Selected Projects (open source / on-chain verifiable)

Smart contracts — EVM (Solidity)

• RSS3 Network
  On-chain lifecycle for indexer nodes (creation, deposits, unbonding, rewards, and slashing) and user stake/redeem with settlement.

  • Core reward, slashing, and node-pool logic is split into library contracts so main flows stay within clear audit boundaries.
  • GitHub: https://github.com/RSS3-Network/RSS3-Network-Contracts

• RSS3 Pre-Staking
  Mainnet-verifiable pre-staking: tiered lock-ups for deposit/redeem, with rewards released over time (dividends branch).

  • Mainnet: https://etherscan.io/address/0x5301cbbedc048abac7e213184132cf982d593563
  • GitHub: https://github.com/NaturalSelectionLabs/Pre-Staking/tree/dividends

• Folo — PowerToken
  Utility token for content / feed scenarios: OpenZeppelin-based upgradeable ERC-20 with roles, non-transferable points, tipping and feed balances, daily mint caps, and more.

  • On-chain: https://scan.rss3.io/address/0xE06Af68F0c9e819513a6CD083EF6848E76C28CD8
  • GitHub: https://github.com/RSSNext/follow-contracts

• EVM Bonding Curve
  Bonding-curve launches and liquidity migration: virtual-reserve pricing, fee distribution, and migration; the dynamic variant supports multiple curve configs and AMM-style pricing parameters (implementation informed by Meteora).

  • https://github.com/iavl/bondingcurve-evm · https://github.com/iavl/dynamic-bonding-curve-contracts

• Crossbell — protocol, bridge, NFT marketplace
  Social protocol (identity, links, and content with mint/link policies), asset bridge between Ethereum and Crossbell (dual gateways + validator + quotas and mapping), and an NFT marketplace (listings, ERC-2981 royalties, ERC-777).

  • https://github.com/Crossbell-Box/Crossbell-Contracts
  • https://github.com/Crossbell-Box/crossbell-bridge-contracts
  • https://github.com/Crossbell-Box/xShop-contracts

Solana (Rust / Anchor)

• Smart Account · secp256r1 / WebAuthn
  Passkey-centric smart account: program and mint allowlists, authenticated contact changes, and delegated execution of arbitrary instructions under whitelist rules (reducing blind signing and malicious-program risk).

  • GitHub: https://github.com/iavl/smart-account-solana

• Bonding Curve Launchpad
  On-chain curve creation, trading, parameters, and withdrawals, with a built-in AMM submodule.

  • GitHub: https://github.com/iavl/bondingcurve-solana

Rollup / execution layer (Go)

• RSS3 VSL — OP Stack customization · Go, op-geth, OP Stack
  Modular L2 on the Optimism stack, with RSS3 as the gas token and NEAR DA / Celestia DA data-availability integration.

  • Execution: https://github.com/RSS3-Network/op-geth (rss3-main)
  • Coordination & components: https://github.com/RSS3-Network/optimism (rss3-main)
  • Celestia DA (example branch): https://github.com/RSS3-Network/optimism/tree/feat/celestia-da

• Crossbell op-geth
  EVM execution-layer fork for Crossbell, with free gas transaction support.

  • GitHub: https://github.com/iavl/crossbell-op-geth

Earlier public chains

• NetCloth Chain · Go, Cosmos SDK, EVM
  BPoS public chain: full in-app EVM (state transition and interpreter), supporting smart contracts and governance-driven upgrades.
  • GitHub: https://github.com/netcloth/netcloth-chain
