How to Automate Gasless Stablecoin Swaps with B3OS and Relay

Managing stablecoin liquidity often involves repetitive manual swaps that incur unnecessary overhead. By integrating Relay’s gasless swap capabilities into B3OS, teams can now automate these token-to-token exchanges as part of larger onchain workflows. This guide explores how to leverage B3OS templates to build efficient, gas-minimized swap operations without writing custom smart contracts.

What you will learn

• Relay enables gasless stablecoin-to-stablecoin swaps within the B3OS platform.
• B3OS templates drastically reduce the time required to build and deploy complex swap workflows.
• Workflows can be triggered automatically based on specific onchain events or manually on demand.
• Slack notifications can be integrated into the workflow to track execution status in real-time.
• B3OS provides a visual, node-based interface that removes the need for custom code when managing DeFi operations.

The Efficiency of Gasless Swaps

Stablecoin-to-stablecoin swaps are a core requirement for many DeFi operators, yet they often suffer from the friction of gas management. By utilizing Relay within the B3OS ecosystem, users can execute these swaps without the typical gas overhead, effectively streamlining the movement of assets between stable pairs.

This integration allows builders to treat swaps as modular components of a larger workflow, rather than isolated manual tasks.

Building with B3OS Templates

B3OS simplifies the creation of these workflows through pre-configured templates. By selecting the token-to-token swap template, the platform automatically generates the necessary nodes to handle the transaction logic.

Users only need to specify their connected wallet, the input and output tokens, and the desired swap amount. B3OS handles the underlying orchestration, ensuring that the workflow structure is ready for deployment on mainnet.

Configuring Workflow Execution

Once the swap parameters are defined, B3OS allows for granular control over how the workflow is triggered. You can set these swaps to run on demand or link them to specific onchain triggers, such as a smart contract event or a balance threshold.

The node-based interface provides clear visibility into each step of the process, ensuring that the swap executes exactly as intended.

Monitoring and Notifications

Transparency is vital for onchain operations. B3OS allows you to integrate notification services like Slack directly into your workflow. With every execution, the system can push updates to your preferred channel, providing a real-time audit trail of every swap performed.

This visibility ensures that operators are always informed of their wallet activity without needing to manually check block explorers.

Workflow ideas to try in B3OS

• Automated Stablecoin RebalancingAutomatically swap excess stablecoin holdings into a preferred asset when a wallet balance exceeds a defined threshold.
• Gasless Treasury ManagementExecute routine stablecoin swaps for operational expenses without requiring gas tokens in the source wallet.
• Event-Driven Liquidity ProvisioningTrigger a swap into a specific stablecoin immediately following a smart contract event, ensuring liquidity is ready for the next phase of a workflow.

Frequently asked questions

Do I need to write code to use these swap workflows?

No, B3OS uses a no-code, node-based interface to build and manage these workflows.

Are all stablecoin swaps gasless?

The gasless feature is powered by Relay and is specifically optimized for stablecoin-to-stablecoin pairs.

Can I trigger these workflows automatically?

Yes, B3OS workflows can be configured to run on demand or triggered by specific onchain events.
