Quickstart

Buy crypto with fiat and have it deposited into a wallet of your choice. Saber offers two integration approaches — a web-hosted SDK, or the onramp APIs — and lets you choose whether to keep a pool account with Saber or transfer to an external wallet. Flowchart of the onramp quickstart flow: view payment method and beneficiary details, create a buy order, convert fiat to crypto, deposit crypto in the user's account, and wait for a completed callback

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.

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.
