PayPlic - A Crypto2Crypto Gateway

Inspiration

Crypto to Crypto Gateway is a bridge between two blockchains. For an instance, a USDT holder in Ethereum can purchase tokens from the XDC Ecosystem.

What it does

• Crypto to Crypto Gateway is a bridge between two blockchains. For an instance, a USDT holder in Ethereum can purchase tokens from the XDC Ecosystem.
• Token founders, can sign-up with their ERC20 wallet and get an API Key.
• Using this API Key, they can enable crypto payment in USDT / USDC / DAI and they can decide which token to pair with
• Deposit their funds in the XRC20 Gateway contract
• User should be able to purchase using the stablecoins and get the relevant XDC Token

How we built it

• ERC20 Gateway Solidity Contract
• XRC20 Gateway Solidity Contract
• Plugin Decentralized Oracle for bridge
• External Adapter to pull the pricing of XDC EcoSystem from the external world

Challenges we ran into

• ## Accomplishments that we're proud of
• Bridge has been enabled between the blockchains.
• This can be taken to any EVM-compatible blockchains.

What we learned

• Integration of two different blockchains.
• How to bridge using the event mechanism
