Fireblocks capabilities in SDK.finance
The integration extends SDK.finance with Fireblocks digital asset platform integration capabilities that allow teams to launch and operate onchain payment products using secure custody, controlled execution, and ledger-based accounting, without embedding blockchain complexity into the core system.
Onchain deposits with ledger-level validation
The fireblocks digital asset platform integration enables onchain deposits to be processed with blockchain confirmation checks before balances are updated. This ensures ledger consistency even in cases of delayed confirmations or blockchain reorganisation.
Policy-controlled onchain withdrawals
SDK.finance enables onchain withdrawals using fireblocks infrastructure for crypto PSPs onchain payments, combining internal authorisation, limits, and holds with secure onchain execution and vault liquidity checks.
Operational control over non-standard blockchain flows
The platform supports controlled handling of exceptional onchain scenarios, including missing callbacks, conflicting transaction states, and delayed finality. This allows operations teams to resolve issues without compromising accounting accuracy.
Vault-based treasury and automated rebalancing
Fireblocks supports a structured hierarchy of vault accounts, and the SDK.finance integration is designed to work natively with this model. User and treasury vaults operate within a single custody structure, while rebalancing and fund movements are handled automatically through Fireblocks policies.
Developer-friendly crypto infrastructure
SDK.finance provides a developer-friendly crypto infrastructure where Fireblocks is responsible for custody and signing, while all balances, limits, fees, and workflows remain in a single ledger-driven system. This simplifies how teams launch onchain payments products.
Off-chain internal asset movements
Internal transfers between accounts are executed entirely inside SDK.finance without invoking Fireblocks. This allows high-volume asset movements without onchain dependency or additional custody operations.
