The challenge
What needed to change.
Krown needed one trading product for two groups: native Krown users and traders coming from other EVM chains.
Split apps
Swaps and bridges usually live in separate apps, each with its own approvals.
Hidden costs
Fees, routing and slippage often appear only after the user has committed.
Opaque bridges
Most bridges don't show both sides of a cross-chain transfer.
The engineering decision
A narrow bridge, on purpose.
The initial bridge corridor connects ETH, USDC and USDT between Ethereum and Krown using Hyperlane. Restricting the initial corridor reduced the number of integrations to test and operate, rather than spreading the launch across many routes. The platform separates trading, routing and bridge integrations so further corridors can be added without rebuilding the whole interface.
What VTS delivered
From decision to delivery.
