Overview of the 4 main source codes repositories implemented under the M3tering Protocol

M3tering ProtocolGitHub

🤖 M3ter: ERC-721 contract

Deployment Address: 0x39fb420Bd583cCC8Afd1A1eAce2907fe300ABD02

M3ter is an ERC-721 (NFT) contract where each NTF represent a smart metering device registerd on-chain by it's manufacturer. Similar to Helium device NFTs on Solana, or Wicrypt device NFTs on polygon. These devices contain cryptographic secure elements used to sign energy consumption data they measure. the purpose of keyByTokenId is to map an NFT's tokenId to the cryptographic PublicKey for a device (bytes 32 key for ED25519 digital signature scheme), while the tokenIdByKey is used to reverse map the above mentioned PublicKey to the NTF's tokenId

🪙 Solaxy: ERC-20 as ERC-4626 contract

Deployment Address: 0xF4F3c1666E750E014DE65c50d0e98B1263E678B8

Solaxy is an ERC-20 token contract that implements a linear bonding curve with sDAI as the reserve currency. The bonding curve allows users to buy and sell Solaxy tokens directly from/to the contract at a dynamic price determined by the curve's slope.

Solaxy extends its functionality by providing support for ERC-4626; a tokenized vault interface. This interface allows the Solaxy contract to interact with other DeFi protocols and platforms seamlessly. ERC-4626 integration enhances the capabilities of Solaxy in the context of token bonding curves.
