Overview
Finitum Bridge is a cross-chain bridge that lets you move supported tokens between Binance Smart Chain and Cardano in either direction1. You connect a wallet, pick a token from a fixed supported list, and the bridge issues a matching version of it on the other chain. It is built for holders of a handful of specific tokens who want to use them on Cardano instead of Binance Smart Chain, or move them back.
The bridge is operated by Staking Rocks!, the team behind the PHRCK Cardano stake pool2. It began as a way to deliver rewards from an outside network to that pool's supporters, since no existing tool could carry those particular tokens onto Cardano3. The interface is labelled beta.
Key Features
- Two-way token transfers. Move supported tokens from Binance Smart Chain onto Cardano, then move them back the same way, without using a centralized exchange1.
- Lock-and-issue model. When a token leaves Binance Smart Chain, it is locked there and a matching token is created on Cardano. Reversing the trip destroys the Cardano token and releases the original3.
- Familiar Cardano wallet support. Connects to common browser wallets including Typhon, Eternl, Nami, Flint, Gero, and Yoroi for the Cardano side of a transfer4.
- A fixed set of supported tokens. Works with a defined list of tokens, starting with BUSD, UMB, BHC, and HPS, rather than accepting any asset1.
- Saved transfer history. A record of your transfers, including ones still in progress, stays visible even if you close and reopen the page4.
What to Expect
You land on a simple bridge screen where you choose a direction, pick a supported token, and enter an amount. Sending a token into Cardano happens in two parts: first you approve and send the token from Binance Smart Chain, then you switch to your Cardano wallet and claim the matching token there. The claim step needs a small amount of ADA, the Cardano network token, already in your wallet, because every Cardano transaction requires a minimum ADA balance.
After you send from Binance Smart Chain, the bridge waits for that network to confirm the transaction before the claim becomes available, so there is a short wait between the two steps4. If you close the page, your pending transfer is still there when you return.
The tokens you send are held by the operator, Staking Rocks!, rather than by automated on-chain code5. The interface is labelled beta.
