Overview

Through this guide, you can buy crypto with fiat and have it deposited into a wallet of your choice.

Saber offers two approaches to integration:

A web-hosted SDK
Saber onramp APIs

In addition to this, Saber also facilitates the merchant to choose whether to keep a pool account with Saber or have crypto transferred to an external wallet address.

SDK versus API

Feature	API Flow	SDK Flow
Ease of Integration	Requires custom development with multiple API calls (authentication, KYC, payments).	Quick setup with prebuilt UI and minimal coding effort.
Customization	Full control over the user interface, branding, and workflows.	Limited to predefined UI and flows offered by the SDK.
Error Handling	API errors must be handled manually (e.g., authentication failures, KYC rejections).	SDK abstracts most errors and only requires handling final transaction statuses.
Implementation Time	Longer due to custom development and testing.	Faster setup with ready-to-use components.

Keeping crypto in Saber or transferring it to an external wallet

Aspect	Keeping Crypto in Saber Pool	Transferring to an External Wallet
Security	Safely stored with enterprise-grade encryption.	Full control but requires secure management of private keys.
Convenience	Instant access for transactions within Saber’s ecosystem.	Additional steps are required to transfer funds for transactions.
Fees	No network fees; standard network fees for withdrawals.	Network fees apply for all transfers, plus potential wallet fees.
Flexibility	Limited to Saber-supported cryptocurrencies.	Can be used across multiple platforms and wallets.
Control	Saber manages private keys and recovery processes.	The user is fully responsible for private key management.
