Terms of service

Last updated 4 November 2026

These terms apply to the GasTanker website and service, provided by Fractional Tech LTD (“GasTanker”, “we”). By using the service, you agree to them on behalf of yourself and the organization you represent.

The beta

GasTanker is in a design-partner beta. Monitoring, gas policies, alerts, the dashboard, and the API are available to invited organizations for wallets on the networks listed on our coverage page. That page, the dashboard, and the API always show the networks the service supports, and we may add or remove networks during the beta. Automatic funding is not yet available, and GasTanker does not move funds for any organization. If we offer it later, it will come with updated terms that we share with you before it starts. Features may change, and we may pause or end the beta.

Your account

  • Keep your sign-in details, second factor, and API keys secure. Actions taken with them are yours.
  • Give accurate information, and tell us promptly if you suspect unauthorized access.
  • You are responsible for the people you invite to your organization and the roles you give them.

Your wallets and funds

You keep control of your wallets, keys, and exchange accounts. GasTanker never asks for seed phrases, recovery phrases, or wallet private keys. During the beta, GasTanker only reads balances and sends alerts; it does not move funds. If you connect a Bybit, Binance, Coinbase, Gate, KuCoin, or OKX account (or more than one), you give GasTanker a dedicated API key for each (for KuCoin and OKX, with the key's passphrase) so it can show what a top-up would need. The key needs only read access. GasTanker accepts a key that can also trade, transfer, or withdraw, but during the beta it only reads with it. You choose the permissions a key has; a key limited to reading limits what anyone holding it can do. GasTanker tests a new key against the exchange you chose before it replaces a connected one.

Alerts and readings depend on blockchain networks, data providers, and messaging services outside our control. They can be delayed, missed, or briefly wrong. When GasTanker cannot read a balance reliably it reports it as unknown rather than guessing. Monitoring helps your team act, but you remain responsible for keeping your wallets funded.

Acceptable use

Do not:

  • use the service for unlawful activity, or to monitor wallets you are not authorized to operate;
  • attempt to access other organizations' data, or probe, overload, or disrupt the service;
  • reverse engineer the service, except where the law allows it;
  • resell the service without our written agreement.

Fees

Beta partners use monitoring at no charge. We will publish pricing before general availability and give beta partners advance notice before any charge starts. Nothing is charged without that notice.

Your data

You own the data you put into GasTanker. You let us use it to provide, secure, and improve the service, as described in our privacy notice.

Our service

We own GasTanker, its software, and its content. Feedback you share may be used to improve the service without obligation to you.

No warranty

The beta is provided “as is” and “as available”. To the extent the law allows, we make no warranties about availability, accuracy, or fitness for a particular purpose.

Limitation of liability

To the extent the law allows, we are not liable for indirect or consequential losses, including lost profits, failed or delayed transactions, or lost data, arising from the beta. Nothing in these terms limits liability that cannot be limited by law.

Ending use

You can stop using GasTanker at any time. We may suspend or end access if you breach these terms, if required by law, or when the beta ends. Sections that by their nature should continue, such as liability limits, continue after access ends.

Governing law

These terms, and any dispute or claim arising out of or in connection with them, are governed by the law of England and Wales. The courts of England and Wales have exclusive jurisdiction.

Changes and contact

We may update these terms and will revise the date above. If a change is material, we will tell beta partners before it takes effect. Questions about these terms go through our contact page.
