CHAINS

Ink

Ink is Kraken's OP Stack L2. Tab settles in USDC here at sub-cent gas after relayer sponsorship.

Stablecoin

Circle's native USDC on Ink (6 decimals). The same Circle dollar Tab uses on Base. One canonical stable across every chain Tab supports.

Block time and finality

One-second blocks. As an OP Stack L2 it inherits Ethereum security with an optimistic challenge window for full L1 finality. Tab treats payments as settled at the first L2 confirmation.

Gas sponsorship

Tab's relayers pay the gas. Buyers only need to hold USDC to pay.
