To choose a Blackhole swap type, match your token pair to a pool, then compare the quote before trading. Stable pools suit tokens meant to hold similar prices; classic pools suit pairs whose prices move apart; concentrated pools can improve a quote near the current price. You need an Avalanche wallet and some AVAX for network fees.
What happens when you swap on Blackhole?
A decentralized exchange (DEX) uses code on Avalanche to trade tokens from shared supplies called liquidity pools. You add the token you are selling to a pool and receive the token you are buying. The amount you receive depends on the pool’s balance and the size of your trade.
A Blackhole swap can use one pool or a route through two. For example, a trade from USDC to a newer token might pass through AVAX if that route gives more output. Each pool on the route may charge a fee, so compare the final amount you would receive.
Genesis Pools help projects build liquidity before a new token launches; they are not another swap type. veBLACK comes from locking BLACK to vote on rewards for pools. You do not need veBLACK to trade.
Which pool type suits your trade?
Blackhole has three main pool types, each suited to a different price pattern. The live quote still decides how many tokens your trade would receive.
- Stablecoin pool: Best for pairs such as USDC/USDT, where both tokens aim to stay near $1. It does not fit AVAX/USDC or a stablecoin that has lost its dollar peg.
- Classic pool: Best for pairs whose prices can move far apart, such as AVAX/BLACK. It works across the full price range, but may give less output than a concentrated pool with more tokens near today’s price.
- Concentrated liquidity pool: Best when traders have placed tokens near the current price, which can improve the quote. Those tokens are available only within a chosen price range. A large trade, or a price outside that range, may get a worse quote.
For a Blackhole token swap, identify the token you hold, the token you want, and the amount. The Blackhole swap platform lets you exchange one supported token for another. Check its quoted output for your amount before you ask your wallet to confirm the trade.
How do you check and finish the trade?
Use a wallet set to Avalanche’s C-Chain, such as Core, and keep some AVAX for gas, the network charge. Both tokens must be on that chain. A token held on another network cannot be spent in this trade.
For example, suppose 100 USDC is quoted at 99.70 USDT. The difference can reflect pool fees and price impact: your trade changes the pool’s price. With an illustrative 0.5% slippage tolerance, the lowest acceptable output is about 99.20 USDT. Slippage is an extra price change while the transaction waits; below that minimum, the swap fails.
Check the expected output, minimum output, pool fees, and estimated AVAX gas. Pool fees depend on the pools used; gas changes with network demand. If this is your first trade with that token, your wallet may ask for an approval transaction before the swap transaction. Approval lets the exchange code spend the amount you permit.
Before confirming, check the token’s contract address against its official source; tokens can share a name or symbol. Read the spending approval and wallet confirmation, then check the completed transaction and your new balance. A failed transaction can still use AVAX gas.
