Stablecoin payments on Ink

USDC payments at L2 fees.

Ink is Kraken's OP Stack L2. Tab settles in USDC here, the same canonical Circle stable used on every other supported chain, so your buyers and merchants never have to think about which dollar they're holding.

Why merchants pick Tab on Ink

Canonical USDC

Circle-native USDC on Ink, not a wrapped bridge variant. Same stable, same address pattern, same accounting your dashboard already uses on Base and BSC.

Sub-second finality

Ink's sequencer produces one-second blocks. Tab's webhook fires before the buyer finishes putting their phone down.

Kraken-backed

Direct off-ramp story for merchants who already have Kraken accounts. Settlement to USD bank wire is one step.

FOR DEVELOPERS

Drop into the Ink integration in a day.

Same EIP-712 signature, same router contract, same REST API you already use on every other chain. The only thing that changes is the chain id and the stablecoin address.

Technical notes

OP Stack parity

Same EVM as Base and Optimism. Tab's router contract is bit-for-bit identical across all three.

Optimistic finality

Like every OP Stack L2, full Ethereum-rooted finality takes ~7 days. Tab uses single-confirmation finality for in-protocol UX; the indexer reconciles on the unlikely event of a sequencer revert.

One stable, every chain

Tab unified on USDC across Base, BSC, Ink, Celo, and Solana. Merchants reconcile in a single currency, no per-chain stablecoin bookkeeping.
