Tokenization and identity
ERC-3643 token systems, on-chain identity and transfer restrictions. Translate the product's requirements into explicit contract behavior and testable rules.
SOLIDITY & SMART CONTRACTS
Smart contracts built for the full lifecycle.
I'm Adam Boudjemaa, a Solidity developer and former blockchain technical lead. I build token infrastructure and smart accounts, with the testing, permission design and upgrade paths your team needs to operate them.

Where I can help
Modular smart accounts
ERC-4337 account abstraction and ERC-7579 modules. Review authorization, session boundaries, execution paths and how the account integrates with your application.
Audit preparation and remediation
Foundry tests, fuzzing, invariants and static analysis. Document assumptions, reproduce findings and resolve them with tests the team can keep running.
The work behind the profile
Authorship you can verify
I'm a named author of ERC-3643, first author of ERC-6960 and co-author of ERC-7410. The standards pages link to the original specifications and distinguish their status.
Read the standards and author recordsProduction smart-account engineering
At Biconomy, I led a team working on Nexus modular smart accounts, core Solidity and Yul optimizations, the Foundry test suite and audit coordination. Earlier, I built compliant token infrastructure at Tokeny.
Review my experience and CVHow we start
- Map the assets, actors, trust assumptions and upgrade authority.
- Define invariants and expected failure behavior before implementation.
- Build and test the contract paths with integration and fuzz coverage.
- Prepare the review package, fix findings and document deployment operations.
Before you get in touch
Can I hire you as a freelance Solidity developer or for a permanent role?
Yes. I'm open to scoped Solidity missions and permanent protocol engineering roles. Share the product, chain, existing repository, delivery window and budget or salary range.
Do you work on ERC-3643 and real-world asset tokenization?
Yes. I'm a named author of ERC-3643 and built compliant token and on-chain identity infrastructure at Tokeny. My engineering scope covers contract behavior, permissions, transfer restrictions and integrations; legal requirements need to come from your legal and compliance team.
Does working with you replace an independent security audit?
No. I can design and implement contracts, prepare the codebase for review and remediate findings. The scope should separately identify any independent audit, its reviewer and the release requirements.
Are you available remotely and in French?
I'm based in France and work in French and English. I'm open to remote work, on-site engagements and relocation depending on the scope and role.
