What Should a Cross-Chain Wallet Show Before You Sign?

Learn the route, estimated cost, minimum received, permissions and status details a cross-chain wallet should explain before you sign.

A cross-chain wallet pre-sign checklist showing route, estimated cost, minimum received and permissions.

Cross-chain products are becoming easier to use. That is good progress.

The hard part is deciding what “easier” should mean.

On 19 August 2026, LI.FI introduced Smart Deposit Addresses, a product that can turn a complex onchain action into a simpler Send → Receive flow. A user sends tokens to a unique deposit address, while routing and execution happen in the background. LI.FI lists EVM-to-Solana among the available route types.

The direction makes sense: users should not need to operate every infrastructure component themselves. But simplifying execution should not remove the information needed for informed consent.

A cross-chain wallet still needs to answer one practical question before funds leave the user’s control:

What am I authorising, and what outcome should I reasonably expect?

Simple should not mean silent

Good abstraction removes unnecessary work. It does not hide consequences.

A user may not need to know the internal implementation of every bridge, solver or liquidity source. They still need to know where value is moving, what may change, and what action they are about to approve.

This distinction matters because a cross-chain journey can include more than one decision:

  • an asset may leave one network and arrive on another;
  • a swap or conversion may occur in the route;
  • the amount received may change within defined limits;
  • an approval may grant a contract permission to use a token;
  • execution may pause, fail or require a recovery path;
  • settlement may finish before the user’s real destination action is complete.

The interface does not need to display every protocol detail at once. It does need to make the important consequences inspectable.

1. Source and destination

The first layer should be unambiguous:

  • source network;
  • destination network;
  • asset being sent;
  • asset expected at the destination;
  • recipient or destination account.

These fields create the basic boundary of the transaction. A polished confirmation screen is not useful if the user cannot quickly verify where the asset starts and where it is supposed to arrive.

Chain abstraction may reduce the need to manually switch networks. It should not make the source and destination disappear.

2. The route at the right level of detail

Some users only need a clear summary. Others want to inspect the route.

A useful cross-chain wallet can support both by using progressive disclosure:

  • show the route summary by default;
  • let the user expand the underlying steps;
  • distinguish the quoted plan from the executed result;
  • label third-party infrastructure accurately when it is relevant and verified.

The goal is not to turn every user into a routing engineer. The goal is to avoid a black box at the exact moment the user must decide whether to continue.

3. Total estimated cost

“Fee” is often treated as a single number, but a cross-chain outcome can be affected by several layers.

Depending on the route, the user may need to consider:

  • source-network gas;
  • bridge or routing charges;
  • swap fees;
  • price impact;
  • slippage tolerance;
  • destination-network requirements.

Not every layer applies to every route. That is why the interface should distinguish what is known, what is estimated, and what is not included.

The most useful question is not simply, “What is the fee?” It is:

How much value is expected to leave, and how much is expected to arrive?

4. Expected amount and minimum received

Expected output and minimum received are not the same thing.

The expected amount is a forecast based on the current quote. The minimum received is the lower boundary the user has agreed to accept under the route’s conditions.

Showing only the most optimistic number can create false confidence. A clearer interface places the two values close together and explains why they may differ.

If the product cannot provide a meaningful minimum for a particular route, it should say so rather than invent precision.

5. Permissions and approvals

Self-custody protects the user’s authority over their keys. It does not automatically explain what a transaction permits.

Before the wallet prompt, the interface should make unusual or important permissions easier to inspect. This can include:

  • which token a contract may use;
  • the allowance requested;
  • whether the permission is limited or open-ended;
  • whether the approval is separate from the route execution;
  • which contract is receiving that authority.

A hardware signer can protect the key used to authorise the transaction. It cannot replace a readable explanation of the transaction itself.

6. ETA as an estimate

Cross-chain time is not one number.

There may be quote time, source execution, routing, destination settlement and a final application action. An interface should avoid presenting a route estimate as a guarantee.

Recent Solana changes illustrate why this distinction remains important. Solana’s 24 August 2026 changelog reported that mainnet slot time had moved from 400ms to 350ms, while testnet moved from 250ms to 200ms. Faster slots can improve responsiveness, but they do not explain the full state of a cross-chain route.

A faster network still needs clear product language for:

  • pending;
  • confirmed;
  • failed;
  • last verified checkpoint;
  • next action.

Speed is a protocol property. Clarity is a product responsibility.

7. What simulation can and cannot tell you

Transaction simulation can forecast an expected outcome before a transaction reaches the signer. That can reveal useful information and potential problems.

But a successful simulation is not a safety certificate.

Conditions can change between simulation and execution. A simulation may not capture every external dependency or reflect the user’s actual intent. The interface should present simulation as evidence, not as a guarantee.

The useful pattern is:

  • what the simulation observed;
  • what it expects to happen;
  • what remains uncertain;
  • what the user should verify independently.

8. The destination action

For many users, bridging is not the objective.

They may want to stake, deposit, pay, trade or use an application after the asset reaches the destination network. Settlement is therefore a checkpoint, not always the end of the journey.

A destination-aware interface should explain:

  • what arrives;
  • where it arrives;
  • whether destination gas is needed;
  • what action comes next;
  • what happens if the next action cannot complete.

This is especially important when the route is presented as one simple action. If the interface compresses several steps into one flow, it should preserve the user’s ability to understand the final outcome.

A practical pre-sign checklist

Before confirming a cross-chain transaction, check whether the interface answers these questions:

  1. Which network and asset am I sending from?
  2. Which network, asset and account should receive the result?
  3. What route or sequence is expected?
  4. What is the total estimated cost?
  5. What is the expected amount and minimum received?
  6. What permissions am I granting?
  7. How long is the route estimated to take?
  8. What could remain pending or fail?
  9. What will the interface show after submission?
  10. What action should I take when the route completes?

Not every product needs to show all ten answers at the same visual level. The important point is that the answers remain available before the user signs.

Biti.pro’s design boundary

Biti.pro is being built around clarity before signing for self-custody users moving assets from EVM networks into Solana.

The product direction is to make the route, total estimated fees, minimum received and estimated completion time easier to review before the wallet prompt. Simulation and warnings can add evidence, while the interface should continue to distinguish an expected outcome from a guaranteed one.

Biti.pro is pre-launch. This article describes the product direction and a broader design standard; it is not evidence that every illustrated workflow or state model has shipped.

The principle is simple:

Remove unnecessary work. Keep the consequences readable.
