Winning projects treated Arc as a true liquidity hub for invisible settlements multichain coordination and agent-driven commerce. Standout winners included chain-agnostic FX DEXes SMS-native DeFi tools self-paying corporate treasuries and AI agents earning micropayments through revenue-backed tokens.
