CHAINS

BNB Smart Chain

BNB Smart Chain is where most of the world's USDT actually lives. Tab deploys here for users who already hold BSC-USDT and don't want to bridge to pay.

Stablecoin

Tab settles in BSC-USDT (18 decimals — note the difference from USDC on Base, which is 6). The token contract is the canonical Tether deployment.

A quirk to know about

BSC-USDT does not implement EIP-2612 permit. That means the first interaction with the router requires a normal approve transaction, and the user needs a small amount of BNB to pay for it. After that, all subsequent payments are gasless via the relayer.

Block time and finality

Three-second blocks. Tab waits for one confirmation; the indexer retries if a reorg invalidates the block.
