RarePepe.fun Bridge: Counterparty → Solana cNFTs (Single-Asset Wraps Model)

Table of Contents

About the Bridge

What is RarePepe.fun?

Rare Pepe cards and other Counterparty (XCP) NFTs are crypto history—but live on the Bitcoin chain, like on the gold standard. While this grants unmatched provenance and durability, it comes at the price of being slow, expensive, and inaccessible to many.

The RarePepe Bridge unlocks these assets by wrapping each one in a dedicated, cryptographically secure container and issuing a Solana compressed NFT (cNFT) as the sole access token. This lets legacy NFTs move to Solana for fast, modern, cheap trading—while preserving Bitcoin provenance.

Why Solana?

Collateralize shit assets/tokens with Historic Assets Wrapped vintage NFTs with nearly a decade of onchain history can now be used as collateral or anchors for DeFi projects.

Cost Efficient Wrapping cNFTs on Solana drastically reduces transaction fees compared to Ethereum or Bitcoin.

Blazing Fast Solana’s lightning-fast blockchain enables near-instant trades.

Easy to Collect Solana’s ecosystem is user-friendly, widely adopted, and makes it simple to manage, store, and showcase collections.

Reach a Broader Audience Crosschain, IRL(codes), and Solana’s popularity is growing with active traders, collectors, developers, and artists.

Why Compressed NFTs on Solana? Despite the technical complexity, compressed NFTs guarantee minimal costs and maximum speed.

"So we thought—why do it differently?"

Bitcoin Counterparty vs Solana cNFTs: Cost & Speed Comparison

Bitcoin/Counterparty Solana cNFTs (Bridge Solution)
Average Transfer Fee $2–$30+ (varies, can spike higher) <$0.01 (usually <1 cent)
Confirmation Time 10–60 minutes (1–6 blocks, network dependent) 1–5 seconds (block time)
Batch Minting Expensive, not practical Built-in and dirt cheap
NFT Minting Cost $2–$50+ per asset <$0.25 per asset (compressed)
User Experience Complex, legacy wallets, slow UX Instant, mobile-first, smooth UX
Access to Markets Niche, limited Global, direct to Magic Eden/Tensor
Scalability Low High (100k+ NFTs in one go)
Royalties Support None Native, enforced on-chain
Interoperability Bitcoin only Chain-agnostic, programmable

Bottom line:
Solana cNFTs are 100–1000x cheaper, 100x faster, and orders of magnitude more accessible for users, artists, and collectors.

Instructions

Wrap

  1. Connect your Solana wallet and sign in
  2. Select the RarePepe card you want to wrap from the quick menu
  3. Confirm and pay the wrapping fee - optional: create a coupon that will mint the cnft to the user that redeems it
  4. You will receive a custom BTC address for your wrap
  5. Send exactly quantity 1 of the chosen RarePepe card to your custom BTC address
  6. Wait for XCP transaction confirmation
  7. Receive your wrapped RarePepe as a cNFT on Solana

Cost: 0.02 SOL → 0.01 SOL

Unwrap

  1. Connect your Solana wallet and sign in
  2. On the overlay of each card, you’ll see function buttons—choose Redeem (unwrap)
  3. In the overlay, you’ll now have two buttons: Redeem and Burn
  4. Choosing Redeem prompts your wallet to send a transaction to open the order and pay the fee, followed by a transaction to burn the card
  5. Once the card is burnt and all onchain checks are complete, you can view the private key for every asset redeemed in your orders row
  6. Click “Reveal”, sign a message to prove it’s you, and the private key will be displayed on screen

OG Creator Royalties

A missing piece in the XCP architecture — long awaited in wrapped Pepes — OG Royalties are finally here.

All verified RarePepe creators are invited to pair their original BTC wallet (e.g., Freewallet, Sparrow, RarePepeWallet) with a Solana wallet. This allows the bridge to automatically assign royalty shares on future trades of their wrapped cards — wherever royalties are supported.

How it works:

  1. Sign a message with your BTC address proving you're the creator.
  2. Submit your BTC address and signature on the sign-in page.
  3. Your connected Solana wallet will be permanently linked to that creator address.
  4. Future cNFTs wrapped from that RarePepe asset will apply royalties to your Solana wallet.

⚠️ Note: Due to how on-chain metadata is set at mint time, this cannot be applied retroactively to cNFTs already wrapped before the wallet pairing.

Coupon Codes & Minigames

Coupon codes are pre-filled wraps that can be distributed in many creative ways — online or offline — to make RarePepe cNFTs easier to access. They can be distributed with a wide spectrum of modalities (click-reveal, FCFS, customized). These can serve as:

  • In-game assets
  • Cashback rewards
  • Treasure hunt bounties
  • Event giveaways

🔥 Everyone can request/order a coupon:
If you want to create your own giveaway, you can order a coupon (pre-filled wrap) for any listed Pepe. These can then be distributed to others in code or physical format, and redeemed at any time.
Just specify the asset and it can be prefunded for anyone (even for self-custody, gifting, or IRL events).

Anyone in possession of a valid coupon code can redeem it for a pre-wrapped cNFT. Once redeemed, the coupon is automatically voided (FCS: First Come, Single-use), ensuring one-time exclusivity and fair claim.

This makes RarePepes more playful, collectible, and accessible — bridging communities both digitally and IRL.

🔥 ### Minigames, Prizes, and FCFS Drops

Minigames now pop up from time to time, giving users a shot to win RarePepes through a mix of skill and luck. Prizes are always limited and distributed first come, first served due to the value of the cards.
These minigames are a proof-of-concept for ultra-fast, chain-agnostic NFT giveaways, showing off live interoperability between the Solana Rare Pepe Wrapped and many context.
Win a Pepe, if you’re fast and sharp enough!

GudTek Philosophy

🌱 GudTek Principles

“Built by vibe. Guided by intent. Shipped by kanban.”

GudTek is not dictated by markets — it manifests through inner coherence. It's the art of building Rube Goldberg machines with lean hands, the joy of seeing systems bloom not from pressure, but from clarity.

These are its working principles:

🧠 The GudTek Principles

  1. Intent Over Incentive
    Create what resonates, not what sells.

  2. Vibe is the Compass
    If it doesn’t feel right, it isn’t.

  3. Form Follows Delight
    Simplicity and joy outrank technical complexity.

  4. Genuinity is Architecture
    Authenticity isn't decoration — it’s the foundation.

  5. Kanban Zen
    Work visible, scope minimal, flow sacred.

  6. Rube Goldberg Elegance
    Complexity can be graceful — if approached with wit and care.

  7. Prototype as Ritual
    Build fast. Break ego, not flow.

  8. Craft in Public
    Let the process be visible. Let the gud people see the soul.

  9. Refactor the Soul
    Not just code — clean intents too.

  10. Deadlines ≠ Lifelines
    Work moves through rhythm, not pressure.

  11. Own the Stack, Share the Snack
    Autonomy is power. Sharing is joy.

  12. Unmarketable ≠ Invalid
    If nobody sees it yet, you're early. Stay.

  13. Bugs are Spirit Guides
    Every glitch teaches. Listen before fixing.

  14. The Machine is a Mirror
    Your systems will reflect your inner life. Keep both simple.

  15. Done is a Frequency
    Tune into the moment where it feels complete.

This bridge is a functioning proof of concept — a weekend experiment. We recommend using it at your own risk, and initially only with low-value assets. If no exploits emerge over time, confidence may naturally grow.

Importantly, this P.o.C. opens up possibilities for strong real-life use cases. Think, for example, about enabling instant BTC payments for prepaid amounts, direct unlocking of assets based on simple onchain proof, or integrating digital ownership with DeFi settlement rails.

The system’s security relies on a Byzantine-style architecture, operating under the GudTek assumptions: that all best practices are followed to keep it simple and prevent double spending.

There is no known method to force the creation of a Solana asset with the original collection's mint authority without placing a verified order and depositing an unspent counterpart of equal value. The reverse is also true: without a cNFT minted by the authority—acquired through wrapping or secondary trade—and linked to a unique unspent output, it is impossible to unlock the corresponding asset on the XCP/BTC side. All balances are on-chain and publicly verifiable.

A centralized ledger and crank mechanism are currently required to monitor and match incoming transactions, triggering only provenance-verified counterpart actions. This ensures an auditable 1:1 balance between wrapped and unwrapped assets. Future versions will aim to push decentralization as far as current technology allows (which, realistically, still requires some central coordination).

✅ Return BTC privkey WIF ondemand from SecureVault software

Technical & Security Overview

  • Model: 1:1 single-asset wraps. Every XCP asset gets its own wrap, only ever holding that asset. The private key for each wrap is never stored; it is deterministically derived on-demand using a master seed and asset-specific salt.

  • Tamper Resistance: If tampering is detected, proprietary technology vault self-destructs safely—removing all traces, and making it unusable for future queries until respawn.

  • Bridging Flow:

  • Wrap: User sends their XCP asset to a unique wrap address.

  • Proof/Verify: Bridge backend watches for asset transfer, verifies on-chain, and triggers cNFT mint.
  • Mint: Backend mints a compressed NFT (cNFT) on Solana, representing the wrap’s contents. cNFT is sent to user.

  • Unwrap: User sends cNFT to the system. Backend burns it, derives the private key in RAM, and releases the XCP asset.

  • Memory-Only Keys: Keys are never saved—only generated temporarily in memory upon request, with no possibility of leakage.

  • Checksum Locking: Vaults are directory-locked using SHA256 hashes; duplication triggers secure halt.

  • Cross-Controls: Duplicate wraps, race conditions, and double-spends are blocked with multi layered checks and logs, onchain and partly offchain.

  • Isolation: Each wrap is independent. A failure in one cannot compromise another.

Risks & Security Considerations

  • Trust-Minimized: Deterministic, stateless wraps reduce internal risk.
  • Key Recovery: The master key is cold-stored, encrypted, and only decrypted at runtime. It is never exposed to disk, nor retained after session.
  • Frontend/Backend Bugs: While fully logged and auditable, bugs, especially from the Solana API responses, may delay asset delivery.
  • Unwrap Risk: Without cNFT return, XCP asset cannot be released.
  • Chain Risks: Solana or Bitcoin congestion may delay delivery.
  • Asset Provenance: If you send an asset to be wrapped, control transfers to the bridge wrap encryption system until unwrapped.

Risk Mitigation & Guarantees

  • No Persistent Keys: The private key is derived only on demand. No WIF or seed is stored.
  • Seed Encryption: The seed is encrypted at rest, and only decrypted in volatile memory upon startup with password.
  • Self-Destruct on Tamper: If the vault detects unexpected changes, it purges itself instantly—including its logs, memory, and the seed is never present, not even encrypted.
  • Internal Audit Frequency: A self-check process audits ledger-state and integrity every n minutes.
  • Emergency Recovery: The vault can be reset and restored from a clean copy. Users with legitimate ownership can always recover their assets using deterministic reconstruction.
  • No Wrap Reuse: Each wrap is single-use, non-repeating, and non-fungible.
  • Public Traceability: Every wrap, burn, and redeem is visible on-chain.
  • No Liability: This software is community-built and experimental. Use at your own discretion.
