LE7EL token smart contracts

token/EESeedToken.sol

ERC-20 token with custom ERC-1404 implementation to limit transfers to whitelisted contract address, which will be used for the future conversion to Greet ecosystem token (EE).

Swap.sol

Mints ERC-20 seed tokens for payment token contribution (USDC) by a fixed exchange rate. All contributed tokens go straight to LE7EL DAO multisig.

Uses whitelisting businesses logic for participation, inspired by Gnosis Auction code and the following article.

token/L7LToken.sol

Modern ERC-20 token with permit feature to save gas costs on swaps, the token code is kept lean to reduce potential attack exposure. The maximum supply is limited to 1b tokens, token owner can mint new tokens until the maximum supply is reached. MultiMinter.sol is intended to be the owner of this contract.

MultiMinter.sol

Transient contract which supports management of token minters. LE7EL DAO is supposed to be an ultimate owner of this contract. Minting rights would be given to LE7EL DAO address, swap contract for investors to exchange their seed tokens vesting/RedeemSeedByMint.sol, reward pools for contributors, creators and operators. This contract is upgradable through transferOwnership.

vesting/RedeemSeedByMint.sol

Redeem seed tokens to L7L according to the vesting schedule.

Vesting distribution

Virtual Distributor can be used to distribute vested amounts to investors.

Local installation

Expects Ganache or similar Ethereum client on 127.0.0.1:8545, default network_id is 5777.

npm install
npm run migrate:dev

Testing

Signatures for whitelisting can be generated with the following cli command: truffle exec tasks/generate_signatures.js --network=develop --file_with_address="../your_address_inputs.txt"

your_address_inputs.txt contains coma separated whitelisted wallet. Can be generated with Greet P2P KYC tool.

Default KYC signer wallet used for tests is 0x4253e41227F7af597176963A4F1e8399539e60D5, it's derived from nerve panda scare join quantum reform ski umbrella clap worth barely ask test mnemonic. Don't use it for anything other than local tests, it's insecure.

tasks/generate_signatures.js you can replace test mnemonic with your local Ganache mnemonic, in such case first wallet provider.getAddress(0) will be a whitelisting KYC signer.

You may need to update CLIENT_WHITELIST_SIGNATURE and CLIENT_NO_MONEY_WHITELIST_SIGNATURE in test/seed_token.js and KYC_SIGNER in migrations/2_deploy_seed_token.js for a local signer wallet. Alternatively KYC_SIGNER can be updated on a smart contract level, like: swap.updateContractData.sendTransaction("YOUR_ABI_ENCODED_KYC_SIGNER_WALLET", ether("50000"), ether("150000"), { from: ADMIN }).

To run automatic tests:

npm run test
