암호화폐 용어집
암호화폐를 스왑할 때 마주치는 주요 용어를 쉬운 말로 설명합니다.
- Non-custodial
- A service that never holds your funds or private keys. Swaps move wallet-to-wallet; you stay in control the whole time.
- Refund address
- A wallet on the origin network where your funds return if a swap can’t complete. Required for cross-chain swaps.
- Deposit address
- The one-time address a route gives you to send your asset to. Sending the exact quoted amount starts the swap.
- TRC20
- A token standard on the Tron network. USDT TRC20 is Tether USD issued on Tron — cheap and fast to transfer.
- ERC20
- The token standard on Ethereum (and EVM chains). USDT/USDC ERC20 are those tokens issued on Ethereum.
- Destination tag / memo
- An extra identifier some networks (XRP, Stellar, TON) use to credit a deposit to the right account on a shared address.
- Slippage
- The difference between the quoted price and the executed price. A slippage tolerance sets how much movement you’ll accept.
- Bridge
- Moving an asset from one network to another — e.g. USDC from Base to Solana. A cross-chain swap of the same asset.
- Gas
- The network fee paid to process a transaction. On Ethereum it’s called gas; other networks have their own fees.
- Stablecoin
- A token designed to track a stable value, usually 1 US dollar — e.g. USDC, USDT, DAI.
- Wrapped token
- A token that represents another asset on a different network — e.g. WBTC represents BTC on Ethereum.
- Confirmation
- A block that includes your transaction. Some networks (like Bitcoin) need several confirmations before funds are final.
- Route
- A specific origin-asset → destination-asset path across networks, with its own quote, fee and availability.
- Quote
- The estimated output, exchange rate and fee for a swap, shown before you deposit. Quotes expire after a short time.
