Prerequisites
1
User Creation
Every flow starts by creating a user record in Saber’s system. This gives you a
user_id that every subsequent action — KYC, bank linkage, transactions — is tied to, letting you map Saber users back to your own internal user records. See User Creation.2
KYC
Users must complete KYC before transacting. Depending on the corridor, this happens through a hosted widget, KYC Sharing (if you’ve already collected KYC yourself), or a KYC Partner URL. See User KYC.
3
Bank Account Linkage
Users need a linked, approved bank account before offramp payouts can go out, or before certain onramp payment methods (like USD’s ACH pull) can be used. Depending on the currency, this happens through a direct API call or a hosted widget. See Bank Account.
Ongoing capabilities
Alongside these prerequisites, two things apply continuously to a user’s account rather than as a one-time setup step:Wallet Operations
Each user has a wallet within Saber’s system that holds their crypto balance. Wallet operations cover checking balance and, where applicable, depositing or withdrawing from that wallet.
User Limits and EDD
Every user has a transaction limit. Once reached, no further transactions can be created until Enhanced Due Diligence (EDD) is completed to raise it — either through a hosted EDD widget or a Partner URL flow, depending on the corridor.
