Manage wallets, sign transactions, and interact with the blockchain from your server. Node.js, Python, Java, or any language via the SDK. Your application holds the keys, your server controls the flow.
In a custodial architecture, the server — your backend — manages the keychain on behalf of users or systems. The private keys never leave your server. Users don't need to manage seeds or sign transactions themselves.
Enterprise applications, ERP integrations, IoT gateways, automated trading bots, SaaS platforms, and payment processing. Any scenario where the end user shouldn't touch cryptographic keys.
The ATSHI SDK handles key derivation, transaction building, signing, and submission — your code just calls the API. No cryptographic expertise required. Import the package, create a keychain, build a transaction, submit. Four lines of code to go from zero to on-chain.
Your ERP writes supply chain data directly to the blockchain. Each batch, each shipment, each quality check — automated, no human in the loop.
Thousands of sensors push data on-chain via a gateway server. Bulk provisioning, automatic key management, lightweight protocol.
Process blockchain payments server-side. Build payment flows without exposing private keys to the frontend.
Your SaaS creates and manages wallets for each customer. Users interact with blockchain features through your UI — they never see a seed phrase.
Trading bots execute on the Confidential DEX programmatically. Server-side signing for high-frequency operations.
Automated smart contract deployment, testing, and management pipelines. Integrate blockchain operations into your existing DevOps workflow.
npm package, full async/await API, TypeScript types included.
npm install @atshi/sdk
pip package, sync and async clients.
pip install atshi-sdk
Maven/Gradle package. Enterprise-grade SDK for JVM backends and Android services.
com.atshi:sdk:1.0.0
Language-agnostic HTTP API for any language or platform.
api.atshi.network/v1
npm install, pip install, or use the REST API directly. One dependency, zero configuration. You're ready in under a minute.
Generate a keychain server-side. Derive service keys for each use case — payments, traceability, IoT, trading. Each service gets its own isolated key pair.
Construct transactions using the SDK. Sign with your server-managed keys. The SDK handles serialization, hashing, and cryptographic signing automatically.
Send signed transactions to the ATSHI network. Get confirmation with immediate finality. No waiting for block confirmations — confirmed is confirmed.
Store keys in HSM, AWS KMS, HashiCorp Vault, or encrypted at rest. Never in plaintext. The SDK integrates with standard key management infrastructure out of the box.
Restrict which services can sign transactions. Use IAM roles, API keys, or mTLS. Principle of least privilege — each service signs only what it needs to.
Every transaction is signed and recorded on-chain. Full traceability of server-side operations. Immutable proof of who signed what and when.
Integrate ATSHI into your server-side architecture. Full SDK, immediate finality, enterprise-grade key management. Your code, your keys, our network.
