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?​

The deployment owner — typically Inductiv on behalf of the customer. Pairs are explicitly allowlisted via setPairSupport().

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 — @inductiv/evix-sdk (built on viem)
  • Rust — evix-sdk (built on alloy)

Do I need a wallet client for simulation?​

No. simulateSwap() only requires a PublicClient. The WalletClient is only needed for swap() (execution).

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 via setPairSupport(). 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.
