Project Context

Integrated into the launch of a new BPCE Group entity dedicated to digital assets, I led a dual effort: on one side, the technical development of a Web3 interface; on the other, an in-depth legal study on electronic signature compliance.

Developed Solution

On the technical side, I designed a Web3 interface with wallet and NFT integration (Next.js, React, TypeScript) and conducted a benchmark of major Ethereum node providers. On the legal side, I analyzed eIDAS, DSP2, and GDPR standards to secure signature processes in a banking context.

Regulatory Framework

Civil Code

Articles 1366 to 1368 on electronic evidence

eIDAS

European regulation on digital identity

DSP2

Strong authentication for payments

GDPR

Personal data and privacy

Conclusion

This project illustrates the value of a hybrid approach to support innovation in regulated sectors: Web3 technical architecture, user experience, and legal requirements combined in a single expertise.
