Proposal: Hyperlane Integration on Terra Classic — Multichain Connectivity with Ethereum, BSC, and Solana

Summary

This proposal seeks approval to deploy the Hyperlane protocol on the Terra Classic (LUNC) blockchain, enabling decentralized bridges with Ethereum (ETH), Binance Smart Chain (BSC), and Solana (SOL).

The project also includes the development and customization of a Hyperlane Warp UI, fully compatible with CW20 tokens from the Terra Classic ecosystem.

Implementation will be completed within 30 days, and payment will only be made after full deployment and verification in production.

Motivation

Currently, official bridges such as Wormhole have discontinued infrastructure support for Terra Classic.
As a result, native coins (LUNC and USTC) and CW20 tokens have lost the ability to transfer across chains.

This left the Terra Classic ecosystem isolated within its own liquidity bubble, restricted to DEXs on the same blockchain and unable to access larger global markets.

Hyperlane offers a decentralized, community-controlled, and open-source alternative, ensuring that the infrastructure (validators and relayers) belongs to the community itself.
This removes the risk of third-party discontinuation or dependency, as the bridge becomes fully community-operated.

Why Hyperlane

Hyperlane is a modular interoperability protocol that enables secure cross-chain communication, token transfers, and contract calls between blockchains — with no intermediaries.

Key Benefits

  • Decentralized infrastructure operated by the community
  • Integration with Ethereum, BSC, and Solana
  • Expanded global liquidity for CW20 tokens
  • Support for native assets like LUNC and USTC, as well as CW20 tokens such as Juris, Sele, Terra, Base, Cookier, and others

Access to Global Liquidity

With Hyperlane, CW20 tokens can be wrapped and listed on major DEXs:

Network Potential DEXs
Ethereum Uniswap, Curve, Balancer
BSC PancakeSwap, Thena, Biswap
Solana Jupiter, Raydium, Orca

This integration will allow Terra Classic assets to reach new markets and investors, breaking the liquidity bubble currently confined to the blockchain’s own DEXs.

Technical Overview

Implementation involves the following steps:

  1. Deploy core Hyperlane contracts: Mailbox, Interchain Gas Paymaster (IGP), ValidatorAnnounce, and ISMs
  2. Configure four independent validators, with open slots for community members to apply
  3. Set up relayers responsible for delivering cross-chain messages
  4. Create bridge contracts for CW20 ↔ ERC20 / BEP20 / SPL tokens
  5. Develop and customize the Warp UI for multi-chain swaps
  6. Publish documentation explaining how to create and maintain Warps, assisting other developer teams with future maintenance

Important Notes

  • Even with documentation, Warp creation is highly technical and should only be handled by experienced developers.
  • To maintain reliability, validators must stay active — inactivity can lead to community voting for replacement.
  • The Warp UI requires its own hosting infrastructure (e.g., React web server or hosting service).
  • The source code will be publicly released, allowing community members to host and maintain the interface.

Warp UI Customization

A custom fork of the official Hyperlane Warp UI will be developed with specific adjustments for Terra Classic:

  • Accurate CW20 token balance calculations using the Cosmos SDK
  • Adaptation for automatic approval via transfer_from
  • Smooth visual integration between Terra Classic and other networks
  • A clean, user-friendly, open-source interface accessible to everyone in the community

Validators and Rewards

The system will operate with four independent validators, open to community participation.

Each validator must use a KMS (Key Management Service) or WS-secured environment for key management.

According to the official Hyperlane documentation:

  • Validators can receive protocol rewards (Validator Rewards)
  • Relayers can charge transaction fees
    (docs.hyperlane.xyz)

Minimum Infrastructure Requirements

  • 2 vCPUs
  • 2–4 GB RAM
  • 4 GB storage

Considering redundancy, KMS/WS, backups, and maintenance, an operational grant of $90/month per validator is proposed.

Future Networks

The initial setup will include Solana, BSC, and Ethereum.
In future proposals, other developers may expand the bridge to additional networks supported by Hyperlane, such as:

Arbitrum, Avalanche, Polygon, Celo, Gnosis Chain, Moonbeam, Optimism, Fantom, Harmony, and Aurora.

Budget

Item Description Amount (USD)
Hyperlane Infrastructure Full deployment of contracts, validators, and relayers $9,000
Warp UI (Fork) Adjustments, CW20 integration, and source code release $3,000
Validator Support (4x) Infrastructure + KMS/WS ($90 per validator/month) $360/month

:light_bulb: Total Initial Cost: $12,000

Timeline

Phase Description Duration Status
Research & Testing Over 3 months of local development and testing :white_check_mark: Completed
Deployment Contracts, validators, and relayers setup 30 days :hourglass_not_done: Pending
Warp UI Visual integration and UI adjustments Parallel to deployment :hourglass_not_done: Pending

Payment Conditions

Payment will only be made after full production deployment and community verification.

Risks and Responsibility

  • Hyperlane is an independent, open-source protocol maintained by a global community
  • The proposer is not the owner of the protocol, but the developer responsible for installation
  • Any issues or bugs in the base code are not the responsibility of the installer
  • Installation will follow official documentation and best practices

Expected Impact

  • Restores interoperability lost after Wormhole discontinuation
  • Builds a community-owned, decentralized infrastructure
  • Expands Terra Classic’s reach into major DeFi ecosystems
  • Increases liquidity for LUNC, USTC, and CW20 tokens
  • Strengthens innovation and technical growth within Terra Classic

Conclusion

The Hyperlane integration marks a crucial step toward restoring interoperability and liquidity for Terra Classic.
With a community-controlled decentralized infrastructure, we secure autonomy, resilience, and long-term sustainability for the network.

With a modest budget and a 30-day timeline, this proposal empowers the Terra Classic community with control over its bridges, tokens, and future.

Support this proposal. Hyperlane is the only viable decentralized cross - chain solution for Terra Classic. Opposing it means accepting liquidity depletion. This is not something “nice to have”, but a lifeline for the Terra Classic ecosystem.

BiNodes applies to operate as a cross - chain validator. We have the following advantages:

  1. We are already Terra classic validators, possessing the experience and ability to run and maintain nodes in the long - term.
  2. We have the ability to deliver and manage redundancy & monitoring for ultra - large - scale access services. The community public API endpoints we provide have over 2 million daily calls.
  3. We have code research and development capabilities and are the authors of the community data analysis Python SDK and the analysis tool website https://www.binodes.com.
  4. We have the ability to integrate and maintain distributed systems and are the maintainers of the local Terra chain distributed big data platform.
  5. We have a deep obsession and belief in Terra classic and will not easily stop operating due to the overly low price of LUNC.

“The system will operate with four independent validators, open to community participation.”

Can you explain why 4 is chosen?

What does open to participate mean? Does it mean more validators can join in?

Thank you for all the work you already put in Igor

Also, make the reward standard for all participants, it will get confusing otherwise, if paeticipants do not need or want the reward they can donate it to cp or whatever they like.

I think the standard should be payment for work

I haven’t set a specific number of validators yet — I just know we need a minimum, which in practice can be three. I’m suggesting four to make it more decentralized. For example, the Ethereum network has nine validators, Solana has five, and BSC has six.

I’ve seen some networks that run with only two validators — it works, but I wouldn’t really recommend it.

In reality, the ones who decide how many validators will validate are the Warp creators — in this case, the token owners who configure the setup. For example, they can set policies like 3/1, 4/2, 4/3, or even 4/1, meaning that in those cases, 1, 2, or 3 validators would need to sign to authorize a transfer.

Some have asked how the paid validators would be chosen — I suggested doing it through a random draw, using any of the many online tools available for that. This helps avoid conflicts or favoritism.

Of course, in cases like Allnodes and Hexxgon, which already have their own infrastructure, I believe it’s very important for them to participate as validators too — but that’s up to them.

Good point — I agree that having a standard reward makes things clearer and fair for everyone. However, I’m currently checking with the other validators to see what they think about this, since three of them have already said they don’t want to receive the $90 monthly support.

Some people have also asked who would have the right to receive this reward, so the plan is to make that decision through a random draw to ensure fairness. I believe having up to six validators would be ideal — we don’t really need more than that to maintain good decentralization and efficiency.

:loudspeaker: Attention Terra Classic Community!

After receiving feedback from several validators, I decided to create a new proposal that removes the $90 compensation, since we already have 4 confirmed validators who will validate voluntarily and free of charge, reaching the required quorum in a decentralized way.

If there are other validators interested in supporting the community, please contact me via DM.
