths before transactions and reduce MEV leakage.

Platforms launched: CoW Protocol and UniswapX on EVM;NEAR's confidential intentions are open to developers and available on Aurora Intents.

Main risks: Authorization abuse, centralization of the solver, auction failure/delay, opaque fee sharing.

Best application scenarios: Medium and large conversions, portfolio transactions, or transactions across liquidity paths, where search and batch processing can transcend a single path.

Cost: Gas fee plus protocol fee; some protocols will return excess returns if the solver exceeds your minimum requirements.

The core mechanism of intent trading

With intent, you no longer need to micromanage the transaction path. You just need to specify the outcome you care about-for example, converting 10 ETH into stablecoins and getting at least X USDC before a certain block height-and publish this as an order. Subsequently, a set of third-party solvers competed to execute the order. They can route across multiple DEXs, hedge against other user orders in bulk auctions, or access off-chain market makers. The winning solver proves that your constraints are met and receives a built-in success fee reward.

This market structure is rapidly evolving. On the EVM side, CoW Protocol uses batch auctions and "coincidence of demand" mechanisms to directly match users when possible. A July 2026 preprint analysis of CoW's reward reform (CIP-74) found that the change redistributed transaction value by order size and increased volume-weighted solver concentration (the Herfindahl index rose from 0.176 to 0.241), while no significant changes in average execution quality were detected within a range of approximately 7 basis points. This reminds us to focus on incentive design, but not assume that it will deteriorate transaction quality.

On NEAR, intentions now include a confidentiality switch. As of July 8, 2026, confidential intentions have shifted from limited release to full openness to developers, including a one-click redemption API, which performs routing through confidentiality to ensure that paths are not disclosed before settlement. A few days later, since the confidential route was officially launched on the Aurora Intents Swap API on July 13, 2026, the existing Aurora client only needs to modify one quotation parameter to activate it.

NEAR's public information during the fully open window shows that it has quickly gained market recognition: more than US$1.5 billion has been settled on NEAR Intention, daily confidential TVL exceeds 30 million, and about 42% of near.com intend to switch to confidential mode in the first few weeks. While adopting data may be noisy, the direction is clear: The intention track is going into production and competing on privacy, search quality and speed.

Quick Glossary

Intention: A declarative order that describes the final status you want (tokens, minimum quantity, deadline) rather than the execution path.

Solvers: Searchers or market makers competing for execution intent, usually through auctions, path finding, or internal hedging.

Batch auction: Match multiple orders together within a time window, achieving demand coincidence and reducing slippage.

MEV: Value extracted by reordering, inserting, or reviewing transactions. Intention to reduce leaks by hiding paths or hedging traffic.

Confidential execution: Keep routing details private before settlement, reducing the leakage of pre-transaction information to malicious actors.

Excess return: The extra value captured when the solver performs better than your minimum requirements; depending on the protocol, it may be shared with you.

Step-by-step guide

1. Select the intent track: Start with a wallet or DApp that supports intent, such as CoW Protocol, UniswapX-enabled front-end, or intent apps on NEAR/Aurora.

2. Set clear constraints: defines selling tokens, buying tokens, minimum output volume and reasonable deadline. Tighter minimum requirements reduce risk; slightly longer windows improve matching quality.

3. Select privacy mode: If supported, enable confidential execution to avoid early publishing of routes to the memory pool, which is particularly beneficial for large or sensitive transactions.

4. Review Fees and Excess Policies: Check whether the agreement charges fees, who gets excess benefits when the solver overcompletes, and whether Gas fees are reimbursed or charged separately.

5. Submit and let the solver compete: Don't focus on routes. The focus is on outsourcing search. Focus on final settlement rather than pre-trade quotes.

6. On-chain verification and settlement: After execution of , confirm the amount received, block timestamp and any deductions through the blockchain browser.

7. Track solver quality over time: If your tool exposes a solver ID or receipt, export a transaction record and compare the actual price to the benchmark DEX path.

8. Revoke outdated authorizations: Regularly clean up token authorizations that are no longer needed to reduce the risk of abuse if the front end is compromised.

How the solver finds better prices

The solver is like a travel agent with a back pass. They simultaneously detect multiple paths: splitting orders between DEX pools, cross-hedging buy and sell orders in batches, invoking private inquiry market makers, or submitting them to auctions that liquidate many users at a fairer price. The key is that they can see a more comprehensive picture of your wallet than in a single transaction.

In a batch system, the order flow becomes inventory. If someone wants to switch ETH to USDC and another person wants to switch USDC to ETH, it's a direct match with no pool slip point. If dozens of users are trading similar currency pairs, bulk transactions can be balanced in a way that cannot be achieved by a single user exchange. Add in private quotes or hidden order books, and the solvers begin to present prices that look "unrealistically" better than single path AMM-because they don't go that path.

Motivation is crucial here. If the solver is paid in a way that rewards quality rather than just size, healthy competition usually occurs. When incentives tilt, concentration may increase. We see signs in CoW's CIP-74 analysis, which shows a higher concentration of winners by volume, but the average execution quality has not been significantly affected. This in itself doesn't matter whether it's good or bad, but it's an indicator that savvy users and DAOs should focus on.

Choose between CoW, UniswapX, and NEAR

You don't need to bind a single track. Choose based on your asset pair, chain, and privacy or speed priorities.

CoW Protocol (EVM): Batch auction, demand coincidental hedging. Disclosure by default and relying on bulk hedging to reduce leaks. Registered solvers compete in auctions. Suitable for medium and large transactions, multi-user batches, and stable currency pairs.

UniswapX (EVM): Off-chain Dutch-style auction, with fillers issuing bids. Routing details are not broadcast in the memory pool. The filler/solver competes to take orders. Suitable for popular currency pairs, Gas efficient transactions, AMM + inquiry mix.

NEAR Confidential Intention: Intention to perform collateral secret routing. Developers can use confidential execution when fully open it. Builder/router plus integrated mobility source. Suitable for users who prioritize privacy and path protection.

Aurora Intents (NEAR EVM)：The intent on Aurora comes with a confidential switch. Confidential routing can be enabled through a single quote parameter. Suitable for existing Aurora integrators and EVM users seeking privacy protection with minimal changes on NEAR.

On NEAR, the confidentiality feature is noteworthy because it has now become mainstream: it will be fully open on July 8, 2026, providing a one-click redemption API, and the Aurora Intention Swap API will be launched on July 13, 2026, allowing existing clients to only change one parameter. Early adoption data in NEAR's public information shows significant usage gained within weeks.

Professional tip: If you can tolerate slightly longer batch windows, you can extend the deadline and tighten the minimum output. You can often get a better match without having to chase a fast and leaky path.

Delay, scale and liquidity scenarios

Intention shines when search space and hedging can play a practical role. If you exchange a few hundred dollars on a highly liquid currency pair, the gain may be negligible compared to a direct AMM transaction. But once you get into four or five digits-especially on pairs where liquidity is spread across multiple venues-solver competition becomes crucial.

Delay is another dimension. Batch auctions may require short windows to collect traffic and clear it. This delay helps with optimization, but is not suitable for time-sensitive hedging. Dutch-style auction-style fillers can be faster while still protecting your path from being compromised. Confidential enforcement helps prevent others from prejudging your ideas, but it is not a panacea: If the market fluctuates, your minimum requirements protect you, not the track brand.

There is also cross-liquidity logic. The solver may split orders, obtain stablecoins across multiple pools, or route them through baskets. This is something your wallet should not do manually. Give the system a clear goal and let it work.

Traps and warning signals

Excessive token authorizations: grants only the required permissions and periodically revokes old authorizations. If the front end is breached, the unlimited amount will bring a heavy blow.

Fees and excess income share are opaque: Understand who gets the extra income when your trade exceeds the minimum requirement. Some agreements will be returned, some will not.

Solver centralization: Incentive adjustments may lead to concentration of winners. Recent CoW data shows that volume-weighted concentration has increased after CIP-74. Fewer winners mean elastic risk.

Timeouts and failed auctions: Uncleared lots or expired quotes may prevent you from closing the deal. Set realistic deadlines and monitor status.

Fishing "intent" pop-up: Treat unfamiliar signatures like any authorization. If you don't recognize the domain name or contract, please suspend the operation.

Misunderstanding that privacy is invisible: Confidential enforcement reduces routing leaks but does not reduce market risk. Your minimum output is still your line of defense.

FAQs

Are intent-based transactions cheaper than using DEX directly? Sometimes. If the solver can net your orders in batches or get better quotes from different venues, you will earn more excess returns than if you could redeem through a single route. For extremely small, ultra-liquid transactions, the difference may be negligible. Always compare actual transaction prices rather than quotes.

Will I lose control of assets with intent? No. You still sign and set constraints from your wallet. The solver proposes an execution plan that meets these conditions; it will be settled only if it matches what you approved.

How can confidentiality help my transactions? By hiding routing details before settlement, confidential execution reduces pre-transaction information leakage, thereby reducing the possibility of incurring MEV tactics. NEAR's confidential intentions are now fully open to developers and available on Aurora Intention, and privacy is becoming a standard switch rather than a niche feature.

What is the difference between intent and ordinary aggregators? The aggregator still calculates the path and broadcasts it. Intention outsources decisions to a solver market, which can net multiple users and access private liquidity. The result is that your orders face more competition-often resulting in better actual transaction prices.

Will solver excitation damage the quality of my execution? They affect who wins. Recent CoW Protocol analysis showed that changes in rewards resulted in increased concentration of top solvers, but no deterioration in average execution quality was detected within the sample window. This is an issue that requires monitoring, not a reason for panic.

Is this financial advice? No. Markets fluctuate, contracts may have loopholes, and agreements change quickly. Please start with a small amount, set strict minimum requirements, and verify what you sign.
