Task: Multichain Governance System for DLE

Status

✅ Transfer proposal form works
✅ Proposals created in all DLE chains
✅ Voting in each chain separately
✅ Quorum per chain
✅ Personal transfer from proposal initiator
✅ Proposals grouped by description + initiator
✅ Server coordination with cryptographic proofs
✅ No hardcoded chains — deployedNetworks from API

Context

DLE (Digital Legal Entity) is a decentralized legal entity with contracts in multiple blockchain networks. The task is to implement token governance via multichain governance: token holders can transfer tokens through voting with quorum.

Architecture

Frontend: Vue.js with Web3
Backend: Node.js for coordination and API
Smart contracts: DLE contracts in each supported network
Database: PostgreSQL for metadata
WebSocket: Real-time sync across networks

Supported networks

Ethereum Sepolia (chainId: 11155111)
Arbitrum Sepolia (chainId: 421614)
Base Sepolia (chainId: 84532)

Functional requirements

1. Transfer tokens proposal form

URL: /management/transfer-tokens?address=<DLE_ADDRESS>

Fields: Recipient address (required), Amount (tokens, required), Description (optional), Voting duration (days, required).

2. Proposal creation

Get deployedNetworks from API /dle-v2
Create proposals in all DLE networks (sequentially with MetaMask; one proposal per chain)
Encode operation: _transferTokens(sender, recipient, amount) — sender = initiator

3. Voting

Voting is per chain
Quorum per chain: (forVotes / totalSupply) >= quorumPercentage
Vote weight = voter’s token balance

4. Execution

Each contract checks its local quorum
Backend aggregates quorum results and can sign global status
Execution with global quorum proof or per-chain execution

Technical spec (summary)

Proposal: id, description, forVotes, againstVotes, executed, canceled, deadline, initiator, operation, targetChains, snapshotTimepoint, hasVoted
_transferTokens(sender, recipient, amount) internal; emits TokensTransferredByGovernance
Backend: QuorumCoordinator (collect results, generate global proof)
API: GET /dle-v2, POST create/vote/execute proposal endpoints
Frontend: TransferTokensFormView (validation, encode operation, create in all chains), DleProposalsView (grouped list, status per chain, vote/execute)

Security

On-chain checks (balance, deadlines, quorum), cryptographic proofs for global quorum, validation, graceful degradation if a chain is down.

Testing

Acceptance: form works; proposals in all chains; voting per chain; quorum per chain; transfer from initiator; server coordination; grouping; error handling. Cases: create in multichain; vote when one chain down; execute with global quorum; execute with partial quorum (must fail); sufficient/insufficient initiator balance.

Deployment

Backend with RPC to all networks, DB, SSL, monitoring. Env: RPC URLs, DATABASE_URL, SERVER_PRIVATE_KEY for signing.

Fully functional multichain governance for DLE tokens is implemented, with decentralized decisions and optional trusted-server coordination with cryptographic proofs.
