AVNU is a Starknet swap-routing service with recurring buys, paymaster tools and related on-chain features. Its terms identify 419 Dev Labs as the service provider and, as of 15 October 2026, specify a standard 0.10% routing fee. Wallet signing remains with the user, but approvals, protocol contracts, staking and bridge routes create different asset exposures.[3][4]

Additional Information
Sections ↑AVNU’s cost and control model is more specific than a generic free, noncustodial swap label. A user signs the transaction, but the quote may include several fees, and token allowances or optional products can place assets under contract rules. The relevant comparison is the net output after those costs and the permissions granted for the chosen feature.[3][4][5]
