Free TON DeFi (Ethereum)

Free TON DeFi (Ethereum)

@favoritefx

Hello!

We are more than happy to present you with the first DeFi prototype with primitive mechanics.

With it, you can transfer liquidity from ETH to TON, send swapped tokens to other addresses, withdraw it back to the ETH.

We have published all the solutions in the open-source and invite you to test it, contribute and help us develop.

🎁 We have also prepared modest rewards for testers: you will receive 1 TON for each swap.


⚠️ Disclaimer

We are not responsible for the performance of the prototype and the safety of funds. Everything can break at any time.

We will be grateful for any feedback and description of the problems.


Solution structure

1) Ethereum

The contract at first requests from the user some tokens so the contract can transfer them itself. After that, the user provides a FreeTON address to receive TON tokens and lock tokens on the contract. To reveal the locked tokens, the user should have the withdraw receipt (list of details: token, amount, receiver, receipt ID) signed by the owner key. The contract checks the signature, all the details, and then transfers tokens.

2) FreeTON

To say simple, the entire contract is a massive map in a format token ID -> user address -> balance, which it stores all users' balances for all token IDs. The contract mints new tokens when the user locks his ETH tokens.

3) The Wallet

To make testing more comfortable, we have added tokens support to the Crystal Wallet available for all major platforms.
