Bridging Worlds: Empowering Cosmos with an Ethereum NFT Bridge
Proposal Type: Standard Proposal
Proposal Contents (*the original text from the proposer)
Summary
Ark Protocol requests 47,600 ATOM (≈ $200 000, using a 30 d avg price of $4.20/ATOM) from the Community Pool to build an open-source, EVM-based NFT bridge compliant with ICS-721.
Motivation
Ethereum hosts a $15 B+ NFT market, but Cosmos lacks a direct, audited EVM-compatible bridge for ICS-721 tokens. By funding Ark Protocol to build and operate this bridge, the Hub:
- Unlocks instant NFT liquidity for ATOM holders
- Onboards EVM-native communities into Cosmos
- Accrues sustainable revenue, as all fees are held/swapped into ATOM
Project Scope
- Solidity ICS-721 Bridge Contract
- Front-end Toolkit for seamless transfer flows
- 12-month Operations: node hosting, monitoring, DevOps
- Security Audit & Remediation
Ark has production experience deploying CW-based NFT modules on Injective, Juno, Neutron, Osmosis, Stargaze, Terra - and contributed heavily to the core cw-ics721 and cw-nfts repos.
Budget & Milestones (Total: $200 000 / 47 600 ATOM)
| Phase | Amount (USD) | ATOM | Deliverable |
|---|---|---|---|
| 1) Development | $ 90 000 | 21 429 | Architecture & Solidity ICS-721 implementation |
| 2) Operations | $ 60 000 | 14 286 | 12 mo support: hosting, monitoring, DevOps |
| 3) Audit | $ 50 000 | 11 905 | Third-party security audit + remediation |
Funds are released in three tranches upon Dev Start, Testnet Deployment, and Mainnet Launch.
