Ink

Ink is Kraken's OP Stack L2. Tab settles in USDT0 — Tether's canonical L2 deployment — at sub-cent gas after relayer sponsorship.

Stablecoin

USDT0 on Ink (6 decimals). USDT0 is the cross-L2 canonical Tether rolled out alongside the Tether/Tron LayerZero work — it's the same dollar, not a wrapped bridge variant.

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 USDT0 to pay.
