Before starting
- Register as a merchant.
- Set up your authentication token — see Configuring Your Keys.
- Register your users with Saber — see Merchant User Flow.
Onramp
Two ways to onramp once a client has deposited fiat with Saber:- Pool wallet: Crypto is onramped to a pooled wallet held with Saber, via internal transfer with no gas fees.
- External wallet: Crypto is onramped to an external wallet you specify, via an on-chain transfer (gas fees apply).
Offramp
Two scenarios:- Merchant transfers crypto to a Saber wallet (gas fees apply):
- Pre-fund: Load the user’s wallet with stablecoins first, then initiate the payout.
- Post-fund: Initiate the payout first; settlement happens once stablecoins are received.
- Merchant has a Saber Pool wallet: Crypto moves from your Pool wallet to the user’s Saber wallet as an internal transfer — no gas fees.
KYC
Two ways to keep users compliant with local jurisdictions:- KYC via Saber SDK: Users complete KYC through our industry-standard partners.
- KYC sharing: If you’ve already verified a user, share it with Saber to avoid a duplicate KYC step:
- KYC Sharing APIs: Share pre-verified KYC details in encrypted form.
- Tri-party agreement: For supported partners, a three-way agreement between Saber, you, and the KYC provider enables a seamless information flow.
