If you're experiencing issues with swapping on a third-party DEX, we recommend contacting their support team directly.
A swap fail can occur due to:
Insufficient native token balance
Similar to most blockchains, the Ethereum, Polygon, and Solana blockchain transactions require a transaction fee paid using its native token - ETH, MATIC, or SOL.
We recommend that you always keep a minimum of each primary token ETH, MATIC, and SOL in your wallet for transaction fees.
Network congestion
Network congestion can lead to swap failures, and unfortunately, this is beyond our control. On EVM chains, transaction fees tend to increase significantly during congestion. It is advisable to wait for some time and attempt the swap again later.
Liquidity Provider
In some instances, a swap may fail due to the recommended provider. In this scenario, you can select the provider option and then change the provider to another one on the list.
For EVM chains, we use 0x aggregator to fetch the best possible rates across multiple decentralized exchanges.
Slippage
Solana: Currently, Phantom has a default slippage setting of 0.5% for Solana transactions. This means that if the price of the swap differs by more than 0.5% from the presented price, the swap will fail to prevent you from losing value.
EVM: The swap will fail if the slippage range exceeds the quoted price you agreed upon when initiating the swap. You can retry the swap after some time or enter a higher value of slippage manually (coming soon).
