Turnkey releases Transaction Management with Gas Sponsorship

Today, Turnkey is expanding its wallet infrastructure with new Transaction Management and Gas Sponsorship capabilities for web3 transaction workflows.

Executing transactions onchain can be hard. Teams need to coordinate transaction construction, nonce sequencing, gas estimation + payment, signing, broadcast, and status tracking  across chains.

All of this complexity slows development, increases failure rates, and creates operational risk.

Teams shouldn’t have to build and maintain this execution layer themselves, or depend on a patchwork of vendors. That's why we built this new infrastructure to accelerate product development and increase transaction success rates.

Introducing Turnkey’s Transaction Management

Turnkey’s Transaction Management provides a single, consistent execution layer for sending blockchain transactions across EVM chains.

It manages the full transaction lifecycle end-to-end: 

• Construction: Assembling the transaction details such as recipient, amount, data, and parameters.
• Nonce sequencing: Assigning the correct transaction order number to prevent conflicts or replay issues.
• Gas estimation and payment: Calculating required network fees and ensure sufficient funds to cover execution costs.
• Signing: Authorizing the transaction using the private key or secure signing system.
• Broadcast: Submitting the signed transaction to the blockchain network for validation and inclusion.
• Status tracking: Monitoring confirmations, failures, or final settlement after submission.

Our Transaction Management infrastructure works with existing wallets, contracts, and security policies. No relayers, bundlers, or chain-specific infrastructure to run. You send a transaction. Turnkey handles everything required to execute it reliably.

Right now, it’s live on EIP-7702–compatible chains, including: Ethereum, Base and Polygon with more chains coming soon.

What Transaction Management makes possible for teams

Developers who have built transaction infrastructure from scratch know the headaches: stuck transactions, nonce collisions, failed retries, customers confused by transaction/gas fees, and hours spent debugging why something worked on testnet but broke in production. 

Multiply that across chains and environments, and suddenly you’re maintaining status tracking pipelines instead of shipping features.

Turnkey’s Transaction Management handles all of this for you.

Reliable at scale — Transactions are executed consistently across chains and environments. 

No more plumbing — Custom retry logic, nonce sequencing, and status tracking are all handled.

Built for reliability — Proper transaction construction and sequencing reduce failed transactions that can disrupt operations, impact revenue, or degrade user trust.

Safer by default — Policy enforcement and signing are centralized, reducing surface area for errors and exploits.

Ship faster — Your team focuses on product, not transaction infrastructure.

One of the most impactful capabilities this unlocks is Gas Sponsorship, which removes a major source of friction for end users.

Gas Sponsorship: Remove the biggest onboarding barrier

Gas is the fee paid to blockchain validators to process and record a transaction. It compensates the network for computation, storage, and security when transacting onchain, and it often creates unnecessary friction. 

Users have to think about fees before they can complete even simple actions, which adds extra steps, uncertainty around costs, and occasional failed transactions when fees aren’t handled correctly.

Gas sponsorship removes that complexity by letting you cover fees directly, so users can transact without worrying about the mechanics behind the transaction. Built directly on Turnkey Transaction Management, Gas Sponsorship lets you cover transaction fees for your users with a single API flag. 

Why Gas Sponsorship matters

Here is what Gas Sponsorship unlocks for your team:

Instant onboarding Users go from signup to first transaction without needing to acquire native tokens first. 

Transparent, predictable costs You pay only for gas consumed, charged at cost, and at up to 75% cheaper than alternatives.

No new infrastructure Forget relayers, bundlers, custom infra, or third parties. Gas Sponsorship is built into Turnkey's transaction layer, so there's nothing new to deploy, manage, or debug.

Seamless integration Works with your existing wallets, contracts, and policies. No rearchitecting required.

Whether you're onboarding your first users or scaling to millions, Gas Sponsorship keeps the experience clean without adding complexity to your stack.

Getting Started with Turnkey’s Transaction Management

Implementing Turnkey’s Transaction Management infrastructure takes a single API call. You can start with transaction execution and enable Gas Sponsorship with a flag if it makes sense for your use case. No separate integration required.

Full documentation and implementation guides are available in our transaction management and gas sponsorship docs. If you want help choosing the right setup for your product or have questions about custom deployment options, reach out to our team. We'll walk you through exactly what you need.

Transaction infrastructure shouldn't slow you down. Start building today.
