$SYNC utility: fees, staking, rewards, escrow bonds

Base-native

Low fees, fast finality, Coinbase alignment. $SYNC is the fee rail.

Trustless Escrow

Two-sided funding, expiry + refund, clean events for bots & UX.

Fee Tiers

Hold/stake $SYNC to reduce fees to 0% for qualified accounts.

$SYNC Token Utility

$SYNC routes value through the network: transaction fees, staking tiers (reduced/zero fees), rewards (cashback/referrals), and escrow collateral bonds. This creates recurring demand and network effects.

Fees: P2P Send and Escrow route fees via $SYNC.
Staking tiers: Standard 0.30% → Tier 1 (10k $SYNC) 0.10% → Tier 2 (25k $SYNC) 0%.
Rewards: Cashback + referrals in $SYNC.
Escrow bonds: Small collateral in $SYNC to reduce spam and anchor reputation.
Governance (later): $SYNC holders steer upgrades and parameters.
