core modules

1. arc multi-chain identity

• handle registry: maps custom handles (e.g., @handle) deterministically to 0x wallet addresses.
• treasury tracking: displays real-time arc treasury balances and issues verified builder stamps.

2. asset routing & settlement engine

• native usdc routing: direct transfers via native gas usdc or erc-20 contract mechanisms.
• circle cctp bridge: integrated cross-chain liquidity routing.
• execution benchmarks: real-time speed monitoring for sub-second deterministic settlement.

3. programmable fee engine

• auto-split payments: automated revenue distribution (e.g., creator fees, protocol split, treasury yield).
• cross-chain royalties: programmatic distribution directly on arc network.

4. merchant pos & yield vault

• pos qr invoices: dynamic qr generation with integrated camera scanner for instant point-of-sale payments.
• audit logs: exportable csv verification logs tied directly to arcscan transaction hashes.
