3Route Review: Are Its Tezos Swaps and API Worth Using?

3Route has two related products. Its Tezos swap app connects a wallet and combines liquidity from multiple Tezos DEXs, so you can compare routes and make a token swap through one interface. The site advertises support for more than 190 Tezos tokens and over 1,000 liquidity pools, and says a route can combine multiple swaps in one transaction. Those figures are project claims, not a guarantee that every token has deep liquidity or a favorable price at the moment you trade.

The separate API is aimed at apps, traders and AI agents. It returns quotes and can prepare ready-to-sign swap transactions. The API page lists Ethereum, Monad, Robinhood Chain, Base and Etherlink as supported trading chains. Tezos is promoted as the swap app’s core network. The site also lists several payment options for API requests, but payment networks such as Solana and Tempo should not be mistaken for supported swap chains.

The API price is $0.001 per quote or swap request, with no subscription or API key. 3Route accepts API payments through x402 or MPP; the site lists x402 on Base, Solana and Etherlink, and MPP on Tempo. It also mentions batch settlement and sessions for frequent requests. Confirm the payment method and total payment cost for your setup, since a payment on a blockchain can itself involve network fees.

For the Tezos swap interface, 3Route advertises a 0% service fee. That does not make a swap cost-free: Tezos network fees and the pricing and liquidity of the DEX pools used by a route still affect what you receive. The site’s claim of up to 25% better execution is not a promised saving for every trade. Compare the quoted output with alternatives, account for slippage, and check the final transaction before signing. Fees and price impact can change with market conditions.

3Route says it is built by Baking Bad and advertises an audit by Inference. However, the audit report and its scope are not published on the site, so you cannot use that claim alone to determine which contracts, versions or risks were assessed. The project’s public listing shows no audits, making it especially important to ask for the report before treating the audit claim as assurance. The site also does not publish a licence for the service.

The API builds unsigned transactions, and its examples describe signing locally; the Tezos app asks you to connect a wallet. That points to a flow where you authorize the transaction, rather than handing 3Route your wallet keys. Still, check the destination, token amounts and permissions in your wallet. Do not give a service or AI agent your seed phrase or private key. A ready-to-sign transaction can still be harmful if its details are wrong or the route has changed.

For a Tezos token swap, open the 3Route app, connect a compatible Tezos wallet, choose the tokens and enter the amount. Review the route and quoted output, then check the transaction details in your wallet before signing. 3Route says it processes new blocks as they arrive and gives an average quote response time of about 300 milliseconds, but quote speed does not guarantee that the transaction will execute at that price.

For API use, request a quote first, then ask for an unsigned transaction if the route and expected output look acceptable. The API is designed to work without a subscription or API key, with each request paid through x402 or MPP. Developers should verify the chain, token contract, amount and recipient in the returned transaction and test their integration with small amounts before relying on it. Keep signing under your control, especially when an agent prepares transactions automatically.

3Route’s strongest evidence is its specific product and pricing information, but important risk details remain incomplete. The site does not publish the audit report or its scope, a service licence, or detailed conditions for the API’s payment methods. It also does not promise that its route will beat every other aggregator or that a token will have enough liquidity for a large order. Quotes can become stale as pool prices and available liquidity move.

The product is split between a Tezos wallet app and a multichain API, so check which chain you are using instead of assuming every listed payment network supports swaps. The site does not publish a full chain-by-chain breakdown of the API’s token coverage or execution conditions. If you need a documented audit, clear legal terms for every region, or guaranteed fees and execution, ask 3Route for those details or choose a service that publishes them. Never sign a transaction you cannot independently understand.
