A real bond issued with Hedera's Asset Tokenization Studio — whitelist-gated, held by real testnet investors — and a secondary market that cannot bypass the bond's own compliance check, because it never tries to move tokens any other way.
ATS bond tokens are ERC-1400/partial-ERC-3643 Diamond-proxy contracts with a standard ERC20 surface underneath. The marketplace below is deliberately dumb — it holds nothing in custody and has no special transfer path of its own.
A whitelisted holder calls the bond's own approve(marketplace, amount) — a standard ERC20 allowance, tokens don't move yet.
The seller lists an amount and price on the marketplace contract. Still no bonds have moved.
Any address can call buy() with the exact HBAR price attached.
The marketplace calls bondToken.transferFrom(seller, buyer, amount) — the same compliance-checked path every other transfer of this bond uses. A non-whitelisted buyer's purchase reverts right here.
Only after the bond transfer succeeds does the marketplace forward the HBAR — one atomic transaction, or none of it happens.
Real Hedera testnet contracts, deployed and verifiable on HashScan — see the README for the full list and deploy transactions.
Every bond issuance, whitelist grant, listing, and trade on the dashboard is a real Hedera testnet transaction — nothing mocked, nothing simulated.
The compliance gate is ATS's own internal control list, not a separate check this project invented — see the README for why, and for the KYC-vs-whitelist tradeoff made here.
