otc

OTC — peer-to-peer token exchange for ERC20 and SOL holders.

Traders needed a product to discover OTC opportunities, manage proposals and execute private exchanges beyond public order books.

We engineered a blockchain-backed P2P exchange UI and flows: listings, negotiations and settlement-oriented screens tied to the underlying chain logic.

Frontend, backend and blockchain pieces shipped as one product crew. Result: a live OTC surface holders can operate without stitching tools together themselves.
