What it moves
The bridge carries USDT only, between BOT Chain and three networks:
These are the destination chain IDs the bridge contracts reported on 2026-10-02. Read them yourself with the script in Limits and fees. The testnet bridge works end to end: on 2026-10-02, 11 USDT deposits from BOT Chain testnet arrived on BSC testnet in under a minute. Rehearse on testnet before you bridge on mainnet. BOT Chain runs a bridge app at bridge.botchain.ai, and its own bridge docs cover the design.
Lock and release
The bridge doesn’t mint wrapped tokens. Each side holds a pool of real USDT:- Bridging out, you lock USDT in the router on BOT Chain, and the gateway on the destination chain releases the same amount, minus the fee, from its own balance.
- Bridging in, you lock USDT in the gateway on the other chain, and the router on BOT Chain releases it to you.
The contracts
All addresses, and the USDT resource ID that
deposit needs, are in Contract addresses.
Decimals change between chains
USDT has 6 decimals on BOT Chain, Ethereum and Tron, but 18 on BNB Smart Chain. You always pass the BOT Chain amount (6 decimals) todeposit. The bridge converts it. When you check what arrived on BNB Smart Chain, format it with 18 decimals. See USDT and decimals.
Fees and limits
Bridging out costs a percentage of the amount with a minimum, and has a minimum and maximum amount. BOT Chain’s docs say bridging in has no bridge fee. These values live in the contracts and can change, so read them before every transfer. See Limits and fees.Next steps
