EMBER

What it is

Ember is a milestone-based crowdfunding dApp on Morph L2 where backers contribute USDT into a per-project escrow contract and receive an ERC-721 position NFT. Funds release only after backers approve each milestone in an on-chain vote weighted by their contribution. An indexer service mirrors every on-chain event into Postgres, keeping the blockchain the source of truth for all value movement.

Value

• Backers don’t get burned. Money sits in escrow, not a founder’s wallet — a project that stalls at milestone 2 can never claim milestone 5’s funding.
• Creators get credible funding. Verified orgs raise against a public, bps-weighted milestone plan; trust comes from the contract, not platform reputation.
• No human discretion in the loop. Code decides fund release. No support ticket overrules a vote, and no upgrade key exists on the deployed escrow.

Technology highlights

• Non-custodial milestone escrow on Morph L2 — a ProjectFactory deploys an immutable ProjectEscrow and PositionNFT pair per project. The app only builds calldata; the user’s wallet signs every value-moving transaction.
• Event-sourced indexer with a milestone keeper — watches chain events with confirmation depth and idempotent backfill, sweeps expired voting windows to resolve milestones, and drives the email queue off the same lifecycle.
