Usage Guide

Floating Point Protocol enables privacy-preserving payments on Ethereum using zero-knowledge proofs and ring signatures. Each Floating Point (FP) represents $10 USDT of value, 100% backed by USDT reserves.

Quick Summary

Buy FP

Pay USDT → Get FP Tokens

10 USDT = 1 FP

Send Privately

Transfer FP with full privacy

ZK Proofs + Ring Signatures

Redeem

Burn FP → Get USDT back

24h timelock for security

1. Purchase Flow (Buy FP with USDT)

How to acquire Floating Points

01

Connect Wallet

Connect MetaMask or WalletConnect

02

Approve USDT

Approve USDT spending to protocol

03

Deposit USDT

USDT sent to Treasury address

04

Generate Commitment

Client creates Pedersen commitment

05

Receive FP

FP Tokens minted to your wallet

Example: Purchasing 10 FP Tokens

You Pay100 USDT

Protocol Fee (0.1%)-0.10 USDT

2. Transaction Flow (Private Payments)

How to send FP privately to another address

1

Selection

Gravity-Weighted Random Selection

Points are selected using a gravity-weighted algorithm. Older points have higher selection probability.

weight = mass × √(age + 1) × GRAVITY_CONSTANT

2

Nullifier

Generate Nullifier

A unique nullifier prevents double-spending without revealing which point you own.

nullifier = hash(pointId || secret)

3

ZK Proof

Zero-Knowledge Proof

Prove you know the secret, nullifier is correct, and values balance - without revealing anything.

proof = zkSNARK.prove(inputs, outputs, nullifiers, secret)

4

Ring Sign

Ring Signature

Sign with decoy public keys. Verifiers confirm one member signed but can't identify who.

σ = RingSign(msg, sk, {pk₁...pkₙ})

5

Broadcast

Submit to Blockchain

Contract verifies proofs, marks nullifiers as spent, mints new FP to recipient.

tx = {nullifiers, newCommitments, zkProof, ringSig}

3. Redemption Flow (Get USDT Back)

How to convert FP back to USDT

01

Select FP

Choose which FP tokens to redeem

02

Request Withdrawal

FP burned, request submitted

03

Wait 24 Hours

Security timelock period

04

Claim USDT

Call completeWithdrawal()

Example: Redeeming 10 FP Tokens

You Burn10 FP Tokens

Gross Value100 USDT

Protocol Fee (0.1%)-0.10 USDT

You Receive (after 24h)99.90 USDT

Why 24-Hour Timelock?

The timelock prevents flash loan attacks and gives users time to cancel if their wallet is compromised. You can cancel during this period to restore your FP.

4. Privacy Guarantees

How your identity remains hidden

Sender Anonymity

Ring signatures mix your tx with decoys. Observer sees N possible senders.

Ring size: 11 (1 real + 10 decoys)

Receiver Anonymity

Stealth addresses generate one-time keys. No link between recipient addresses.

New address per transaction

Amount Hidden

Pedersen commitments hide values. Only parties involved know amounts.

C = vG + rH (hiding + binding)

Unlinkability

No connection between deposits and withdrawals. Full transaction graph privacy.

Zero on-chain correlation

What Observers See

A transaction occurred
N possible senders (ring members)
Cryptographic proofs are valid
No double-spending occurred

What Remains Hidden

Actual sender identity
Actual receiver identity
Transaction amount
Link between deposit/withdrawal

5. Security Measures

How your funds are protected

Double-Spend Prevention

Nullifiers are stored on-chain. Each FP can only be spent once. Attempting to reuse triggers rejection.

24-Hour Withdrawal Timelock

All withdrawals require 24h waiting period. Allows cancellation if wallet is compromised.

Emergency Pause

Protocol can be paused by governance in case of critical vulnerabilities. Funds remain safe.

On-Chain Verification

All ZK proofs and ring signatures verified by smart contract. Invalid proofs rejected.

Client-Side Key Storage

Private keys never leave your device. Protocol never has access to your secrets.

6. Tokenomics & Value Stability

How FP maintains its $10 value

100% USDT Collateralized

Every FP Token is backed 1:1 by USDT held in the Treasury smart contract.

This is verifiable on-chain at any time by calling getReserveProof().

INVARIANT

Treasury ≥ FP × $10

BACKING RATIO

100% (Always)

Fixed Denomination

Each FP = exactly $10. No price fluctuation. No oracle manipulation risk.

No Inflation

FP only minted when USDT deposited. Total supply = Total USDT in Treasury / 10.
