Overview
Wallet APIs let developers add wallet functionality to their products without building infrastructure: create wallets, derive addresses, query balances, build and send transactions and receive events. We design and build wallet APIs and SDKs with strong authentication, idempotency, webhooks and clear documentation — for wallet-as-a-service platforms or internal platform teams.
Common use cases
- Wallet-as-a-service APIExternal developers embedding wallets.
- Internal wallet platformShared wallet services across teams.
- Payment APIProgrammatic crypto payments.
- Game developer SDKIn-game wallets for studios.
Quick answers
Wallet API Development at a glance
The essentials in brief. Every project is scoped individually — ask us for specifics.
- What is wallet API development?
- Wallet APIs and SDKs for developers — create wallets, manage assets, send transactions and receive webhooks.
- 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?
- API design
- Authentication
- Idempotency
- Webhooks
- SDKs
- Documentation
- Which technologies are used?
- Account Abstraction, ERC-4337, 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.

Architecture
Engineered right from day one
The layers we typically design for wallet infrastructure, adapted to your stack and partners.

- Transaction simulationUsers see what a transaction will do before signing.
- Chain abstractionUnified balances and gas handling across networks.
- Secure storagePlatform secure enclaves and hardware-backed keys.
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
Custodial or non-custodial wallet APIs?
Both are possible: custodial APIs manage keys server-side via custody providers; non-custodial SDKs keep keys on user devices.
Is there a sandbox?
Yes — testnet-backed sandboxes let developers build without real funds.
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.
