Built the founding product stack for a points marketplace that raised $2.77M
Pichi Finance is the first trustless points trading protocol, enabling users to trade points from their favorite protocols before TGE. Each position lived in a wallet-bound NFT: trading the NFT transferred the wallet (and its points/history) to the buyer.

How It Works
Mint an NFT bound 1:1 to an EOA wallet. Connect that wallet to point-earning dApps; points accrue to the wallet. List the NFT on Pichi; buyer acquires the wallet + its points on settlement.
EOA-per-NFT account pattern for maximum dApp compatibility. Marketplace + escrow contracts; indexers for balances/points snapshots. Relayers for gas and automated upkeep; event pipeline for position state.
Hardest Challenge
Using the NFT's EOA to sign on 3rd-party dApps. Built an EIP-1193 provider shim + WalletConnect profile so the NFT's EOA could 'connect' as a real wallet. Remote/MPC signing service with strict policy: whitelisted domains/contracts, EIP-712 typed-data schemas, rate limits, and per-op spend caps.
Session keys for repetitive calls; fallbacks for dApps using legacy personal_sign. Third-party dApps treated the NFT's EOA like any normal wallet, so points accrued seamlessly.
Outcome
Protocol secured $2.77M in funding based on the technical foundation. 12,000+ additional users and significantly improved retention after redesign. Validated EOA-per-NFT as a pragmatic path for broad dApp compatibility.
