Overview
Account abstraction separates account logic from keys, enabling programmable accounts. We implement ERC-4337 infrastructure and applications: smart account contracts and modules, bundler and paymaster integration or operation, gas sponsorship policies, session keys and SDKs that let product teams add AA features without deep protocol knowledge.
Common use cases
- Gasless onboardingSponsor users' first transactions.
- Pay gas in stablecoinsUsers pay fees in tokens they hold.
- Programmable permissionsLimits and session keys for apps.
- AA infrastructureBundlers and paymasters for an ecosystem.
Quick answers
Account Abstraction Development at a glance
The essentials in brief. Every project is scoped individually — ask us for specifics.
- What is account abstraction development?
- ERC-4337 account abstraction — smart accounts, bundlers, paymasters and UX that removes crypto friction.
- Who is it for?
- Typically exchange operators, brokers, fintechs and Web3 companies launching trading, wallet, custody or on/off-ramp products.
- What does Shivacha provide?
- Smart account modules
- Bundler integration
- Paymasters
- SDKs
- Policy controls
- Monitoring
- Which technologies are used?
- ERC-4337, Account Abstraction, MPC Cryptography, WalletConnect, Viem, Wagmi — chosen to fit your stack and constraints.
- How does the process work?
- Custody model → Account & key design → Wallet services → Client apps → Security testing.
- What affects the cost?
- White-label configuration vs custom modules
- Number of assets, chains and trading pairs
- Custody model and provider
- Liquidity, fiat on/off-ramp and KYC integrations
- Mobile apps and admin scope
- Security testing and operational requirements
- How long does it take?
- White-label implementations typically take 2–5 weeks of software work depending on product and customisation; advanced custom platforms 4–8+ weeks. Licensing, banking, custody and liquidity partner onboarding run on their own timelines.

Delivery
How an engagement runs
- 1
Custody model
Custodial, non-custodial or hybrid — and who holds which key material.
- 2
Account & key design
Account type, key generation, storage and recovery flows.
- 3
Wallet services
Indexing, transaction building, simulation and fee management.
- 4
Client apps
Onboarding, asset views, send/receive, dApp connectivity.
- 5
Security testing
Threat modelling, penetration testing and recovery drills.
Security
Security built into delivery
Controls we apply by default on this kind of work — not a separate phase at the end.
Wallet segregation
Hot/cold tiers, withdrawal limits and approval quorums.
Custody integration
MPC, multisig or HSM-backed providers — keys never in application code.
Ledger reconciliation
Internal balances reconciled against on-chain and partner records.
Admin controls
Role-based access, maker-checker approvals and full audit trails.

Frequently asked questions
What is ERC-4337?
An Ethereum standard for account abstraction that uses UserOperations, bundlers and an EntryPoint contract, without changing the base protocol.
How do you prevent paymaster abuse?
With sponsorship policies, rate limits, allowlists and budget caps.
Custodial or non-custodial?
Custodial wallets suit regulated financial products and simpler onboarding, usually with a licensed custodian. Non-custodial wallets give users full control. Hybrid MPC and smart-account designs sit between the two.
What is account abstraction?
Account abstraction (notably ERC-4337) lets wallets be smart contracts, enabling features like gas sponsorship, batched transactions, spending limits, session keys and flexible recovery.
