Terms of Service

Last updated: June 12, 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.

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, returning the full escrowed amount to your wallet
  • 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 full escrowed amount is returned to your wallet.

You are responsible for blockchain network fees (gas) required to process your transactions on the Base network. Network fees are paid to the network, not to us, and are not refundable.

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. 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.

9. 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

10. 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.

11. 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.

12. Governing Law

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.
