Cryptact starts support for the Sei chain, realizing automatic profit and loss calculations for DeFi transactions.

## Features Realized with Sei Chain Support

The automatic profit and loss calculation service for cryptocurrencies "Cryptact" announced on the 29th that it has started supporting the Layer 1 blockchain "Sei."

Users can now automatically retrieve their deposit and withdrawal history on Sei simply by syncing their wallet address, allowing for consistent processing up to the necessary tax-related profit and loss calculations.

With this response, complex transactions such as swaps, staking, and liquidity provision on Sei will be automatically recognized and appropriately categorized. A significant feature is that it greatly reduces the work that previously required manual record-keeping and calculations.

In Japan, cryptocurrency transactions are required to calculate gains and losses accurately as miscellaneous income, making tax preparation a complicated task, especially for DeFi users. With the support of the Sei chain by Cryptact, the time and effort required for this task can be significantly reduced.

Realization through collaboration with KudasaiJP and Omakase

The support for the Sei chain this time was achieved in collaboration with the Web3 community "KudasaiJP" and the technical subsidiary Omakase Inc.

These organizations and Cryptact are jointly advancing the expansion of the corresponding blockchain and have also been active in answering community members' questions about cryptocurrency taxation and tax returns through AMA broadcasts on social media and live streaming on YouTube.

Future developments

This collaboration plays an important role in providing a solution that allows users to easily perform profit and loss calculations in the expansion of the Web3 project ecosystem. The community will be able to conveniently utilize the new blockchain early on, enabling efficient and strategic investment activities.

Pafin Corporation is committed to promptly responding to user feedback and requests, and will continue to advance its support for the latest blockchain technologies, with the aim of providing a seamless profit and loss calculation service.
