BlazeSwap Common Questions

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

The protocol follows the Uniswap v2 architecture, meaning liquidity is pooled in pairs and prices are governed by a constant-product formula. Flare is an EVM-compatible Layer 1 chain featuring native oracle infrastructure, giving BlazeSwap access to on-chain price data that most DEXes must source from external providers. 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 set to 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 Flare's documentation at docs.flare.network. MetaMask users can also use Chainlist to add networks automatically.

Once connected, your address appears in the top-right corner and your balances load into 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 includes native assets like FLR and SGB, wrapped versions (WFLR, WSGB), FAssets such as FXRP and FBTC, and stablecoins including USDT0 and USDT.

You can also add custom tokens by pasting a contract address into the token selector. The interface will alert you if the token is not on the default list — always confirm the contract address from an official source before swapping an unlisted token.

The protocol applies a 0.3% fee on 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 relative to Ethereum mainnet, typically just 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 click 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 that in mind during busy blocks.

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

Go to the Pool section from the top navigation. Click "Add Liquidity," then select the two tokens you wish to deposit. You must supply both tokens 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 portion of fees grows proportionally as volume flows through. When you want 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.

Be aware of impermanent loss: if the price ratio between your two tokens shifts significantly while you are providing liquidity, you may end up with less dollar value than if you had simply held them. 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 launched in April 2025.

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

To claim, navigate to the Rewards tab. Connect your wallet and any claimable balance will appear. 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 has 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 without risk. Bugs can persist 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 if a contract exploit were to occur, recovery would not be guaranteed.

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

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

Token approvals can also cause 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 skipped, the swap itself will revert. Check your wallet's transaction history to confirm the approval completed successfully.

Sometimes 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 are experiencing congested blocks.

FLR is the native gas token of the Flare network, much like 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 fully responsive and works 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 like 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 allow assets from non-smart-contract chains — Bitcoin (as FBTC), XRP (as FXRP), and others — to be brought onto Flare in a trust-minimized way using collateral and agent infrastructure rather than a centralized custodian.

Because 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 bootstrap liquidity in FAsset pools, making it practical to swap between, say, FXRP and USDT without leaving the chain. You can mint FAssets through 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 out per token in.

BlazeSwap displays a price impact percentage beneath the swap fields. Green indicates low impact (under 1%). Yellow signals caution (1–5%). Red means your trade will significantly move the market and you are likely leaving value behind compared to splitting it into smaller trades. If you see a red warning, consider breaking the swap into smaller portions or finding a pool with greater liquidity.

BlazeSwap was among the first DEXes live on Flare mainnet and has built up substantial liquidity depth in core pairs since its launch. The rewards programs — rFLR, FAssets incentives, USDT0 — have attracted trading volume and LP participation that newer or less established protocols lack.

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 based 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 usability available today.
