Harbor RWA Settlement
On-chain settlement rails for regulated asset references with policy-gated mint paths, NAV oracle integration, and qualified custodian segregation.
Harbor connects off-chain custody and attestations to transferable reference tokens: mint and burn paths are policy-gated, NAV updates are signer-quorum bound, and redemption queues remain observable to both issuers and investors.

Challenge
Tokenization had to mirror fund rules without leaking PII on-chain: asset eligibility, investor allow-lists, freeze and seizure flows, and deterministic settlement when custodians disagree or rotate.
Approach
We designed upgrade-minimal core contracts with peripheral modules for compliance lists, attestation verification, and epoch-based NAV commits. EIP-712 structured data backed operator actions; events and Merkle snapshots supported third-party verification. Integration tests simulated custodian failover, delayed redemptions, and partial asset substitutions.
Outcome
Placeholder programme narrative - RWA buyers will scrutinise closely; verify before publish. Stated headline: $28M in regulated asset references settled on-chain across 6 institutional counterparties with zero reconciliation breaks across 11 months.
