Every transfer
leaves a trail.

On a public chain, anyone can follow your money from one wallet to the next. Interphase breaks that link.

  • Private by Default

    Each transfer settles into a fresh address, leaving no on-chain link between sender and recipient.

  • Compliance at the Core

    Sanctions and limits are checked before funds move, while user data stays encrypted throughout.

  • 30+ Supported Chains

    Interphase launches on Bitcoin, Ethereum, Solana and TRON, with 30+ major chains to follow.

How Interphase Works

Transfer Request

The user selects the asset, the destination chain and the recipient. Interphase shows the route and the final amount before anything moves.

  1. Transfer Request

    The user selects the asset, the destination chain and the recipient. Interphase shows the route and the final amount before anything moves.

  2. Compliance Check

    Before the transfer is executed, it is checked against sanctions and limits. The check runs on encrypted data through COTI garbled circuits, so no one sees the user’s details.

  3. Settlement

    Funds settle into a fresh address on the destination chain in under 60 seconds, with gas included. Nothing on-chain links that address to the sender, and if a transfer cannot be completed, the funds are returned automatically.

Interphase is creating a private settlement layer for the multi-chain economy. Send, swap, and settle to pay, trade, and move money across 30+ chains. It is the next joint frontier in the privacy and cross-chain markets, and an embodiment of private transfers tied with the reach of every major blockchain.

Interphase:
Features and Function

Interphase is built for everyday use. The fundamental purpose is to make a private transfer as easy as a public one.

Get Early Access
  • One-Time Stealth Addresses

    Every payment generates a single-use destination address through client-side cryptography. On-chain observers see only an unlinked address.

  • Non-Custodial

    Neither Interphase nor COTI ever takes custody of your funds. Transfers execute peer-to-peer through decentralized solvers, smart contract escrows and local client signatures.

  • Malware & Drainer Shield

    Moving funds requires two cryptographic approvals: one from your device and one from an automated security co-pilot. Even if your browser or device is compromised, attackers cannot redirect or drain your funds.

  • Clean Funds

    Transfers are never pooled in a shared anonymity pool. Liquidity comes directly from market makers, so funds carry no shared history with other users.

  • Selective Disclosure

    Users can grant an auditor or accountant read-only access to specific transactions or time periods. Spending keys stay untouched, and the public sees nothing.

  • Gas Included

    Every transfer arrives with native gas already in the destination address. The recipient can spend, swap or sweep the funds immediately, without funding gas from a known wallet.

Interphase Roadmap

Interphase is being developed by COTI’s core team. The roadmap sets out three phases, each building on the last.

Read Full Roadmap
  1. Phase 1

    Q4 2026 – Q1 2027

    Private Cross-Chain Payments

    • Private multichain transfers (ETH, SOL, BTC, TRON) settled in <60s with native gas included
    • Malware & drainer shield via 2-of-2 co-signing protection on all temporary stealth wallets
    • Private transaction history that syncs in real time on your device, with no server-side tracking
    • Pre-flight Privacy Check (Proactive warnings before any action could link your identity)
    • Independent security audits of all smart contracts, cryptographic curves, and routing logic upfront
  2. Phase 2

    Q2 2027 – Q3 2027

    Business & Ecosystem Expansion

    • Native COTI App integration (Interphase SDK embedded as the flagship confidential engine)
    • Private travel booking (SDK-powered confidential hotel and flight checkout in 150+ countries)
    • Expansion to fast, sub-cent L2s (Base, Arbitrum, BNB Chain, Sui, and Aptos)
    • Confidential team payroll (1-click private stablecoin salary payouts with zero on-chain leaks)
    • Scoped auditor disclosure (Read-only viewing keys for seamless IRS/HMRC tax compliance)
  3. Phase 3

    Q4 2027 – Q1 2028

    Scale & Global Commerce

    • Universal Interphase SDK & 1-click merchant checkout widget for any Web3 website or dApp
    • Virtual spending cards (Everyday Visa/Mastercard spend funded from private balances)
    • Enterprise compliance layer (Clean funds proofs & sanctions screening for CEXes and OTC desks)
    • Batch multisender engine (Distribute up to 100 private transfers in a single transaction)
    • Hardware wallet cold integration (Direct private claim & sweep with Ledger and Trezor)
For Developers

Build Private Transfers
Into Any App

Interphase is built to be used beyond its own app. From Q4 2027, the Interphase SDK opens the same private transfers to wallets, exchanges, bridges and payment apps, so their users can move funds between chains privately, without leaving the product they already use.

Developers can join the early access list now.

  from: { chain: 'ethereum', asset: 'USDC' },

// Fresh address, gas included, refunded if it fails

Frequently
Asked Questions

  • Interphase is COTI’s flagship app for private transfers between blockchains. It moves crypto from one chain to another with no on-chain link between the sender and the recipient, and checks every transfer for compliance before the funds move.

  • Interphase launches on Bitcoin, Ethereum, Solana and TRON. Base, Arbitrum, BNB Chain, Sui and Aptos follow in the next phase, with expansion to 30+ major chains over time.

  • The link between the sender and the recipient. Each transfer settles into a fresh address, so nothing on-chain connects the two, and the amount is visible only to the sender and the recipient.

  • Yes. Before a transfer is executed, sanctions and limits are checked on encrypted data using COTI garbled circuits. No one sees the user’s details.

  • No separate wallet is needed. Interphase works as its own non-custodial wallet, so COTI never takes custody of your funds, and control stays with you at every step.

  • Every transfer shows the fee and the final amount before anything moves, with gas included. Market makers compete to fill each transfer, so users receive the best available rate.

  • Phase 1 begins in Q4 2026, with private transfers on Ethereum, Solana, Bitcoin and TRON. Join the early access list, and we’ll email you when early access opens.
