Caster

Caster is a layer one designed specifically for prediction trading, with 200 millisecond blocks and orders matched on-chain one by one rather than handed to an off-chain book, so quoted prices and on-chain state stay in step. Fees are fixed by schedule and makers earn a rebate on every fill.

Each market is bootstrapped by the Caster Liquidity Pool, which prices dynamically against inventory risk and time to resolution to give thin markets initial depth, while cancel priority lets makers quote tighter spreads. It presents itself as a prediction-native chain that keeps matching, clearing and pricing on one consensus layer, and its architecture leans harder on its own block cadence and fee certainty than markets deployed as contracts on general-purpose chains. A market clears once at expiry against the oracle result, open orders are cancelled automatically, and the settlement price is separated from the last quoted level. Fees are set separately for makers and takers.
