Executive Summary

Utila now supports sponsored transfers on EVM chains, allowing organizations to move stablecoins out of deposit wallets without ever sending native tokens to those wallets. A designated sponsor wallet pays the gas fee on behalf of the source wallet, removing the multi-step funding process that slows down deposit sweeps and payment collection flows.

The feature handles delegation, token approvals, and fee sponsorship in a single transaction initiated from the Utila console or mobile app. For operations teams running deposit-and-sweep architectures, particularly in payments, this removes the manual gas distribution step entirely.

Gas Distribution as Operational Drag

On account-based EVM blockchains, every token transfer requires gas paid in the chain's native currency. For a wallet holding only stablecoins, that means someone has to send native tokens to it before it can send anything out. While gas requirements can be manageable in a single-wallet treasury setup, they become a larger operational burden in a deposit-and-sweep architecture. 

Payment companies and financial operators often create wallets on a per-transaction or per-customer basis, meaning every new deposit address has to receive stablecoins, hold enough native tokens to pay gas, and then sweep funds to an omnibus or treasury wallet.

That gas step adds cost, latency, and operational overhead. Teams either pre-fund deposit wallets with native tokens, tying up capital across potentially thousands of addresses, or trigger a separate funding transaction before each sweep, adding another on-chain step to a simple funds movement. Both approaches require constant balance tracking across active deposit wallets and increase the risk of failed sweeps when an address runs dry.

This creates friction across the organization. Treasury loses capital efficiency, operations manage an additional transaction layer, and engineers have to build gas distribution logic that exists only to work around a blockchain-level constraint.

The Solution: Sponsor-Paid Sweeps with No Native Funding Required

Utila already supports Sponsored Transfers to remove gas-fee friction from stablecoin operations. This new capability extends that model to EVM-based deposit-and-sweep workflows, allowing teams to move stablecoins out of deposit wallets without funding each wallet with native tokens.

EVM Sponsored Transfers decouple gas payment from the wallet initiating the transfer. When moving stablecoins out of a deposit wallet, the operator selects a separate sponsor wallet to cover the gas fee. The deposit wallet never needs to hold native tokens.

The mechanism works through a delegation transaction, an off-chain signature that authorizes a Utila smart contract to execute the transfer on behalf of the source wallet. This delegation happens once per wallet (the first time that wallet is swept using a sponsored transfer) and is embedded directly into the transaction flow. After the initial delegation, subsequent sponsored transfers from the same wallet proceed without repeating the step.

From the operator's perspective, the workflow can be summarized as follows:

1. Select the source wallet holding stablecoins

2. Choose the destination (an omnibus wallet, a treasury address, or any other Utila wallet)

3. Pick a sponsor wallet to cover gas, and confirm the transfer. 

Fee controls are available at each step: operators can set gas to low, medium, high, or a custom value. The platform handles delegation, any required token approvals, and the sponsored transfer itself, surfacing all related transactions for review without requiring the operator to manage them individually.

The Utila console also shows the full context of the transfer: source, destination, sponsor, AML screening status, and related on-chain signatures. For teams that need to audit what happened, every component transaction is visible under the transfer record. For teams that do not need that detail, the experience is a single confirmation screen.

How Teams Benefit

EVM Sponsored Transfers are built for organizations running stablecoin deposit collection, payment processing, or any workflow where wallets receive tokens and need to forward them onward without maintaining native gas reserves.

• No native token distribution to deposit wallets. Sweep stablecoins directly from deposit addresses without pre-funding each wallet with ETH or other native tokens. The sponsor wallet covers gas, keeping deposit wallets single-asset.

• Single-action sweeps from the console and mobile app. Initiate a sponsored transfer from the web console or the Utila mobile app (version 2.11 or later). The delegation, approval, and transfer execute as one flow, with signing handled through the mobile app.

• Any Utila wallet can act as gas sponsor. There is no requirement for a dedicated gas station wallet. Any wallet in the vault with a native token balance can sponsor a transfer, giving operations teams flexibility in how they organize gas coverage.

• Full visibility into related transactions. Each sponsored transfer records the delegation signature, token approval (if applicable), and the transfer itself as linked transactions. Operations and compliance teams can review the full chain of events; teams that do not need the detail can ignore it.

• AML screening and policy enforcement apply as normal. Sponsored transfers pass through the same AML screening, signing policies, and approval flows as any other Utila transaction. Sponsorship does not create a separate execution path or bypass governance controls.

Start Using EVM Sponsored Transfers

EVM Sponsored Transfers are available now in the Utila web console and mobile app. To use sponsored transfers, ensure the Utila mobile app is updated to version 2.11 or later.
