Customer Terms for Wallets and Digital Asset Applications

By Hank FasthoffSeptember 18, 2026

A customer approves an application’s access to 10,000 USDC, expecting to make a single payment of 100 USDC. The application can, under the permission granted, initiate additional transfers within the approved amount. If your marketing says customers approve every payment separately, a dispute can involve the permission screen, the customer terms, and the conduct of the application.

For a business developing a wallet or digital asset application, drafting customer terms begins with those operational facts. Your lawyers need to understand the service your business supplies, the authority customers grant, and the promises customers encounter before they accept the agreement. Copying another wallet’s terms can import assumptions about control and recovery that your product doesn’t share.

Define the Service and the Contracting Parties

A wallet application may provide software for customers to authorize transactions, maintain accounts through a separate custody provider, or combine several services in one interface. Those arrangements involve different obligations. You should identify the legal entity supplying each service and explain which agreement governs the customer’s relationship with that entity.

A purchase button illustrates the distinction. If a separate provider sells the asset and conducts identity checks, your terms should describe that provider’s role and the point at which the customer accepts its agreement. If your business also promises to transmit instructions or assist with a failed purchase, those commitments belong in your agreement. Identifying another provider doesn’t explain what your business has agreed to do.

The description should cover the product customers can use today. Planned recovery features, proposed network support, and services awaiting provider approval shouldn’t appear as available benefits. A feature with separate eligibility requirements should have those conditions presented where customers encounter the offer.

Describe Control and Recovery Precisely

A private key is information used to authorize transactions from a blockchain account. Some products leave the customer with exclusive signing authority, while others distribute signing or recovery functions among the customer, the operator, and additional providers. The drafting inquiry concerns who can authorize a transfer, replace a signer, or restore access under the particular arrangement.

“Noncustodial” alone doesn’t explain those functions. You should establish whether your business can initiate transactions under an existing permission, pause a feature, change a recovery process, or approve a replacement device. Any description of customer control should account for those powers and their limits.

Recovery also requires a distinction between access to the application and access to assets. Resetting a password may restore an account screen without restoring a lost signing credential. If your business offers recovery assistance, the terms should describe the conditions, verification steps, and limits of that assistance, including what happens if a participating provider is unavailable. A promise to restore access should correspond to a process your business can perform.

Separate Contract Acceptance From Transaction Permissions

MetaMask’s documentation distinguishes connecting a wallet from granting a token approval. Connection permits an application to request actions; a token approval can authorize a smart contract, meaning a program operating on a blockchain, to use a specified token within an approved quantity. The customer’s permission therefore depends on the request and any authority already granted.

MetaMask’s advanced permissions documentation explains that basic token approvals can authorize more spending than a customer intends, continue without automatic expiration, and depend on manual revocation. It also describes permissions under ERC-7715, a specification for applications to request authority subject to defined conditions. Supporting applications can offer spending limits, recurring allowances, and expiration dates. Those permissions can authorize subsequent transactions without a fresh signature each time, so the terms should describe the authority granted through the product’s particular permission model.

You should explain the scope of any continuing authority, its expiration, and the available cancellation procedure. The interface should distinguish accepting customer terms from authorizing a transaction or granting continuing access to tokens. If both occur during registration, the records should identify each action and the information presented with it.

Establish and Document Agreement

Federal law recognizes electronic contracting. Under 15 U.S.C. § 7001(a), a contract involving interstate or foreign commerce cannot be denied legal effect solely because it is electronic or an electronic signature was used in its formation. Subsection (b) preserves other legal requirements governing the parties’ rights and obligations, so electronic form alone doesn’t establish acceptance of your terms.

Texas law addresses both consent to electronic transactions and attribution of signatures. Business and Commerce Code § 322.005 applies the Texas Uniform Electronic Transactions Act to transactions between parties who have agreed to transact electronically. Under § 322.009, an electronic signature is attributable to a person if it was that person’s act, and effective security procedures can establish attribution. Context and surrounding circumstances determine its legal effect.

In Aerotek, Inc. v. Boyd, the Supreme Court of Texas held in 2021 that the employer conclusively established employees’ electronic signatures on arbitration agreements. The system used login credentials unknown to the employer and recorded each signature with a unique identifier, document type, and timestamp. Applicants could not finish without signing, and the employer could not alter submitted applications. The employees acknowledged completing the process but denied signing the arbitration agreements, offering no other evidence supporting those denials. Although the case concerned employment agreements, it illustrates how authentication procedures, records, and testimony can establish electronic acceptance.

For your application, you should present the terms through a conspicuous link beside an affirmative acceptance action and preserve the accepted version. Useful records include the acceptance language, the screen displayed, the date and time, and the account or wallet identifier associated with the action. A wallet signature used to sign in requires separate analysis of what the message said and whether the customer intended to accept the agreement.

Explain Fees and Unsuccessful Transactions

Customers may pay an application fee, a provider fee, and a network charge in the same operation. Your terms should distinguish those charges, identify how they are calculated, and explain when they become payable. Where the interface displays an estimate, it should identify what can change before execution and how the customer authorizes that change.

An unsuccessful transaction can incur a network charge, depending on when it fails. Ethereum’s gas documentation explains that gas measures computational effort. A transaction rejected during validation before inclusion in a block consumes no gas, while a transaction that exhausts its gas during execution consumes the gas supplied even though its changes are reversed. A promise of “no charge if the transaction fails” should specify whether your business refunds its service fee, reimburses a network charge, or offers both.

A conversion feature also calls for terms about the quoted amount and its duration. You should establish what happens when a quote expires, a provider rejects the instruction, or the customer receives less than the displayed estimate under an authorized price tolerance. The refund and complaint procedures should identify which business handles each charge.

Address Suspension and the End of Service

Suspending access to an application can have consequences different from freezing assets. Depending on the design, a customer may retain the ability to transact through other software, or may depend on a provider to authorize a withdrawal. Your suspension terms should reflect the particular arrangement and distinguish restrictions your business controls from restrictions imposed by another provider.

You should address the reasons for suspension, any notice or review procedure, and what happens to pending instructions. The terms should also explain how customers obtain available transaction records and whether signing credentials can be exported or access restored elsewhere. Any promise concerning transfers during suspension must account for applicable legal restrictions and the authority your business possesses.

Closure presents a separate problem. If your company discontinues the application, customers will need to know whether continuing access depends on your servers, a provider’s cooperation, or credentials they already possess. The agreement should describe the assistance your business undertakes to provide and any advance notice it promises, without guaranteeing cooperation that another company hasn’t agreed to supply.

Allocate Liability Within Applicable Law

Liability provisions should address the losses the service can cause and the obligations your business has assumed. A cap based on subscription fees may have a different commercial effect from a cap covering assets affected by an error. Exclusions for lost profits, failed networks, or customer mistakes also require analysis of how those events relate to the company’s conduct and applicable law.

Texas consumer law limits contractual waivers. For claims within the Texas Deceptive Trade Practices Act, Business and Commerce Code § 17.42 makes a consumer’s waiver void unless statutory conditions are satisfied. Those conditions include a signed writing, the absence of a significantly disparate bargaining position, representation by legal counsel, and prescribed presentation and wording. The defendant cannot select or suggest that counsel, and a waiver doesn’t provide a defense to an attorney general enforcement action under § 17.47.

An arbitration provision requires decisions about the disputes covered, the administrator, the rules, the location, and the allocation of costs. Those choices should correspond to the customers and jurisdictions your business serves. A provision copied from another application may impose procedures your business hasn’t evaluated or costs it hasn’t budgeted.

Keep Product Claims and Changes Consistent With the Agreement

Marketing and customer terms should describe the same control, recovery, and payment features. The Federal Trade Commission’s advertising guidance states that fine print cannot contradict an advertisement’s other statements or correct the misleading impression they leave. An assurance that customers have exclusive control therefore warrants examination wherever it appears, including registration screens and support materials.

Adding recurring permissions, changing recovery providers, or introducing an operator fee can alter the service customers accepted. You should assess the required notice and assent before implementing each change, preserve prior versions, and record which terms govern each customer. A revision date on a webpage doesn’t document what an existing customer received or accepted.

Before drafting, you should assemble the registration screens, permission requests, fee displays, provider agreements, and proposed support commitments. Those materials let counsel draft terms around the service customers will receive and identify promises the business must change before launch. The resulting agreement should explain what your company undertakes to do, what authority the customer grants, and how the parties address failure.
