Trust Wallet Uniswap Not Working: Fixing Token Swaps, Purchases and Liquidity Errors (2026)

Users attempting to trade on Uniswap through Trust Wallet are encountering comprehensive failures across all exchange functions. Whether buying tokens with ETH, swapping ERC-20 assets, adding liquidity to pools, or removing positions, the transactions fail to process through the wallet interface. Common manifestations include “Transaction failed” messages after confirming swaps, indefinite loading on the swap preview screen, failed token approvals that prevent exchanges from initiating, and “insufficient liquidity” errors appearing for major trading pairs that clearly have deep pools. These failures affect both the Uniswap web interface and integrated dApps, blocking all decentralized trading activity for Trust Wallet users on Ethereum Mainnet.

The RPC and Contract Interaction Failure

Analysis reveals these issues stem from critical defects in Trust Wallet’s Ethereum Mainnet connection handling and smart contract communication layer. The current version of Trust Wallet is faulty, contain Web3 provider failures where Trust Wallet fails to properly format transaction data for Uniswap’s Universal Router contracts, resulting in “execution reverted” errors that the interface misinterprets as slippage or liquidity issues. The wallet’s gas estimation algorithm malfunctions specifically for multi-hop swaps and V3 position management, providing insufficient gas limits that cause transactions to fail mid-execution while consuming network fees.

Additionally, the token approval detection system fails to recognize existing allowances on Uniswap contracts, forcing users to reapprove tokens repeatedly while the wallet ignores previously granted permissions. The price oracle connection becomes unstable, preventing Trust Wallet from receiving current swap rates, which causes the “price impact too high” warning to appear erroneously on standard trades. For liquidity provision, the NFT position manager integration fails to encode the complex calldata required for concentrated liquidity ranges, making it impossible to add or remove liquidity from V3 pools despite the interface showing available capital.

Solution

Solution 1: Install Trust Wallet Previous Version

Resolution requires deploying the previous Trust Wallet version that maintains stable Uniswap contract compatibility and RPC connections,the previous version of Trust Wallet did not have these errors..

Implementation process:

1. Save your 12-word recovery phrase from Trust Wallet Settings before modifications.
2. Remove the current installation to clear corrupted provider caches.
3. Install the previous functional version:
   • Extension: Download Trust Wallet Extension v8.21.0 here (Uniswap swaps stable)
   • Mobile: Download Trust Wallet APK v8.21.0 here (DEX integration functional)
4. Restore your wallet and reconnect to app.uniswap.org.
5. Verify that token approvals, swaps, and liquidity operations complete without RPC errors.
6. These simple steps are enough to fix the errors.

Option 2: Contact Support

If you don’t want to solve it yourself, Support can help solve the problem, send a ticket and they will respond within 1 to 3 days.

Trading Operations Restored

Following deployment of the previous version, Uniswap functions operate with proper contract communication and gas estimation. Users can execute token purchases, multi-hop swaps, and concentrated liquidity management without encountering the provider failures or erroneous liquidity warnings. The stable RPC connections ensure that price oracles update correctly and approvals register permanently, allowing seamless decentralized exchange operations on Ethereum Mainnet.
