Biconomy alternatives for token buys across networks
For wallets and trading apps weighing Biconomy alternatives, the Unigox Trade API buys a token on another network from one signed stablecoin transfer, with no bridge or companion account. Stay with Biconomy for sponsored gas, agents and conditional orders.
When the Trade API fits better than Biconomy
Your users buy from MetaMask, Rabby or another external wallet
From an external wallet, Biconomy routes the bought token through a temporary account, so your flow adds a withdrawal step or the token stays there. A token without permit support needs an approval transaction instead of a signed message. With the Trade API your user sends one stablecoin transfer, and your calls send the token to the address they already have.
The destination leg should not depend on a bridge
Biconomy routes a cross-chain swap through bridges such as Across and LiFi, combined with DEX swaps. Unigox delivers the stablecoin on the destination network from its own liquidity, then runs your contract calls there in order, in one transaction.
You want one refund rule your support team can explain
Biconomy's docs say cross-chain flows are not atomic, so your app adds cleanup steps that send leftover tokens back. With the Trade API, a buy that cannot complete returns the stablecoin to the receiver's address on the destination network. The refund is in full; if your calls ran and failed, the gas they used is deducted, up to the gas charge shown in the quote.
When to stay with Biconomy
You pay your users' gas
Biconomy sponsors gas from one tank across its networks, with per-transaction and total caps set in its dashboard, and invoices you at the end of the month. Users can also pay gas in USDC, USDT or another token with liquidity. The Trade API quote states the network execution fee (gas) up front and takes it out of the trade itself.
Your product runs on agents or price triggers
Biconomy's Smart Sessions give an AI agent or bot scoped, time-limited, revocable permissions, and its conditional execution holds a transaction until an on-chain condition such as a price is met. A Trade API buy runs when your user signs it.
You need swaps, TWAPs or vault deposits
Biconomy swaps any token for any token across its chains with one signature, runs limit orders and TWAPs, and deposits into lending and yield protocols through DeFi Zaps. A Trade API order only buys; to sell, the user swaps the token on the network where it sits.
You want a key from the dashboard today
Biconomy hands out an API key from its dashboard that works on every network it supports, with public REST and TypeScript SDK docs. Trade API access is requested on its page, and Unigox reviews your assets and networks and agrees terms before your team builds.
Biconomy vs the Unigox Trade API
Both columns describe the same operation: a user holding a stablecoin on one network buys a token on another network.
| Topic | Biconomy | Unigox |
|---|---|---|
| What it is | An orchestration layer: multi-step, multi-chain workflows signed once, with gas abstraction, scheduling, conditional execution and delegated permissions. | An API for one job: your user buys a token on another network with a stablecoin they already hold. Your team picks the assets and builds the screens. |
| What the user signs | One signature from a smart account or an embedded wallet (EIP-7702). From an external wallet: one gasless signed message per funding token, or an approval transaction instead for a token without permit support. | One stablecoin transfer, sent on its own or inside an ERC-4337, Safe, EIP-7702 or MetaMask delegation batch. |
| Where the user's funds go | From an external wallet, tokens pass through a temporary account the user owns, and the flow adds a withdrawal step back to the user's wallet. | The transfer goes to Unigox; the bought token goes to the address your calls choose, such as the user's own address. |
| Reaching the other network | Routed through bridges and DEXs such as Across and LiFi; you can allow or deny specific bridges and DEXs. | Unigox delivers the stablecoin on the destination network from its own liquidity. |
| Calls after delivery | Composable calls where each step can use the exact output of the step before. Same-chain batches are all or nothing; cross-chain flows are not. | Contract calls you build, run in order in one transaction on the destination network. |
| Gas | Paid in USDC, USDT or another token with liquidity, so no native coin is needed. A smart account can pay from any supported chain; an external wallet pays from its funding token on the same network. Or you sponsor it, invoiced monthly. | A network execution fee (gas) stated in the quote before the user signs, taken out of the trade itself. |
| If a buy fails | Cleanup steps you add send leftover tokens back to the user after a failed cross-chain step. | The stablecoin returns to the receiver on the destination network. If the calls ran and failed, the gas used is deducted, capped at the quoted charge. |
| What the user pays with | Any token to any token across its chains, swapped and bridged as needed. | The same stablecoin Unigox delivers on the destination network. |
| Networks | A published list of EVM mainnets, among them Ethereum, Base, Arbitrum, Sonic, Monad and Robinhood Chain. | Networks that support the stablecoin used for the buy, confirmed with you per asset. |
| Tracking | Each run returns a supertransaction hash; an accepted request is not yet complete, so you poll its status or open it in Biconomy's explorer. | Status by source network and transaction hash, with your own order reference bound to the quote. |
| Access and pricing | Self-serve API key from the dashboard. No public price list: each quote returns its fee, and pricing for sponsored gas is set on a call. | Access on request. Commercial terms are agreed on a call, and partners earn a share of trading revenue. |

Build the buy
Your backend requests a quote with the amount, the receiver and your contract calls. Your app shows the price, gas charge and deadline, and the user signs one stablecoin transfer.
Show the result
Your app checks the status and shows the asset received or the refund, and says where a refund arrives. Unigox works with your team on the first purchase.
Questions about Biconomy alternatives
What are the Biconomy alternatives for a wallet that lets users buy tokens?
If your users hold a stablecoin and want a token on another network, the Unigox Trade API does that from one signed transfer, filled from Unigox liquidity. If you need sponsored gas, agents, limit orders or vault deposits, Biconomy covers more of that work.
Which Biconomy competitors avoid bridging on the destination leg?
Unigox is one. Biconomy routes cross-chain swaps through bridges and DEXs it selects. The Trade API delivers the stablecoin on the destination network from Unigox's own liquidity and runs your calls there in one transaction.
Is the Trade API a replacement for Biconomy's smart accounts and paymaster?
No. If you are replacing Biconomy's smart accounts, bundler or gas sponsorship, look at other account-abstraction platforms. The Trade API covers one part of what Biconomy does: buying a token on another network from a stablecoin the user already holds.
Do users still need a withdrawal step when they switch from Biconomy?
No. In Biconomy's mode for external wallets, the bought token sits in a temporary account until a withdrawal instruction sends it back. With the Trade API the user signs one stablecoin transfer, and your calls send the bought token to the address you choose, such as the user's own address.
Do I have to drop Biconomy to use the Trade API?
No. The Trade API is a separate integration with its own access, so you can keep Biconomy for sponsored gas, swaps back and automation, and send cross-network buys to Unigox. Your app decides which service handles each action.
