Trading FAQ

What is slippage?

Slippage is the difference between the price you see when you initiate a swap and the price you actually receive when the transaction executes onchain. Because DEX prices can change during the brief block confirmation window, your final exchange rate may differ slightly from the quoted rate. On Byreal, you can set a slippage tolerance, which is the maximum deviation you're willing to accept. If the price moves beyond that threshold, the transaction automatically reverts to protect you from an unfavourable fill.

Setting slippage too low may cause your transaction to fail in fast-moving markets. Setting it too high increases the risk of receiving a worse rate. A tolerance of 0.5–1% works well for most pairs; use 1–3% for volatile or low-liquidity tokens.

What is price impact?

Price impact measures how much your trade moves the pool's price. When you swap a large amount, especially in a pool with low liquidity, your trade consumes a significant portion of the available reserves, leading to a less favourable rate. Deeper liquidity pools absorb large trades more easily, resulting in lower price impact. Byreal displays the estimated price impact in the swap interface before you confirm your trade. To minimise price impact on large orders, consider splitting them into smaller swaps.

Why did my transaction fail?

Common reasons for failed transactions on Solana include:

• Your slippage tolerance was set too low and the price moved beyond it during confirmation.

• You don't have enough SOL to cover network fees (minimum ~0.01 SOL for swaps).

• The Solana network is congested.

• The token's liquidity changed between when you initiated the swap and when it reached the chain.

If a transaction fails, you still pay a small Solana network fee, but your swap tokens are not deducted.

What does "Not Enough SOL" mean?

Swapping on Byreal requires at least 0.01 SOL in your wallet, and adding liquidity requires 0.02 SOL. These amounts cover Solana network fees and the one-time account rent required by the Solana blockchain when creating new token accounts or LP position accounts. This is a Solana infrastructure requirement, not a Byreal charge.

What tokens can I trade on Byreal?

Byreal supports all tokens that follow the Solana SPL token standard. You can search for tokens by name, ticker symbol, or contract (mint) address directly in the swap interface. Byreal's routing aggregates liquidity from its own pools plus external sources like Raydium, Orca, and Meteora, giving you access to a wide range of tokens including long-tail assets.

How are Solana gas fees calculated?

Solana gas fees (also called network fees) are paid in SOL to validate and process your transaction on the blockchain. They are extremely low compared to Ethereum — typically between 0.00001 and 0.00002 SOL per transaction. In periods of high network activity, an optional priority fee can be added to increase the likelihood of faster confirmation.

What is impermanent loss?

Impermanent loss (IL) occurs when the price ratio of the tokens you deposited into a liquidity pool changes relative to when you first provided liquidity. The larger the price divergence, the greater the potential IL — even if you are earning trading fees. IL is most significant with volatile token pairs, and much less of a concern for stable or highly correlated pairs (for example, USDC/USDT or bbSOL/SOL). IL only becomes realised when you withdraw your liquidity; if the price returns to its original ratio, the loss disappears. A more detailed explanation is available in the Providing Liquidity section.
