BlazeSwap Common Questions

BlazeSwap is a decentralized exchange (DEX) built on the Flare and Songbird networks. It allows you to swap tokens, contribute liquidity, and earn rewards — all without surrendering custody of your assets to any third party.

The protocol follows the Uniswap v2 architecture, meaning liquidity is pooled in pairs and prices are determined by a constant-product formula. Flare is an EVM-compatible Layer 1 chain featuring native oracle infrastructure, granting BlazeSwap access to on-chain price data that most DEXes must obtain from external sources. Songbird serves as Flare's canary network, running alongside it.

Both networks are accessible through the same interface. You select your active network within your wallet before connecting.

Click "Connect wallet" on the main swap screen. A modal will appear listing supported providers — MetaMask, WalletConnect-compatible wallets, and others. Choose yours and approve the connection request inside your wallet app.

Before connecting, ensure your wallet is configured for either the Flare (chain ID 14) or Songbird (chain ID 19) network. If neither appears in your wallet's network list, you can add them manually through the Flare documentation at docs.flare.network. MetaMask users may also use Chainlist to add networks automatically.

Once connected, your address appears in the top-right corner and balances populate the swap interface.

Any ERC-20 token deployed on Flare or Songbird can be swapped, provided a liquidity pool exists for that pair. The default token list covers native assets like FLR and SGB, wrapped versions (WFLR, WSGB), FAssets such as FXRP and FBTC, and stablecoins including USDT0 and USDT.

You may also add custom tokens by pasting a contract address into the token selector. The interface will alert you if the token is absent from the default list — always confirm the contract address from an official source before swapping an unlisted token.

The protocol applies a 0.3% fee to every swap. That fee goes entirely to liquidity providers in the relevant pool — BlazeSwap itself does not collect a protocol cut at this time.

In addition to the 0.3% swap fee, you pay standard Flare or Songbird gas fees in FLR or SGB respectively. Gas on both networks is inexpensive compared to Ethereum mainnet, typically fractions of a cent for a routine swap. Larger or more complex transactions may cost slightly more.

Slippage is the gap between the quoted price when you submit a transaction and the price that actually executes on-chain. Because block time elapses between your action and execution, pool ratios can shift.

The default tolerance is 0.5%. If a swap would execute at a price more than 0.5% worse than quoted, the transaction reverts. For stable pairs with deep liquidity you can reduce this to 0.1%. For volatile or low-liquidity pairs, setting 1–2% helps avoid failed transactions without sacrificing much value. Anything above 5% raises the risk of front-running — keep this in mind on busy blocks.

You can adjust slippage through the settings cog in the swap card header.

Navigate to the Pool section from the top navigation. Click "Add Liquidity," then select the two tokens you wish to deposit. Both tokens must be supplied at the current pool ratio — if a pool does not yet exist, you set the initial price yourself.

After confirming, you receive LP tokens representing your share of the pool. These tokens accumulate the 0.3% fee from every swap in that pair. Your share of fees grows proportionally with trading volume. When you wish to exit, return to Pool, locate your position, and click "Remove Liquidity." The protocol burns your LP tokens and returns the underlying assets along with accumulated fees.

Bear in mind impermanent loss: if the price ratio between your two tokens shifts considerably while you are providing liquidity, you may end up with less dollar value than if you had simply held. This is a known characteristic of AMM-based liquidity provision and is not unique to BlazeSwap.

BlazeSwap has run several incentive programs throughout its history. The rFLR emissions program launched in October 2024 on Flare, distributing rFLR tokens to liquidity providers in eligible pools. FAssets incentives for Songbird began in December 2024, covering pools with assets like FXRP. FXRP incentives followed in October 2025, and USDT0 incentives commenced in April 2025.

Note that the final rFLR distribution took place on 29 March 2026 — consult the latest news panel on the main app for currently active programs.

To claim, go to the Rewards tab. Connect your wallet, and any claimable balance will be displayed. Press "Claim" and confirm in your wallet. Rewards are sent directly to your address.

The core swap contracts of BlazeSwap are derived from the Uniswap v2 codebase, which has undergone multiple audits and been battle-tested across billions of dollars in volume since 2020. Modifications specific to Flare and Songbird have been reviewed internally by the BlazeSwap team.

That said, no smart contract is entirely risk-free. Bugs can exist in audited code, and new attack vectors emerge over time. The protocol is non-custodial — your funds remain in the contracts or your wallet at all times — but recovery cannot be guaranteed in the event of a contract exploit.

Practical steps: use only the official app at the BlazeSwap interface, verify contract addresses before approving tokens, and never share your seed phrase.

The most frequent cause is slippage. The price moved beyond your tolerance between submission and execution. Try increasing slippage slightly and resubmitting. Another common cause is insufficient gas — though gas on Flare is inexpensive, your FLR balance must cover it. If your FLR is nearly depleted, top it up before retrying.

Token approvals can also create confusion. The first time you swap a token, you must send an approval transaction granting the router contract permission to spend it. If that approval transaction failed or was not sent, the swap itself will revert. Check your wallet's transaction history to confirm the approval completed successfully.

Occasionally a transaction deadline expires. The default deadline is 20 minutes from submission — if your transaction remained pending beyond that window, it reverts. Adjust deadline settings in the swap settings panel if you encounter congested blocks.

FLR is the native gas token of the Flare network, similar to how ETH is native on Ethereum. Smart contracts on EVM chains cannot hold or transfer native tokens using the standard ERC-20 interface.

WFLR is "Wrapped FLR" — an ERC-20 contract that holds FLR and issues an equivalent amount of WFLR in return. One WFLR is always redeemable for one FLR. The BlazeSwap router wraps and unwraps FLR automatically when you trade a FLR pair, so most users never need to wrap manually. If you require WFLR directly in your wallet, you can call the deposit function on the WFLR contract or use a dedicated wrap page.

Yes. The BlazeSwap interface is responsive and functions in mobile browsers. The simplest approach is to use a wallet with a built-in browser — MetaMask Mobile, Trust Wallet, and most WalletConnect-compatible apps include one. Open the app URL inside that browser and the wallet connects automatically.

Using a standard mobile browser such as Safari or Chrome and connecting via WalletConnect QR code also works, though the process involves a few additional steps.

FAssets are a bridging mechanism built into Flare's protocol layer. They enable assets from non-smart-contract chains — Bitcoin (as FBTC), XRP (as FXRP), and others — to be brought onto Flare in a trust-minimized manner using collateral and agent infrastructure rather than a centralized custodian.

Since they are native ERC-20 tokens on Flare, FAssets trade on BlazeSwap exactly like any other token. The BlazeSwap team has introduced dedicated incentive programs to build liquidity in FAsset pools, making it practical to swap between, for example, FXRP and USDT without leaving the chain. You can mint FAssets via the FAssets minting interface linked from the banner on the main app.

Price impact measures how much your trade shifts the pool's price. A small trade in a deep pool has near-zero impact. A large trade relative to pool size alters the ratio and you receive fewer tokens per token spent.

BlazeSwap displays a price impact percentage beneath the swap fields. Green indicates low impact (under 1%). Yellow is a caution (1–5%). Red means your trade will substantially move the market and you are likely leaving value on the table compared to a smaller split trade. If you see a red warning, consider dividing the swap into smaller portions or seeking a pool with greater liquidity.

BlazeSwap was among the first DEXes live on Flare mainnet and has built substantial liquidity depth in core pairs since launch. The rewards programs — rFLR, FAssets incentives, USDT0 — have attracted trading volume and LP participation that newer or less established protocols cannot match.

The interface is clean and straightforward. There is no sign-up, no KYC, and no intermediary — just your wallet and the contracts. Fees at 0.3% are standard for an AMM. And because the protocol is open-source and founded on audited Uniswap v2 contracts, its behavior is predictable and well-understood. For most traders on Flare, BlazeSwap delivers the best combination of liquidity, transparency, and ease of use available today.
