Coinbax Send

Terms of Service

Last updated: July 3, 2026

1. Agreement to Terms

By accessing or using Coinbax Send (the "Service"), operated by Coinbax, Inc. ("Company," "we," "us," or "our"), you agree to be bound by these Terms of Service ("Terms"). If you do not agree to these Terms, you may not access or use the Service.

The Service provides a non-custodial software interface that enables users to interact directly with public blockchain networks and smart contracts for the purpose of transferring USDC and USDT stablecoins on the Base network with smart-contract escrow protection.

PLEASE READ THESE TERMS CAREFULLY. SECTION 13 CONTAINS A BINDING ARBITRATION PROVISION AND A WAIVER OF CLASS ACTIONS AND JURY TRIALS, WHICH AFFECT YOUR LEGAL RIGHTS. YOU MAY OPT OUT OF ARBITRATION WITHIN 30 DAYS AS DESCRIBED IN SECTION 13.

2. Eligibility

You must meet the following requirements to use the Service:

  • Be at least 18 years of age
  • Have the legal capacity to enter into a binding agreement
  • Not be a resident of, or located in, any jurisdiction where use of the Service would be prohibited
  • Not be subject to economic sanctions or designated on any prohibited party list
  • Own or have authorized access to a compatible self-custodial wallet

3. Non-Custodial Nature of Service

Important: Coinbax Send is a non-custodial service. This means:

  • We never take possession, custody, or control of your digital assets
  • All transactions are signed and executed on-chain by you through your own self-custodial wallet
  • While a transfer is in its hold window, the funds are held by an on-chain escrow smart contract — not by us; we hold no key that can take custody of or redirect them
  • You are solely responsible for the security of your wallet and private keys
  • We do not store, have access to, or manage your private keys or seed phrases
  • Once an escrow is released to the recipient or refunded to you, the transaction is final — neither we nor anyone else can reverse it, and we cannot move, redirect, or recover funds

4. Escrow Service

Every transfer made through the Service is held in an escrow smart contract on the Base network for a hold window you select (from 5 minutes up to 7 days). During the hold window:

  • You (the sender) may cancel the transfer; on cancellation the principal is returned to your wallet and the service fee is retained
  • You may release the funds to the recipient early at any time
  • After the window passes, the escrow contract permits release to the recipient automatically
  • Where SMS verification is enabled, a one-time code must be verified before release

Multi-recipient (batch) transfers enter escrow atomically — either every payment in the batch is created or none are. After creation, each escrow in the batch is independent and may be cancelled or released individually, subject to the same hold window.

These rights are enforced by the escrow smart contract itself. We do not have the ability to release, cancel, or redirect an escrow on your behalf.

5. Service Fees

Before you sign any transaction, the Service displays a complete quote showing the amount, the service fee, and the exact total that will leave your wallet. By signing, you accept the quoted fee. If you cancel an escrow during its hold window, the principal is returned to your wallet and the service fee is retained.

The service fee is inclusive of the blockchain network fees (gas) required to process your transaction; you are not charged separately for gas. The quoted fee, shown and accepted before you sign, is the only charge for using the Service.

6. User Responsibilities

By using the Service, you agree to:

  • Provide accurate information when required
  • Verify the accuracy of recipient wallet addresses before initiating transfers, and monitor your escrows during their hold windows
  • Maintain the security and confidentiality of your wallet credentials
  • Comply with all applicable laws and regulations in your jurisdiction
  • Not use the Service for any illegal or unauthorized purpose
  • Not attempt to interfere with or disrupt the Service or its infrastructure

7. Prohibited Activities

You may not use the Service to:

  • Engage in money laundering, terrorist financing, or other financial crimes
  • Violate any applicable sanctions laws or regulations
  • Transfer funds to or from sanctioned individuals, entities, or jurisdictions
  • Circumvent any security measures, compliance controls, or access controls
  • Engage in fraudulent or deceptive activities
  • Violate the intellectual property rights of others

8. Suspension and Termination

We may suspend or terminate your access to the Service, or decline to process a transaction, at any time and without prior notice if we reasonably believe you have violated these Terms, applicable law, or our Sanctions & Compliance Policy, or where we are required to do so by law.

Because the Service is non-custodial, suspension or termination affects your access to our interface only. It does not — and cannot — affect assets held in your wallet, and any escrow already created remains governed by the escrow smart contract, including your on-chain cancellation and release rights.

9. Risks and Disclaimers

You acknowledge and accept the following risks:

  • Volatility Risk: Digital assets, including stablecoins, can lose value, including through loss of their intended peg.
  • Technology Risk: Blockchain technology and smart contracts may contain bugs or vulnerabilities.
  • Finality: Once an escrow is released or refunded, the transaction is final and cannot be reversed.
  • User Error: The escrow hold window reduces, but does not eliminate, the risk of loss from sending to an incorrect address. If you do not cancel before the window passes, funds release to the address you entered.
  • Regulatory Risk: Laws and regulations regarding digital assets may change.

10. Limitation of Liability

TO THE MAXIMUM EXTENT PERMITTED BY LAW, THE COMPANY SHALL NOT BE LIABLE FOR ANY INDIRECT, INCIDENTAL, SPECIAL, CONSEQUENTIAL, OR PUNITIVE DAMAGES, OR ANY LOSS OF PROFITS OR REVENUES, WHETHER INCURRED DIRECTLY OR INDIRECTLY, OR ANY LOSS OF DATA, USE, GOODWILL, OR OTHER INTANGIBLE LOSSES RESULTING FROM:

  • Your use or inability to use the Service
  • Any unauthorized access to or use of our servers
  • Any errors, bugs, or vulnerabilities in the Service or underlying blockchain networks
  • Any third-party conduct or content

11. Indemnification

You agree to indemnify, defend, and hold harmless the Company and its officers, directors, employees, and agents from and against any claims, liabilities, damages, losses, and expenses arising out of or in any way connected with your use of the Service or violation of these Terms.

12. Modifications to Terms

We reserve the right to modify these Terms at any time. We will notify users of material changes by updating the "Last Updated" date and, where appropriate, providing additional notice. Your continued use of the Service after such modifications constitutes acceptance of the updated Terms.

13. Dispute Resolution and Arbitration

PLEASE READ THIS SECTION CAREFULLY. IT REQUIRES THAT DISPUTES BE RESOLVED THROUGH BINDING INDIVIDUAL ARBITRATION AND WAIVES YOUR RIGHT TO A JURY TRIAL AND TO PARTICIPATE IN CLASS ACTIONS. YOU MAY OPT OUT AS DESCRIBED BELOW.

  • Informal Resolution First: Before commencing arbitration, you and the Company agree to attempt to resolve any dispute informally. Either party may begin this process by sending a written notice describing the dispute and the requested relief to legal@coinbax.com (or, from us, to the email address associated with your account or a notice through the Service). The parties will negotiate in good faith for at least thirty (30) days from the notice. Neither party may commence arbitration before completing this process. Applicable statutes of limitations are tolled during it.
  • Binding Arbitration: Any dispute arising out of or relating to these Terms or the Service that is not resolved informally shall be resolved by final and binding arbitration administered by the American Arbitration Association (AAA) under its Consumer Arbitration Rules. The Federal Arbitration Act governs the interpretation and enforcement of this Section. The arbitrator — not a court — will decide all issues, including the scope and enforceability of this arbitration agreement. Arbitration will be conducted in English and may proceed by videoconference or document submission; any in-person hearing will take place in the county where you reside. Payment of filing, administration, and arbitrator fees is governed by the AAA rules.
  • Exceptions: Either party may (i) bring an individual claim in small claims court if it qualifies, and (ii) seek injunctive or other equitable relief in a court of competent jurisdiction to address actual or threatened infringement of intellectual property or unauthorized access to or abuse of the Service.
  • Class Action and Jury Waiver: You and the Company each waive the right to a jury trial and agree that disputes will be resolved only on an individual basis — not as a plaintiff or class member in any purported class, consolidated, or representative proceeding. The arbitrator may not consolidate claims of more than one person. If this waiver is found unenforceable as to a particular dispute, this entire arbitration provision shall be void as to that dispute.
  • Mass Filings: If twenty-five (25) or more arbitration demands raising similar claims are filed against the Company by the same or coordinated counsel, the parties agree the demands will be resolved in staged proceedings under the AAA’s mass-arbitration procedures: a set of bellwether cases will proceed first, and remaining demands will be held in abeyance (with limitation periods tolled) pending their resolution and a subsequent good-faith global mediation.
  • Opt-Out: You may opt out of this arbitration agreement (including the class action waiver, but not the jury waiver applicable to court proceedings) by emailing legal@coinbax.com within thirty (30) days of first accepting these Terms, stating your name, the wallet address you use with the Service, and your intent to opt out. Opting out does not affect any other provision of these Terms.

14. Governing Law and Venue

These Terms shall be governed by and construed in accordance with the laws of the State of Delaware, United States, without regard to its conflict of law provisions.

Any dispute that is not subject to arbitration under Section 13 — including disputes brought under its exceptions or where you have validly opted out — shall be brought exclusively in the state or federal courts located in the State of Delaware, and each party consents to the personal jurisdiction of, and venue in, those courts.

15. General Provisions

  • Severability: If any provision of these Terms is held invalid or unenforceable, that provision will be enforced to the maximum extent permissible and the remaining provisions will remain in full force and effect.
  • Entire Agreement: These Terms, together with the Privacy Policy and the Sanctions & Compliance Policy, constitute the entire agreement between you and the Company regarding the Service and supersede any prior agreements on that subject.
  • No Waiver: Our failure to enforce any right or provision of these Terms is not a waiver of that right or provision.
  • Assignment: You may not assign or transfer these Terms without our prior written consent. We may assign these Terms in connection with a merger, acquisition, or sale of assets.
  • Survival: Provisions that by their nature should survive termination — including Risks and Disclaimers, Limitation of Liability, Indemnification, Dispute Resolution and Arbitration, and Governing Law and Venue — survive any termination of these Terms.
