Zapper.fi is a DeFi tool that enables users by batching or "zapping" transactions in a batch to simplify their entry and exit into DeFi products and offerings. It is planned to simplify this process and accelerate it. In some situations, this transaction method will minimize investors' gas fees. Users can exchange different assets bi-directionally into pooled interest-bearing tokens using the yZap feature. The goal of yZap is to encourage a more seamless and frictionless swap between different coins. Curve.finance pools can be zapped into the following assets: DAI, USDC, USDT, TUSD, BUSD. To obtain stablecoins in exchange, users can zap out of curve.finance tokens. yZap also allows for bi-directional ETH and DAI swaps
