Prototype · Atomic Cross-Chain Swaps

Swap Chains.
Trust No One.

Razor Wallet is the first self-custody wallet with native atomic cross-chain swaps — move assets between Bitcoin, Ethereum, Solana, and more with zero bridges, zero wrapped tokens, and zero counterparty risk. Trustless by design.

// Why Razor Wallet

Swap Without Asking for Permission

Bridges get hacked. Wrapped tokens have custodians. CEX swaps require KYC. Razor uses Hash Time-Locked Contracts — the only swap mechanism that needs nobody's trust.

⚛

True Atomic Swaps

HTLC-powered cross-chain exchanges that either complete in full or revert entirely. There is no intermediate state where funds can be stolen or lost.

🚫

Zero Bridges

No bridge smart contracts. No cross-chain messaging. No oracles. Just cryptographic hash locks and time locks securing the swap natively on each chain.

🔑

Self-custody Always

BIP-39/44 HD wallet — your keys never leave your device. Atomic swaps are peer-to-peer; Razor Wallet never holds your funds at any point in the process.

⚡

Multi-chain Native

Bitcoin, Ethereum, Solana, Arbitrum, Cosmos, and Avalanche at launch — all sharing the same atomic swap engine with a unified interface.

🤝

No Counterparty Risk

The cryptographic contract guarantees: if the counterparty fails to complete, your funds are automatically refunded after the time-lock expires. Always.

Full On-chain Audit Trail

Every swap step — lock, reveal, claim, refund — is a verifiable on-chain transaction. Full transparency, no black-box intermediaries.

How an Atomic Swap Actually Works

An atomic swap uses Hash Time-Locked Contracts (HTLCs) on each chain simultaneously. The math guarantees neither party can cheat — and no third party is involved at any step.

Both Chains

Secret Pre-image Generation

The initiating party generates a cryptographic secret S and publishes its hash H(S). Neither party knows S yet — only the initiator.

Chain A (e.g. Bitcoin)

Initiator Locks Funds with HTLC

The initiator deploys an HTLC on Chain A locking their asset: claimable by the counterparty only if they reveal S within the time-lock window.

Chain B (e.g. Ethereum)

Counterparty Locks Their Funds

Seeing the lock on Chain A, the counterparty deploys a matching HTLC on Chain B using the same H(S) — but with a shorter time-lock.

Chain B → Chain A

Reveal, Claim, Complete

The initiator claims from Chain B by revealing S. This reveals S publicly, letting the counterparty claim from Chain A. Both claims succeed or both time-locks refund. Atomic.

Common Questions

What exactly is an atomic cross-chain swap?

An atomic swap is a cryptographic protocol — using Hash Time-Locked Contracts (HTLCs) — that lets two parties exchange assets on different blockchains simultaneously, without any third party or bridge. The swap either completes in full for both parties, or neither side sends anything. The "atomic" in atomic swap means indivisible: there is no intermediate state.

How is this different from using a bridge?

Bridges hold your assets in a smart contract (or with a multisig group) on the source chain and issue a wrapped token on the destination chain. This creates custodial risk — the bridge is a honeypot. Over $2 billion was stolen from bridges in 2022 alone. Razor's atomic swaps use HTLCs deployed directly on each chain: no bridge contract, no wrapped token, no custodian.

What happens if the swap doesn't complete?

Every HTLC includes a time-lock. If the counterparty doesn't claim within the agreed window, the time-lock expires and your funds are automatically refunded to you — on-chain, no manual intervention required. It is cryptographically impossible for you to permanently lose funds in a correctly constructed atomic swap.

Which chains are supported in the prototype?

The current prototype targets BTC ↔ ETH atomic swaps as the primary pair, with Solana, Arbitrum, Cosmos (via IBC extension), and Avalanche in active development. We are building a chain-agnostic HTLC abstraction layer so new chains can be added with minimal integration work.

When can I download the wallet?

Razor Wallet is in the prototype stage and is not yet available for public download. Beta testers accepted through this program will receive exclusive early access before any public release. Apply via email or Telegram to get in the queue.

Does Grey Dog Software hold my keys or funds?

Never. Razor Wallet is fully non-custodial — your seed phrase is generated on your device and never transmitted anywhere. During an atomic swap, your funds are locked in an HTLC deployed from your own wallet address — not held by us. Grey Dog Software has zero access to your assets at any stage.
