Colb

Colb is a structured products platform on Plume Network that wraps private-market and index exposure into certificates subscribable in shares, aimed at on-chain capital seeking non-public assets through stablecoins. Such assets usually carry minimum tickets, lockups and eligible-purchaser limits, while secondary transfer lacks quotes and a clearing venue, leaving positions hard to adjust before maturity.

Each product is registered as a TKSP: the series states the underlying, coupon or participation rate, observation period and settlement waterfall, with principal and return calculated in tranches and terms written into contracts that take prices from an oracle. Subscription and redemption settle in $USC, a stablecoin issued under the Swiss regulatory framework, which shortens fiat on- and off-ramp steps. $COLB underpins an intent solver market where users post an intent to buy a series at a given price and solvers compete to fill it, producing a transfer price before maturity. In December 2025 the platform listed an index series linked to CSPX, referencing tokenised S&P 500 exposure.
