GasTanker

From wallet address to funded wallet.

GasTanker starts with monitoring. It moves money only after you connect a funding source, allowlist your relay, and turn on a policy that allows it.

  1. 01

    Add your wallets

    Live

    Give GasTanker:

    • the network (for example Base, Solana, or Stellar),
    • the wallet address,
    • a name your team will recognise.

    Monitoring needs no credentials and no exchange connection. Add one wallet or a whole estate; your exchange configuration doesn't change.

  2. 02

    Decide what “healthy” means

    Live

    Set a low-balance threshold and a target balance for each wallet.

    Alert me when this Base wallet drops below 0.01 ETH, and plan a refill to 0.05 ETH.

    Every policy change creates a new revision. You can pause a policy at any time; pausing stops new operations but never hides history.

  3. 03

    Choose where alerts go

    Live

    Send low-balance alerts to the places your team already watches:

    • email,
    • Slack,
    • Discord.

    New channels start inactive. Send a test, then activate them.

    At this point you already have a complete monitoring product.

    Connect your exchange

    Live: funding previewFunding: coming soon

    Create a dedicated exchange API key for GasTanker.

    During the preview, GasTanker only reads with the key. It tests a new key against the exchange you chose before it replaces a working one, and needs only read access. You see your available balances and a dry-run funding plan, but nothing moves.

    When automatic funding is enabled for your organization, you grant only the specific permissions the funding route needs.

    GasTanker never asks for a seed phrase or a wallet private key.

    Allowlist your relay once

    Coming soon

    GasTanker gives your organization a dedicated relay address. Your relay isn't shared with any other customer.

    Add it to your exchange's withdrawal allowlist for each network you enable. For compatible EVM networks it can be the same address.

    From now on, adding or rotating operational wallets happens in GasTanker, not on the exchange.

    Run a funding batch with approval

    Coming soon

    Before turning on automation, approve a funding batch by hand.

    You see:

    • which wallets triggered and why
    • how much each wallet needs
    • the single exchange withdrawal that covers them
    • fees and withdrawal minimums
    • where every unit is allocated
    • what was received and how it was verified
  2. 07

    Turn on bounded automation

    Planned

    Once a route has proved itself, let narrowly bounded, low-risk top-ups run without manual approval. Everything else still waits for a human.

A low balance becomes a controlled funding workflow.

  1. 01

    Detect

    Live

    A wallet falls below its threshold.

  2. 02

    Confirm

    Live

    GasTanker re-reads the balance from an independent source and rejects suspicious or inconsistent readings. A failed read never creates an operation.

  3. 03

    Plan

    Live: dry-run

    Compatible deficits in your organization are grouped into one batch, respecting network, policy, and per-wallet attribution, so small top-ups don't each pay a withdrawal minimum.

  4. 04

    Guard

    Coming soon

    Before anything moves: verified destination, no other operation in flight, spend caps, velocity limits, approval state, route health, and available liquidity.

  5. 05

    Withdraw

    Coming soon

    Your exchange converts what's needed and withdraws it to your organization's relay. This is the only withdrawal destination GasTanker ever uses.

  6. 06

    Allocate

    Coming soon

    The relay forwards each wallet's share, using sponsored execution where supported and bounded native gas otherwise.

  7. 07

    Verify

    Coming soon

    The operation completes only after each destination wallet has received its gas.

  8. 08

    Reconcile

    Coming soon

    Every amount, fee, and remainder is accounted for and saved for your team.

Sometimes the safest action is not to spend.

GasTanker holds a funding operation when:

A delayed wallet is a smaller failure than a duplicate transfer.

  • the amount exceeds a limit,
  • a wallet is being funded too often,
  • the organization has reached its cap,
  • the network or route is paused or unhealthy,
  • the relay or destination cannot be verified,
  • the exchange balance is insufficient,
  • a human approval is pending or was declined,
  • GasTanker cannot tell whether a previous withdrawal or forward already moved funds.

On the last one, GasTanker does not retry. It checks the exchange and the chain first.
