Optimex
About
Optimex is a Bitcoin-native finance platform that enables users to borrow stablecoins, earn yield, and perform cross-chain swaps while retaining full self-custody of their BTC in Bitcoin-native multisig vaults — no wrapping, bridging, or centralized custody required. Designed for both retail and institutional participants, it offers overcollateralized USDC borrowing against native BTC, an RFQ-based swap engine with professional market makers, and the ability to deploy borrowed stablecoins into curated DeFi strategies for additional yield.
Where Does Yield Come From?
Optimex generates yield from several sources that work together. Here is how each one works.
1. Borrowing against your Bitcoin (Optimex Borrow)
You deposit native Bitcoin into a multisig vault (a shared wallet requiring multiple signatures). You keep joint control — you are one of the signers. From that vault, you can borrow USDC at rates set by the market. Your Bitcoin stays native on the Bitcoin blockchain; it is never wrapped, bridged, or handed to a custodian. Because nothing changes ownership, there is no taxable event when you deposit.
2. Earning yield on the stablecoins you borrow
Once you have borrowed USDC, you can put those funds into a handpicked set of outside DeFi lending and liquidity protocols. This creates two ways to earn at the same time: your Bitcoin can rise in value, and the stablecoins you borrowed can also earn returns in those external markets.
3. Swapping tokens (Optimex Swap)
Cross-chain swaps happen through a Request-for-Quote system with professional market makers. This design removes MEV (a kind of front-running) and slippage (unexpected price changes during a trade). Optimex charges a small fee per trade: 0.02% for BTC–WBTC pairs and other wrapped Bitcoin pairs, and 0.1% for all other trading pairs.
4. Validator staking and security
A Decentralized Validation Network uses threshold signatures (a method where multiple parties must sign off) to check that loans and swaps are valid. Node Operators put up bonded collateral in ETH or ERC-20 tokens. If they misbehave, some of that collateral is taken away (slashing). This aligns everyone's incentives toward honest operation.
5. Fee distribution
Wallet apps that integrate Optimex can add their own affiliate fee (measured in basis points), which Optimex collects on their behalf. A referral program shares 20% of protocol fees with standard referrers and 30% with partners or key opinion leaders (KOLs) — all based on fees generated by the people they referred.
There is no native token or inflation schedule described in the current documentation. The yield comes from borrowing spreads, swap fees, and returns from external DeFi protocols, not from protocol-issued incentives.
Audits
| Audit / Date | Findings | Verdict |
|---|---|---|
Offside Labs04-03-2025 - 26-03-2025 |
| The audit found no critical or high-severity vulnerabilities; the single medium and one low issue were fixed, while the remaining findings were acknowledged by the Optimex team with documented off-chain or process-level mitigations. Overall the smart contract code presents a low residual security risk for the audited scope. |
