FAQ

General​

Is Evix a universal public router?​

No. Evix is provisioned per customer and per chain. Each deployment is an independent contract instance with its own configuration, pair allowlist, and execution strategy.

Is every deployment identical?​

No. Deployments may differ in:

  • Supported pairs
  • Execution strategy and optimization profile
  • Gas tuning
  • Chain-specific behavior

Who controls pair configuration?​

Inductiv manages pair configuration. Enabling or disabling a pair requires updates on both the contract and the Evix system. Contact Inductiv to request changes.

Integration​

Can I integrate Evix from Solidity only?​

Yes. The IEvix interface is a single function with six parameters. No SDK required for on-chain integrations.

IEvix(evixAddress).swap(tokenIn, tokenOut, amountIn, deadline, minAmountOut, recipient);

Which SDKs are available?​

  • TypeScript - built on viem (source)
  • Rust - built on alloy (source)

Both are reference implementations - use them as a starting point for your own integration.

Do I need to simulate before executing?​

No. Most integrators set minAmountOut based on their own pricing or oracle data and execute directly. simulateSwap() is available in the SDK if needed, but is not required.

What chains are supported?​

Evix can be deployed on any EVM-compatible chain. Deployments are provisioned per customer - contact Inductiv for your specific chain requirements.

Execution​

What happens if the deadline passes?​

The transaction reverts with DeadlineExceeded(). No tokens are moved, no gas is consumed beyond the failed transaction.

What happens if slippage exceeds my tolerance?​

The transaction reverts with InsufficientOutput(amountOut, minAmountOut). No tokens are moved.

Can I swap any token pair?​

Only pairs that have been explicitly enabled on your deployment. Use getSupportedPairs() to check which pairs are available. Attempting to swap an unsupported pair reverts with UnsupportedPair(tokenIn, tokenOut).

Do I need to approve the Evix contract?​

Yes. The Evix contract uses transferFrom to pull tokenIn from the caller. You must approve the contract to spend your input token before swapping.

Customization​

Is the system customizable?​

Yes. Customization is a core part of the product model. Each deployment can be configured for specific pairs, execution profiles, gas strategies, and chain behavior.

Can I request new pairs?​

Yes. Contact Inductiv to enable additional pairs on your deployment.

Can I have different configurations per chain?​

Yes. Each chain deployment is independent and can be configured differently.
