Executive Summary
AZXBTC is a ERC-20 / Polygon token deployed on Polygon that provides on-chain price exposure to Bitcoin through an immutable pegging formula powered by Chainlink decentralized oracle infrastructure.
With a hard cap of 5,000,000 tokens and a staking layer distributing WBTC rewards, AZXBTC combines Bitcoin's store-of-value properties with DeFi income generation — accessible to any BSC wallet holder without requiring direct Bitcoin custody.
Core Properties
- 5,000,000 total supply — fixed forever, no minting function
- Price tracks BTC via immutable Chainlink oracle formula
- Staking rewards paid in WBTC — real Bitcoin on Polygon
- 1% to 10% APY across 5 transparent staking tiers
- Fully open-source, audited smart contracts on PolygonScan
- Non-custodial — users retain full key control at all times
Problem & Solution
Retail investors want Bitcoin exposure without the complexity of self-custody, hardware wallets, or bridging. Simultaneously, DeFi yields on Bitcoin-backed assets remain opaque. AZXBTC solves both: a simple ERC-20 / Polygon token that mirrors BTC price movements and pays transparent, sustainable yields verified on-chain.
Price Mechanism
The AZXBTC price is governed entirely by an immutable on-chain formula. No administrator, team member, or smart contract owner can override this calculation. The price is updated by calling the public updatePrice() function, which fetches the latest Chainlink BTC/USD data.
Core Formula
| Variable | Definition |
|---|
P₀ | Base price at deployment ($0.001 USD) |
BTC(t) | Current BTC/USD from Chainlink (8 decimals) |
BTC(0) | BTC/USD price at contract deployment |
If BTC rises 50% from deployment price, AZXBTC rises 50%. If BTC falls 20%, AZXBTC falls 20%. The relationship is linear and symmetric.
Oracle Safety
- Chainlink feeds update approximately every 12 seconds on Polygon
- Stale data protection: prices older than 3,600 seconds trigger a revert
- Negative price guard: any non-positive feed value reverts the transaction
- Owner can update the feed address to migrate to a new Chainlink aggregator
Token Economics
AZXBTC has a fixed supply of 5,000,000 tokens. There is no mint function beyond the constructor. The distribution is designed to ensure long-term sustainability and prevent early concentration.
| Allocation | Tokens | % | Vesting |
|---|
| Public Sale | 1,750,000 | 35% | At TGE |
| Staking Rewards | 1,500,000 | 30% | 3-year distribution |
| Ecosystem & Dev | 750,000 | 15% | 12-month linear |
| Liquidity Pool | 500,000 | 10% | At TGE, locked 1 year |
| Team & Advisors | 500,000 | 10% | 6-month cliff, 24-month linear |
Sale Rounds
| Round | Price | Supply | Min Buy |
|---|
| Seed | $0.001 | 500,000 | $10 |
| Private | $0.005 | 500,000 | $50 |
| Public | $0.01 | 750,000 | $10 |
5% of all presale proceeds are allocated to a BTC buyback-and-burn mechanism, reducing circulating supply and adding deflationary pressure over time.
Staking Protocol
The staking protocol is a planned 2027 feature. When launched, the staking contract will distribute WBTC proportionally to stakers based on position size and tier multiplier. Rewards will be funded by the 30% staking allocation and supplemented by protocol fees.
| Tier | Lock | APY | Reward Token |
|---|
| Flexible | No lock | 1% | WBTC |
| Bronze | 30 days | 3% | WBTC |
| Silver | 90 days | 6% | WBTC |
| Gold | 180 days | 8% | WBTC |
| Diamond | 365 days | 10% | WBTC |
Reward Sustainability
APY rates are intentionally conservative (1–10%) to ensure long-term sustainability from the 1.5M token staking reserve. This reserve, combined with protocol revenue, funds rewards for a minimum of 3 years without requiring additional token emissions.
- Emergency withdraw available — forfeits all pending rewards
- Claim rewards any time without unstaking
- Auto-compound feature routes WBTC back to staking (Q3 2025)
- APY parameters adjustable by governance vote only (post-DAO launch)
Security Model
Security is not an afterthought — it is embedded at every layer of the AZXBTC architecture. All contracts follow the checks-effects-interactions pattern and are protected against known attack vectors.
Contract Protections
- ReentrancyGuard on all functions that transfer value
- Pausable — emergency stop in under 2 minutes via multisig
- Ownable with 48-hour timelock for parameter changes
- Chainlink staleness check — reverts if feed data is older than 1 hour
- SafeERC20 wrappers on all token transfers
- Access control via OpenZeppelin Ownable v5
Audit & Bug Bounty
| Item | Detail |
|---|
| Security Audit | Full audit pre-mainnet deploy |
| Bug Bounty | Up to $50,000 USDC for critical |
| Multisig | 3-of-5 for all treasury ops |
| Code Verification | All contracts verified on PolygonScan |
Known Risk Vectors
- Oracle failure: mitigated by stale-data revert and fallback feed
- Admin key compromise: mitigated by 3-of-5 multisig and timelock
- Flash loan attacks: no flash-loan exploitable state changes
- Smart contract bugs: mitigated by audit, test coverage, and pause capability
Governance
AZXBTC will transition to fully decentralized governance in Q4 2025. Until then, the founding team operates a multisig for contract management with all actions subject to the 48-hour timelock.
DAO Parameters
| Parameter | Value |
|---|
| Voting Weight | 1 AZXBTC = 1 vote |
| Proposal Threshold | 100,000 AZXBTC to submit |
| Voting Period | 72 hours |
| Quorum | 10% of circulating supply |
| Execution | On-chain, automatic after quorum |
- Team retains no special voting rights after DAO launch
- Protocol fees, staking APY, and treasury spending all governed by DAO
- Constitution document governs what can and cannot be changed
