System Overview

Coffhee's bond marketplace is a decentralized credit infrastructure designed to bridge traditional fixed-income instruments with on-chain liquidity using Fully Homomorphic Encryption (FHE).

                        STATUS: Operational

                        KERNEL: Powered By- Fhenix v0.7.1

                        ARCH: Multi-Layer Bond Architecture, Automated Marketmaker

                        CHAIN: Arbitrum, Robinhood Chain

ERC-3475: The Multi-Token Standard

Unlike standard tokens, ERC-3475 allows for complex debt structures. Every bond is defined by a Class and a Nonce.

Class: Defines the bond issuer and series.
Nonce: Defines specific maturity dates and coupon cycles.

FHENIX Integration

Standard blockchains are transparent. To protect institutional trade secrets and individual net worth, we've integrated Fhenix.

The Encryption Workflow

By utilizing Fhenix's fhe.sol contract, we enable ERC 1155 tokens are listed and used to hold the bond tokens.:

                        1. Input: ERC 1155 balance is encrypted.

                        2. Process: Only the token owner can decrypt.

                        3. Result: Confidential information will remain private.

This ensures that bond holdings, volume, and transaction history remain mathematically private while staying verifiable on the public ledger.

Security Protocols

Access control is maintained via Signed Re-encryption Requests. Only the legitimate owner of a wallet can generate the EIP-712 signature required to view their private bond balance.

$ decrypt --asset bond_01 --auth eip712_sig
