RWA settlement layer · Creditcoin x Attestcoin

Verified payment.
Deterministic ownership.

Your buyer pays USDC on Ethereum. Your asset releases itself on Creditcoin. No bridge, no wrapper, no trusted worker.

ERC-1155 leaves escrow

How it works

Payment stays put.
Ownership moves
with proof.

Before escrow opens, Credo locks the deal to one buyer, one token, one amount, one block window. Nothing else can release it.

Your RWA flow, backed
by verifiable evidence.

Exact payment

The official USDC Transfer must match the bound buyer, recipient, token, and raw amount.

Proof validation

Merkle inclusion, chain continuity, receipt success, and the Transfer log are checked together.

Escrow control

The ERC-1155 stays locked until verified settlement or the delayed reclaim window.

From listing to settled,
in five stages.

You always know which stage your sale is in—and what happens next, even if the browser closes.
