THE agency to go for blockchain development. Super experienced and highly professional team. Love to work with them.
Account Abstraction Development
Smart accounts, gas sponsorship and recovery that survive contact with real users. We have shipped account abstraction to production alongside Boba Network's team, including natively inside MetaMask.
Cancel any week. Last week refunded if we didn't blow you away. No hours tracked.
- 3 SDKs Backend, contract and frontend, reverse-engineered from undocumented infrastructure and still live See the case study
- MetaMask Account abstraction brought natively into the wallet users already trust See the case study
What We Do
Account abstraction is easy to demo and hard to operate. The difficulty is not the smart account, it is sponsorship economics, abuse, and recovery when a real user loses a device.
Smart Account Implementation
ERC-4337 accounts, either from a proven base or custom where you need it.
- Safe, Kernel and ZeroDev evaluated against your case
- Custom validation logic where the base does not fit
- Deterministic addresses and counterfactual deployment
- Migration from existing EOA users
Paymasters and Sponsorship
Gasless is a business decision before it is a technical one.
- Sponsorship policy tied to real unit economics
- Abuse prevention and rate limiting
- ERC-20 paymasters for pay-in-token flows
- Spend caps, alerting and kill switches
Bundler and Infrastructure Integration
The parts that break quietly in production.
- Bundler selection and fallback
- EntryPoint version handling
- UserOperation debugging and observability
- Self-hosted versus managed trade-offs
Session Keys, Passkeys and Recovery
The UX that makes a smart account worth having.
- Scoped session keys with real expiry
- Passkey and WebAuthn signers
- Social and guardian recovery
- Device loss handled as a normal case
Production Support
We have run this against infrastructure that changed under us without notice.
- Monitoring on sponsorship spend and failure rates
- Upgrades across EntryPoint revisions
- Incident response under retainer
- SDK maintenance as the spec moves
How we approach account abstraction
We engineered Boba Network’s three-layer Hybrid Compute SDK suite together with the Boba team, against infrastructure with no documentation and no specs, patching live infra errors as we went, and then brought that stack natively into MetaMask with them. That is the difference between having read the spec and having operated it. Our engineering notes on the trade-offs are in account abstraction in production, and the hub page is Web3 and blockchain development.

What clients say
For technical questions on blockchain and NFT, I always come back to Kevin. He has familiarized himself very well in this area, and the expertise he brings is certainly essential for projects like these. I can only recommend everyone get in touch with Kevin on these topics.
